retained in a plastic housing. The female (disconnect) end of the contact shall interface with 0.025
inch square (or round) pins on 0.100 inch centers.
3.4.1
3.4.2
Mating. The connector shall be capable of being mated or unmated by hand without the
use of special tools within the specified temperature range.
Workmanship. Connectors shall be uniform in quality and shall be free from burrs,
scratches, cracks, voids, chips, blisters, pin holes, sharp edges, and other defects that
will adversely affect life or serviceability.
Interchangeability. The connector shall be capable of mating with any appropriately
constituted male connector of the same population without degradation in performance.

3.5
Electrical Characteristics
3.5.1
3.5.2
Current Rating. The maximum current rating of the connector shall be 3.0 amperes DC
(2.5 amperes for multi-position assembly).
Contact Resistance. (see 5.1) The contact resistance shall not exceed the value
specified in Table 1, when measured in accordance with MIL-STD-202, Method 307. The
following details shall apply:

Contact Retention. (See 5.2) The contact pair shall not be dislodged from the housing
when an axial force of 3.0 pounds (1.5 pounds per contact) is applied in the direction of
insertion. The force shall be applied at a crosshead speed of 1 inch per minute using
fixture # MF 407.1. (See Figure 6)
Total Mating Force. The total force to mate the connector with an appropriate header
having properly configured (see Figure 2) 0.025 inch square pins shall not exceed the
value shown in Table II.
