TSW-104-10-G-D-RA Equivalent & Substitute Parts

Part Overview

The TSW-104-10-G-D-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 8-position connector operates across a wide temperature range of -55°C to 125°C and features gold-plated phosphor bronze contacts with PBT insulation. The part is currently active in production with 1054 units in stock and maintains full RoHS3 compliance with MSL Level 1 rating.

Substitute parts are identified when equivalent connectors share the same mating pitch, position count, contact configuration, and core electrical/mechanical specifications, enabling direct functional replacement in applications where the main part is unavailable or supply constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-104-10-G-D-RA is determined by strict alignment of the following critical parameters:

• Mating Pitch: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Position Count: 8 positions in 2-row configuration — determines contact density and PCB footprint
• Connector Type: Header with male pins — defines mating interface
• Mounting Style: Through-hole, right-angle — establishes board attachment method
• Contact Finish: Gold-plated mating surface — ensures electrical performance and corrosion resistance
• Insulation Material: PBT-based — provides thermal and mechanical stability
• Termination Method: Solder — specifies connection to PCB

The substitute part 929667-02-04-I (3M) meets these core substitution criteria. Both parts share identical mating pitch, position configuration, connector type, mounting method, and contact finish specifications. Variations in contact material composition, insulation height tolerances, and operating temperature ranges represent acceptable engineering differences within the rectangular connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-104-10-G-D-RA and 929667-02-04-I are active production parts with current inventory availability. Selection between these parts should be based on application-specific operating conditions:

TSW-104-10-G-D-RA (Samtec) is suitable for applications requiring extended temperature operation down to -55°C or up to 125°C. This part carries ROHS3 compliance and MSL Level 1 rating, indicating compatibility with unlimited moisture exposure and modern manufacturing processes.

929667-02-04-I (3M) operates within the -40°C to 105°C temperature range and carries standard RoHS compliance. This part includes a current rating specification of 2.5A and features glass-filled polyester insulation in addition to PBT, providing enhanced mechanical properties in certain applications.

Both parts meet UL94 V-0 flammability requirements and maintain gold-plated mating contacts. The choice between them depends on whether the application requires the extended temperature range of the Samtec part or the specified current rating and enhanced insulation properties of the 3M part.

Frequently Asked Questions (FAQ)

Q: Can the 929667-02-04-I directly replace the TSW-104-10-G-D-RA in existing designs?

A: Yes, for applications operating within the -40°C to 105°C temperature range. Both parts share identical mating pitch (0.100"), position count (8 in 2 rows), contact configuration (male pins, square shape), mounting method (through-hole right-angle), and contact finish (gold-plated). PCB footprints are compatible. Applications requiring operation below -40°C or above 105°C must use the TSW-104-10-G-D-RA.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (TSW-104: -55°C to 125°C vs. 929667: -40°C to 105°C), contact material composition (phosphor bronze vs. copper alloy), insulation material formulation (PBT vs. PBT with glass-filled polyester), and current rating specification (929667 specifies 2.5A). Both maintain equivalent electrical and mechanical performance within their respective operating ranges.

Q: Are there any compliance or certification differences?

A: Both parts carry UL94 V-0 flammability ratings and RoHS compliance. The TSW-104-10-G-D-RA specifies ROHS3 compliance with MSL Level 1 rating, while the 929667-02-04-I carries standard RoHS compliance with MSL not applicable. For applications requiring ROHS3 or MSL Level 1 certification, the Samtec part is the appropriate selection.

Q: How do the contact dimensions compare?

A: Contact length specifications differ slightly. The TSW-104-10-G-D-RA has mating contact length of 0.230" (5.84mm) and post length of 0.390" (9.91mm), while the 929667-02-04-I has mating contact length of 0.235" (5.97mm) and post length of 0.405" (10.29mm). Insulation height also varies (TSW-104: 0.219" vs. 929667: 0.215"). These dimensional variations are within acceptable tolerances for standard rectangular connector applications.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For designs requiring extended temperature operation (-55°C minimum or 125°C maximum), ROHS3 compliance, or unlimited moisture exposure, specify the TSW-104-10-G-D-RA. For applications within standard industrial temperature ranges with specified current requirements, the 929667-02-04-I offers equivalent functionality with enhanced insulation properties.
