Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-122-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (22)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Contact finish (Gold)
• Voltage rating (465VAC, 655VDC minimum)
• Operating temperature range (-55°C ~ 125°C minimum)
• Series compatibility (SSQ)
• RoHS compliance status

The SSQ-122-01-G-S qualifies as a direct substitute based on identical specifications across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-122-21-G-S and SSQ-122-01-G-S are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and procurement lead times. The SSQ-122-01-G-S currently maintains higher inventory levels at 687 units compared to 650 units for the SSQ-122-21-G-S. Both parts meet UL94 V-0 flammability requirements and are suitable for applications requiring 465VAC or 655VDC voltage ratings across the -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are SSQ-122-21-G-S and SSQ-122-01-G-S fully interchangeable?

A: Yes. Both connectors share identical specifications for connector type, position count, pitch, mounting method, contact finish, voltage rating, temperature range, and material composition. They are direct substitutes within the SSQ series.

Q: What determines substitution eligibility for this connector category?

A: Substitution requires matching specifications across connector type (receptacle), position count (22), mating pitch (0.100"), mounting type (through hole), contact finish (gold), voltage rating (465VAC/655VDC minimum), and operating temperature range (-55°C to 125°C minimum).

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSQ-122-21-G-S and SSQ-122-01-G-S are ROHS3 compliant with UL94 V-0 flammability ratings and identical ECCN and HTSUS classifications.

Q: Are there any differences in contact specifications between these parts?

A: No. Both parts feature identical forked contact geometry, phosphor bronze material, gold plating thickness (20.0µin mating, 3.00µin post), and contact length specifications.

Q: What is the difference between the two part numbers?

A: The part numbers differ only in their suffix designation (21-G-S versus 01-G-S) within the same SSQ-122 base product family. All functional and electrical parameters are identical.
