TSW-102-24-S-S Equivalent & Substitute Parts

Part Overview

The TSW-102-24-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable connections. This 2-position, single-row header operates across an extended temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the core functional requirements remain unchanged.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-102-24-S-S is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — ensures mechanical and electrical compatibility with mating connectors
• Number of Positions: 2 — maintains circuit configuration and PCB footprint compatibility
• Number of Rows: 1 — preserves board layout and spacing requirements
• Contact Type: Male Pin — ensures proper mating interface
• Mounting Type: Through Hole — maintains assembly process compatibility
• Termination: Solder — ensures compatible soldering and assembly methods
• Contact Finish - Mating: Gold — provides equivalent electrical contact performance
• Insulation Material: Polybutylene Terephthalate (PBT) — maintains mechanical and thermal stability
• Material Flammability Rating: UL94 V-0 — ensures equivalent safety compliance

The 3M 929450-01-02-I meets all critical substitution parameters. Minor variations in contact length, insulation height, and operating temperature range do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-102-24-S-S and 929450-01-02-I maintain Active product status and meet UL94 V-0 flammability requirements. The TSW-102-24-S-S supports an extended operating temperature range of -55°C to 125°C, while the 929450-01-02-I operates within -40°C to 105°C. Selection between these parts depends on application temperature requirements. The TSW-102-24-S-S is suitable for applications requiring the full extended temperature range; the 929450-01-02-I is suitable for applications operating within its specified range. Both parts feature gold-plated mating contacts and PBT insulation with UL94 V-0 rating. The 929450-01-02-I provides a specified current rating of 2.5A, while the TSW-102-24-S-S does not specify a current rating in the provided data. Compliance certifications (RoHS3 for Samtec, REACH Unaffected for 3M) differ by manufacturer but do not preclude substitution based on regulatory status alone.

Frequently Asked Questions (FAQ)

Q: Can the 929450-01-02-I replace the TSW-102-24-S-S in all applications?

A: The 929450-01-02-I is a suitable substitute when the application operates within its specified temperature range of -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the TSW-102-24-S-S, which supports -55°C to 125°C.

Q: What is the significance of the contact length differences between these parts?

A: The TSW-102-24-S-S has a mating contact length of 0.265" (6.73mm) and overall contact length of 0.480" (12.19mm). The 929450-01-02-I has a mating contact length of 0.295" (7.49mm) and overall contact length of 0.535" (14.69mm). These differences affect mating depth and board clearance. Verify PCB layout and mating connector specifications before substitution.

Q: Are the pitch and position specifications identical?

A: Yes. Both parts feature 0.100" (2.54mm) pitch, 2 positions, and 1 row. These core parameters are identical, ensuring mechanical compatibility with standard 2.54mm pitch mating connectors and PCB footprints.

Q: What is the difference between the contact finish specifications?

A: The TSW-102-24-S-S features 30.0µin (0.76µm) gold plating on mating contacts. The 929450-01-02-I features 10.0µin (0.25µm) gold plating. Both provide gold-plated mating surfaces for equivalent electrical contact performance; the difference is plating thickness.

Q: Do both parts use the same insulation material?

A: Both use Polybutylene Terephthalate (PBT). The 929450-01-02-I specifies PBT with polyester and glass filler, providing enhanced mechanical properties. Both meet UL94 V-0 flammability requirements.

Q: What is the breakaway feature on the 929450-01-02-I?

A: The 929450-01-02-I is designated as a breakaway header, allowing individual positions to be separated if required. The TSW-102-24-S-S is a standard unshrouded header without this feature.

Q: Are there moisture sensitivity differences?

A: The TSW-102-24-S-S has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 929450-01-02-I is listed as Not Applicable for MSL, indicating no moisture sensitivity concern. Both parts are suitable for standard storage and handling conditions.
