TE Connectivity AMP 173977-4 2.0mm Pitch 4-Pin - Custom Wire Harness

  • Engineered with the TE Connectivity / AMP 173977-4 4-position single-row receptacle housing featuring an industry-standard 2.0mm (0.079") mating pitch, optimized for highly reliable, low-profile wire-to-board internal logic routing.
  • Utilizes the highly efficient AMP CT (Common Termination) Mass Termination (MT) IDC architecture, allowing unstripped discrete wires to be directly terminated into the tuning-fork contacts, significantly reducing assembly time and eliminating manual crimp-related defects.
  • Specifically calibrated for the precision mass termination of discrete wiring engineered for an operational wire gauge range of AWG #26 to AWG #28, ensuring robust signal transmission and reliable low-voltage power delivery (up to 2.0A maximum per pin).
  • Constructed from high-durability, glass-filled PBT (UL 94V-0 flammability rated) to maintain strict structural mating integrity and actively prevent housing deformation under broad industrial thermal cycling (-30°C to +105°C).
  • Features the shrouded, inherently polarized box-style housing geometry intrinsic to the TE CT series ecosystem, specifically designed to prevent contact damage during complex internal routing and guarantee secure mechanical retention in space-constrained enclosures.

What information do you need to provide a quote for a custom wire harness?

To provide an accurate quote and lead time, please provide:

  1. Technical Drawing or Diagram: Showing pinouts, lengths, and tolerances.
  2. Bill of Materials (BOM): Listing specific connectors (MPN) and wire gauges (AWG).
  3. Estimated Annual Usage (EAU): Helping us optimize pricing for your volume. Note: If you do not have a formal drawing, our engineering team can help create one based on your physical sample.
Can you suggest cost-saving alternatives for expensive connectors (e.g., TE, Molex, JST)?

Yes. We offer variety of alternative components.

We have extensive supply chain relationships in Taiwan and can suggest"Functionally Equivalent"alternatives that are fully compatible with major brands like TE, Molex, or JST but at a significantly lower cost. We will provide datasheets and samples of the alternative components for your approval before production.

How do you ensure quality control for custom cable assemblies?

Every single cable assembly undergoes rigorous testing before leaving our Taiwan facility. Our standard QC process includes:

  • 100% Continuity Testing: Ensuring no opens, shorts, or miswires.
  • Pull Force Testing: Verifying crimp strength.
  • Visual Inspection: Checking for cosmetic defects and label accuracy.
  • Hi-Pot Testing: Available upon request for high-voltage applications to ensure insulation integrity.
