3M 81026-600C01-RB Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 81026-600C01-RB is a surface mount rectangular connector header designed for board-to-cable/wire applications. This 26-position, 2-row header operates at 0.050" (1.27mm) pitch with shrouded 4-wall construction and push-pull fastening. The connector is rated for 0.75A per contact and operates across -55°C to 105°C. The part is currently in active production status with 951 pieces available in inventory.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when design revisions require alternative sourcing options, or when supply chain optimization requires qualified alternatives that maintain identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 81026-600C01-RB is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Row Configuration: 26 positions arranged in 2 rows
• Pitch Specifications: 0.050" (1.27mm) mating pitch with 0.100" (2.54mm) row spacing
• Mounting Technology: Surface mount termination with solder connection
• Mechanical Interface: Shrouded 4-wall construction with push-pull fastening
• Electrical Performance: 0.75A current rating per contact
• Environmental Compliance: UL94 V-0 flammability rating and operating range of -55°C to 105°C
• Material Composition: Liquid Crystal Polymer insulation with copper alloy contacts

Only parts matching all these parameters across connector architecture, electrical specifications, and environmental ratings qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 81026-600C01-RB (obsolete status) maintains complete electrical and mechanical equivalence to the active production version. Both variants are manufactured by 3M within the 810 series and share identical specifications across all critical parameters including connector architecture, pitch configuration, current rating, and operating temperature range.

The active production part (81026-600C01-RB) is the preferred selection for new designs and ongoing production due to its active product status and assured long-term availability. The obsolete variant remains electrically and mechanically compatible for legacy system support or when existing inventory is available.

Both parts carry UL94 V-0 flammability certification and are suitable for applications requiring -55°C to 105°C operation. The substitute part includes additional compliance documentation: RoHS Compliant status, Moisture Sensitivity Level (MSL) 1 (Unlimited), ECCN EAR99, and HTSUS 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can the obsolete 81026-600C01-RB be used as a direct replacement for the active production version?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The obsolete variant maintains the same 26-position, 2-row configuration, 0.050" pitch, surface mount construction, and 0.75A current rating. Selection between them depends on inventory availability and supply chain requirements rather than technical compatibility.

Q: What parameters must remain constant for substitution eligibility?

A: Direct substitution requires equivalence in connector type (header), contact configuration (male pin, 26 positions, 2 rows), pitch specifications (0.050" mating, 0.100" row spacing), mounting technology (surface mount), shrouding design (4-wall), fastening mechanism (push-pull), current rating (0.75A), operating temperature range (-55°C to 105°C), and insulation material (LCP).

Q: Are there differences in compliance or certification between the two parts?

A: Both parts meet UL94 V-0 flammability requirements and operate across -55°C to 105°C. The substitute part documentation includes RoHS Compliant status, MSL 1 (Unlimited), ECCN EAR99, and HTSUS classification. These certifications apply to the substitute variant and should be verified against specific application requirements.

Q: What is the current inventory status for each part?

A: The active production 81026-600C01-RB has 951 pieces in stock. The obsolete variant has 875 pieces available. Inventory levels are subject to change and should be confirmed at time of procurement.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both parts share identical footprints, pitch specifications, and mechanical dimensions. No PCB layout modifications are required when substituting between the active and obsolete variants of the 81026-600C01-RB.
