TSW-104-25-G-D-LA Equivalent & Substitute Parts

Part Overview

The TSW-104-25-G-D-LA is an 8-position rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This unshrouded header features a 0.100" (2.54mm) pitch with kinked pin solder termination and push-pull fastening. The part is currently active in production with 938 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part may be unavailable or require alternative material properties.

Key Parameters

Substitute Part Grouping Explanation

The HTSW-104-25-G-D-LA qualifies as a substitute for the TSW-104-25-G-D-LA based on alignment of critical electrical and mechanical parameters. Both parts share identical specifications for connector type (header), contact type (male pin), position count (8), row configuration (2 rows), mating pitch (0.100"), row spacing (0.100"), mounting method (through hole, right angle), termination style (kinked pin, solder), contact finish (gold), contact material (phosphor bronze), and operating temperature range (-55°C ~ 125°C). Both parts maintain UL94 V-0 flammability rating and ROHS3 compliance. Substitution is valid where these core parameters determine functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-104-25-G-D-LA and HTSW-104-25-G-D-LA are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on insulation material and dimensional requirements. The TSW-104-25-G-D-LA uses polybutylene terephthalate (PBT) insulation with an insulation height of 0.219" (5.56mm) and black color. The HTSW-104-25-G-D-LA uses liquid crystal polymer (LCP) insulation with an insulation height of 0.240" (6.10mm) and natural color. Both parts maintain identical electrical and mechanical interface specifications, including contact geometry, pitch, termination, and operating temperature range. Selection should be based on PCB layout constraints related to insulation height and application requirements for insulation material properties.

Frequently Asked Questions (FAQ)

Q: Can the HTSW-104-25-G-D-LA directly replace the TSW-104-25-G-D-LA in existing designs?

A: Direct substitution is valid for applications where the increased insulation height (0.240" versus 0.219") and alternative insulation material (LCP versus PBT) do not create PCB layout conflicts. Both parts share identical contact pitch, mating interface, and electrical specifications.

Q: What is the difference between the insulation materials used in these parts?

A: The TSW-104-25-G-D-LA uses polybutylene terephthalate (PBT), while the HTSW-104-25-G-D-LA uses liquid crystal polymer (LCP). Both materials meet UL94 V-0 flammability requirements. Material selection should be based on specific application thermal and mechanical requirements.

Q: Are both parts RoHS compliant?

A: Both the TSW-104-25-G-D-LA and HTSW-104-25-G-D-LA are ROHS3 compliant with identical export classification (EAR99) and tariff codes (8536.69.4040).

Q: What are the critical parameters for substitution between these parts?

A: Substitution is valid based on matching connector type (header), contact type (male pin), position count (8), row configuration (2 rows), mating pitch (0.100"), row spacing (0.100"), mounting method (through hole, right angle), termination (kinked pin, solder), contact finish (gold), contact material (phosphor bronze), and operating temperature range (-55°C ~ 125°C).

Q: Does the difference in insulation height affect connector mating?

A: The insulation height difference (0.021" or 0.54mm) does not affect mating interface compatibility. Both parts maintain identical contact length and mating specifications. Consideration should be given to PCB layout and clearance requirements.
