Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-128-08-G-D is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Configuration: 56 positions arranged in 2 rows
Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole solder termination
Electrical Performance: Operating temperature range of -55°C to 125°C
Contact Properties: Gold-plated mating surface with phosphor bronze material
Compliance: RoHS3 compliance and UL94 V-0 flammability rating

The TSW-128-08-G-D meets all critical substitution criteria. Both parts share identical connector architecture, position configuration, pitch specifications, mounting methodology, and temperature operating range. Differences in insulation material (LCP versus PBT) and insulation color do not affect functional interchangeability in standard board-to-board or cable connection applications.

Engineering Selection Recommendations

Both the HTSW-128-08-G-D and TSW-128-08-G-D are active production parts from Samtec Inc. with full RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

HTSW-128-08-G-D: Primary selection when LCP insulation material is specified or preferred for applications requiring enhanced dimensional stability or specific thermal characteristics.

TSW-128-08-G-D: Suitable alternative when PBT insulation material meets application requirements or when supply availability of the HTSW variant is constrained. The TSW series maintains identical electrical and mechanical performance characteristics.

Both parts carry equivalent compliance certifications and support identical operating temperature ranges, making them functionally interchangeable for standard through-hole connector applications.

Frequently Asked Questions (FAQ)

Q: Are HTSW-128-08-G-D and TSW-128-08-G-D mechanically interchangeable?

A: Yes. Both connectors share identical pitch specifications (0.100" mating and row spacing), position count (56 positions in 2 rows), contact geometry, and overall dimensions. They mount identically in through-hole applications.

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

A: LCP (Liquid Crystal Polymer) and PBT (Polybutylene Terephthalate) are both thermoplastic insulation materials rated UL94 V-0. The primary difference is material composition; both provide equivalent electrical insulation and flammability performance for this connector application.

Q: Can I substitute TSW-128-08-G-D for HTSW-128-08-G-D in existing designs?

A: Yes, provided the design does not explicitly specify LCP insulation material. The TSW variant maintains all critical electrical and mechanical parameters required for functional compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both HTSW-128-08-G-D and TSW-128-08-G-D are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the operating temperature range for both connectors?

A: Both parts operate across -55°C to 125°C, supporting applications in industrial, automotive, and consumer electronics environments.

Q: Do these connectors require any special handling or storage considerations?

A: The HTSW-128-08-G-D carries Moisture Sensitivity Level (MSL) designation as Not Applicable. The TSW-128-08-G-D carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for either part.
