Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-140-24-G-D-LL is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Receptacle configuration within the SSQ series
• Position Count & Arrangement: 80 positions in 2-row configuration
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole mounting with press-fit/solder termination capability
• Contact Configuration: Forked contact type with gold mating finish
• Electrical Ratings: 465VAC / 655VDC voltage rating
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Temperature Range: -55°C to 125°C operating specification

The identified substitute part SSQ-140-04-G-D-LL maintains identical specifications across all critical parameters, differing only in the fastening type designation within the part number nomenclature while preserving functional equivalence.

Parameter Comparison
