The 5.90 mm row spacing is wider than a typical 2.54 mm dual-row header, so the mating header footprint needs a larger board keep-out zone than a standard signal connector.
Sourcing the Right Contacts
The housing ships empty — the note says Contacts Not Included. The terminal gauge range and specific part number are not listed in this record, so confirm the wire size and terminal order code against the TE Multi-Lock application tooling drawing before committing the BOM line. The housing accepts the terminal on its own; no secondary locking device is mentioned in the spec.
How It Compares to a Same-Series Peer
Against the 6-position 1-2069882-6 (also a dual-row receptacle, but natural colour and 7.62 mm row spacing), the 174931-1 offers 8 positions at a tighter 5.90 mm row spacing. The 1-2069882-6 uses a glass-filled thermoplastic versus the straight PBT of the 174931-1. Both are free-hanging crimp receptacles with contacts not included.
