Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-101-21-G-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (2)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Voltage rating (465VAC, 655VDC)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The substitute part SSQ-101-01-G-D meets all these criteria and belongs to the same SSQ series from Samtec Inc., confirming functional and mechanical interchangeability.
