Substitute Part Grouping Explanation

Substitution eligibility for the SSW-131-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (31)
• Mating pitch (0.100" / 2.54mm)
• Contact type (Forked)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish specification (Gold)
• Current rating (4.7A per contact)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• Insulation material (Liquid Crystal Polymer)
• Compliance status (ROHS3 Compliant)

The identified substitute part SSW-131-01-G-S meets all these criteria and belongs to the same SSW series base product family (SSW-131).

Parameter Comparison

Engineering Selection Recommendations
