Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSQ-122-21-S-D are identified based on the following critical parameters that determine functional equivalence:

• Connector Type & Position Count: Receptacle configuration with 44 positions
• Pitch & Row Spacing: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Contact Interface: Gold-plated mating contacts with 30.0µin (0.76µm) thickness
• Electrical Ratings: 465VAC / 655VDC voltage rating
• Temperature Range: -55°C to 125°C operating specification
• Material Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The SSQ-122-01-S-D meets all these criteria and is classified as a direct substitute. Both parts share identical mechanical interfaces, electrical performance characteristics, and regulatory compliance certifications within the SSQ series.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-122-21-S-D and SSQ-122-01-S-D are active products with full regulatory compliance. Selection between these parts should be based on inventory availability and procurement lead times. The SSQ-122-21-S-D currently maintains 1024 units in stock, while the SSQ-122-01-S-D maintains 767 units. Both parts carry ROHS3 compliance certification and UL94 V-0 flammability rating, meeting equivalent environmental and safety standards. The SSQ-122-01-S-D additionally carries REACH Unaffected status. For applications requiring immediate availability, the SSQ-122-21-S-D is the preferred selection. For applications with flexible scheduling, either part provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can SSQ-122-01-S-D be used as a direct replacement for SSQ-122-21-S-D?

A: Yes. Both connectors share identical specifications across all critical parameters: 44-position receptacle configuration, 0.100" (2.54mm) pitch, through-hole solder termination, gold-plated contacts, and 465VAC / 655VDC voltage rating. Mechanical and electrical compatibility is complete.

Q: Are there differences in contact durability or mating cycles between these parts?

A: No contact durability or mating cycle specifications are provided in the technical data for either part. Both use identical contact materials (phosphor bronze) and finishes (gold mating, tin post).

Q: What is the difference between the SSQ-122-21-S-D and SSQ-122-01-S-D part numbers?

A: The part numbers differ in the position designator (21 versus 01), but all provided electrical, mechanical, and material specifications are identical. Both are members of the SSQ series and share the same base product number SSQ-122.

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, meeting requirements for industrial and high-reliability applications.

Q: What is the significance of the gold contact finish thickness specification?

A: The 30.0µin (0.76µm) gold plating thickness on mating contacts ensures consistent contact resistance and corrosion protection across the connector's operational life. Both parts meet this specification identically.

Q: Can these connectors be used in applications requiring REACH compliance?

A: The SSQ-122-01-S-D carries explicit REACH Unaffected status. The SSQ-122-21-S-D does not list REACH status in the provided data. For applications with REACH compliance requirements, the SSQ-122-01-S-D is the documented choice.
