TSW-102-23-G-S Equivalent & Substitute Parts

Part Overview

The TSW-102-23-G-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications requiring a 2-position, 0.100" (2.54mm) pitch vertical header. This connector is classified as discontinued at DiGi Electronics, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement.

The part serves as a board-to-board or cable interface with unshrouded male pin contacts, gold-plated mating surfaces, and phosphor bronze contact material. Due to its discontinued status, sourcing equivalent components with matching electrical and mechanical specifications is necessary for production continuity and design flexibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-102-23-G-S is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 2
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Insulation Material: Polybutylene Terephthalate (PBT)

The substitute part 929647-01-02-I (3M) meets all primary matching criteria. Variations in contact length specifications, operating temperature range, and contact material composition remain within acceptable tolerance for functional equivalence in standard through-hole header applications.

Parameter Comparison

Engineering Selection Recommendations

The 929647-01-02-I (3M) connector qualifies as a functional equivalent to the TSW-102-23-G-S based on alignment of all critical electrical and mechanical parameters. The substitute part maintains identical pitch, position count, row configuration, contact geometry, and gold plating specifications.

Key considerations for selection:

Compliance & Certification: Both parts maintain UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels. The 929647-01-02-I carries active RoHS compliance status, whereas the TSW-102-23-G-S is ROHS3 compliant. Both meet REACH unaffected classification.

Product Availability: The 929647-01-02-I maintains active product status with documented inventory availability, addressing the discontinued status of the original part.

Operating Temperature Differential: The TSW-102-23-G-S supports -55°C to 125°C operation, while the 929647-01-02-I operates within -40°C to 105°C. Applications requiring the full lower temperature range of the original part require thermal performance verification.

Contact Material Variation: The substitute employs copper alloy contacts versus phosphor bronze in the original. Both materials provide equivalent electrical conductivity and corrosion resistance for standard through-hole header applications.

Frequently Asked Questions (FAQ)

Q: Can the 929647-01-02-I directly replace the TSW-102-23-G-S in existing PCB designs?

A: Yes, for applications operating within the -40°C to 105°C temperature range. The substitute maintains identical pitch (2.54mm), position count (2), row configuration (1), and contact geometry. PCB footprints designed for the TSW-102-23-G-S accommodate the 929647-01-02-I without modification.

Q: What is the significance of the "Breakaway" designation on the 929647-01-02-I?

A: The breakaway feature allows individual connector positions to be separated from the header strip. This does not affect compatibility with standard through-hole PCB applications and provides additional design flexibility for applications requiring modular connector configurations.

Q: Are there thermal performance differences between these connectors?

A: The TSW-102-23-G-S supports continuous operation to 125°C, while the 929647-01-02-I is rated to 105°C. Applications requiring operation above 105°C must retain the original part or identify alternative solutions. Standard room-temperature and moderate-temperature applications experience no functional difference.

Q: How do the contact materials affect electrical performance?

A: Phosphor bronze (TSW-102-23-G-S) and copper alloy (929647-01-02-I) both provide low contact resistance and reliable electrical conductivity for standard signal and power distribution applications. Contact finish (gold plating) is identical at 10.0µin thickness, ensuring equivalent mating surface performance.

Q: Is the 929647-01-02-I suitable for high-reliability applications?

A: Both connectors meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The 929647-01-02-I maintains active product status with documented supply chain availability, supporting consistent procurement for production environments.

Q: What packaging differences exist between these parts?

A: The TSW-102-23-G-S packaging is not specified in available documentation. The 929647-01-02-I is supplied in bulk packaging. Verify packaging requirements with component suppliers for specific application needs.
