The black thermoplastic polyester housing, glass-filled, carries a polarizing key to prevent mis-mating in multi-connector harness layouts.
The One Thing You Need to Know First: Contacts Not Included
This housing ships empty — no contacts, no terminals. That is the single most common sourcing miss on this part: a buyer lands the housing, receives it, and finds no metal. Confirm the BOM has the correct terminal part number alongside the 1-179552-4 before committing the line.
The 5.08 mm pitch (0.200") is the defining footprint parameter. It matches the Dynamic D-3200 PCB header pin spacing — a 4-position header at the same pitch. The single-row layout keeps the housing narrow for tight harness routing.
No official second-source or cross-reference exists; the Dynamic D-3200 series is proprietary to TE Connectivity.
Why This Housing Is Not a Cross to the Dynamic D-5000
A buyer searching for a functional second-source might land on the 1-1703532-1, another TE plug housing but from the Dynamic D-5000 series. The pitch difference alone kills the swap: 5.08 mm on the D-3200 vs 9.50 mm on the D-5000. That is a different header footprint entirely — the two are not form-fit-function interchangeable. Stick with the D-3200 series for this housing; the D-5000 is for higher-current circuits where the wider pitch is needed.
