(5) Applicable Wire Sizes (for .070 series tab contacts used with this housing)

From the specification for .070 series tab contacts:

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

(6) Mating and Accessories

The 173063-2 cap housing mates with the corresponding plug housing assembly, such as 173090 (2-position plug housing). The plug housing carries a seal ring to provide water-tight connection when mated. Compatible tab contacts include 171631 and 171661 series. Rubber plugs are used on wires for sealing when assembled with the plug housing. Cavity plugs are available for unused cavities. The cap housing itself is unsealable.

(7) Conclusion

The 173063-2 is a 2-position, black, male terminal cap 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 PBT with UL 94HB flammability rating. It meets RoHS, ELV, REACH, and low halogen requirements. When mated with the corresponding plug housing and assembled with appropriate contacts and rubber plugs, the system provides water-tight sealing tested to 49 kPa. The connector is serviceable and packaged in bags of 100 pieces.
