Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-119-26-S-D is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 38 positions in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Operating Temperature Range: -55°C ~ 125°C
• Compliance Standards: ROHS3 Compliant, UL94 V-0 flammability rating

The substitute part HTSW-119-26-S-D meets all critical electrical and mechanical parameters required for direct substitution. Both parts share identical connector architecture, position configuration, pitch spacing, and thermal operating range. Variations in insulation material (PBT versus LCP) and insulation color do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both TSW-119-26-S-D and HTSW-119-26-S-D are active production parts manufactured by Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are electrically and mechanically interchangeable across all critical connector specifications.

Selection between these parts should be based on:

• Inventory Availability: HTSW-119-26-S-D currently has higher stock levels (971 units versus 669 units)
• Insulation Material Preference: TSW-119-26-S-D uses PBT insulation; HTSW-119-26-S-D uses LCP insulation. Both materials meet the specified operating temperature range and flammability requirements
• Supply Chain Requirements: Either part satisfies equivalent sourcing needs for through-hole header applications requiring 38-position, 2-row configuration with 2.54mm pitch spacing

Frequently Asked Questions (FAQ)

Q: Can HTSW-119-26-S-D be used as a direct replacement for TSW-119-26-S-D?

A: Yes. Both parts share identical connector type, position count, row configuration, pitch spacing, contact geometry, and operating temperature range. The parts are functionally equivalent for board-to-board and cable connection applications.

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

A: PBT (Polybutylene Terephthalate) and LCP (Liquid Crystal Polymer) are both thermoplastic insulation materials meeting UL94 V-0 flammability standards and the specified -55°C to 125°C operating temperature range. Material selection does not affect electrical performance or mechanical compatibility in standard applications.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-119-26-S-D and HTSW-119-26-S-D are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by matching connector type (header), contact type (male pin), position count (38), row count (2), mating pitch (0.100"), row spacing (0.100"), mounting type (through-hole), termination method (solder), and operating temperature range (-55°C to 125°C).

Q: Can these headers be used in high-temperature applications?

A: Both parts are rated for operating temperatures from -55°C to 125°C. Applications requiring temperatures outside this range require alternative connector solutions.
