The TE 1-929170-4 is the 4-position, single-row receptacle housing from the Micro Quadlok series. The black PBT glass-filled insulation material gives it good chemical resistance and dimensional stability for underhood or industrial environments.
The 2.54mm pitch and single-row layout are standard for this series, so the plug counterpart will have the same 4-position count and 0.100" spacing. For the crimp terminals, you need the TE female socket contacts designed for the Micro Quadlok system — the housing accepts them via a standard crimp termination. The 1-1376477-6 is a different connector family — it's a 6-position plug with a 2.50mm pitch and red PA66 housing, not a direct cross or substitute for this 4-position 2.54mm receptacle. No official second-source or cross-reference exists for the 1-929170-4.
