3M 81020-600C01-RB Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 81020-600C01-RB is a surface mount rectangular connector header designed for board-to-cable/wire applications. This connector features 20 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing and incorporates shrouded 4-wall design with push-pull fastening. The part is currently in Active product status with 678 pieces available in inventory.

The 81020-600C01-RB serves as the primary reference for identifying compatible substitute components. Substitute parts must maintain electrical and mechanical compatibility across critical parameters including pitch, position count, row configuration, mounting type, and contact specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute compatibility for the 3M 81020-600C01-RB is determined by strict adherence to the following critical parameters:

Electrical Parameters:

• Contact pitch: 0.050" (1.27mm)
• Row spacing: 0.100" (2.54mm)
• Current rating: 0.75A
• Operating temperature range: -55°C ~ 105°C
• Contact material: Copper Alloy

Mechanical Parameters:

• Position count: 20 positions
• Row configuration: 2 rows
• Connector type: Header
• Contact type: Male Pin
• Mounting type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Push-Pull

Material & Compliance Parameters:

• Insulation material: Liquid Crystal Polymer (LCP)
• Material flammability rating: UL94 V-0
• Contact finish - Mating: Gold
• Contact finish - Post: Tin

Parts meeting all specified parameters are classified as direct substitutes. Deviations in any critical parameter disqualify a component from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

The 81020-600C01-RB substitute part maintains complete electrical and mechanical compatibility with the main part specification. Both components are manufactured by 3M within the 810 series and share identical critical parameters across pitch, position count, row configuration, mounting type, and contact specifications.

The primary distinction between the main part and substitute is product status: the main part is Active, while the substitute is Obsolete. The substitute part carries RoHS Compliance certification, Moisture Sensitivity Level (MSL) 1 (Unlimited), ECCN EAR99, and HTSUS 8536.69.4040 classification.

Selection between these parts should be based on availability requirements and product lifecycle considerations. The Active status of the main part (81020-600C01-RB) supports long-term supply continuity for new designs. The Obsolete status of the substitute indicates limited future availability and is suitable only for legacy system maintenance or replacement applications where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the 81020-600C01-RB?

A: Substitute parts must match all critical parameters: 20 positions in 2 rows, 0.050" (1.27mm) pitch, 0.100" (2.54mm) row spacing, surface mount configuration, shrouded 4-wall design, push-pull fastening, solder termination, copper alloy contacts, LCP insulation, 0.75A current rating, -55°C to 105°C operating temperature, and UL94 V-0 flammability rating.

Q: Are there differences in contact finish specifications?

A: Both the main part and substitute maintain identical contact finish specifications: gold plating on mating contacts (30.0µin / 0.76µm thickness) and tin plating on posts (250.0µin / 6.35µm thickness).

Q: What is the significance of the Obsolete product status?

A: Obsolete status indicates the substitute part is no longer in active production. While electrically and mechanically compatible, future availability cannot be guaranteed. The Active status of the main part ensures continued supply for ongoing production requirements.

Q: Can the substitute part be used in new designs?

A: The substitute part is electrically and mechanically equivalent but carries Obsolete status. New designs should specify the Active part (81020-600C01-RB) to ensure long-term component availability and supply chain continuity.

Q: What compliance certifications apply to the substitute part?

A: The substitute part is RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), classified under ECCN EAR99 and HTSUS 8536.69.4040.
