Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSW-108-21-S-S are identified within the SSW series based on matching the following critical parameters: 8-position configuration, 0.100" (2.54mm) mating pitch, receptacle connector type, forked contact design, through-hole mounting, gold mating contact finish, tin post finish, 4.7A per contact current rating, -55°C to 125°C operating temperature range, LCP insulation material, and UL94 V-0 flammability rating. All identified substitutes maintain identical electrical and mechanical specifications, differing only in fastening mechanism designation within the part number suffix.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SSW-108-21-S-S, SSW-108-01-S-S, and SSW-108-01-SM-S—are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is based on application requirements and inventory availability. SSW-108-21-S-S has 1044 units in stock, SSW-108-01-S-S has 1196 units in stock, and SSW-108-01-SM-S has 709 units in stock. All parts are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The choice among these substitutes does not affect electrical performance, thermal characteristics, or mechanical compatibility in applications requiring 8-position, 0.100" pitch receptacle connectors with gold mating contacts and tin-plated posts.

Frequently Asked Questions (FAQ)

Q: Can SSW-108-01-S-S and SSW-108-01-SM-S be used interchangeably with SSW-108-21-S-S?

A: Yes. All three parts share identical electrical and mechanical specifications, including connector type, position count, mating pitch, contact materials, current rating, and operating temperature range. They are direct substitutes within the SSW series.

Q: What determines compatibility between these substitute parts?

A: Compatibility is determined by matching specifications: 8-position receptacle configuration, 0.100" (2.54mm) mating pitch, forked contact design, through-hole mounting, gold mating contact finish, tin post finish, 4.7A per contact current rating, -55°C to 125°C operating temperature, LCP insulation material, and UL94 V-0 flammability rating.

Q: Are there differences in packaging or availability?

A: All parts are supplied in bulk packaging. Inventory levels differ: SSW-108-21-S-S (1044 pcs), SSW-108-01-S-S (1196 pcs), and SSW-108-01-SM-S (709 pcs).

Q: Do these parts meet RoHS and regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and carry UL94 V-0 material flammability certification, meeting standard regulatory requirements for industrial applications.

Q: What is the current rating for each contact?

A: Each contact is rated for 4.7A across all three substitute parts.
