Parameter Comparison

Engineering Selection Recommendations

Both TSW-140-07-F-D and TSW-140-07-G-D are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent across all critical connector parameters including position count, pitch spacing, mounting configuration, and operating temperature range.

The primary differences between the two parts are limited to contact finish specifications. TSW-140-07-F-D features tin finish on the post with 3.00µin gold mating finish, while TSW-140-07-G-D features gold finish on both the post and mating surfaces with increased mating finish thickness of 10.0µin. Both configurations maintain compliance with applicable standards and certifications.

Selection between these parts should be based on inventory availability, lead time requirements, and specific application requirements related to contact finish durability and corrosion resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can TSW-140-07-G-D be used as a direct replacement for TSW-140-07-F-D?

A: Yes. Both parts maintain identical connector type, contact type, position count, row configuration, pitch spacing, mounting type, termination method, and fastening type. All critical electrical and mechanical parameters are equivalent.

Q: What are the differences between these two part numbers?

A: The primary differences are in contact finish specifications. TSW-140-07-F-D uses tin finish on the post with 3.00µin gold mating finish. TSW-140-07-G-D uses gold finish on both post and mating surfaces with 10.0µin mating finish thickness. Both parts are ROHS3 compliant and UL94 V-0 rated.

Q: Are there any compatibility issues with PCB layout or mating connectors?

A: No. Both parts share identical mechanical dimensions, pitch spacing, row spacing, contact length specifications, and insulation height. They are compatible with the same mating connectors and PCB layouts.

Q: Do both parts operate within the same temperature range?

A: Yes. Both TSW-140-07-F-D and TSW-140-07-G-D operate across the identical temperature range of -55°C to 125°C.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in bulk packaging as standard for this product category.

Q: What is the significance of the different contact finish specifications?

A: Contact finish thickness and material affect corrosion resistance and contact durability over extended operational life. The increased gold thickness on TSW-140-07-G-D (10.0µin versus 3.00µin) provides enhanced protection against oxidation and wear. Selection should be based on specific application environmental conditions and expected service life requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both TSW-140-07-F-D and TSW-140-07-G-D are ROHS3 compliant and carry identical EAR99 export classification and HTSUS commodity codes.
