Substitute Part Grouping Explanation
Substitution of the TE Connectivity Erni 043138 is determined by strict equivalence across the following critical parameters:
Position and Pitch Compatibility: The substitute part must maintain identical 55-position configuration with 0.079" (2.00mm) pitch spacing to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.
Connector Architecture: Both the main part and substitute must feature identical connector type (Header, Male Pins), connector style (C 11), and row configuration (5 rows) to guarantee physical interchangeability.
Termination and Mounting: Press-fit termination through through-hole mounting is mandatory for both components to maintain assembly process compatibility and board integration requirements.
Environmental and Compliance Specifications: Operating temperature range of -55°C ~ 125°C, gold contact finish, board guide feature, and RoHS compliance status must be maintained across substitution.
The TE Connectivity AMP Connectors 5188232-1 satisfies all substitution criteria as an active product with identical mechanical and electrical parameters.
