TMS-120-02-S-D Equivalent & Substitute Parts

Part Overview

The TMS-120-02-S-D is a 0.050" (1.27mm) pitch micro header connector manufactured by Samtec Inc., designed for board-to-board applications requiring through-hole solder termination. This 40-position, 2-row unshrouded header operates across -55°C to 125°C and is classified as Active product status with full RoHS3 compliance. Equivalent parts are identified when they maintain critical electrical and mechanical parameters including pitch, position count, row configuration, contact material properties, and termination method.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS-120-02-S-D is determined by strict equivalence across the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm) — exact match required
• Number of Positions: 40 — 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
• Fastening Type: Push-Pull — exact match required
• Contact Finish - Mating: Gold — exact match required
• Material Flammability Rating: UL94 V-0 — exact match required

The substitute part 1-103916-1 (TE Connectivity AMP Connectors) meets all critical mechanical and electrical parameters for direct substitution in applications where the TMS-120-02-S-D is specified.

Parameter Comparison

Engineering Selection Recommendations

The TMS-120-02-S-D is the primary selection for new designs and applications requiring RoHS3 compliance. The part is Active status with full regulatory compliance and operates across an extended temperature range of -55°C to 125°C.

The 1-103916-1 substitute part is mechanically and electrically compatible for direct replacement in existing applications. However, the following compliance differences must be evaluated:

• The 1-103916-1 is RoHS non-compliant and REACH-affected, making it unsuitable for applications subject to RoHS3 or REACH regulatory requirements.
• The TMS-120-02-S-D operates to -55°C minimum temperature, while the 1-103916-1 operates to -65°C minimum, providing extended low-temperature capability in the substitute.
• The TMS-120-02-S-D operates to 125°C maximum temperature, while the 1-103916-1 operates to 105°C maximum, providing extended high-temperature capability in the primary part.

For applications requiring RoHS3 compliance, the TMS-120-02-S-D is the required selection. For legacy systems or applications without regulatory compliance requirements, the 1-103916-1 provides mechanical and electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 1-103916-1 be used as a direct replacement for the TMS-120-02-S-D in new designs?

A: The 1-103916-1 is mechanically and electrically compatible for direct replacement. However, if the application requires RoHS3 compliance, the TMS-120-02-S-D must be used, as the 1-103916-1 is RoHS non-compliant.

Q: What are the key parameters that determine substitution compatibility?

A: Pitch (0.050"), position count (40), row configuration (2 rows), row spacing (0.100"), connector type (Header), contact type (Male Pin), mounting type (Through Hole), termination method (Solder), fastening type (Push-Pull), contact finish (Gold), and flammability rating (UL94 V-0) must all match exactly.

Q: Are there differences in operating temperature ranges between these parts?

A: Yes. The TMS-120-02-S-D operates from -55°C to 125°C, while the 1-103916-1 operates from -65°C to 105°C. Applications requiring operation above 105°C or below -55°C must use the TMS-120-02-S-D.

Q: What is the difference in insulation material between these connectors?

A: The TMS-120-02-S-D uses Liquid Crystal Polymer (LCP), while the 1-103916-1 uses Thermoplastic. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified applications.

Q: Does the 1-103916-1 have a voltage rating specification?

A: Yes, the 1-103916-1 is rated for 30VAC. The TMS-120-02-S-D voltage rating is not specified in the provided data.

Q: Are both parts available in the same packaging?

A: Yes, both parts are supplied in Tube packaging and have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.
