Substitute Part Grouping Explanation

The SSQ-125-22-S-T-RA qualifies as a direct substitute for the SSQ-125-02-S-T-RA based on the following critical parameters:

• Connector Type & Configuration: Both are 75-position receptacle connectors with identical pitch (0.100"), row count (3), and row spacing (0.100")
• Mounting & Termination: Both feature through-hole right-angle mounting with solder termination
• Electrical Specifications: Both maintain identical voltage ratings (465VAC, 655VDC) and operating temperature range (-55°C ~ 125°C)
• Contact Properties: Both utilize gold-plated mating contacts with 30.0µin (0.76µm) thickness and tin-plated posts
• Material & Compliance: Both are constructed from Liquid Crystal Polymer (LCP) insulation, rated UL94 V-0, and are ROHS3 compliant
• Series Consistency: Both belong to the SSQ series with identical base product number (SSQ-125)

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-125-02-S-T-RA and SSQ-125-22-S-T-RA are active production parts with full ROHS3 compliance and UL94 V-0 material certification. Selection between these parts should be based on inventory availability and procurement timelines. The SSQ-125-02-S-T-RA currently maintains higher stock levels (1003 units) compared to the SSQ-125-22-S-T-RA (932 units). Both parts meet identical electrical, mechanical, and environmental specifications and are suitable for direct substitution in board-to-board and cable connector applications requiring 75-position, 0.100" pitch rectangular connectors.
