The 2-position count is the first check against your BOM line. With a pitch of 0.122\" (3.10mm), this housing is wider than typical signal connectors, a deliberate choice for the current and voltage demands of a SQUIB firing circuit. ## Key Features: TPA and Lever Lock Two features set this housing apart for safety-critical use. The Terminal Position Lock (TPA) is a secondary lock that slides over the loaded terminals, confirming each crimped contact is fully seated and preventing it from backing out under vibration. The lever lock provides a positive, audible snap when mated with the corresponding header, giving a clear tactile confirmation that the connection is secure. In a SQUIB circuit, a partially mated connector is a failure mode you don't want. ## Operating Environment and Temperature Range The PBT insulation material handles the typical under-dash and interior environment well, including exposure to humidity and common automotive chemicals.","metaTitle":"TE Connectivity 1612121-1 SQUIB 2POS Plug Housing","metaDescription":"TE Connectivity 1612121-1 SQUIB 2-position plug housing. 3.10mm pitch, lever lock, TPA.
