Substitute Part Grouping Explanation

Substitution between TSW-108-08-SS-S and TSW-108-08-S-S is determined by equivalence in the following critical parameters:

Manufacturer and series consistency (Samtec Inc., TSW series)
Identical connector type, contact type, and position configuration (Header, Male Pin, 8 positions, 1 row)
Matching pitch specification (0.100" / 2.54mm)
Identical mounting, termination, and fastening characteristics (Through Hole, Solder, Push-Pull)
Equivalent contact material, finish specifications, and insulation properties
Matching operating temperature range and flammability rating
Identical RoHS and MSL compliance status

The primary difference between these parts is packaging format: TSW-108-08-SS-S is supplied in Bulk packaging, while TSW-108-08-S-S is supplied in Bag packaging. This distinction does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Both TSW-108-08-SS-S and TSW-108-08-S-S are Active status products from Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts should be based on packaging requirements and inventory availability rather than electrical or mechanical performance, as all functional parameters are identical.

TSW-108-08-SS-S in Bulk packaging is suitable for high-volume production environments where component handling and storage systems accommodate bulk quantities. TSW-108-08-S-S in Bag packaging is appropriate for applications requiring smaller quantity management or where bag packaging integrates with existing component handling procedures.

Both parts satisfy identical compliance requirements including UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification, making them interchangeable from a regulatory and environmental standpoint.

Frequently Asked Questions (FAQ)

Q: Are TSW-108-08-SS-S and TSW-108-08-S-S electrically and mechanically interchangeable?

A: Yes. Both parts are identical in all electrical and mechanical specifications including connector type, position count, pitch, contact materials, finishes, and operating temperature range. The only difference is packaging format.

Q: What is the difference between Bulk and Bag packaging for these connectors?

A: Bulk packaging (TSW-108-08-SS-S) typically provides components in larger quantities without individual bag separation, suitable for automated assembly lines. Bag packaging (TSW-108-08-S-S) provides components in smaller grouped quantities within protective bags, suitable for manual assembly or smaller production runs.

Q: Can I substitute TSW-108-08-S-S for TSW-108-08-SS-S in an existing design?

A: Yes. Since all electrical, mechanical, and compliance parameters are identical, TSW-108-08-S-S can be directly substituted for TSW-108-08-SS-S without design modification or re-qualification.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-108-08-SS-S and TSW-108-08-S-S are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
