Key Parameters

Substitute Part Grouping Explanation

Substitution for the 3M 961104-6700-AR-TP is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — mechanical compatibility requirement
• Number of Positions: 4 — functional requirement
• Number of Rows: 1 — physical layout requirement
• Connector Type: Header — functional classification
• Contact Type: Male Pin — mating interface requirement
• Mounting Type: Surface Mount — assembly process requirement
• Termination: Solder — connection method requirement
• Material Flammability Rating: UL94 V-0 — safety compliance requirement
• Moisture Sensitivity Level: 1 (Unlimited) — handling and storage requirement

All substitute parts listed maintain these core parameters, ensuring direct functional and mechanical compatibility with the original 3M component.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status, ensuring long-term availability and manufacturing support. The Molex 0878980466, Harwin M20-8770442R, and Samtec TSM-104-02-T-SV are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The Harwin M20-8770442R offers the widest operating temperature range (-40°C ~ 105°C) and highest current rating (3A per contact), providing additional performance margin for demanding applications. The Samtec TSM-104-02-T-SV extends the lower temperature limit to -55°C, suitable for extended environmental conditions. The Molex 0878980466 provides the most direct functional equivalence with board-to-board or cable style flexibility.

All substitute parts maintain the critical 0.100" (2.54mm) pitch, 4-position, single-row configuration and UL94 V-0 flammability rating required for direct replacement.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0878980466 directly replace the 3M 961104-6700-AR-TP?

A: Yes. Both connectors share the same pitch (0.100" / 2.54mm), position count (4), row configuration (1), mounting type (surface mount), termination method (solder), and flammability rating (UL94 V-0). The Molex part offers breakaway functionality as an additional feature.

Q: What is the difference between the contact length specifications?

A: The 3M part specifies 0.260" (6.60mm) mating contact length, while the Molex and Samtec parts specify 0.320" (8.13mm), and the Harwin part specifies 0.228" (5.80mm). These variations affect mating depth and may require PCB layout verification for optimal engagement.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0878980466, Harwin M20-8770442R, and Samtec TSM-104-02-T-SV are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Which substitute part offers the best temperature performance?

A: The Samtec TSM-104-02-T-SV provides the widest operating temperature range (-55°C ~ 105°C), followed by the Harwin M20-8770442R (-40°C ~ 105°C). The original 3M part operates from -25°C ~ 105°C.

Q: What packaging options are available for the substitute parts?

A: The Molex 0878980466 is supplied in Tube packaging. The Harwin M20-8770442R is supplied in Tape & Reel (TR) format. The Samtec TSM-104-02-T-SV is supplied in Tube packaging.

Q: Can these connectors be used for cable applications?

A: The Molex 0878980466, Harwin M20-8770442R, and Samtec TSM-104-02-T-SV all support board-to-board or cable style configurations. The original 3M part is specified for board-to-board style only.
