(5) Applicable Wire Sizes

From the specification for .070 series contacts used with this housing:

Wires shall be AV or AVS type per JIS C 3406.

(6) Mating and Accessories

The 173090-2 plug housing assembly mates with the corresponding cap housing (e.g., 173063 for 2-position). A seal ring is attached to the plug housing to provide water-tight connection when mated. Rubber plugs are used on wires next to the crimp for sealing. Cavity plugs are used for unused cavities. Compatible receptacle contacts include 171630 and 171661 series. Rubber plugs and cavity plugs are available in NBR (nitrile butadiene rubber) or silicone (900324, 900325).

(7) Conclusion

The 173090-2 is a 2-position, sealable, black female terminal housing for wire-to-wire power applications in 12 V automotive systems. It is part of the ECONOSEAL “J”-II series, offering reliable performance from -30°C to +105°C. The housing is made of glass-filled PBT with UL 94HB flammability rating. It meets RoHS, ELV, REACH, and low halogen requirements. When assembled with appropriate contacts, rubber plugs, and seal ring, it provides water-tight sealing tested to 49 kPa. The connector is serviceable and packaged in bags of 100 pieces.
