3M 61-SN Terminal Butt Splice Equivalent & Substitute Parts

Part Overview

The 3M 61-SN is an active-status terminal butt splice connector designed for inline wire splicing applications. This fully insulated crimp terminal accommodates 18-22 AWG wire gauges and features individual openings for dual wire entries. The part is RoHS Compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. Equivalent substitute parts are identified based on matching electrical specifications, mechanical compatibility, and termination method to ensure functional interchangeability in splice applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 61-SN is determined by the following critical parameters:

• Terminal Type: Butt Splice, Inline, Individual Openings
• Wire Gauge Range: 18-22 AWG
• Number of Wire Entries: 2
• Termination Method: Crimp
• Insulation Classification: Fully Insulated
• Color: Red

The Panduit Corp BSN18-C meets all substitution criteria. Both parts share identical terminal configuration, wire gauge compatibility, dual-entry design, crimp termination, full insulation, and red color specification. Compliance certifications differ (3M: RoHS Compliant; Panduit: ROHS3 Compliant), with ROHS3 representing an enhanced compliance standard.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 61-SN and Panduit BSN18-C are active-status products with matching electrical and mechanical specifications. Selection between these parts is based on:

• Compliance Requirements: The Panduit BSN18-C carries ROHS3 Compliant certification, which exceeds the RoHS Compliant status of the 3M 61-SN. Applications requiring enhanced RoHS compliance should specify the Panduit part.
• Packaging: The 3M 61-SN is supplied in standard packaging; the Panduit BSN18-C is supplied in bulk packaging, affecting order quantities and logistics.
• Availability: Current inventory shows 909 units of 3M 61-SN and 3,182 units of Panduit BSN18-C in stock.
• Series Designation: The Panduit part belongs to the Pan-Term® series (base product number BSN18).

Both parts satisfy identical functional requirements for 18-22 AWG inline butt splice applications with crimp termination and full insulation.

Frequently Asked Questions (FAQ)

Q: Can the Panduit BSN18-C directly replace the 3M 61-SN in existing designs?

A: Yes. Both parts share identical terminal type, wire gauge range, number of wire entries, termination method, insulation classification, and color. They are functionally interchangeable for inline butt splice applications.

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

A: ROHS3 Compliant represents an updated compliance standard with enhanced requirements. The Panduit BSN18-C meets this higher standard, while the 3M 61-SN meets the baseline RoHS Compliant specification. Both are compliant; ROHS3 is more stringent.

Q: Does packaging affect electrical or mechanical performance?

A: No. The 3M 61-SN standard packaging and Panduit BSN18-C bulk packaging do not affect terminal performance. Packaging selection is based on order quantity requirements and supply chain logistics.

Q: Are both parts suitable for the same wire gauge applications?

A: Yes. Both the 3M 61-SN and Panduit BSN18-C are rated for 18-22 AWG wire gauges and accommodate dual wire entries with crimp termination.

Q: What is the MSL rating significance?

A: The 3M 61-SN carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The Panduit BSN18-C lists MSL as Not Applicable, indicating the part does not require moisture sensitivity classification.
