Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 104656 is determined by strict equivalence across the following critical parameters:

Position Count & Configuration: The substitute must provide 154 total positions with identical signal-to-ground distribution (110 signal + 44 ground positions).

Pitch Specification: The connector pitch must be 0.079" (2.00mm) to ensure PCB footprint compatibility.

Termination Method: Press-fit termination is required to maintain assembly process compatibility and mechanical retention characteristics.

Connector Type & Polarity: Male pin header configuration must be preserved for mating surface compatibility.

Row Configuration: The 5+2 row arrangement must be maintained to ensure mechanical fit within the design envelope.

The substitute part 5188835-1 satisfies all these criteria and is manufactured by TE Connectivity AMP Connectors as an active product within the Z-PACK series.
