Substitute Part Grouping Explanation

Substitution eligibility for the TSW-108-07-SS-D-LL is determined by strict alignment of 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 kinked pin solder termination
Operating Temperature Range: -55°C to 125°C
Compliance: ROHS3 compliance and UL94 V-0 flammability rating
Contact Materials & Finishes: Phosphor bronze with gold mating finish (30.0µin) and tin post finish
Mechanical Dimensions: Contact lengths, insulation height, and overall geometry

Substitute parts must maintain identical values across all these parameters. Variations in insulation material (PBT vs. LCP) and moisture sensitivity level do not affect electrical or mechanical compatibility when all other specifications remain constant.

Engineering Selection Recommendations

All three parts—TSW-108-07-SS-D-LL, TSW-108-07-S-D-LL, and HTSW-108-07-S-D-LL—maintain active product status and full ROHS3 compliance. Selection between these parts should be based on insulation material requirements and series preference:

TSW-108-07-SS-D-LL and TSW-108-07-S-D-LL both utilize polybutylene terephthalate (PBT) insulation and belong to the TSW series. These parts are functionally equivalent and differ only in minor design variations. Both support unlimited moisture sensitivity (MSL 1).

HTSW-108-07-S-D-LL employs liquid crystal polymer (LCP) insulation and belongs to the HTSW series. LCP provides enhanced dimensional stability and lower moisture absorption compared to PBT, making it suitable for applications requiring superior thermal and environmental performance. This part carries a not-applicable moisture sensitivity designation.

All three connectors meet UL94 V-0 flammability requirements and operate across the full -55°C to 125°C temperature range. Selection should align with specific application requirements regarding insulation material properties and series compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can TSW-108-07-SS-D-LL be directly replaced with TSW-108-07-S-D-LL?

A: Yes. Both parts share identical electrical and mechanical specifications, including 16-position, 2-row configuration, 0.100" (2.54mm) pitch, through-hole kinked pin solder termination, phosphor bronze contacts with gold mating finish, and PBT insulation. The parts are functionally interchangeable.

Q: What is the primary difference between TSW-108-07-S-D-LL and HTSW-108-07-S-D-LL?

A: The primary difference is insulation material. TSW-108-07-S-D-LL uses polybutylene terephthalate (PBT), while HTSW-108-07-S-D-LL uses liquid crystal polymer (LCP). Both maintain identical contact configurations, pitch specifications, and operating temperature ranges. LCP offers superior dimensional stability and lower moisture absorption.

Q: Are all three parts ROHS3 compliant?

A: Yes. TSW-108-07-SS-D-LL, TSW-108-07-S-D-LL, and HTSW-108-07-S-D-LL all meet ROHS3 compliance requirements and carry EAR99 ECCN classification.

Q: What is the significance of the moisture sensitivity level (MSL) difference?

A: TSW-108-07-SS-D-LL and TSW-108-07-S-D-LL carry MSL 1 (unlimited), indicating no moisture sensitivity restrictions during storage or handling. HTSW-108-07-S-D-LL carries not-applicable MSL due to its LCP insulation material, which exhibits inherently lower moisture absorption. This does not affect functional compatibility.

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

A: Yes. All three parts operate across -55°C to 125°C, meeting industrial temperature requirements. The choice between PBT and LCP insulation may influence long-term performance in sustained high-temperature environments, with LCP providing enhanced thermal stability.

Q: Are the contact dimensions identical across all three parts?

A: Yes. All three parts maintain identical contact specifications: 0.230" (5.84mm) mating length, 0.100" (2.54mm) post length, 0.430" (10.92mm) overall length, and square contact shape with phosphor bronze material and gold/tin finish specifications.
