MC4/0BCX Equivalent & Substitute Parts

Part Overview

The MC4/0BCX is a terminal butt splice connector manufactured by 3M, designed for inline, individual openings crimp termination of 4/0 AWG wire. This non-insulated purple splice terminal is part of the Scotchlok™ series and is currently classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for maintaining system compatibility and ensuring continued availability for repair and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MC4/0BCX is determined by strict equivalence across the following critical parameters:

• Terminal Type: Butt Splice, Inline, Individual Openings
• Wire Gauge: 4/0 AWG
• Number of Wire Entries: 2
• Termination Method: Crimp
• Insulation: Non-Insulated
• Color: Purple

The substitute part SCS4/0-X manufactured by Panduit Corp matches all these parameters, establishing functional equivalence for direct replacement applications. Both parts are designed for the same wire gauge range, employ identical crimp termination methodology, and maintain the same connector configuration.

Parameter Comparison

Engineering Selection Recommendations

The SCS4/0-X from Panduit Corp is the designated substitute for the obsolete MC4/0BCX. This substitution is supported by:

• Functional Equivalence: Identical terminal type, wire gauge, wire entry configuration, and crimp termination methodology
• Active Product Status: The SCS4/0-X is currently in active production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts meet EAR99 export classification and share identical HTSUS commodity codes. The SCS4/0-X carries ROHS3 compliance, exceeding the RoHS compliance of the original part
• Electrical and Mechanical Compatibility: Matching specifications across all critical parameters ensure direct functional replacement without system redesign

Frequently Asked Questions (FAQ)

Q: Can the SCS4/0-X directly replace the MC4/0BCX in existing applications?

A: Yes. Both parts are functionally equivalent across all critical parameters: terminal type, wire gauge (4/0 AWG), wire entry configuration (2 entries), crimp termination, non-insulated construction, and purple color. Direct substitution is appropriate for repair and replacement applications.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The MC4/0BCX is obsolete and no longer manufactured by 3M. The SCS4/0-X is actively produced by Panduit Corp, ensuring reliable availability for future procurement and system maintenance.

Q: Are there compliance differences between these parts?

A: Both parts comply with export regulations (EAR99) and share the same HTSUS classification. The SCS4/0-X carries ROHS3 compliance, which represents an enhanced regulatory standard compared to the RoHS compliance of the original part.

Q: Does packaging differ between these parts?

A: The MC4/0BCX is supplied in standard packaging, while the SCS4/0-X is supplied in bulk packaging. This difference does not affect functional compatibility but may influence procurement quantities and handling procedures.

Q: Are there any wire gauge or termination method differences?

A: No. Both parts are specified for 4/0 AWG wire and employ crimp termination methodology. The connector configuration and wire entry design are identical.
