Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TCSL-1000-U is determined by strict alignment of the following critical parameters:

• Terminal Type: Butt Splice, Inline, Individual Openings
• Wire Gauge: 1000MCM (kcmil)
• Number of Wire Entries: 2
• Termination Method: Crimp
• Insulation Type: Non-Insulated

The substitute part SCL1000-3 meets all these criteria, establishing functional equivalence for direct replacement in applications requiring 1000MCM butt splice crimp connectors with individual opening configurations.

Engineering Selection Recommendations

The SCL1000-3 (Panduit Corp) is the qualified substitute for the obsolete TCSL-1000-U. Selection is based on:

• Functional Equivalence: Identical terminal type, wire gauge, wire entry configuration, and termination method
• Product Status: SCL1000-3 maintains active production status, ensuring supply chain availability and long-term support
• Regulatory Compliance: Both parts meet export control requirements (EAR99) and harmonized tariff classifications (HTSUS 8536.90.4000). SCL1000-3 carries ROHS3 Compliant certification, exceeding the RoHS Compliant status of the main part
• Series Designation: SCL1000-3 is part of the Pan-Lug™ series, a recognized product line for high-capacity terminal applications

Frequently Asked Questions (FAQ)

Q: Can SCL1000-3 be used as a direct replacement for TCSL-1000-U?

A: Yes. Both parts share identical specifications for terminal type, wire gauge (1000MCM), wire entry configuration (2 entries), termination method (crimp), and insulation type (non-insulated). The parts are functionally equivalent for inline butt splice applications.

Q: What is the primary reason for substitution?

A: TCSL-1000-U is classified as obsolete. SCL1000-3 is an active product with ongoing manufacturing and supply availability.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging. No special handling or packaging conversion is required for substitution.

Q: Do compliance certifications differ between the parts?

A: Both parts are EAR99 classified and share the same HTSUS code (8536.90.4000). SCL1000-3 carries ROHS3 Compliant certification, which represents current RoHS standards. TCSL-1000-U carries RoHS Compliant certification. Both meet regulatory requirements for their respective product statuses.

Q: Is color a substitution factor?

A: TCSL-1000-U is specified as white. SCL1000-3 has no color specification provided. Color does not affect electrical or mechanical function in non-insulated butt splice applications and is not a substitution barrier.
