Substitute Part Grouping Explanation

The SSW-126-02-S-D-RA qualifies as a direct substitute for the SSW-126-22-S-D-RA based on identical electrical and mechanical parameters. Both parts share the same base product number (SSW-126) and maintain compatibility across all critical substitution criteria:

• 52-position receptacle configuration with identical pin count and arrangement
• 0.100" (2.54mm) pitch and row spacing for direct PCB footprint compatibility
• Through-hole, right-angle mounting orientation
• Gold-plated mating contacts with 30.0µin (0.76µm) thickness specification
• 4.7A per contact current rating
• -55°C to 125°C operating temperature range
• UL94 V-0 flammability rating
• ROHS3 compliance

The substitution is valid for applications requiring identical electrical performance and mechanical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-126-22-S-D-RA and SSW-126-02-S-D-RA are actively produced by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts should be based on inventory availability and procurement lead times, as they are electrically and mechanically identical. The SSW-126-02-S-D-RA currently maintains higher inventory (757 pcs) compared to the SSW-126-22-S-D-RA (684 pcs), which may influence procurement decisions for high-volume applications. Both parts meet UL94 V-0 flammability requirements and operate within identical temperature and current specifications.

Frequently Asked Questions (FAQ)

Q: Are SSW-126-22-S-D-RA and SSW-126-02-S-D-RA mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through-hole, right-angle), pitch (0.100"), row spacing (0.100"), and insulation height (0.195"). They mount to the same PCB footprint without modification.

Q: Do these connectors have the same electrical performance?

A: Yes. Both parts have identical current ratings (4.7A per contact), operating temperature range (-55°C to 125°C), contact finish specifications (gold mating, tin post), and contact material (phosphor bronze).

Q: What is the difference between SSW-126-22-S-D-RA and SSW-126-02-S-D-RA?

A: The parts are functionally identical. The difference in part number designation reflects manufacturing batch or internal Samtec classification, but all electrical and mechanical parameters are equivalent.

Q: Are both parts ROHS3 compliant?

A: Yes. Both SSW-126-22-S-D-RA and SSW-126-02-S-D-RA are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: Can I use SSW-126-02-S-D-RA as a direct replacement in existing designs?

A: Yes. No design modifications are required. The connector maintains identical pin count, spacing, mounting orientation, and electrical specifications.
