3M 10003 Terminal Butt Splice 2 AWG Crimp - Equivalent & Substitute Parts

Part Overview

The 3M 10003 is an active-status terminal butt splice connector designed for inline, individual opening crimp termination of 2 AWG copper wire. This non-insulated splice terminal is part of the Scotchlok™ series and is commonly used in electrical interconnection applications requiring reliable butt splice connections. Substitute parts may be necessary due to inventory availability, supply chain considerations, or specific procurement requirements while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 10003 is determined by strict equivalence across the following critical parameters:

• Terminal Type: Butt Splice, Inline, Individual Openings
• Wire Gauge: 2 AWG
• Termination Method: Crimp
• Insulation: Non-Insulated
• Wire Material: Copper Wire Only
• Color: Brown
• Number of Wire Entries: 2

The substitute part SCS2-Q (Panduit Corp) meets all these criteria, establishing functional and mechanical equivalence for direct substitution in applications where the 3M 10003 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 10003 and Panduit SCS2-Q are active-status products with equivalent regulatory compliance. The 3M 10003 carries RoHS Compliant certification, while the Panduit SCS2-Q carries ROHS3 Compliant certification. Both parts maintain REACH Unaffected status and identical ECCN and HTSUS classifications, confirming regulatory equivalence for procurement and deployment.

Selection between these parts should be based on availability, lead time, and procurement channel preferences, as both satisfy identical electrical and mechanical requirements for 2 AWG butt splice crimp termination applications.

Frequently Asked Questions (FAQ)

Q: Can the Panduit SCS2-Q replace the 3M 10003 in existing designs?

A: Yes. Both parts are functionally equivalent across all critical parameters: terminal type, wire gauge, termination method, insulation, and wire material. Direct substitution is supported without design modification.

Q: Are there any differences in RoHS compliance between these parts?

A: The 3M 10003 is RoHS Compliant, while the Panduit SCS2-Q is ROHS3 Compliant. Both certifications satisfy RoHS requirements; ROHS3 represents a more recent compliance standard. Both parts are acceptable for applications requiring RoHS compliance.

Q: What wire gauge range does the 2 AWG specification cover?

A: Both parts are rated specifically for 2 AWG wire. This specification is fixed and non-negotiable for substitution eligibility.

Q: Are these parts suitable for insulated or non-insulated applications?

A: Both parts are non-insulated terminals. They are designed for use with bare copper wire and do not provide insulation covering. Applications requiring insulated terminals require different part selection.

Q: What is the significance of the "Individual Openings" terminal type?

A: Individual Openings indicates that each wire entry has a separate, distinct opening for crimp termination. This design ensures proper wire seating and connection integrity for butt splice applications.
