Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-118-22-F-D-RA is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle, 36-position, 2-row layout
• Pitch & Spacing: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole, right-angle orientation with 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 Finishes: Gold plating on mating contacts (3.00µin thickness), tin plating on posts

The substitute part SSW-118-02-F-D-RA meets all these criteria, confirming full mechanical and electrical interchangeability for applications requiring the SSW-118-22-F-D-RA specification.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-118-22-F-D-RA and SSW-118-02-F-D-RA are active products from Samtec Inc. with identical electrical, mechanical, and environmental specifications. Selection between these parts should be based on:

Availability: The SSW-118-22-F-D-RA maintains 1033 pieces in stock, while the SSW-118-02-F-D-RA has 977 pieces available. Either part satisfies supply requirements for standard production volumes.

Compliance: Both connectors meet ROHS3 compliance and UL94 V-0 flammability standards, suitable for regulated applications in industrial, telecommunications, and commercial equipment sectors.

Interchangeability: Full mechanical and electrical interchangeability is confirmed across all specified parameters. PCB layout, mating interface, and solder joint requirements remain identical between parts.

Cost Optimization: When primary part allocation is constrained, the substitute part provides equivalent performance without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can SSW-118-02-F-D-RA be used as a direct replacement for SSW-118-22-F-D-RA?

A: Yes. Both parts are identical in connector type, position count, pitch spacing, mounting orientation, contact configuration, and electrical ratings. No PCB redesign or interface modification is required.

Q: Are the mating interfaces compatible between these two part numbers?

A: Yes. Both connectors feature 36-position, 2-row receptacle configuration with 0.100" (2.54mm) pitch and row spacing. Mating plugs and cable assemblies designed for one part are fully compatible with the other.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the SSW-118-22-F-D-RA and SSW-118-02-F-D-RA are ROHS3 compliant, rated UL94 V-0 for flammability, and operate across -55°C to 125°C. Regulatory and environmental requirements are identical.

Q: What is the difference between these two part numbers if all specifications match?

A: The provided data indicates both parts are functionally equivalent. Differences in part numbering may reflect manufacturing lot designation, internal Samtec inventory management, or historical product line organization. No technical differentiation exists based on the specified parameters.

Q: Can I mix these connectors in the same assembly?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably within the same assembly or across multiple production batches without performance degradation or compatibility issues.

Q: What current capacity should I design for when using either connector?

A: Both connectors are rated for 4.7A per contact. Total assembly current capacity depends on the number of loaded positions and circuit design. Ensure PCB trace sizing and power distribution accommodate this per-contact rating.
