3M 7860-0006PR Equivalent & Substitute Parts

Part Overview

The 3M 7860-0006PR is a 60-position ribbon cable DIP header connector with IDC termination, designed for through-hole mounting applications. This connector features a vertical orientation with 0.050" cable pitch and 0.100" board-side pitch, supporting wire gauges from 26 AWG to 30 AWG. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3M 7860-0006PR are qualified based on the following critical parameters that must match or be compatible:

• Number of positions: 60
• Cable pitch: 0.050" (1.27mm)
• Board-side pitch: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing: 0.100" (2.54mm)
• Mounting type: Through Hole
• Cable termination: IDC
• Features: Feed Through
• Connector type: Ribbon Cable, DIP Header

The identified substitute parts maintain these core electrical and mechanical parameters, ensuring functional compatibility in applications originally designed for the 3M 7860-0006PR. Variations in color, contact finish material, and wire gauge specifications are acceptable within the scope of substitution, provided the connector maintains the same pitch geometry and termination method.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status, ensuring long-term availability and supply chain stability compared to the obsolete 3M 7860-0006PR.

The Assmann WSW Components AWLP 60/3,2-G provides the closest physical and electrical match, retaining the gray color and gold contact finish of the original part while offering ROHS3 compliance and unlimited moisture sensitivity rating.

The TE Connectivity 2-746610-4 offers an alternative with tin contact finish and black color. This part is supplied in bulk packaging and carries ROHS3 compliance certification. The wire gauge specification supports 26-28 AWG stranded and 26-30 AWG solid conductors, providing broader wire gauge compatibility than the original specification.

Both substitute parts are qualified for direct replacement based on matching connector geometry, pitch specifications, mounting method, and IDC termination technology.

Frequently Asked Questions (FAQ)

Q: Can the Assmann AWLP 60/3,2-G directly replace the 3M 7860-0006PR?

A: Yes. Both connectors share identical pitch geometry (0.050" cable pitch, 0.100" board-side pitch), 60-position configuration, through-hole mounting, and IDC termination. The gray color and gold contact finish of the Assmann part match the original specification.

Q: What are the differences between the TE Connectivity 2-746610-4 and the original 3M part?

A: The TE Connectivity part differs in contact finish (tin versus gold) and color (black versus gray). The connector maintains identical pitch geometry, position count, and termination method. Wire gauge support is broader, accommodating 26-30 AWG solid conductors compared to the original 30 AWG solid specification.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the Assmann AWLP 60/3,2-G and TE Connectivity 2-746610-4 are ROHS3 compliant. The original 3M 7860-0006PR RoHS status is not specified.

Q: What is the significance of the 0.050" cable pitch and 0.100" board-side pitch?

A: These pitch specifications define the physical spacing of the connector contacts and determine compatibility with ribbon cables and PCB footprints. Substitute parts must maintain these exact pitch values to ensure mechanical and electrical compatibility.

Q: Can wire gauge be mixed between the original part and substitutes?

A: Wire gauge compatibility is determined by the IDC termination mechanism. The original part supports 26 AWG stranded, 28 AWG solid or stranded, and 30 AWG solid. The TE Connectivity substitute supports 26-28 AWG stranded and 26-30 AWG solid. Verify wire gauge compatibility with your specific application requirements.

Q: What does "Feed Through" feature mean?

A: Feed Through indicates that the connector allows ribbon cable to pass through the connector body, enabling daisy-chain or multi-point connection configurations in ribbon cable applications.
