The TE 316088-1 is a 4-circuit, single-row receptacle housing from the Signal Double Lock series. The natural PA66 (Nylon 6/6) insulation handles operating temperatures from -30°C to 105°C, which covers most indoor industrial and consumer equipment environments.
Why the 'Contacts Not Included' Note Matters for Your BOM
The first thing to know about the 316088-1: it ships as an empty shell. The 'Contacts Not Included' note on the spec line means you need to source the tab-style crimp terminals separately — TE's Signal Double Lock terminal family. A common miss is ordering just the housing and having a harness stop because the terminals aren't on the pick list. Factor the terminal order code into your BOM from the start.
Lifecycle and Sourcing — Still in Production
It's a current-production part, not a last-time-buy or obsolete line.
This is a tab-style receptacle housing — it mates with the matching Signal Double Lock header (pin header, same 0.098" pitch). Termination is crimp, so you'll need the correct TE hand tool or automatic press for the terminal.
