Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-101-26-L-D is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 2 positions, 2 rows
• Pitch & Spacing: 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull fastening
• Operating Temperature Range: -55°C ~ 125°C
• Flammability & Compliance: UL94 V-0, ROHS3 Compliant

The HTSW-101-26-L-D qualifies as a substitute part because it maintains identical specifications across all critical electrical and mechanical parameters. Differences in insulation material (Liquid Crystal Polymer vs. Polybutylene Terephthalate) and insulation color do not affect functional compatibility in standard applications, as both materials meet the same flammability and thermal requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-101-26-L-D and HTSW-101-26-L-D are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. The HTSW-101-26-L-D serves as a direct functional substitute, maintaining all critical electrical and mechanical specifications required for board-to-board or cable connector applications.

The primary distinction between these parts lies in insulation material composition. The TSW series uses Polybutylene Terephthalate (PBT), while the HTSW series uses Liquid Crystal Polymer (LCP). Both materials satisfy the same thermal operating range (-55°C ~ 125°C) and flammability requirements. Selection between these variants should be based on application-specific material requirements, environmental exposure conditions, or inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the HTSW-101-26-L-D be used as a direct replacement for the TSW-101-26-L-D?

A: Yes. Both connectors share identical electrical and mechanical specifications, including contact configuration, pitch, mounting type, termination method, and operating temperature range. The difference in insulation material (LCP vs. PBT) does not affect functional compatibility in standard applications.

Q: What is the significance of the insulation material difference between TSW and HTSW series?

A: Polybutylene Terephthalate (PBT) and Liquid Crystal Polymer (LCP) are both high-performance thermoplastic materials meeting UL94 V-0 flammability standards and the same thermal operating range. Material selection depends on specific application requirements such as chemical resistance, dimensional stability, or environmental exposure. Both materials are suitable for the specified operating conditions.

Q: Are there any compatibility concerns with PCB footprints or mating connectors?

A: No. The TSW-101-26-L-D and HTSW-101-26-L-D maintain identical physical dimensions, contact spacing (0.100" / 2.54mm), and mounting hole patterns. Existing PCB designs and mating connectors are fully compatible with either part.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: The TSW-101-26-L-D is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The HTSW-101-26-L-D is listed as Not Applicable, which reflects the material properties of LCP. Both parts are suitable for standard storage and handling conditions without special moisture control requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the TSW-101-26-L-D and HTSW-101-26-L-D are ROHS3 compliant, meeting all applicable restrictions on hazardous substances.
