Key Parameters

Substitute Part Grouping Explanation

The Samtec Inc. TSM-109-01-L-DV qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Header with male pin contacts
• Position count and arrangement: 18 positions in 2 rows
• Pitch specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting method: Surface mount with solder termination
• Contact finish: Gold-plated mating surfaces with tin-plated posts
• Shrouding: Unshrouded configuration
• Fastening type: Push-Pull
• Style: Board to Board or Cable (compatible with Board to Board applications)
• Flammability rating: UL94 V-0
• Moisture sensitivity: MSL 1 (Unlimited)

Allowable Variations:

• Contact material: Phosphor Bronze (substitute) vs. Copper Alloy (original) — both materials provide equivalent electrical and mechanical performance in this application class
• Insulation material: Liquid Crystal Polymer (LCP) (substitute) vs. Thermoplastic (original) — both meet UL94 V-0 requirements
• Operating temperature range: -55°C ~ 125°C (substitute) vs. -25°C ~ 105°C (original) — substitute provides extended range
• Contact length - mating: 0.230" (5.84mm) (substitute) vs. 0.260" (6.60mm) (original) — minor variation within acceptable tolerance for this connector class
• Contact finish thickness - mating: 10.0µin (0.25µm) (substitute) vs. Flash (original) — both provide adequate contact durability

Parameter Comparison

Engineering Selection Recommendations

The Samtec TSM-109-01-L-DV is the designated substitute for the obsolete 3M 961218-6700-AR-TP. Selection is based on:

Product Status: The original part is obsolete, while the substitute is active and in production, ensuring long-term availability and supply chain continuity.

Compliance and Certifications: Both parts meet UL94 V-0 flammability requirements. The substitute additionally carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in regulated markets.

Electrical and Mechanical Compatibility: The substitute maintains identical pitch, position count, row configuration, and contact type specifications. Both parts support 2A current ratings and feature gold-plated mating contacts with tin-plated posts.

Environmental Performance: The substitute's extended operating temperature range (-55°C ~ 125°C) provides additional margin beyond the original specification (-25°C ~ 105°C), supporting applications across broader thermal environments.

Material Specifications: Phosphor Bronze contacts and Liquid Crystal Polymer insulation in the substitute provide equivalent or superior performance characteristics compared to the original Copper Alloy and Thermoplastic materials, with both meeting the same flammability classification.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TSM-109-01-L-DV be used as a direct replacement for the 3M 961218-6700-AR-TP?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), position count (18 in 2 rows), contact type (male pin), mounting method (surface mount), and termination type (solder). The substitute is rated for equivalent or extended operating conditions.

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

A: The primary differences are contact material (Phosphor Bronze vs. Copper Alloy), insulation material (LCP vs. Thermoplastic), operating temperature range (-55°C ~ 125°C vs. -25°C ~ 105°C), and contact length at mating interface (0.230" vs. 0.260"). All differences fall within acceptable substitution parameters for this connector class.

Q: Does the Samtec part have any additional features?

A: The Samtec TSM-109-01-L-DV is specified as cuttable, allowing customization of position count if required. The original 3M part does not carry this designation. Additionally, the Samtec part is ROHS3 compliant and REACH unaffected, meeting current regulatory standards.

Q: Are there packaging differences between the original and substitute?

A: The original 3M part packaging is not specified in available documentation. The Samtec substitute is supplied in tube packaging. Confirm packaging requirements with your procurement department.

Q: What is the moisture sensitivity level for both parts?

A: Both the 3M 961218-6700-AR-TP and Samtec TSM-109-01-L-DV are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts suitable for the same PCB assembly processes?

A: Yes. Both parts are surface mount connectors with solder termination, compatible with standard reflow soldering processes. The similar contact geometry and pitch specifications ensure equivalent assembly handling.
