TSW-102-09-G-D-RA Equivalent & Substitute Parts

Part Overview

The TSW-102-09-G-D-RA is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This unshrouded header features 4 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing and gold-plated phosphor bronze contacts. The component is RoHS3 compliant with UL94 V-0 flammability rating and operates across -55°C to 125°C. Finding equivalent or substitute parts may be necessary for supply chain continuity, inventory optimization, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-102-09-G-D-RA is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 4
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish - Mating: Gold
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The HTSW-102-09-G-D-RA meets all critical substitution criteria. Both parts share identical mating pitch, position count, row configuration, mounting orientation, contact material (phosphor bronze with gold plating), operating temperature range, and regulatory compliance. Variations in insulation material (PBT versus LCP) and insulation height do not affect functional interchangeability for standard board-to-board or cable applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-102-09-G-D-RA and HTSW-102-09-G-D-RA are active products from Samtec Inc. with identical regulatory compliance profiles. Selection between these parts should be based on:

• Product availability and lead time requirements
• Inventory status (TSW-102-09-G-D-RA: 812 pcs; HTSW-102-09-G-D-RA: 720 pcs)
• Insulation material preference (PBT versus LCP)
• Mechanical tolerance requirements related to insulation height variation (0.219" versus 0.240")

Both parts maintain RoHS3 compliance, UL94 V-0 flammability rating, and identical electrical and mechanical interface specifications. The choice between them does not compromise functional performance or regulatory standing.

Frequently Asked Questions (FAQ)

Q: Are TSW-102-09-G-D-RA and HTSW-102-09-G-D-RA mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (4), row configuration (2 rows), contact geometry, and mounting orientation (through-hole, right-angle). The insulation material difference (PBT versus LCP) does not affect mechanical interchangeability in standard applications.

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

A: TSW-102-09-G-D-RA has an insulation height of 0.219" (5.56mm), while HTSW-102-09-G-D-RA has 0.240" (6.10mm). This 0.021" (0.54mm) difference may be relevant for applications with tight vertical clearance constraints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are RoHS3 compliant, UL94 V-0 rated, and classified under the same HTSUS code (8536.69.4040) and ECCN (EAR99).

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

A: TSW-102-09-G-D-RA uses Polybutylene Terephthalate (PBT), while HTSW-102-09-G-D-RA uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 requirements. LCP offers superior dimensional stability and lower moisture absorption, which may be beneficial in high-humidity or precision-tolerance applications.

Q: Are the contact specifications identical?

A: Yes. Both parts feature phosphor bronze contacts with gold plating (10.0µin mating finish, 3.00µin post finish), identical contact length specifications (0.230" mating, 0.290" post), and square contact geometry.

Q: Can I substitute one part for the other without design changes?

A: Substitution is possible for most applications. However, verify insulation height clearance in your specific PCB layout, as the 0.021" difference may affect board-to-board spacing or component proximity constraints.
