Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-127-24-G-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle, board-to-board or cable configuration
• Contact Configuration: 54 positions, 2 rows, forked contact type
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Electrical & Environmental Ratings: 465VAC / 655VDC voltage rating, -55°C to 125°C operating temperature
• Termination & Mounting: Solder termination, through-hole mounting, push-pull fastening
• Surface Finish: Gold-plated mating contacts
• Compliance: UL94 V-0 flammability rating, ROHS3 compliance

The substitute part SSQ-127-04-G-D meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

• Compliance Status: Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification
• Lead Time Requirements: Both are active products with established supply chains
• Application Continuity: Direct substitution is supported without design modification

Frequently Asked Questions (FAQ)

Q: Can SSQ-127-04-G-D be used as a direct replacement for SSQ-127-24-G-D?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical contact configurations, pitch specifications, voltage ratings, temperature ranges, and compliance certifications. No circuit or PCB layout modifications are required.

Q: What determines substitution eligibility for SSQ series connectors?

A: Substitution is valid when parts maintain identical specifications across connector type, position count, row configuration, pitch, mounting method, termination type, fastening mechanism, contact finish, and electrical ratings. The SSQ-127-24-G-D and SSQ-127-04-G-D meet all these criteria.

Q: Are there any packaging or handling differences between these parts?

A: Both parts are supplied in bulk packaging. No differences in moisture sensitivity level, storage requirements, or handling procedures apply.

Q: What is the difference between the part numbers SSQ-127-24-G-D and SSQ-127-04-G-D?

A: The base product number is SSQ-127 for both parts. The numeric designations (24 and 04) represent internal Samtec manufacturing variants that do not affect electrical or mechanical performance. Both variants are functionally identical for end-use applications.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the -55°C to 125°C temperature range and carry UL94 V-0 flammability certification, making them suitable for industrial and demanding thermal environments.
