CT-17 Equivalent & Substitute Parts

Part Overview

The CT-17 is a 17-circuit barrier block connector manufactured by Curtis Industries, designed for chassis and panel mounting applications. This component features dual-wall barrier construction with screw termination on the top and closed termination on the bottom. The CT-17 operates at 600V with a 30A current rating and accommodates wire gauges from 10-22 AWG.

The CT-17 is classified as obsolete. Identification of equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CT-17 terminal block is determined by electrical and mechanical parameter equivalence. The following parameters establish substitution compatibility:

• Circuit Configuration: 17 circuits with 34 wire entries across 2 rows
• Pitch Specification: 0.546" (13.86mm) center-to-center spacing
• Electrical Ratings: 30A current capacity and 600V voltage rating
• Termination Method: Screw-based top termination with closed bottom termination
• Barrier Construction: Dual-wall (2 Wall) barrier type
• Wire Accommodation: 10-22 AWG wire gauge range
• Mounting Configuration: Chassis and panel mounting capability
• Material and Thermal Properties: Polyester thermoplastic insulation rated to 130°C with UL94 V-0 flammability classification

The CDM-17 meets all specified parameters and qualifies as a direct substitute for the CT-17.

Parameter Comparison

Engineering Selection Recommendations

The CDM-17 is the qualified substitute for the CT-17 barrier block connector. Both components are manufactured by Curtis Industries and maintain identical electrical, mechanical, and thermal specifications across all critical parameters.

The CDM-17 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The CDM-17 maintains RoHS3 compliance, representing current regulatory alignment compared to the CT-17's RoHS compliance designation. Both components satisfy REACH and export control requirements under identical classifications.

All electrical ratings, termination methods, wire accommodation ranges, mounting configurations, and material specifications are equivalent between the two parts. The dual-wall barrier construction, flange features, and marking strip provisions are preserved in the substitute.

Selection of the CDM-17 for new applications or replacement scenarios provides functional equivalence with improved product lifecycle status.
