Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-645501-3 terminal connector is determined by strict alignment of electrical and mechanical parameters. The critical substitution criteria are:

Pin Acceptance Specification: The substitute component must accept pin diameters within the range of 0.037" to 0.041" (0.94mm to 1.04mm). This parameter is non-negotiable for mechanical and electrical compatibility.

Termination Method: The substitute must utilize solder termination to maintain compatibility with existing PCB assembly processes and design specifications.

Series Classification: Both the original and substitute components belong to TE Connectivity AMP Connectors Series 4, ensuring consistency in connector family standards and mechanical interfaces.

Contact Material and Finish: The substitute should maintain beryllium copper contact material with tin finish to preserve electrical performance characteristics and corrosion resistance properties.

Board Thickness Compatibility: The substitute must accommodate board thicknesses of 0.031" to 0.125" (0.79mm to 3.18mm) to ensure proper installation on target PCBs.

The TE Connectivity AMP Connectors 5645501-3 meets all these substitution criteria and is classified as an active product with current manufacturing support.
