TCSL-350-U Equivalent & Substitute Parts

Part Overview

The TCSL-350-U is a terminal butt splice connector manufactured by TE Energy & Utilities, designed for inline, individual openings crimp termination applications. This non-insulated compression connector accommodates 350MCM (kcmil) wire gauge and is supplied in red color. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and replacement applications where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TCSL-350-U is determined by strict equivalence across the following critical parameters:

• Terminal Type: Butt Splice, Inline, Individual Openings
• Wire Gauge: 350MCM (kcmil)
• Number of Wire Entries: 2
• Termination Method: Crimp
• Insulation: Non-Insulated
• Color: Red

The substitute part SCL350-X from Panduit Corp matches all these parameters, establishing functional equivalence for direct replacement in applications where the TCSL-350-U was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The SCL350-X from Panduit Corp is the direct functional equivalent for the obsolete TCSL-350-U. Both components share identical electrical and mechanical specifications across all critical parameters. The SCL350-X carries active product status, ensuring continued availability and supply chain reliability. Both parts maintain equivalent regulatory compliance, with the SCL350-X meeting ROHS3 Compliant standards and the original part meeting RoHS Compliant standards. The SCL350-X is currently in stock with 770 pieces available, providing immediate procurement capability for replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the SCL350-X replace the TCSL-350-U in existing installations?

A: Yes. The SCL350-X matches all critical parameters: terminal type, wire gauge (350MCM), number of wire entries (2), termination method (crimp), insulation type (non-insulated), and color (red). These parameters define functional equivalence for butt splice connectors.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current iteration of the standard. Both parts meet hazardous substance restrictions applicable to terminal components.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging. The TCSL-350-U has 851 pieces in stock, while the SCL350-X has 770 pieces in stock. Packaging format is consistent across both options.

Q: Why is the TCSL-350-U classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SCL350-X, with active product status, provides continuity for applications requiring 350MCM butt splice connectors with crimp termination.

Q: Are the electrical and mechanical specifications identical?

A: Yes. Both parts are specified for 350MCM (kcmil) wire gauge with two wire entries, non-insulated construction, and crimp termination. These specifications are identical across both components.
