Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-124-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 24 positions
• Pitch & Mounting: 0.100" (2.54mm) mating pitch with through-hole PCB mounting
• Contact System: Forked contact type with gold plating on mating surfaces
• Electrical Ratings: 465VAC / 655VDC voltage specification
• Temperature Range: -55°C to 125°C operating envelope
• Compliance: ROHS3 compliance and UL94 V-0 flammability rating
• Termination & Fastening: Solder termination with push-pull fastening mechanism

The SSQ-124-01-G-S meets all substitution criteria as it maintains identical electrical, mechanical, and environmental specifications while remaining within the same SSQ series family.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-124-21-G-S and SSQ-124-01-G-S are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are electrically and mechanically identical across all specified parameters. Selection between these two part numbers should be based on inventory availability and supply chain requirements. The SSQ-124-01-G-S currently maintains higher stock levels at 1140 units compared to 924 units for the SSQ-124-21-G-S, which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can SSQ-124-01-G-S be used as a direct replacement for SSQ-124-21-G-S?

A: Yes. Both parts are functionally equivalent across all electrical, mechanical, and environmental specifications. They share identical contact configurations, pitch, mounting type, and voltage ratings.

Q: Are there any PCB layout or footprint differences between these part numbers?

A: No. Both connectors maintain the same 0.100" (2.54mm) pitch, through-hole mounting pattern, and insulation height of 0.335" (8.51mm). PCB layouts are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSQ-124-21-G-S and SSQ-124-01-G-S are ROHS3 compliant and carry UL94 V-0 flammability certification. They are classified under the same ECCN (EAR99) and HTSUS codes.

Q: What is the difference between these two part numbers if they are equivalent?

A: The part numbers differ in their suffix designations (21-G-S versus 01-G-S), which may reflect internal Samtec manufacturing or distribution variants. All specified electrical and mechanical parameters remain identical.

Q: Are both parts suitable for -55°C to 125°C operating environments?

A: Yes. Both connectors are rated for the full -55°C to 125°C operating temperature range with identical contact materials and insulation specifications.
