TSM-105-02-L-DV-LC Equivalent & Substitute Parts

Part Overview

The TSM-105-02-L-DV-LC is a surface mount rectangular connector header manufactured by Samtec Inc. in the TSM series. This 10-position, 2-row connector with 0.100" (2.54mm) pitch is designed for board-to-board or cable applications with push-pull fastening and solder termination. The part is currently active in production. Equivalent and substitute parts may be required due to supply chain considerations, packaging preferences, or design revision requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-105-02-L-DV-LC is determined by the following critical parameters that must match or be compatible:

Mandatory Matching Parameters:

• Number of Positions: 10
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Length - Mating: 0.320" (8.13mm)
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0

Allowable Variations:

• Connector Type: Header variants (Cuttable, Breakaway)
• Contact Material: Phosphor Bronze or Copper Alloy
• Contact Finish - Mating: Gold (with thickness variations)
• Operating Temperature Range: Equal or extended range
• Packaging: Tube or Bulk
• Product Status: Active or Obsolete (with compliance verification)
• RoHS Status: ROHS3 Compliant or RoHS Compliant

The substitute parts 146131-4 and 5-146131-4 from TE Connectivity AMP Connectors meet these criteria and are electrically and mechanically compatible with the TSM-105-02-L-DV-LC.

Parameter Comparison

Engineering Selection Recommendations

TSM-105-02-L-DV-LC (Primary Selection)

The TSM-105-02-L-DV-LC is the recommended primary choice for new designs. It is currently active in production, ROHS3 compliant, and available in tube packaging. The part offers a 0.100" (2.54mm) insulation height and phosphor bronze contact material with 10.0µin gold plating.

5-146131-4 (Preferred Substitute)

The 5-146131-4 is the preferred substitute option. It is active in production, ROHS3 compliant, and available in tube packaging matching the primary part's packaging format. This part is electrically and mechanically compatible with identical pitch, row spacing, contact length, and mating dimensions. The extended operating temperature range (-65°C ~ 125°C) provides additional thermal margin. The 0.090" (2.29mm) insulation height and copper alloy contact material with 30.0µin gold plating represent acceptable variations within the connector class.

146131-4 (Secondary Substitute)

The 146131-4 is a secondary substitute option. While electrically and mechanically compatible, this part is obsolete and available only in bulk packaging. Selection of this part should be limited to legacy system support or when bulk quantities are specifically required. RoHS compliance status is standard RoHS rather than ROHS3.

Frequently Asked Questions (FAQ)

Q: Can the 5-146131-4 be used as a direct replacement for the TSM-105-02-L-DV-LC in new designs?

A: Yes. The 5-146131-4 meets all mandatory electrical and mechanical parameters. Both parts share identical pitch (0.100"), row spacing (0.100"), contact length (0.320"), number of positions (10), and number of rows (2). Both are surface mount, solder-terminated headers with push-pull fastening and UL94 V-0 rated LCP insulation. The 5-146131-4 is active in production and ROHS3 compliant.

Q: What is the difference between the 146131-4 and 5-146131-4?

A: The primary differences are product status and packaging. The 146131-4 is obsolete and supplied in bulk packaging, while the 5-146131-4 is active in production and supplied in tube packaging. Both are electrically and mechanically identical. For new designs, the 5-146131-4 is preferred due to active production status.

Q: Are there any compatibility concerns with the insulation height difference (0.100" vs 0.090")?

A: No. The insulation height difference does not affect electrical or mechanical compatibility. Both dimensions are within acceptable tolerances for the 0.100" (2.54mm) pitch connector class. The mating interface and contact engagement remain identical.

Q: Does the contact material difference (Phosphor Bronze vs Copper Alloy) affect performance?

A: No. Both phosphor bronze and copper alloy are standard contact materials for this connector class. Both materials provide equivalent electrical conductivity and mechanical durability. The gold plating on both parts ensures reliable mating surface contact.

Q: What is the significance of the gold plating thickness difference (10.0µin vs 30.0µin)?

A: Both plating thicknesses meet industry standards for connector reliability. The 30.0µin thickness on the substitute parts provides additional corrosion resistance margin. This represents an enhancement rather than a limitation for long-term reliability.

Q: Can the 146131-4 be used in new production?

A: The 146131-4 is obsolete and should not be selected for new designs. It is suitable only for legacy system support or repair applications where the original part number must be maintained. For new production, use either the TSM-105-02-L-DV-LC or the 5-146131-4.

Q: Are there any RoHS compliance differences between these parts?

A: The TSM-105-02-L-DV-LC and 5-146131-4 are both ROHS3 compliant. The 146131-4 is RoHS compliant but not ROHS3 certified. For applications requiring ROHS3 compliance, use the TSM-105-02-L-DV-LC or 5-146131-4.

Q: What is the operating temperature range difference?

A: The TSM-105-02-L-DV-LC operates from -55°C to 125°C, while both TE Connectivity parts operate from -65°C to 125°C. The extended lower temperature limit on the substitute parts provides additional thermal margin for cold environment applications.
