AI Summary

1-178128-4 by TE Connectivity AMP Connectors: 4 Position Rectangular Housing Connector Receptacle Black 0.200" (5.08mm).

The 2-178128-4 is a direct mechanical sibling from the TE Dynamic D-3200 series with Y-keying instead of X-keying. It maintains identical dimensions, contact crimp system, and electrical characteristics, but requires a Y-keyed mating header or tab.

  • Same Dynamic D-3200 series family, body dimensions, 5.08 mm pitch, and 4-position single-row layout
  • Uses identical crimp socket contacts and mates with the same headers/tabs
  • Y-key mechanical polarization prevents mating with X-keyed male headers/tabs

The Phoenix Contact 1376524 (D32PC series) is an alternative 4-position, 5.08 mm pitch crimp receptacle housing with X-keying designed for wire-to-board power and signal applications. It provides a functional second-source replacement, though crimp contacts and mating headers should be verified for cross-compatibility.

  • Same 5.08 mm pitch and 4-position single-row crimp wire-to-board configuration
  • Mechanically compatible with standard 5.08 mm pitch X-keyed series header geometries
  • Uses Phoenix Contact CONNEXIS series crimp contacts rather than TE Dynamic contacts
  • Slight variation in locking latch enclosure geometry

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
