TMS-115-03-S-S-RA Equivalent & Substitute Parts

Part Overview

The TMS-115-03-S-S-RA is a 0.050" (1.27mm) pitch micro header connector manufactured by Samtec Inc. This through-hole, right-angle header features 15 positions in a single row configuration with male pin contacts, designed for board-to-board applications. The connector is currently active in production with 1138 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to component availability, supply chain considerations, or design flexibility within the allowed parameter specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS-115-03-S-S-RA is determined by strict alignment with the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm) - exact match required
• Number of Positions: 15 - exact match required
• Number of Rows: 1 - exact match required
• Connector Type: Header - exact match required
• Contact Type: Male Pin - exact match required
• Mounting Type: Through Hole, Right Angle - exact match required
• Termination: Solder - exact match required
• Shrouding: Unshrouded - exact match required
• Contact Finish - Mating: Gold - exact match required
• Material Flammability Rating: UL94 V-0 - exact match required
• RoHS Status: ROHS3 Compliant - exact match required

The TE Connectivity AMP Connectors part 5-104186-9 meets all critical substitution parameters and is classified as a direct equivalent within the allowed electrical and mechanical specifications for this product category.

Parameter Comparison

Engineering Selection Recommendations

The TMS-115-03-S-S-RA remains the primary selection for new designs due to its active production status and current availability of 1138 units in stock. Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting equivalent regulatory requirements.

The TE Connectivity 5-104186-9 is classified as a direct equivalent based on matching critical electrical and mechanical parameters. However, this part is discontinued at DiGi Electronics, limiting its suitability for ongoing procurement. Selection of the substitute should be based on specific design requirements regarding operating temperature range, contact post length, and insulation height specifications, as these parameters differ between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the 5-104186-9 be used as a direct replacement for the TMS-115-03-S-S-RA?

A: The 5-104186-9 meets all critical substitution parameters including pitch, position count, connector type, contact type, mounting configuration, and compliance certifications. However, differences in contact post length (0.100" vs. 0.140"), insulation height (0.116" vs. 0.098"), and operating temperature range (-65°C ~ 105°C vs. -55°C ~ 125°C) must be evaluated against specific application requirements.

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

A: Primary differences include contact post length, insulation height, contact shape (square vs. circular), insulation material (LCP vs. thermoplastic), and operating temperature range. The mating contact length, pitch, position count, and mounting configuration are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the TMS-115-03-S-S-RA and 5-104186-9 are ROHS3 compliant with UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels.

Q: Why is the 5-104186-9 discontinued?

A: The product status reflects discontinuation at DiGi Electronics. Availability through alternative distributors or direct manufacturer channels may vary.

Q: What should I consider when selecting between these parts?

A: Evaluate application-specific requirements for operating temperature range, PCB layout constraints related to contact post length and insulation height, and long-term supply chain availability. The TMS-115-03-S-S-RA is recommended for new designs due to active production status.
