Substitute Part Grouping Explanation

Substitution of the 555139-2 is determined by strict equivalence across the following critical parameters: connector type (receptacle), position count (24), row configuration (2), mounting orientation (through hole, right angle), termination method (solder), connector style (outer shroud contacts), shielding requirement, contact finish material (gold), and flange specification (housing/shell 6-32). The substitute part 5555139-2 maintains identical electrical and mechanical specifications across all these parameters, differing only in product status (active versus obsolete), packaging format (tube), and regulatory compliance status (RoHS compliant and REACH affected versus non-compliant).
