Substitute Part Grouping Explanation

Substitute parts for the TSW-103-17-S-D are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

Connector Type: Header
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 6
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole
Termination: Solder
Contact Finish - Mating: Gold
Operating Temperature Range: -55°C ~ 125°C
Material Flammability Rating: UL94 V-0

Engineering Selection Recommendations

Both the TSW-103-17-S-D and HTSW-103-17-S-D are active production parts manufactured by Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Product Availability: Both parts maintain active inventory status. The TSW-103-17-S-D has 981 pieces in stock, while the HTSW-103-17-S-D has 928 pieces available.

Material Specification: The primary difference is insulation material composition. The TSW-103-17-S-D uses PBT (Polybutylene Terephthalate), while the HTSW-103-17-S-D uses LCP (Liquid Crystal Polymer). Both materials meet the same flammability and temperature specifications. Material selection should align with specific application environmental conditions and design requirements.

Regulatory Compliance: Both parts carry identical regulatory certifications (ROHS3, EAR99, HTSUS 8536.69.4040), ensuring compliance with applicable standards.

Frequently Asked Questions (FAQ)

Q: Are the TSW-103-17-S-D and HTSW-103-17-S-D mechanically interchangeable?

A: Yes. Both parts share identical pitch spacing (0.100"), position count (6), row configuration (2 rows), contact geometry, and mounting specifications. They are mechanically interchangeable in through-hole PCB applications.

Q: What is the functional difference between PBT and LCP insulation materials in these connectors?

A: Both PBT and LCP meet the same operating temperature range (-55°C ~ 125°C) and UL94 V-0 flammability rating. The choice between materials depends on specific application requirements such as chemical resistance, dimensional stability, or environmental exposure conditions.

Q: Can I substitute the HTSW-103-17-S-D for the TSW-103-17-S-D in an existing design?

A: Substitution is valid when all electrical and mechanical parameters remain compatible. Since both parts maintain identical contact specifications, pitch, position count, and operating temperature range, substitution is electrically and mechanically sound. Verify material compatibility with your specific application environment.

Q: Are there any differences in moisture sensitivity between these parts?

A: The TSW-103-17-S-D has a Moisture Sensitivity Level (MSL) of 1 (Unlimited). The HTSW-103-17-S-D is listed as Not Applicable for MSL. Both parts are suitable for standard storage and handling conditions without special moisture control requirements.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the TSW-103-17-S-D and HTSW-103-17-S-D are ROHS3 compliant, meeting current regulatory requirements for restricted substance elimination.
