Key Parameters

Substitute Part Grouping Explanation

The SSQ-128-03-G-S qualifies as a direct substitute for the SSQ-128-23-G-S based on the following critical parameters:

• Connector Type & Position Count: Both are 28-position receptacle connectors within the SSQ series
• Pitch & Mounting: Identical 0.100" (2.54mm) mating pitch and through-hole mounting configuration
• Contact Specifications: Both feature forked contacts with gold plating (20.0µin mating finish) and phosphor bronze material
• Electrical Ratings: Matching voltage ratings of 465VAC and 655VDC
• Temperature Range: Identical operating temperature range of -55°C to 125°C
• Compliance: Both are ROHS3 compliant with UL94 V-0 flammability rating
• Insulation Material: Both use Liquid Crystal Polymer (LCP) insulation in black color

The substitution is based on functional equivalence across all provided electrical and mechanical parameters.
