3M 61-S Equivalent & Substitute Parts

Part Overview

The 3M 61-S is a terminal butt splice connector designed for inline, individual openings crimp termination applications. This non-insulated splice terminal accommodates 18-22 AWG wire gauges and is classified as an active product with RoHS compliance. Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across wire gauge, termination method, terminal configuration, and insulation type.

Substitute Part Grouping Explanation

The Panduit Corp BS18-C is identified as a manufacturer-recommended substitute for the 3M 61-S based on the following equivalence criteria:

• Terminal Type: Both are butt splice terminals with inline, individual openings configuration
• Wire Gauge: Both accommodate 18-22 AWG wire
• Termination Method: Both use crimp termination
• Number of Wire Entries: Both feature 2 wire entries
• Insulation: Both are non-insulated terminals
• Product Status: Both are active products
• Regulatory Compliance: Both meet RoHS requirements

These parameters define the functional and mechanical compatibility required for direct substitution in 18-22 AWG crimp splice applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 61-S and Panduit Corp BS18-C are active products meeting RoHS compliance requirements. The Panduit BS18-C carries ROHS3 compliance, representing current regulatory standards. Selection between these parts should be based on availability, supply chain requirements, and any application-specific performance characteristics related to the Panduit Pan-Term® series designation or the 3M manufacturing specification.

Frequently Asked Questions (FAQ)

Q: What makes the Panduit BS18-C a valid substitute for the 3M 61-S?

A: Both terminals share identical electrical and mechanical specifications: 18-22 AWG wire gauge, crimp termination, butt splice configuration with inline individual openings, 2 wire entries, and non-insulated design. These parameters define functional equivalence for splice applications.

Q: Are there differences in terminal construction between these parts?

A: The Panduit BS18-C includes brazed seam and serrated mating area features. These are manufacturing characteristics that do not affect the core substitution criteria of wire gauge, termination method, or terminal configuration.

Q: Can these terminals be used interchangeably in production?

A: Yes, provided the application requirements are limited to the specified wire gauge range (18-22 AWG), crimp termination method, and non-insulated splice configuration. Both parts meet active product status and RoHS compliance.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current version of the RoHS directive. Both compliance levels indicate restriction of hazardous substances; ROHS3 reflects the most recent regulatory framework.

Q: Does packaging affect substitution eligibility?

A: Both parts are supplied in bulk packaging. Substitution is valid at the component level; packaging format does not affect electrical or mechanical compatibility.
