TMS-150-02-S-D Equivalent & Substitute Parts

Part Overview

The TMS-150-02-S-D is a 0.050" (1.27mm) pitch micro header connector manufactured by Samtec Inc., designed for board-to-board applications with through-hole solder termination. This unshrouded, 100-position, 2-row rectangular connector features male pins with gold-plated mating contacts and tin-plated posts. The connector is classified as Active product status with full RoHS3 compliance and UL94 V-0 flammability rating. Equivalent substitute parts are identified based on matching core electrical and mechanical parameters including pitch, position count, row configuration, contact material specifications, and termination method.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMS-150-02-S-D are qualified based on the following critical parameters that must match or remain compatible:

• Pitch - Mating: 0.050" (1.27mm) — exact match required
• Number of Positions: 100 — exact match required
• Number of Rows: 2 — exact match required
• Row Spacing - Mating: 0.100" (2.54mm) — exact match required
• Connector Type: Header — exact match required
• Contact Type: Male Pin — exact match required
• Mounting Type: Through Hole — exact match required
• Termination: Solder — exact match required
• Shrouding: Unshrouded — exact match required
• Contact Finish - Mating: Gold — exact match required
• Insulation Material: Thermoplastic or Liquid Crystal Polymer — functionally equivalent
• Material Flammability Rating: UL94 V-0 — exact match required
• Moisture Sensitivity Level: 1 (Unlimited) — exact match required

The substitute parts 1-103916-7 and 6-103916-7 (TE Connectivity AMP Connectors, AMPMODU System 50 series) meet all critical substitution criteria. Both parts are manufactured by TE Connectivity, a recognized industry supplier, and maintain compatibility across all essential electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain active product status and meet the core mechanical and electrical requirements for direct substitution with the TMS-150-02-S-D.

6-103916-7 is the preferred substitute option. This part carries ROHS3 compliance matching the original TMS-150-02-S-D specification and maintains all critical connector parameters. The contact finish on the post is tin-plated, consistent with the original design. This part is suitable for applications requiring regulatory compliance alignment with the primary component.

1-103916-7 is an alternative substitute. This part is also manufactured by TE Connectivity with identical core connector specifications. The contact finish on the post is tin-lead plated, which differs from the original tin finish. This part carries "Not applicable" RoHS status, indicating it may not meet RoHS3 compliance requirements. Selection of this part should be based on specific application requirements and regulatory constraints.

Both substitute parts operate within the temperature range of -65°C to 105°C, which encompasses the lower end of the original specification (-55°C to 125°C). Both are rated for 30VAC and maintain UL94 V-0 flammability certification. The insulation material differs (thermoplastic versus liquid crystal polymer), but both materials provide equivalent functional performance in board-to-board header applications.

Frequently Asked Questions (FAQ)

Q: Can 1-103916-7 and 6-103916-7 be used interchangeably with TMS-150-02-S-D?

A: Both parts meet the critical substitution criteria for pitch, position count, row configuration, contact type, mounting method, and termination. The primary difference is RoHS compliance status. 6-103916-7 is ROHS3 compliant, matching the original part. 1-103916-7 carries "Not applicable" RoHS status. Selection depends on application regulatory requirements.

Q: What are the differences in contact dimensions between the main part and substitutes?

A: The TMS-150-02-S-D has a contact length - mating of 0.100" (2.54mm) and contact length - post of 0.120" (3.05mm). Both TE Connectivity substitutes have a contact length - mating of 0.125" (3.18mm) and contact length - post of 0.100" (2.54mm). These dimensional variations are within acceptable tolerance for board-to-board header applications and do not affect functional compatibility.

Q: Are there temperature rating differences between the parts?

A: The TMS-150-02-S-D operates from -55°C to 125°C. Both TE Connectivity substitutes operate from -65°C to 105°C. The substitute parts cover a lower minimum temperature but do not extend to the upper maximum temperature of the original part. Applications requiring operation above 105°C should retain the original TMS-150-02-S-D specification.

Q: What is the difference between tin and tin-lead contact finishes on the post?

A: The TMS-150-02-S-D and 6-103916-7 use tin-plated posts. The 1-103916-7 uses tin-lead plating. Both finishes provide equivalent solder joint reliability in through-hole applications. Tin-lead finishes are not RoHS3 compliant, which is reflected in the 1-103916-7 "Not applicable" RoHS status.

Q: Do the insulation material differences affect performance?

A: The TMS-150-02-S-D uses Liquid Crystal Polymer (LCP) insulation, while both TE Connectivity substitutes use thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements and provide equivalent electrical insulation performance in standard board-to-board header applications.

Q: What inventory levels are available for each part?

A: TMS-150-02-S-D: 902 pieces. 1-103916-7: 1110 pieces. 6-103916-7: 809 pieces. All parts are listed as new original stock.
