TSW-107-25-G-S-RA Equivalent & Substitute Parts

Part Overview

The TSW-107-25-G-S-RA is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 7-position connector operates at 0.100" (2.54mm) pitch and features gold-plated phosphor bronze contacts with solder termination. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application needs while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-107-25-G-S-RA is determined by the following critical parameters:

Number of Positions: Must be 7
Pitch - Mating: Must be 0.100" (2.54mm)
Mounting Type: Must be Through Hole, Right Angle
Contact Type: Must be Male Pin
Contact Finish - Mating: Must be Gold
Contact Material: Must be Phosphor Bronze
Operating Temperature Range: Must be -55°C ~ 125°C
Material Flammability Rating: Must be UL94 V-0
RoHS Status: Must be ROHS3 Compliant

The HTSW-107-25-G-S-RA qualifies as a substitute part because it meets all critical electrical and mechanical parameters. Minor variations in insulation material (Liquid Crystal Polymer vs. Polybutylene Terephthalate) and insulation height (0.122" vs. 0.119") do not affect functional compatibility in standard applications.

Engineering Selection Recommendations

Both the TSW-107-25-G-S-RA and HTSW-107-25-G-S-RA are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on:

Inventory Availability: HTSW-107-25-G-S-RA currently has 1118 units in stock versus 721 units for TSW-107-25-G-S-RA
Insulation Material Requirements: TSW-107-25-G-S-RA uses PBT insulation; HTSW-107-25-G-S-RA uses LCP insulation. LCP offers superior dimensional stability and chemical resistance in demanding environments
Mechanical Tolerance: The insulation height difference of 0.003" (0.08mm) is negligible for standard board-to-board applications but should be verified for space-constrained designs

Both parts maintain identical electrical performance, contact geometry, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can HTSW-107-25-G-S-RA be used as a direct replacement for TSW-107-25-G-S-RA?

A: Yes. Both parts share identical connector type, position count, pitch, mounting configuration, contact material, and gold plating specifications. The insulation material difference (LCP vs. PBT) does not affect electrical compatibility in standard applications.

Q: What is the significance of the insulation material difference?

A: Polybutylene Terephthalate (PBT) and Liquid Crystal Polymer (LCP) are both thermoplastic materials with UL94 V-0 ratings. LCP provides enhanced dimensional stability and chemical resistance. For most applications, either material is functionally equivalent.

Q: Does the 0.003" insulation height difference affect PCB layout?

A: The insulation height variation (0.119" vs. 0.122") is within typical manufacturing tolerances and should not impact standard board-to-board spacing. Verify clearance for applications with tight mechanical constraints.

Q: Are both parts RoHS compliant?

A: Yes. Both TSW-107-25-G-S-RA and HTSW-107-25-G-S-RA are ROHS3 compliant with identical gold contact finishes and phosphor bronze base material.

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

A: Both parts operate across -55°C to 125°C, supporting industrial and commercial temperature requirements.

Q: Are there any differences in contact finish specifications?

A: No. Both parts feature identical gold plating at 10.0µin (0.25µm) on mating contacts and 3.00µin (0.076µm) on posts, ensuring equivalent electrical performance and corrosion resistance.
