Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 063387 is based on the following critical parameters that must align between the main part and substitute components:

Position Count: Both the main part and substitute must support 25 positions to maintain connector density and pin assignment compatibility.

D-Sub Connector Family: The substitute must be classified within the D-Sub, D-Shaped Connectors category to ensure mechanical and electrical compatibility with existing D-Sub infrastructure.

Shell Size Compatibility: The substitute must support Shell Size B to ensure proper mating with existing connector housings and cable assemblies.

Shielding Requirement: The substitute must provide shielded construction to maintain electromagnetic interference protection equivalent to the original design.

Hardware Specification: The substitute must incorporate 4-40 mating screws to ensure mechanical fastening compatibility with existing backshell assemblies.

Regulatory Compliance: The substitute must maintain RoHS compliance and REACH status to satisfy current manufacturing and environmental regulations.

The TE Connectivity AMP Connectors part number 1-747947-5 satisfies these substitution criteria as an active product within the D-Sub connector family with equivalent position count, shell size, shielding, and hardware specifications.

Parameter Comparison
