Substitute Part Grouping Explanation

Substitution eligibility for the SSW-123-21-G-D is determined by strict alignment of the following critical parameters:

• Connector Type: Receptacle
• Number of Positions: 46
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Current Rating: 4.7A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part SSW-123-01-G-D meets all these criteria, confirming functional and mechanical equivalence for direct replacement applications.

Parameter Comparison

Both parts are ROHS3 compliant and carry identical electrical and mechanical specifications across all critical parameters. Selection between these parts may be based on inventory availability: SSW-123-21-G-D has 856 pieces in stock, while SSW-123-01-G-D has 719 pieces available. Both connectors satisfy UL94 V-0 flammability requirements and operate within the same temperature range, making either part suitable for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can SSW-123-01-G-D replace SSW-123-21-G-D in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch spacing, row configuration, mounting method, termination type, contact finish, current rating, operating temperature range, and flammability rating. Direct substitution is supported.

Q: Are there differences in contact geometry between these parts?

A: No. Both parts feature forked contacts with square shape, identical contact length (0.104"), and matching contact material (Phosphor Bronze) with equivalent gold plating thickness on both mating and post surfaces.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-123-21-G-D and SSW-123-01-G-D are ROHS3 compliant with UL94 V-0 flammability rating and EAR99 export classification.

Q: What is the difference between these part numbers?

A: The part numbers differ only in their suffix designation (21-G-D versus 01-G-D). All functional, electrical, and mechanical parameters remain identical, indicating these are equivalent variants within the SSW-123 base product family.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts operate across -55°C to 125°C and support 4.7A per contact with identical gold contact finish specifications.
