Substitute Part Grouping Explanation

Substitution eligibility for the SSW-110-22-F-D-RA-LL is determined by strict equivalence across the following critical parameters:

Connector Type & Configuration: Receptacle, 20-position, 2-row layout
Pitch & Spacing: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole, right-angle mounting with kinked pin solder termination
Contact Specifications: Forked contact type, square contact shape, phosphor bronze material
Electrical Performance: 4.7A per contact current rating
Environmental Compliance: Operating temperature range -55°C to 125°C, UL94 V-0 flammability rating, ROHS3 compliance
Contact Finish: Gold mating surface (3.00µin thickness), tin post finish

The substitute part SSW-110-02-F-D-RA-LL meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Engineering Selection Recommendations

Both the SSW-110-22-F-D-RA-LL and SSW-110-02-F-D-RA-LL maintain active product status from Samtec Inc. and carry identical electrical, mechanical, and environmental specifications. Selection between these parts should be based on inventory availability and procurement lead times. The SSW-110-02-F-D-RA-LL currently maintains higher inventory (911 pcs) compared to the SSW-110-22-F-D-RA-LL (862 pcs), both available as new original stock. Both parts satisfy ROHS3 compliance requirements and UL94 V-0 flammability standards, making either suitable for applications requiring regulatory compliance in industrial and commercial environments.

Frequently Asked Questions (FAQ)

Q: Are SSW-110-22-F-D-RA-LL and SSW-110-02-F-D-RA-LL electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications including 4.7A per contact current rating, operating temperature range of -55°C to 125°C, and contact finish specifications (gold mating, tin post). They are electrically equivalent.

Q: Are these connectors mechanically interchangeable?

A: Yes. Both connectors feature identical mechanical specifications: 20-position, 2-row configuration with 0.100" (2.54mm) pitch and row spacing, through-hole right-angle mounting, forked contact type, and square contact geometry. They are mechanically equivalent.

Q: What determines substitution eligibility for this connector family?

A: Substitution is determined by matching connector type (receptacle), position count (20), row configuration (2), mating pitch (0.100"), row spacing (0.100"), mounting style (through-hole right-angle), contact type (forked), contact material (phosphor bronze), contact finish (gold mating/tin post), current rating (4.7A), operating temperature range (-55°C to 125°C), and compliance certifications (UL94 V-0, ROHS3).

Q: Can I use these connectors in applications requiring different operating temperatures?

A: No. Both parts are rated for -55°C to 125°C operation. Applications requiring different temperature ranges require alternative connector models.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-110-22-F-D-RA-LL and SSW-110-02-F-D-RA-LL are ROHS3 compliant.

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

A: Based on provided specifications, both parts are identical across all electrical, mechanical, and environmental parameters. The part number variation reflects Samtec's internal product designation system but does not indicate functional differences.
