1. SCOPE

1.1. Content

This specificat ion covers performance, tests and qual it y r equirements f or the Ty c o E lectroni c s MT A -|100 connect or system. Thi s system is m ass terminated usi ng insulati on displac ement technology on

.100 inch centerli nes and mates with .025 i nc h square posts providi ng a r eliabl e int er c onnec ti on

between wir es and posts mounted on printed c irc uit boar ds. The standard system i s availabl e in 2

through 28 posi ti ons. The MT A - 100 c onnec tor system i s designed t o be terminated to 28 AWG t o 22

AWG wire, tin plated UL style 1007, 1061 or wir e whic h specifies PVC i nsul ati on with temper ature

rating compati ble wit h specified operat ing t emper atures, see Fi gur e 4. Wir e shal l meet appli c ati on

4.1. Quali ficati on Testing

A. Sample Selection

Sampl es shall be prepared in acc or danc e with appl icable I nstr uc ti on S heets and shall be selec ted

at random from c ur r ent production. Test gr oup 1 shal l consi st of 5, 6 posit ion standard tin- lead

plated samples and 5, 6 positi on gold plated sampl es. A ll samples shall be termi nated to the

m aximum wire si z e and mounted on printed c irc uit boar d P N 93- 660017 ( see Figure 5). Test

group 2 shall consist of 3, 10 posit ion standard tin- lead plated sampl es ter minat ed to 28 AWG

wire and mounted on pr int ed c irc uit boar d P N 93- 660652; and 3, 10 posi ti on standar d ti n- lead

plated samples terminat ed to 22 AWG wire and mounted on printed c irc uit boar d P N 93- 660651

(see Fi gur e 5) . Test gr oup 3 shal l consi st of 3, 10 posit ion gol d plat ed sampl es ter minat ed to 22

AWG wire and mounted on printed circ uit boar d P N 93- 660017. Test gr oup 4 shal l consi st of 5

unm ounted 24 posit ion standard ti n- lead plated sampl es ter minat ed to the maximum wire siz e.

Test group 5 shal l consi st of 6, 10 posit ion standard tin- lead plated sampl es ter minat ed to 28

AWG wire; 6, 10 posi ti on standar d tin- lead plated sampl es ter minat ed to 24 AWG wire; and 6, 10

position standard ti n- lead plated sampl es ter minat ed to 22 AWG wire. All sampl es shall be

unm ated and unmounted. Test gr oup 6 shal l consi st of 5, 6 position . 100 inch fric tion lock ti n- lead

plated headers.

B. T est S equenc e

Quali ficati on inspection shall be verified by t esting sam ples as spec ified in Figure 2.

4.2. Requalificati on Testi ng

If c hanges significant ly affec ti ng form , fi t or func ti on ar e made to the pr oduc t or manufac turing

process, product assurance shall coordinat e r equalificat ion t esting, c onsi sting of all or par t of t he

ori ginal testing sequence as determined by development /product, quality and r eliability engineering.

4.3. Acceptance

Acceptance is based on verificati on that the product meets requirements of F igure 1. Failures

att r ibut ed to equi pment, test setup or operator deficiencies shall not di squal ify pr oduc t. When product

fai lure oc c ur s, c or r ec ti ve action shall be t ak en and sampl es resubm it ted for qualificat ion. Testi ng to

confirm cor r ec ti ve action is requir ed before resubmittal .

4.4. Quali ty Confor manc e Inspection

The applicable quality inspection plan will specify the sampling acceptable quality level to be used.|Dimensi onal and func ti onal requirements shall be in accor danc e with the applicable product drawing

and this specificat ion.
