MVU14BCK Equivalent & Substitute Parts

Part Overview

The MVU14BCK is a terminal butt splice connector manufactured by 3M, designed for inline, individual openings crimp termination of 14-16 AWG wire gauges. This fully insulated connector is part of the Scotchlok™ series and maintains active product status. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or application-specific packaging needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for MVU14BCK is determined by strict equivalence across the following parameters: terminal type (butt splice, inline, individual openings), wire gauge range (14-16 AWG), number of wire entries (2), termination method (crimp), insulation classification (fully insulated), and color (blue). All identified substitutes meet these core electrical and mechanical requirements. Packaging format and manufacturer-specific features (such as serrated mating area or brazed seam construction) do not affect functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three connectors—MVU14BCK, 2-34071-1, and BSV14X-M—are active products with equivalent electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and compliance certifications. The MVU14BCK and BSV14X-M are supplied in bulk packaging, while the 2-34071-1 is available in cut tape format. All parts maintain REACH unaffected status and EAR99 export classification. RoHS compliance is confirmed across all options, with MVU14BCK meeting RoHS standard and both substitute parts meeting ROHS3 requirements.

Frequently Asked Questions (FAQ)

Q: Can MVU14BCK be directly replaced with 2-34071-1 or BSV14X-M? A: Yes. All three connectors share identical terminal type, wire gauge, wire entry count, termination method, insulation classification, and color. Functional interchangeability is confirmed within the specified electrical and mechanical parameters.

Q: Does packaging format affect substitution eligibility? A: No. Packaging format (bulk versus cut tape) does not affect electrical or mechanical compatibility. Selection should be based on assembly process requirements and inventory management practices.

Q: Are there compliance differences between the three parts? A: All parts are REACH unaffected and EAR99 classified. RoHS compliance is confirmed across all options. The MVU14BCK meets RoHS standard, while 2-34071-1 and BSV14X-M meet ROHS3 requirements.

Q: What distinguishes the manufacturer-specific features? A: The 2-34071-1 includes a serrated mating area feature, while the BSV14X-M features brazed seam construction. These design variations do not affect substitution eligibility based on the core electrical and mechanical parameters.

Q: Which part should be selected for new designs? A: Selection should be based on packaging availability, supply chain considerations, and manufacturer preference. All three parts meet identical functional requirements for 14-16 AWG crimp butt splice applications.
