TSW-108-08-G-D-NA Equivalent & Substitute Parts

Part Overview

The TSW-108-08-G-D-NA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 16-position connector operates across -55°C to 125°C and features gold-plated phosphor bronze contacts with 0.100" (2.54mm) pitch spacing. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies requiring standard rectangular connector solutions.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in compatible applications without redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-108-08-G-D-NA is determined by strict alignment of the following parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 16
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these criteria are classified as direct substitutes. Variations in insulation material, insulation height, or contact finish thickness do not preclude substitution when all primary electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TSW-108-08-G-D-NA, TSW-108-08-G-D-RA, and HTSW-108-08-G-D-RA—maintain Active product status and full ROHS3 compliance. Selection between these parts is based on specific application requirements:

TSW-108-08-G-D-NA and TSW-108-08-G-D-RA are both TSW series connectors with identical electrical and mechanical specifications, differing only in part number designation. Both feature PBT insulation material and 0.219" (5.56mm) insulation height.

HTSW-108-08-G-D-RA represents the HTSW series variant, which maintains all critical electrical and mechanical parameters but incorporates Liquid Crystal Polymer (LCP) insulation material and a slightly increased insulation height of 0.240" (6.10mm). This material substitution does not affect core connector functionality but may influence thermal or chemical resistance characteristics in specific environments.

All parts carry identical contact specifications, pitch dimensions, and temperature ratings, ensuring functional interchangeability in standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can TSW-108-08-G-D-RA be used as a direct replacement for TSW-108-08-G-D-NA?

A: Yes. Both parts share identical electrical and mechanical parameters, including 16-position configuration, 0.100" (2.54mm) pitch, gold-plated phosphor bronze contacts, and -55°C to 125°C operating temperature range. The part number difference does not indicate functional variation.

Q: What is the primary difference between the TSW and HTSW series?

A: The HTSW-108-08-G-D-RA differs from TSW variants in insulation material composition (Liquid Crystal Polymer versus Polybutylene Terephthalate) and insulation height (0.240" versus 0.219"). All other electrical and mechanical specifications remain equivalent.

Q: Are all three parts ROHS3 compliant?

A: Yes. TSW-108-08-G-D-NA, TSW-108-08-G-D-RA, and HTSW-108-08-G-D-RA are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Does insulation material affect connector performance in standard applications?

A: Insulation material selection impacts thermal stability and chemical resistance. PBT and LCP both meet UL94 V-0 flammability requirements and operate across the specified -55°C to 125°C range. Material selection should align with specific environmental exposure requirements.

Q: What is the significance of the contact finish thickness specifications?

A: Mating contact finish thickness of 10.0µin (0.25µm) and post contact finish thickness of 3.00µin (0.076µm) define durability and electrical performance characteristics. All three parts maintain identical specifications in this parameter.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes, provided the PCB footprint accommodates the specific insulation height. TSW series parts (0.219" insulation height) and HTSW series parts (0.240" insulation height) may require footprint verification for mechanical fit, though electrical compatibility is maintained.
