Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-128-22-G-S is determined by strict equivalence across the following critical parameters:

Connector type (Receptacle)
Number of positions (28)
Mating pitch (0.100" / 2.54mm)
Contact type (Forked)
Mounting method (Through Hole)
Termination type (Solder)
Fastening mechanism (Push-Pull)
Contact finish specification (Gold)
Operating temperature range (-55°C ~ 125°C)
Voltage rating (465VAC, 655VDC)
Flammability compliance (UL94 V-0)
RoHS compliance status (ROHS3 Compliant)

The SSQ-128-02-G-S meets all these criteria and is classified as a direct equivalent part within the SSQ series.
