Substitute Part Grouping Explanation

Substitute parts for the TSW-105-24-S-D-LL are identified based on strict electrical and mechanical parameter equivalence. The critical parameters determining substitutability are:

Connector type (Header)
Contact type (Male Pin)
Number of positions and rows (10 positions, 2 rows)
Pitch spacing (0.100" / 2.54mm mating pitch and row spacing)
Mounting method (Through Hole)
Termination style (Kinked Pin, Solder)
Contact finish on mating surface (Gold)
Contact material (Phosphor Bronze)
Operating temperature range (-55°C ~ 125°C)
Flammability rating (UL94 V-0)
RoHS compliance (ROHS3 Compliant)

The HTSW-105-24-S-D-LL meets all these core requirements and qualifies as a direct substitute. Minor variations in insulation material (LCP versus PBT) and MSL classification do not affect functional compatibility in standard applications.

Engineering Selection Recommendations

Both the TSW-105-24-S-D-LL and HTSW-105-24-S-D-LL are active products from Samtec Inc. with identical electrical and mechanical specifications for mating interfaces, contact geometry, and termination characteristics. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

The primary distinction lies in insulation material composition: the TSW series uses PBT while the HTSW series uses LCP. Both materials satisfy the operating temperature range of -55°C to 125°C and provide equivalent mechanical performance in standard through-hole PCB applications. Selection between these parts should be based on inventory availability, supply chain considerations, and any application-specific material requirements documented in design specifications.

Frequently Asked Questions (FAQ)

Q: Can HTSW-105-24-S-D-LL be used as a direct replacement for TSW-105-24-S-D-LL?

A: Yes. Both connectors share identical pitch spacing (0.100" / 2.54mm), position count (10 positions in 2 rows), contact geometry, mating surface finish (gold-plated phosphor bronze), and operating temperature range (-55°C to 125°C). The connectors are mechanically and electrically interchangeable in standard applications.

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

A: PBT (Polybutylene Terephthalate) and LCP (Liquid Crystal Polymer) are both thermoplastic materials suitable for connector insulation. Both materials meet UL94 V-0 flammability requirements and operate across the specified temperature range. Material selection typically depends on specific environmental or mechanical requirements not detailed in standard connector specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-105-24-S-D-LL and HTSW-105-24-S-D-LL are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What is the moisture sensitivity level (MSL) difference between these parts?

A: The TSW-105-24-S-D-LL carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The HTSW-105-24-S-D-LL is listed as Not Applicable for MSL. Both classifications indicate minimal or no moisture-related handling constraints for standard storage and assembly processes.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes. The identical pitch spacing, row configuration, contact length, and mounting type ensure mechanical compatibility with existing PCB footprints designed for either part number.
