TSW-105-20-G-D-LL Equivalent & Substitute Parts

Part Overview

The TSW-105-20-G-D-LL is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This vertical header connector features 10 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnections. The connector utilizes kinked pin solder termination with push-pull fastening and gold-plated phosphor bronze contacts. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TSW-105-20-G-D-LL is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 10 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
• Fastening Mechanism: Push-pull fastening type
• Contact Material & Finish: Phosphor bronze with gold plating on mating surfaces
• Operating Temperature Range: -55°C ~ 125°C
• Compliance Standards: UL94 V-0 flammability rating and ROHS3 compliance

The HTSW-105-20-G-D-LL qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. Variations in insulation material (Liquid Crystal Polymer vs. Polybutylene Terephthalate) and insulation color do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-105-20-G-D-LL and HTSW-105-20-G-D-LL are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

Product Availability: The TSW-105-20-G-D-LL currently has 716 pieces in stock, while the HTSW-105-20-G-D-LL has 648 pieces available. Either part may be selected based on inventory requirements and lead time considerations.

Compliance & Certification: Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements, making them suitable for equivalent applications.

Material Considerations: The TSW-105-20-G-D-LL uses Polybutylene Terephthalate (PBT) insulation with black coloring, while the HTSW-105-20-G-D-LL uses Liquid Crystal Polymer (LCP) insulation with natural coloring. Both materials provide equivalent electrical performance and thermal stability across the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can HTSW-105-20-G-D-LL be used as a direct replacement for TSW-105-20-G-D-LL?

A: Yes. Both connectors share identical electrical and mechanical specifications including pitch, position count, row configuration, contact material, contact finish, termination type, and operating temperature range. The difference in insulation material (LCP vs. PBT) does not affect functional compatibility in standard applications.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: connector type (header), contact type (male pin), number of positions (10), number of rows (2), mating pitch (0.100"), row spacing (0.100"), mounting type (through-hole), termination (kinked pin solder), fastening type (push-pull), contact material (phosphor bronze), contact finish (gold), and operating temperature range (-55°C to 125°C).

Q: Are there differences in insulation material between these parts?

A: Yes. The TSW-105-20-G-D-LL uses Polybutylene Terephthalate (PBT) insulation, while the HTSW-105-20-G-D-LL uses Liquid Crystal Polymer (LCP) insulation. Both materials provide equivalent electrical performance and thermal stability. The choice between them depends on specific application requirements regarding material properties, though both are suitable for standard board-to-board and cable interconnection applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TSW-105-20-G-D-LL and HTSW-105-20-G-D-LL are ROHS3 compliant and carry a UL94 V-0 flammability rating. Both are active products with identical regulatory status.

Q: What is the difference in insulation color?

A: The TSW-105-20-G-D-LL features black insulation, while the HTSW-105-20-G-D-LL features natural-colored insulation. This is a visual distinction only and does not affect electrical or mechanical performance.
