Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSQ-125-21-G-S are identified based on strict equivalence of the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 25 positions
• Pitch & Mounting: 0.100" (2.54mm) mating pitch with through-hole solder termination
• Contact System: Forked gold-plated contacts with matching finish specifications
• Electrical Ratings: 465VAC / 655VDC voltage rating and -55°C to 125°C operating range
• Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Series Compatibility: SSQ series connectors with identical mechanical and electrical characteristics

The identified substitute part SSQ-125-01-G-S meets all these criteria and is sourced from the same manufacturer, ensuring design compatibility and interchangeability in applications requiring 25-position rectangular connectors with standard 0.1" pitch through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations
