Substitute Part Grouping Explanation

Substitution eligibility for the TSW-108-24-S-D-LL is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Configuration: 16 positions in 2 rows
Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole mounting with kinked pin solder termination
Electrical & Environmental Compliance: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability rating, RoHS3 compliance

The substitute part HTSW-108-24-S-D-LL meets all critical substitution criteria. Variations in insulation material (PBT vs. LCP) and insulation color do not affect functional compatibility in applications where the connector's primary electrical and mechanical interface requirements are met.

Engineering Selection Recommendations

Both the TSW-108-24-S-D-LL and HTSW-108-24-S-D-LL are active production parts manufactured by Samtec Inc. and meet identical electrical, mechanical, and compliance requirements for 16-position 0.100" (2.54mm) pitch header connector applications.

Selection between these parts is based on:

Insulation Material Requirements: PBT insulation (TSW-108-24-S-D-LL) or LCP insulation (HTSW-108-24-S-D-LL) based on application thermal and chemical resistance specifications
Moisture Sensitivity Handling: TSW-108-24-S-D-LL carries MSL 1 rating; HTSW-108-24-S-D-LL is not applicable for MSL considerations
Inventory Availability: HTSW-108-24-S-D-LL has 1096 units in stock; TSW-108-24-S-D-LL has 685 units in stock
Compliance Verification: Both parts are RoHS3 compliant and carry active product status

Frequently Asked Questions (FAQ)

Q: Can HTSW-108-24-S-D-LL be used as a direct replacement for TSW-108-24-S-D-LL?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (16), row configuration (2 rows), contact geometry, termination method, and operating temperature range. The connectors are mechanically and electrically interchangeable in applications where the specified insulation material and moisture sensitivity characteristics are compatible.

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 insulation materials meeting UL94 V-0 flammability requirements. Material selection depends on application-specific requirements for thermal stability, chemical resistance, and dimensional stability. Consult material datasheets for specific environmental exposure conditions.

Q: Are both parts suitable for high-temperature applications?

A: Both connectors operate across -55°C to 125°C. This temperature range applies to the connector body and contact assembly. Verify that mating components, PCB materials, and solder joint specifications support this temperature range for the complete assembly.

Q: What does MSL 1 (Unlimited) mean for the TSW-108-24-S-D-LL?

A: MSL 1 indicates the part has unlimited shelf life and does not require moisture-controlled storage or baking procedures prior to soldering. The HTSW-108-24-S-D-LL is marked as Not Applicable for MSL, indicating it does not fall under standard MSL classifications.

Q: Can these connectors be used in board-to-board or cable applications?

A: Yes. Both connectors are specified for Board to Board or Cable style applications. Ensure mating connectors and cable assemblies are compatible with the 0.100" (2.54mm) pitch and 16-position configuration.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TSW-108-24-S-D-LL and HTSW-108-24-S-D-LL are RoHS3 compliant, meeting restrictions on hazardous substances in electrical and electronic equipment.
