38999-Style Series I, II, III Connectors*
38999-Style Specifications
After preloading to 3 pounds maximum, the force shall be applied at a rate of approximately 1 pound per second and maintained at full load for 5-10
seconds. No damage to contacts or insert shall result nor shall the contacts be dislocated from their normal position in the connector more than 0.012 inch
under the given load. Failure to meet these requirements shall be cause for rejection.
The following excerpts are some of the parameter requirements of the MIL-DTL-3899 Specication.
For qualication testing, mating halves shall be coupled and uncoupled, measuring the torques necessary.The torques required to couple and uncouple
mating connector halves shall fall within the limits specications as follows:
Connector halves shall be mated and unmated 250 times for Series II with ground ngers and 500 times for Series I and III at a rate not exceeding 300 cycles
per hour. The test may be performed by hand or by mechanical means, but the coupling ring shall be operated as in normal service. Failure to complete this
test because of mechanical malfunction shall be cause for rejection.
An insulation resistance test shall be performed on unmated connectors in accordance with MIL-STD-202, Method 302, Test condition B. Measurement shall
be made between three pairs of adjacent contacts and the shell. Failure to meet the minimum requirement of 50,000 megohms for Classes E, P, F, R, and
T shall be cause for rejection.
Wired, mated connectors shall be subjected to the vibration test of MIL-STD-202, Method 214, Test Condition II, except that the duration shall be one hour
in each plane. Receptacles shall be mounted on the vibration xture by normal means. All contacts shall be wired in a series circuit and 100-500 millamperes
of current shall be allowed to ow through the series circuit during vibration. Suitable means shall be employed to monitor the current ow and to indicate
any discontinuity of more than 1 microsecond. The wire bundle shall be damped to the nonvibrating points at least 8 inches from the rear of the connector.
Current discontinuity of 1 microsecond or more, disengagement of the mated connectors, evidence of cracking, breaking, or loosening of parts shall
be cause for rejection.
Wired mated connectors shall be subjected to one shock in each direction in each of three mutually perpendicular axes. The pulse shall be approximate half
sine wave of 300g ± 15% magnitude with a duration of 3 ± 1 milliseconds. Receptacles shall be mounted on a shock xture by normal means. All contacts
shall be wired in a series circuit and 100-150 ma. of current shall ow through the series circuit during shock. Suitable means shall be employed to monitor
the current ow and to indicate any discontinuity of more than 1 microsecond. The wire bundle shall be clamped to xed points at feast 8 inches from the
rear of the connector, Current discontinuity of 1 microsecond or more, disengagement of the mated connectors, evidence of cracking, breaking, or loosening
of parts shall be cause for rejection.
Mated connectors shall be placed in a container of water at approximately 20ºC and placed in an altitude chamber. All wire ends shall be located within the
chamber and exposed to the chamber atmosphere, but not submerged. The exposed wire ends shall not be sealed. A quantity of salt, 5 percent by weight,
shall be added to make the water conductive. The chamber pressure shall then be reduced to approximately one inch of mercury and maintained for thirty
minutes. The chamber pressure shall then be slowly returned to atmospheric. This shall be considered one cycle. Two additional cycles shall be performed. At
the end of the last cycle, while the mated connectors are still submerged, the Insulation Resistance Test (room temperature), and the High Potential Test (sea
level voltages) shall be performed upon the same circuits. Failure to meet an insulation resistance minimum of 2,000 megohms or any evidence of dielectric
breakdown or -ashover shall be cause for rejection.
Unmated connectors shall be immersed fully in the applicable uid specied below for 20 hours. After removal from the uid, each connector shall
remain for one hour in free air at room temperature.
a.) Jet fuel JP-4 to MIL-J-5624 b.) Aircraft lubricating oil to MIL-L-9236
Unmated connectors and individual contact samples shall be subjected to the soft spray of MIL-STD-202, Method 101, Test Condition 8 (tin plated, Class Y
receptacles-24 hours). Immediately after exposure, the surfaces of the specimens shall be thoroughly washed in tap water and dried in a circulatory oven at
a temperature of 38 ±3ºC (100ºF) for a period of approximately 12 hours. Any exposure of basis metal as a result of this test, shall be cause for rejection.
(Series I and 11, nish B; Series III, class W). The wired assembled plugs and receptacles shall be mated and unmated 50 cycles at a rate of 300 cycles per hour
maximum. The mating and unmating shall be accomplished so that the plug and receptacle are completely separated during each cycle. The connectors shall
then be subjected to the salt spray test in accordance with method 1001 of MIL-STD- 1344. The connectors shall be tested for 452 hours mated followed by
48 hours unmated. After the salt spray exposure the remaining number of durability cycles specied in 4.7.7 shall be completed.
Unmated receptacles shall be subjected to 10 cycles of thermal shock in the following manner:
The receptacle shall be suspended for 10 + 1 - 0 minutes in the center of a cold water both with a volume of approximately one cubic foot. No
dimension of the bath shall be less than 10 inches. The water temperature shall not exceed 4ºC (39.20ºF)
The receptacle shall be suspended for 10 1 - 0 minutes in the center of a hot water bath with a volume of approximately one cubic foot. No
dimension of the bath shall be less than 10 inches. The water temperature shall be not less than 94ºC (201ºF).
The time of transfer from one bath to the other shall not exceed 5 seconds. At the end of the tenth cycle, the receptacle shall have the excess moisture shaken
off and shall then be dried in a forced air oven at 66±5˚C for 15 ±1 minutes. Any evidence of damage resulting from this test shall be cause for rejection.

Product Safety and Warranty
1. MATERIAL CONTENT AND PHYSICAL
FORM
Electrical connectors do not usually contain
hazardous materials.
Electrical connectors and individual com-
ponents do not release or otherwise result
in exposure to hazardous chemicals under
normal conditions of use and fall under
the denition of “Article,” under the
Hazard Communication Standard, 29 CFR
1910.1200, and are not considered hazard-
ous materials.
Solder and uxes can be hazardous if inhaled
or absorbed through the skin and should
only be used as recommended by the manu-
facturer. Please consult your solder and ux
manufacturer for more specic application
recommendations.
2. FIRE CHARACTERISTICS AND ELECTRIC
SHOCK HAZARD
There is no re hazard when the connector is
correctly wired and used within the specied
parameters. Incorrect wiring or assembly of
the connector or careless use of metal tools
or conductive uids, or transit damage to
any of the component parts may cause elec-
tric shock or burns. Live circuits must not be
broken by separating mated connectors as
this may cause arcing, ionization and burn-
ing. Heat dissipation is greater at maximum
resistance in a circuit. Hot spots may occur
when resistance is raised locally by damage,
e.g. cracked or deformed contacts, broken
strands of wire. Local overheating may also
result from the use of the incorrect appli-
cation tools or from poor quality soldering
or slack screw terminals. Overheating may
occur if the ratings in the product Data
Sheet/Catalog are exceeded and can cause
breakdown of insulation and hence electric
shock. If heating is allowed to continue it
intensies by further increasing the local
resistance through loss of temper of spring
contacts, formation of oxide lm on contacts
and wires and leakage currents through car-
bonization of insulation and tracking paths.
Fire can then result in the presence of com-
bustible materials and this may release nox-
ious fumes. Overheating may not be visually
apparent. Burns may result from touching
overheated components.
3. HANDLING
Care must be taken to avoid damage
to any component parts of electrical connec-
tors during installation and use. Although
there are normally no sharp edges, care
must be taken when handling certain com-
ponents to avoid injury to ngers. Always
wear safety glasses to avoid potential injury
to eyes during cleaning, soldering, ber
preparation, etc.
Electrical connectors may be damaged
in transit to the customers, and damage
may result in creation of hazards. Products
should therefore be examined prior to instal-
lation/use and rejected if found to be dam-
aged. Proper lifting techniques shall be used
for handling shipping cartons.
4. DISPOSAL
Please recycle, reclaim or dispose of connec-
tors and individual components in accor-
dance with local, state and federal laws.
Incineration of certain materials may release
noxious or even toxic fumes..
5. APPLICATION
Connectors with exposed contacts should
not be selected for use on the current sup-
ply side of an electrical circuit, because an
electric shock could result from touching
exposed contacts on an unmated connector.
Voltages in excess of 30 V ac or 42.5 V dc are
potentially hazardous and care should be
taken to ensure that such voltages cannot
be transmitted in any way to exposed metal
parts of the connector body. The connector
and wiring should be checked, before mak-
ing live, to have no damage to metal parts
or insulators, no solder blobs, loose strands,
conducting lubricants, swarf, or any other
undesired conducting particles. Circuit resis-
tance and continuity check should be made
to make certain that there are no high resis-
tance joints or spurious conducting paths.
Always use the specied application tools,
cleaning materials and assembly instructions
documented in the Data Sheet/Catalog. Do
not permit untrained personnel to wire,
assemble or tamper with connectors. For
operation voltage please see appropriate
national regulations.
