Engineering Selection Recommendations

All three parts—TSW-104-07-SS-S, TSW-104-07-S-S, and HTSW-104-07-SM-S—are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection among these parts is based on the following factors:

TSW-104-07-SS-S and TSW-104-07-S-S: Both utilize PBT insulation material and are functionally equivalent. The primary distinction is inventory availability, with TSW-104-07-S-S offering higher stock levels (3205 pcs vs. 1001 pcs). Both maintain identical electrical and mechanical specifications.

HTSW-104-07-SM-S: This part substitutes LCP insulation material for PBT and carries a Not Applicable MSL designation rather than MSL 1. The HTSW series represents an alternative design within the same connector family. All three parts satisfy the same operating temperature range, contact material specifications, and flammability requirements.

Selection should prioritize part availability and supply chain requirements while maintaining design consistency within the connector family.

Frequently Asked Questions (FAQ)

Q: Can TSW-104-07-S-S be used as a direct replacement for TSW-104-07-SS-S?

A: Yes. Both parts share identical electrical and mechanical specifications, including pitch (0.100" / 2.54mm), number of positions (4), contact material (Phosphor Bronze), contact finish (Gold mating / Tin post), operating temperature range (-55°C ~ 125°C), and flammability rating (UL94 V-0). Both are ROHS3 compliant and utilize PBT insulation.

Q: What is the difference between the TSW and HTSW series?

A: The primary difference is insulation material. TSW series parts use Polybutylene Terephthalate (PBT), while HTSW series parts use Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements and maintain identical contact specifications and operating temperature ranges. The HTSW series carries a Not Applicable MSL designation.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts maintain identical pitch (0.100" / 2.54mm), number of positions (4), contact length specifications, and through-hole mounting requirements. PCB footprints are compatible across all three parts.

Q: Do these connectors require any special handling or storage considerations?

A: TSW-104-07-SS-S and TSW-104-07-S-S carry MSL 1 (Unlimited) designation, indicating no moisture sensitivity restrictions. HTSW-104-07-SM-S carries Not Applicable MSL designation. Standard component storage practices apply to all three parts.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant. Material flammability rating is UL94 V-0 for all parts. ECCN classification is EAR99 for all parts. HTSUS code is 8536.69.4040 for all parts.
