Substitute Part Grouping Explanation

Substitution eligibility for the TSW-105-24-L-D-LL is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Configuration: 10 positions arranged in 2 rows
Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole mounting with kinked pin solder termination
Contact Geometry: Square contact shape with specified mating and post lengths
Contact Material & Finish: Phosphor bronze with gold mating finish and tin post finish
Operating Environment: Temperature range -55°C to 125°C
Compliance: ROHS3 compliance and UL94 V-0 flammability rating

The HTSW-105-24-L-D-LL meets all critical substitution criteria with one material variation in the insulation substrate.

Engineering Selection Recommendations

Both the TSW-105-24-L-D-LL and HTSW-105-24-L-D-LL are active products from Samtec Inc. with identical electrical and mechanical specifications. Both connectors maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

The primary distinction between these parts is the insulation material composition: the TSW series uses Polybutylene Terephthalate (PBT), while the HTSW series uses Liquid Crystal Polymer (LCP). Both materials support the specified operating temperature range and maintain equivalent mechanical performance within the defined parameters.

Selection between these parts should be based on material availability, inventory status, and any application-specific material requirements not specified in the provided parameters.

Frequently Asked Questions (FAQ)

Q: Are TSW-105-24-L-D-LL and HTSW-105-24-L-D-LL mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (10), row configuration (2 rows), contact geometry, and mounting specifications. They are mechanically interchangeable in through-hole PCB applications.

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

A: The TSW-105-24-L-D-LL uses PBT insulation, while the HTSW-105-24-L-D-LL uses LCP insulation. Both materials meet the specified operating temperature range (-55°C to 125°C) and UL94 V-0 flammability rating. Material selection depends on application-specific requirements not detailed in the provided specifications.

Q: Can I use HTSW-105-24-L-D-LL as a direct replacement for TSW-105-24-L-D-LL?

A: Yes, the HTSW-105-24-L-D-LL qualifies as a substitute part based on matching electrical, mechanical, and compliance specifications. Both parts are ROHS3 compliant and carry identical regulatory classifications.
