3M 61 Terminal Butt Splice Equivalent & Substitute Parts

Part Overview

The 3M 61 is an active, RoHS-compliant terminal butt splice connector designed for inline, individual opening applications. This non-insulated crimp terminal accommodates 18-22 AWG wire gauges with a butted seam construction. As an active product with established inventory availability, equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and application-specific requirements where alternative seam construction or feature sets may be beneficial.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 61 is determined by strict equivalence across the following critical parameters:

• Terminal Type: Butt Splice, Inline, Individual Openings
• Number of Wire Entries: 2
• Termination Method: Crimp
• Wire Gauge Range: 18-22 AWG
• Insulation: Non-Insulated
• Product Status: Active

The Panduit Corp BS18-C meets all mandatory substitution criteria. While the BS18-C features a brazed seam with serrated mating area (compared to the 3M 61's butted seam), these construction differences do not affect functional compatibility within the specified wire gauge and termination parameters. Both parts are active products with RoHS compliance certifications appropriate to their respective manufacturing standards.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 61 and Panduit Corp BS18-C are active products with current manufacturing status and appropriate RoHS compliance certifications. Selection between these parts should be based on:

• Availability and lead time requirements
• Seam construction preference (butted versus brazed)
• Mating area feature requirements (serrated mating area in BS18-C)
• Established supplier relationships and procurement channels
• Application-specific performance validation if seam construction differences are critical to end-use performance

Frequently Asked Questions (FAQ)

Q: Can the Panduit Corp BS18-C directly replace the 3M 61 in existing designs?

A: Yes. Both terminals meet the core functional requirements: 2-wire butt splice configuration, 18-22 AWG wire gauge capacity, crimp termination, and non-insulated construction. The brazed seam and serrated mating area of the BS18-C represent construction enhancements rather than compatibility barriers.

Q: What is the difference between butted seam and brazed seam construction?

A: Butted seam (3M 61) and brazed seam (Panduit BS18-C) are different manufacturing methods for joining terminal halves. Both achieve functional splice capability within the specified wire gauge range. Brazed seam construction may offer enhanced durability in certain vibration or thermal cycling environments.

Q: Are both parts RoHS compliant?

A: Yes. The 3M 61 is RoHS Compliant. The Panduit Corp BS18-C is ROHS3 Compliant. Both meet applicable RoHS directives for their respective manufacturing jurisdictions.

Q: What packaging options are available?

A: Both parts are supplied in bulk packaging. Inventory availability: 3M 61 (627 Pcs), Panduit Corp BS18-C (13,188 Pcs).

Q: Are there any wire gauge limitations when substituting between these parts?

A: No. Both parts support identical wire gauge specifications: 18-22 AWG. Substitution does not introduce wire gauge constraints.
