MIL-PRF-31031/1B
Leakage current: Not applicable.
Cable group II: 500 volts rms minimum.
Cable group VI: 670 volts rms minimum.
Cable retention force: See table II.
Coupling mechanism retention force: Not applicable.
Shielding effectiveness: Test procedure 066 of EIA 364: -85 dB minimum. This test needs to be
performed only during initial qualification, as long as the qualifying design, materials and manufacturing
procedures do not change.
RF transmission loss (dB maximum): This test needs to be performed only during initial qualification, as
long as the qualifying design, materials and manufacturing procedures do not change.
.03 √frequency GHz Test at a frequency between 9 and 12.4 GHz.
Porosity: Applicable.
Thermal vacuum outgassing: Applicable to space grade connectors only.
Flammability: Applicable to space grade connectors only.
Odor: Applicable to space grade connectors only.
Toxicity (offgassing): Applicable to space grade connectors only.
Safety wire hole pullout: Not applicable.
Part or Identifying Number (PIN): M31031/01 (see table I).
Group qualification: See table III.
NOTES:
1. If a connector manufacturer produces a connector that meets all the requirements for two or more
connector PIN's (within the same series and of the same environmental grade), the manufacturer
may receive qualification approval for two or more connectors PIN's qualifying the one connector.
It is not necessary that such connectors be in the same group. Each connector, however, must be
marked with its own PIN. For group qualification, the connectors must be of the similar design.
2. For qualification retention, where more than one part is listed in a group in this column, data may
be supplied on any of those parts in order to retain qualification for those parts in the
corresponding right hand column. The part does not necessarily have to be the part initially
qualified.
Supersession: This specification supersedes DSCC drawing 85073.
