TCTS-250-1/2-U Equivalent & Substitute Parts

Part Overview

The TCTS-250-1/2-U is a compression connector terminal manufactured by TE Energy & Utilities, designed for 250MCM (kcmil) wire gauge applications with a 1/2 stud configuration. This rectangular standard terminal connector features crimp barrel termination and is rated for free-hanging in-line mounting. The product is currently obsolete, making identification of functionally equivalent alternatives essential for maintenance, repair, and replacement applications where this connector type is specified in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TCTS-250-1/2-U is determined by strict equivalence across the following critical parameters:

• Wire gauge: 250MCM (kcmil) — exact match required
• Stud/tab size: 1/2 stud — exact match required
• Terminal style: Single stud hole — exact match required
• Termination method: Crimp, barrel — exact match required
• Contact material: Copper — exact match required
• Insulation type: Non-insulated — exact match required
• Mounting configuration: Free hanging (in-line) — exact match required

The 3M 31049 terminal connector meets all critical substitution criteria. Both connectors are rated for identical wire gauges, stud configurations, and termination methods. Dimensional variations in overall length and barrel outer diameter do not affect functional compatibility within the specified electrical and mechanical parameters for this product category.

Parameter Comparison

Engineering Selection Recommendations

The 3M 31049 terminal connector is a direct functional equivalent for the obsolete TCTS-250-1/2-U. Both components satisfy identical electrical and mechanical requirements for 250MCM wire gauge applications with 1/2 stud termination. The 31049 is currently in active production status, ensuring availability for replacement and new installations.

Both connectors maintain RoHS compliance and are suitable for applications requiring non-insulated copper compression terminals with crimp barrel termination. The 31049 is part of the Scotchlok™ 31000 series, a recognized standard in rectangular terminal connector applications.

Minor dimensional differences between the two connectors (overall length and barrel outer diameter) do not affect functional compatibility within the specified electrical and mechanical parameters for this product category. The barrel inner diameter variance (0.590" versus 0.595") remains within acceptable tolerance for 250MCM wire gauge applications.

Frequently Asked Questions (FAQ)

Q: Can the 3M 31049 be used as a direct replacement for the TCTS-250-1/2-U?

A: Yes. Both connectors are rated for 250MCM wire gauge with 1/2 stud configuration, single stud hole terminal style, and crimp barrel termination. All critical electrical and mechanical parameters are equivalent.

Q: What is the significance of the different overall lengths between these connectors?

A: The TCTS-250-1/2-U measures 2.670" overall length while the 31049 measures 3.382". This dimensional difference does not affect electrical performance or functional compatibility in free-hanging in-line mounting applications. Physical space constraints in specific installations should be evaluated during component selection.

Q: Are there differences in contact finish between these two connectors?

A: The TCTS-250-1/2-U features tin contact finish, while the 31049 uses electro-tin contact finish. Both finishes provide equivalent corrosion resistance and electrical conductivity for this application category.

Q: Why is the TCTS-250-1/2-U listed as obsolete?

A: The TCTS-250-1/2-U is no longer in active production. The 3M 31049 serves as the current production equivalent for applications requiring 250MCM rectangular terminal connectors with 1/2 stud configuration.

Q: Are both connectors RoHS compliant?

A: Yes. Both the TCTS-250-1/2-U and 31049 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What packaging is available for these connectors?

A: Both connectors are supplied in bulk packaging, suitable for industrial and OEM applications requiring high-volume component procurement.
