Substitute Part Grouping Explanation

The SSW-120-03-G-D-RA qualifies as a substitute for the SSW-120-23-G-D-RA based on the following critical parameters that determine functional interchangeability:

• Connector Type & Configuration: Both are 40-position receptacle connectors with identical pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
• Mounting & Termination: Both feature through-hole, right-angle mounting with solder termination
• Contact Specifications: Identical forked contact type, square contact shape, phosphor bronze material, and gold plating on mating surfaces
• Electrical Performance: Both rated at 4.7A per contact with identical contact finish thickness on mating surfaces (20.0µin / 0.51µm)
• Environmental & Compliance: Both operate across -55°C to 125°C, maintain UL94 V-0 flammability rating, and are ROHS3 compliant
• Series & Base Product: Both belong to the SSW series with identical base product number SSW-120

The substitution is valid across all critical mechanical and electrical parameters. Differences in MSL rating and inventory levels do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-120-23-G-D-RA and SSW-120-03-G-D-RA are suitable for equivalent applications based on their identical electrical, mechanical, and compliance specifications. Selection between these parts should be based on:

• Product Availability: Both parts maintain Active status with established supply channels through Samtec Inc.
• Regulatory Compliance: Both meet ROHS3 requirements and carry identical ECCN and HTSUS classifications, ensuring compliance across regulated markets.
• Environmental Certification: Both achieve UL94 V-0 flammability rating, supporting applications requiring flame-resistance certification.
• Inventory Considerations: The SSW-120-03-G-D-RA currently maintains higher inventory (1353 Pcs) compared to SSW-120-23-G-D-RA (792 Pcs), which may influence procurement decisions for high-volume production.

Frequently Asked Questions (FAQ)

Q: Are SSW-120-23-G-D-RA and SSW-120-03-G-D-RA mechanically interchangeable?

A: Yes. Both connectors feature identical 40-position configuration, 0.100" (2.54mm) pitch, 2-row layout, through-hole right-angle mounting, and forked contact geometry. They are mechanically interchangeable in board designs.

Q: Can these parts be used interchangeably in high-current applications?

A: Yes. Both parts are rated at 4.7A per contact with identical contact materials (phosphor bronze) and gold plating specifications. Electrical performance is equivalent across the rated operating range.

Q: What is the difference between the part numbers SSW-120-23-G-D-RA and SSW-120-03-G-D-RA?

A: The numeric designations (23 vs. 03) represent internal Samtec manufacturing variants. All critical electrical, mechanical, and compliance parameters are identical, making them functionally equivalent for design and procurement purposes.

Q: Are both parts suitable for temperature-sensitive applications?

A: Yes. Both connectors operate across -55°C to 125°C with identical material specifications (Liquid Crystal Polymer insulation, UL94 V-0 rating), supporting applications across this full temperature range.

Q: Do these connectors meet RoHS requirements?

A: Yes. Both SSW-120-23-G-D-RA and SSW-120-03-G-D-RA are ROHS3 compliant, meeting European Union Restriction of Hazardous Substances directives.

Q: Can I substitute one part for the other in existing production?

A: Yes. The parts are functionally equivalent across all specified parameters. Substitution does not require design modification or re-qualification when both parts are sourced from Samtec Inc. and maintain identical specifications.
