3M 82040-6006RB Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The 3M 82040-6006RB is a 40-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector features gold-plated female socket contacts rated for 30 AWG wire and includes feed-through and strain relief characteristics. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 3M 82040-6006RB rectangular connector is determined by the following critical parameters:

• 40-position contact count with 2-row configuration
• 0.050" (1.27mm) contact pitch and 0.100" (2.54mm) row spacing
• IDC termination method for ribbon cable
• 30 AWG wire gauge specification
• Gold contact finish with 30.0µin thickness
• Female socket contact type
• Free hanging in-line mounting orientation
• Feed-through and strain relief features

Any substitute part must maintain identical values across all these parameters to ensure mechanical fit, electrical performance, and functional compatibility within the host system.

Parameter Comparison

Engineering Selection Recommendations

The 3M 82040-6006RB is ROHS3 compliant and carries an MSL rating of 1 (unlimited moisture sensitivity), indicating suitability for standard industrial and commercial applications without special storage or handling requirements. The connector meets REACH compliance standards and is classified under ECCN EAR99 for export purposes.

Given the obsolete product status, component sourcing should prioritize parts with identical electrical and mechanical specifications. The substitute part listed maintains full parameter equivalence, ensuring direct compatibility in existing designs without circuit modification or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the 3M 82040-6006RB be replaced with a different pitch connector? A: No. The 0.050" (1.27mm) pitch is a critical mechanical parameter. Substitutes must maintain this exact pitch to ensure proper mating with corresponding plug connectors and ribbon cable termination.

Q: Are there compatibility concerns with the IDC termination method? A: The IDC termination is integral to this connector design. Substitutes must support IDC termination for 30 AWG ribbon cable. Connectors using different termination methods (solder, crimp) are not compatible.

Q: Does the gold contact finish affect substitution eligibility? A: Yes. The 30.0µin (0.76µm) gold plating thickness is specified for electrical performance and corrosion resistance. Substitutes must match this finish specification exactly.

Q: What is the significance of the 2-row, 40-position configuration? A: This configuration determines the connector's footprint and mating interface. Any substitute must maintain the identical 2-row layout with 0.100" (2.54mm) row spacing and 40 total contact positions.

Q: Is the free-hanging in-line mounting type critical for substitution? A: Yes. The mounting orientation affects installation method and mechanical integration. Substitutes must support the same free-hanging in-line configuration.

Q: Does ROHS3 compliance impact substitute selection? A: ROHS3 compliance is a regulatory requirement for this product category. Substitutes must maintain equivalent or superior compliance status to meet current environmental standards.
