Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSW-108-21-L-S is determined by strict equivalence across the following critical parameters:

• Connector Interface: 8-position receptacle with 0.100" (2.54mm) pitch mating interface
• Electrical Performance: 4.7A per contact current rating and -55°C to 125°C operating temperature range
• Contact Materials and Finishes: Gold-plated mating contacts (10.0µin thickness) and tin-plated posts
• Mechanical Configuration: Through-hole solder termination with push-pull fastening
• Insulation Specification: Liquid Crystal Polymer (LCP) with UL94 V-0 flammability rating
• Compliance: ROHS3 compliance and EAR99 export classification

The SSW-108-01-L-S meets all these criteria and is classified as a direct equivalent substitute.

Frequently Asked Questions (FAQ)

Q: Are SSW-108-21-L-S and SSW-108-01-L-S fully interchangeable?

A: Yes. Both parts are 8-position receptacle connectors with identical mating pitch (0.100"), contact finishes, current ratings (4.7A per contact), operating temperature range (-55°C to 125°C), and insulation materials (LCP). They are direct functional equivalents.

Q: What determines if a connector can substitute for the SSW-108-21-L-S?

A: Substitution requires matching on: connector type (receptacle), number of positions (8), mating pitch (0.100"), mounting method (through-hole), contact finish specifications (gold mating, tin post), current rating (4.7A per contact), operating temperature range (-55°C to 125°C), and insulation material (LCP with UL94 V-0 rating).

Q: Do these connectors have different mechanical footprints?

A: No. Both parts share identical insulation height (0.335"), contact length (0.104"), and all other mechanical dimensions. PCB layout and mounting hole patterns are identical.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts carry ROHS3 compliance, UL94 V-0 flammability rating, EAR99 export classification, and identical HTSUS codes (8536.69.4040).

Q: Can I use these connectors in high-temperature applications?

A: Yes. Both parts are rated for continuous operation from -55°C to 125°C, suitable for industrial and automotive temperature environments within this range.
