Substitute Part Grouping Explanation

Substitution eligibility for the TSW-106-07-T-T-LL is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pin contacts
Position & Row Configuration: 18 positions arranged in 3 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
Material & Finish: Phosphor bronze contacts with tin finish on both mating and post surfaces
Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
Operating Range: -55°C to 105°C temperature specification

The HTSW-106-07-TM-T-LL qualifies as a substitute part because it maintains identical specifications across all critical electrical and mechanical parameters. Variations in insulation material (Liquid Crystal Polymer vs. Polybutylene Terephthalate) and insulation color do not affect functional compatibility or performance within the specified operating envelope.

Engineering Selection Recommendations

Both the TSW-106-07-T-T-LL and HTSW-106-07-TM-T-LL maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Inventory Availability: The HTSW-106-07-TM-T-LL currently maintains higher stock levels (925 pcs vs. 781 pcs), providing supply chain flexibility.

Insulation Material Considerations: The HTSW-106-07-TM-T-LL uses Liquid Crystal Polymer insulation, which offers superior dimensional stability and chemical resistance compared to the PBT insulation in the TSW-106-07-T-T-LL. Both materials meet the specified UL94 V-0 flammability requirement and operate across the identical -55°C to 105°C temperature range.

Visual Identification: The natural color insulation of the HTSW-106-07-TM-T-LL differs from the black insulation of the TSW-106-07-T-T-LL, which may affect assembly traceability or visual inspection protocols in manufacturing environments.

Both parts are electrically and mechanically interchangeable for applications requiring 18-position, 3-row, 0.100" pitch through-hole header connectors with tin-plated phosphor bronze contacts.

Frequently Asked Questions (FAQ)

Q: Are the TSW-106-07-T-T-LL and HTSW-106-07-TM-T-LL mechanically interchangeable?

A: Yes. Both parts share identical pitch (0.100"), row spacing (0.100"), contact geometry (square shape), and overall dimensions. They mount identically in through-hole PCB applications and accept the same mating connectors.

Q: What is the functional difference between PBT and LCP insulation materials?

A: Both materials meet UL94 V-0 flammability requirements and operate across -55°C to 105°C. Liquid Crystal Polymer (LCP) provides enhanced dimensional stability and chemical resistance, while Polybutylene Terephthalate (PBT) is a conventional engineering plastic. The choice depends on application-specific environmental exposure and dimensional tolerance requirements.

Q: Can I substitute the HTSW-106-07-TM-T-LL for the TSW-106-07-T-T-LL in existing designs?

A: Yes, provided your design does not specify insulation material or color as a critical requirement. All electrical and mechanical parameters are identical, including contact configuration, pitch, termination method, and operating temperature range.

Q: Do both parts require the same PCB footprint?

A: Yes. The identical pitch (0.100"), row spacing (0.100"), contact length specifications, and through-hole termination ensure both parts use the same PCB footprint and mounting pattern.

Q: Are both parts RoHS compliant?

A: Yes. Both the TSW-106-07-T-T-LL and HTSW-106-07-TM-T-LL are ROHS3 compliant with tin-plated contacts and phosphor bronze base material.
