CT-5 Equivalent & Substitute Parts Reference

Part Overview

The CT-5 is a 5-circuit barrier block connector manufactured by Curtis Industries, designed for applications requiring secure screw-terminated electrical connections. This component features dual-wall barrier construction with a 0.546" (13.86mm) pitch and supports up to 30A at 600V. The CT-5 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

The CDM-5 qualifies as a direct substitute for the CT-5 based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Number of circuits: 5
• Pitch spacing: 0.546" (13.86mm)
• Current rating: 30A minimum
• Voltage rating: 600V minimum
• Wire gauge compatibility: 10-22 AWG
• Top termination method: Screws
• Barrier type: 2 Wall (Dual)
• Operating temperature: 130°C minimum
• Insulation material: Polyester Thermoplastic
• Flammability rating: UL94 V-0

The CDM-5 meets all these parameters and is classified as an active product, providing improved availability compared to the obsolete CT-5.

Parameter Comparison

Engineering Selection Recommendations

The CDM-5 is the appropriate substitute for the CT-5 in all applications where the CT-5 was previously specified. Both components are manufactured by Curtis Industries and share identical electrical and mechanical specifications across all critical parameters.

The CDM-5 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The CDM-5 maintains full compliance with RoHS3 and REACH requirements, meeting current regulatory standards. Both components carry UL94 V-0 flammability certification and are rated for identical operating conditions.

Mechanical compatibility is confirmed through matching pitch spacing (0.546"), circuit count (5), wire entry configuration (10), and mounting provisions (Chassis, Panel). Electrical performance is equivalent across current rating (30A), voltage rating (600V), and wire gauge acceptance (10-22 AWG).

Frequently Asked Questions (FAQ)

Q: Can the CDM-5 be used as a direct replacement for the CT-5 in existing installations?

A: Yes. The CDM-5 meets all electrical and mechanical specifications of the CT-5. Physical dimensions, pitch spacing, circuit configuration, and termination method are identical. The component can be substituted without modification to mounting hardware or wiring practices.

Q: What is the primary reason for substituting the CT-5 with the CDM-5?

A: The CT-5 is classified as obsolete, limiting availability. The CDM-5 is an active product from the same manufacturer with identical specifications, providing reliable sourcing for replacement and new applications.

Q: Are there any compliance differences between the CT-5 and CDM-5?

A: Both components meet REACH and EAR99 export control requirements. The CDM-5 carries ROHS3 certification while the CT-5 carries RoHS Compliant status. Both maintain UL94 V-0 flammability rating and identical moisture sensitivity levels.

Q: What packaging options are available for the CDM-5?

A: The CDM-5 is available in bulk packaging. The CT-5 original packaging specification is not provided in the available data.

Q: Are the screw termination specifications identical between both parts?

A: Yes. Both the CT-5 and CDM-5 use screw-type top termination with closed bottom termination. Wire gauge acceptance (10-22 AWG) and current handling (30A) are identical.

Q: Can the CDM-5 be used in applications rated for 600V operation?

A: Yes. The CDM-5 is rated for 600V operation, matching the CT-5 specification. Operating temperature range is also identical at 130°C maximum.
