TSW-103-08-S-D-RA Equivalent & Substitute Parts

Part Overview

The TSW-103-08-S-D-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 6-position, 2-row connector operates across -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 tolerance. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility while maintaining circuit performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-103-08-S-D-RA is determined by alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Termination: Solder
• Connector Category: Rectangular Connectors, Header
• Material Flammability Rating: UL94 V-0
• RoHS Compliance Status

The identified substitute part 929647-02-03-I from 3M shares the core mating pitch of 2.54mm, male pin contact type, solder termination, and equivalent flammability rating. However, this substitute differs in position count (3 vs. 6), row configuration (1 vs. 2), and mounting orientation (vertical vs. right-angle). These differences restrict substitution to applications where the reduced position count and vertical mounting are compatible with circuit board layout and connector interface requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-103-08-S-D-RA and 929647-02-03-I maintain Active product status with current manufacturer support. The Samtec part provides extended operating temperature range (-55°C to 125°C) compared to the 3M substitute (-40°C to 105°C), making the original part suitable for applications requiring broader thermal performance. Both parts meet UL94 V-0 flammability requirements and maintain RoHS compliance, supporting environmental and safety standards.

Selection between these parts depends on application-specific requirements: the TSW-103-08-S-D-RA is appropriate for designs requiring 6-position, 2-row right-angle configuration with extended temperature range, while the 929647-02-03-I serves applications compatible with 3-position, single-row vertical mounting within the narrower temperature window.

Frequently Asked Questions (FAQ)

Q: Can the 929647-02-03-I directly replace the TSW-103-08-S-D-RA in existing designs?

A: Direct replacement is not possible due to differences in position count (3 vs. 6), row configuration (1 vs. 2), and mounting orientation (vertical vs. right-angle). Circuit board layout and connector interface design must accommodate these mechanical differences.

Q: What is the significance of the 2.54mm pitch specification?

A: The 0.100" (2.54mm) mating pitch defines the center-to-center spacing between adjacent contacts. Both parts share this pitch, enabling compatibility with standard 2.54mm connector receptacles and breadboard interfaces.

Q: Are there temperature limitations when using the 929647-02-03-I as a substitute?

A: Yes. The 3M part operates within -40°C to 105°C, compared to the Samtec part's -55°C to 125°C range. Applications requiring operation below -40°C or above 105°C must use the original TSW-103-08-S-D-RA.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated and RoHS compliant. The TSW-103-08-S-D-RA carries RoHS3 certification, while the 929647-02-03-I carries standard RoHS certification. Both are REACH unaffected and classified as EAR99.

Q: What packaging considerations apply to these connectors?

A: Both parts are supplied in bulk packaging. The TSW-103-08-S-D-RA is available with 756 pieces in stock, while the 929647-02-03-I has 2157 pieces available. Moisture sensitivity level (MSL) differs: the Samtec part is MSL 1 (unlimited), while the 3M part is not applicable.
