CT-15 Equivalent & Substitute Parts

Part Overview

The CT-15 is a 15-circuit barrier block connector manufactured by Curtis Industries, designed for chassis and panel mounting applications requiring secure wire termination. This component features dual-wall barrier construction with screw termination, rated for 30A at 600V across wire gauges 10-22 AWG. The CT-15 is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations. The CDM-15 serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering current production availability.

Substitute Part Grouping Explanation

The CDM-15 qualifies as a direct substitute for the CT-15 based on strict equivalence across all critical electrical and mechanical parameters. Substitution is valid when the following conditions are met:

• Identical circuit count: 15 circuits
• Matching pitch specification: 0.546" (13.86mm)
• Equivalent current and voltage ratings: 30A at 600V
• Same wire gauge compatibility: 10-22 AWG
• Identical termination method: Screw top termination with closed bottom
• Matching barrier construction: 2 Wall (Dual) configuration
• Compatible mounting interfaces: Chassis and panel mounting
• Equivalent thermal and material specifications: 130°C operating temperature, Polyester Thermoplastic insulation, UL94 V-0 rating

The CDM-15 maintains full compatibility with existing CT-15 installations and new designs requiring this connector specification.

Parameter Comparison

Engineering Selection Recommendations

The CDM-15 is the appropriate selection for applications currently using or specifying the CT-15. The CDM-15 maintains active production status with Curtis Industries, ensuring long-term availability and supply chain continuity. Both parts carry equivalent regulatory compliance: RoHS certification (CT-15 RoHS Compliant, CDM-15 ROHS3 Compliant) and REACH unaffected status. The CDM-15 is available in bulk packaging with 773 units in current inventory, supporting both replacement and new design requirements. No functional or electrical compromises result from this substitution.

Frequently Asked Questions (FAQ)

Q: Can the CDM-15 directly replace the CT-15 in existing installations?

A: Yes. The CDM-15 provides direct replacement capability. All electrical ratings (30A, 600V), mechanical dimensions (0.546" pitch, 15 circuits, 2 rows), termination methods (screw top, closed bottom), and material specifications (Polyester Thermoplastic, UL94 V-0) are identical. Mounting interfaces for chassis and panel applications are equivalent.

Q: What is the primary reason to transition from CT-15 to CDM-15?

A: The CT-15 is classified as obsolete. The CDM-15 is an active production part from the same manufacturer, ensuring continued availability, technical support, and supply chain reliability.

Q: Are there packaging differences between CT-15 and CDM-15?

A: The CT-15 packaging specification is not provided in the available data. The CDM-15 is supplied in bulk packaging. Confirm packaging requirements for your specific application needs.

Q: Do both parts meet current regulatory standards?

A: Yes. The CT-15 carries RoHS Compliant certification. The CDM-15 carries ROHS3 Compliant certification, representing the current regulatory standard. Both parts maintain REACH unaffected status.

Q: What wire gauges are supported by the CDM-15?

A: The CDM-15 accepts wire gauges 10-22 AWG, identical to the CT-15 specification.

Q: Are there any electrical performance differences?

A: No. Both parts are rated for 30A at 600V with identical dual-wall barrier construction and screw termination. Operating temperature rating is 130°C for both.
