3M 7820-0006PR Equivalent & Substitute Parts

Part Overview

The 3M 7820-0006PR is a 20-position ribbon cable DIP header connector with IDC termination, designed for through-hole mounting applications. This connector features a vertical orientation, gray color, and gold-plated contacts suitable for 26 AWG stranded, 28 AWG solid or stranded, and 30 AWG solid wire gauges. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where compatibility is required.

Substitute Part Grouping Explanation

Substitute parts for the 3M 7820-0006PR are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type: Ribbon Cable, DIP Header (identical across all substitutes)
• Number of Positions: 20 positions (fixed requirement)
• Cable Pitch: 0.050" (1.27mm) (ribbon cable standard)
• Board-Side Pitch: 0.100" (2.54mm) (PCB footprint compatibility)
• Number of Rows: 2 rows (mechanical form factor)
• Row Spacing: 0.100" (2.54mm) (board layout compatibility)
• Mounting Type: Through Hole (assembly method)
• Cable Termination: IDC (insulation displacement contact)
• Features: Feed Through (connector design)
• Number of Positions Loaded: All (full population)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental rating)

Substitutes must maintain identical pitch specifications, row configuration, and mounting characteristics to ensure direct compatibility with existing PCB designs and ribbon cable assemblies. Wire gauge compatibility is evaluated within acceptable ranges for IDC termination technology.

Parameter Comparison

Engineering Selection Recommendations

Assmann WSW Components AWLP 20/3,2-G: This substitute maintains full mechanical and electrical compatibility with the 3M 7820-0006PR. The connector shares identical pitch specifications, row configuration, and mounting characteristics. The product is active and ROHS3 compliant, providing long-term availability. The gray color matches the original part, and gold contact finish is preserved. This substitute is the preferred choice for direct replacement in existing designs.

TE Connectivity 1-746610-5: This substitute meets all critical mechanical and pitch requirements for functional compatibility. The connector is active and ROHS3 compliant with established supply chain availability. The contact finish is tin rather than gold, and the color is black instead of gray. These differences do not affect electrical performance in IDC ribbon cable applications but represent a design variation. This substitute is suitable for applications where contact finish and color variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the Assmann AWLP 20/3,2-G be used as a direct replacement for the 3M 7820-0006PR?

A: Yes. The Assmann connector maintains identical pitch specifications (0.050" cable pitch, 0.100" board-side pitch), row configuration (2 rows with 0.100" spacing), and mounting type (through hole). Both connectors use IDC termination and support 20-position ribbon cable assemblies. The gray color and gold contact finish match the original part.

Q: What are the key differences between the TE Connectivity 1-746610-5 and the original 3M part?

A: The TE Connectivity connector differs in contact finish (tin versus gold) and color (black versus gray). All mechanical parameters, pitch specifications, and electrical characteristics remain compatible. The connector supports the same wire gauge range and IDC termination method.

Q: Are there wire gauge compatibility considerations when substituting these connectors?

A: The original 3M 7820-0006PR supports 26 AWG stranded, 28 AWG solid or stranded, and 30 AWG solid wire gauges. The Assmann AWLP 20/3,2-G does not specify wire gauge in the provided data. The TE Connectivity 1-746610-5 supports 26-28 AWG stranded and 26-30 AWG solid wire gauges. Verify ribbon cable specifications match the selected connector's wire gauge rating.

Q: Do these substitutes maintain the same PCB footprint as the original part?

A: Yes. All three connectors share identical board-side pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), and through-hole mounting type. PCB designs using the 3M 7820-0006PR require no modification to accommodate either substitute.

Q: What is the moisture sensitivity level for these connectors?

A: All three connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly.

Q: Are the substitute parts RoHS compliant?

A: The Assmann AWLP 20/3,2-G is ROHS3 compliant. The TE Connectivity 1-746610-5 is ROHS3 compliant. Both substitutes meet current environmental compliance requirements.
