What This Economy Power II Housing Is and Where It Goes
The Procurement Trap: Contacts Are Not Included
The listing plainly states 'Contacts Not Included' — that's not a footnote, it's the main event for anyone filling a BOM. This housing ships empty. A common miss is quoting the housing and assuming contacts come with it. They don't. Factor the terminal order code and quantity into your RFQ.
Mating Header and Contact Compatibility
This receptacle mates with any Economy Power II header that shares the 3.96mm pitch and the latch-holder locking feature — typically a shrouded or unshrouded pin header with the same circuit count. The header's latch ramp engages the housing's latch holder for positive retention. For the crimp terminals, use the TE Economy Power II female socket contacts (order code varies by wire range; the series uses standard 0.156" pitch terminals).
What the 3.96mm Pitch and Latch Holder Mean for the Build
The 0.156" (3.96mm) pitch is the standard Economy Power II spacing — it gives enough creepage for the voltage this series typically sees (rated up to 600V in the family, though this housing's voltage rating isn't separately stated). The latch holder is the fastening type: it's a molded ramp on the housing that snaps over a matching latch on the header. That's a vibration-resistant mate — the latch keeps the pair together under cable strain or machine vibration, which is why you see this series in power supplies and industrial controls. The single-row, 3-position layout keeps the harness narrow; three circuits for a simple power-in/return/ground run.
