TSW-109-08-G-S-RA Equivalent & Substitute Parts

Part Overview

The TSW-109-08-G-S-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 9-position connector operates at 0.100" (2.54mm) pitch and features gold-plated phosphor bronze contacts with solder termination. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part is unavailable or when design flexibility permits component selection from alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSW-109-08-G-S-RA are evaluated based on the following critical parameters that determine functional compatibility:

• Pitch - Mating: 0.100" (2.54mm) — ensures mechanical and electrical compatibility with mating connectors
• Connector Type: Header with Male Pin contacts — maintains board-to-board or cable connection capability
• Mounting Type: Through Hole, Right Angle — preserves PCB assembly method and spatial orientation
• Termination: Solder — ensures compatibility with standard PCB assembly processes
• Contact Finish: Gold plating — maintains electrical performance and corrosion resistance
• Operating Temperature Range: Must support the application's thermal requirements
• Material Flammability: UL94 V-0 rating — meets safety and regulatory standards

The substitute part 4-103765-0 (TE Connectivity AMP Connectors) shares the core electrical and mechanical parameters required for substitution. However, critical differences exist in position count, insulation material, operating temperature range, and compliance status that must be evaluated for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The TSW-109-08-G-S-RA remains the preferred choice for new designs due to its Active product status and RoHS3 compliance. The part is currently in stock with 830 units available.

The 4-103765-0 substitute exhibits Obsolete product status and RoHS non-compliance, which restricts its use in applications subject to RoHS regulations or requiring long-term component availability. Additionally, the 40-position configuration of the substitute part differs significantly from the 9-position main part, requiring circuit redesign or selective position utilization. The operating temperature range of the substitute (-65°C ~ 105°C) is narrower at the upper limit compared to the main part (-55°C ~ 125°C), which may be limiting for high-temperature applications.

Selection of the substitute part should be limited to legacy system maintenance or applications where RoHS compliance is not required and the 40-position breakaway configuration can be accommodated through design modification.

Frequently Asked Questions (FAQ)

Q: Can the 4-103765-0 be used as a direct replacement for the TSW-109-08-G-S-RA?

A: Direct replacement is not recommended. While both connectors share the same 0.100" (2.54mm) pitch and through-hole right-angle mounting, the substitute part has 40 positions versus 9 positions in the main part. The substitute is also Obsolete and RoHS non-compliant, making it unsuitable for applications requiring regulatory compliance or long-term availability.

Q: What are the key compatibility criteria for substituting these connectors?

A: Substitution requires matching the following parameters: 0.100" (2.54mm) mating pitch, male pin contact type, through-hole right-angle mounting, solder termination, and gold-plated mating contacts. Operating temperature range and compliance certifications must also be evaluated for the specific application.

Q: Does the difference in insulation height affect compatibility?

A: The insulation height difference (0.119" for TSW-109-08-G-S-RA versus 0.138" for 4-103765-0) may impact PCB layout and clearance requirements. This should be verified against the specific application's spatial constraints and mating connector specifications.

Q: Why is RoHS compliance important for connector selection?

A: RoHS3 compliance is mandatory for products sold in the European Union and many other markets. The TSW-109-08-G-S-RA meets this requirement, while the 4-103765-0 does not. Non-compliant parts may not be acceptable for new designs or applications subject to regulatory requirements.

Q: What is the significance of the Obsolete status for the substitute part?

A: Obsolete status indicates that the 4-103765-0 is no longer in active production. This restricts future availability, increases lead times, and may result in higher costs. The TSW-109-08-G-S-RA's Active status ensures continued availability and stable pricing for production requirements.
