TSW-105-25-L-S-NA Equivalent & Substitute Parts

Part Overview

The TSW-105-25-L-S-NA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle mounting applications. This 5-position connector operates at 0.100" (2.54mm) pitch and features male pin contacts with gold-plated mating surfaces and tin-plated posts. The part is currently active in production with 782 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in board-level applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-105-25-L-S-NA is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Number of Positions: 5 — determines circuit connectivity
• Number of Rows: 1 — defines physical layout
• Connector Type: Header — functional classification
• Contact Type: Male Pin — electrical interface requirement
• Mounting Type: Through Hole, Right Angle — PCB assembly method
• Termination: Solder — connection method
• Contact Material: Phosphor Bronze — electrical and mechanical properties
• Contact Finish - Mating: Gold — corrosion resistance and signal integrity
• Operating Temperature Range: -55°C ~ 125°C — thermal operating envelope
• Material Flammability Rating: UL94 V-0 — safety compliance

The identified substitute parts maintain these critical parameters while allowing variation in insulation material composition and minor dimensional tolerances within acceptable engineering limits.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TSW-105-25-L-S-NA, TSW-105-25-L-S-RA, and HTSW-105-25-L-S-RA—maintain active product status and full ROHS3 compliance. Each part meets UL94 V-0 flammability requirements and operates across the identical temperature range of -55°C to 125°C.

The TSW-105-25-L-S-NA and TSW-105-25-L-S-RA differ only in series designation within the TSW family and share identical electrical and mechanical specifications, including PBT insulation material and 0.119" insulation height.

The HTSW-105-25-L-S-RA represents the HTSW series variant with Liquid Crystal Polymer (LCP) insulation material in place of PBT. The insulation height increases marginally to 0.122" (3.10mm), and the Moisture Sensitivity Level designation changes from MSL 1 (Unlimited) to Not Applicable, reflecting the material composition difference. All other critical parameters remain equivalent.

Selection between these parts depends on application-specific requirements for insulation material properties and board layout constraints related to the minor insulation height variation.

Frequently Asked Questions (FAQ)

Q: Can TSW-105-25-L-S-RA be used as a direct replacement for TSW-105-25-L-S-NA?

A: Yes. Both parts share identical pitch (0.100"), position count (5), contact configuration, mounting type (through-hole right-angle), and operating temperature range (-55°C to 125°C). The parts are electrically and mechanically interchangeable.

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

A: The HTSW-105-25-L-S-RA uses Liquid Crystal Polymer (LCP) insulation material versus Polybutylene Terephthalate (PBT) in the TSW series. The insulation height increases from 0.119" to 0.122". Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range.

Q: Does the insulation material change affect electrical performance?

A: The electrical performance parameters—contact material (Phosphor Bronze), contact finish (Gold mating surface, Tin posts), pitch (0.100"), and contact configuration—remain constant across all three parts. Insulation material selection is determined by application-specific environmental and mechanical requirements.

Q: Are all three parts RoHS compliant?

A: Yes. TSW-105-25-L-S-NA, TSW-105-25-L-S-RA, and HTSW-105-25-L-S-RA are all ROHS3 compliant.

Q: What does Moisture Sensitivity Level (MSL) 1 indicate?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling or storage conditions. The HTSW variant lists MSL as Not Applicable due to its LCP insulation material composition.

Q: Can these connectors be used in high-temperature applications?

A: All three parts operate across -55°C to 125°C. Applications requiring operation beyond this range require alternative connector selection.

Q: What is the contact finish thickness specification?

A: The mating contact gold finish is 10.0µin (0.25µm) across all three parts, providing consistent corrosion resistance and signal integrity.
