Key Parameters

Substitute Part Grouping Explanation

Substitution for the 81036-600C04-RB is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 36 positions arranged in 2 rows
• Pitch Specifications: 0.050" (1.27mm) mating pitch with 0.100" (2.54mm) row spacing
• Mounting Technology: Surface mount with solder termination
• Shrouding Design: 4-wall shrouded construction with push-pull fastening
• Contact Materials & Finishes: Gold-plated mating contacts, tin-plated posts
• Insulation Material: Liquid Crystal Polymer (LCP)
• Electrical & Environmental Ratings: 0.75A current rating, -55°C to 105°C operating range, UL94 V-0 flammability compliance

Only components matching all these parameters across the rectangular connector category qualify as direct substitutes. The obsolete status of this part necessitates sourcing alternatives that maintain identical mechanical and electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 81036-600C04-RB is classified as obsolete. When sourcing replacements, prioritize components that maintain identical specifications across all mechanical and electrical parameters listed in the Key Parameters section.

The recommended part 81036-600C04-RB matches the original specification completely. Both the main part and recommended substitute carry RoHS compliance certification and UL94 V-0 flammability rating, meeting regulatory requirements for industrial and commercial applications.

For applications requiring this connector type, verify that the substitute part maintains compatibility with existing PCB footprints, mating connector designs, and assembly processes. The surface mount configuration and solder termination method must align with current manufacturing capabilities.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the 81036-600C04-RB?

A: A valid substitute must match all critical parameters: 36-position, 2-row configuration with 0.050" (1.27mm) pitch, surface mount technology, shrouded 4-wall design, push-pull fastening, gold-plated mating contacts, tin-plated posts, LCP insulation material, 0.75A current rating, and -55°C to 105°C operating temperature range.

Q: Why is the 81036-600C04-RB listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by 3M. This designation requires identification of functionally equivalent alternatives for ongoing design support and component procurement.

Q: Are there compatibility concerns when substituting this connector?

A: Substitutes must maintain identical pitch spacing (0.050"), row spacing (0.100"), and shrouding configuration to ensure mechanical compatibility with mating connectors and PCB footprints. Contact finish specifications (gold mating, tin post) must also be preserved to maintain electrical performance and reliability.

Q: What certifications should I verify for a substitute part?

A: Confirm RoHS compliance status and UL94 V-0 flammability rating match the original specification. These certifications are essential for regulatory compliance in most industrial and commercial applications.

Q: Does the MSL rating affect substitution decisions?

A: The MSL 1 (Unlimited) rating indicates no moisture sensitivity constraints during storage or handling. Substitute parts should maintain this same MSL classification to avoid additional moisture control requirements in manufacturing processes.
