Equivalent & Substitute Parts for CT-13 Terminal Block

Part Overview

CT-13 (Curtis Industries) is a barrier block terminal block, featuring 13 circuits and a 0.546" (13.86mm) pitch, designed for chassis or panel mounting. The CT-13 barrier block utilizes screw terminations, supports wire gauges from 10-22 AWG, and is rated for 30A and 600V. It is constructed with polyester thermoplastic insulation and meets UL94 V-0 flammability requirements. The CT-13 model is currently obsolete, making identification of equivalent substitute models necessary to maintain compatibility in existing designs and ensure continued production or service support.

Substitute Part Grouping Explanation

Substitute assignment for terminal blocks in this reference is based strictly on matching key electrical, mechanical, and compliance parameters. Fields required for substitution include: terminal block type, number of circuits, pitch, number of wire entries, number of rows, current rating, voltage rating, wire gauge, termination style, barrier type, features, mounting type, operating temperature, insulation material, flammability rating, and compliance certifications (RoHS and REACH). Only direct substitutions matching all these listed parameters are included.

Engineering Selection Recommendations

The CT-13 terminal block is obsolete. The CDM-13 terminal block from Curtis Industries is active, matches all listed electrical, mechanical, and compliance parameters, and is suitable as a direct substitute. Both parts are RoHS and REACH compliant and have an identical Moisture Sensitivity Level (1, Unlimited). The insulation material, flammability rating, and mounting options are consistent. Both products support the same number of circuits and wire gauges, making CDM-13 a direct replacement for CT-13 under the defined criteria.

Frequently Asked Questions (FAQ)

Q1: What are the required parameters for substituting CT-13 with another terminal block?
A1: Substitution requires identical parameters in terminal block type, number of circuits, pitch, wire entries, rows, current rating, voltage rating, wire gauge, termination style, barrier type, features, mounting type, operating temperature, insulation material, flammability rating, and compliance certifications.

Q2: Is CDM-13 dimensionally equivalent to CT-13 for panel or chassis mounting?
A2: The CDM-13 has the same pitch, number of circuits, rows, and mounting type as CT-13 and is considered dimensionally equivalent based on the provided parameters.

Q3: Does the substitute part maintain RoHS and REACH compliance?
A3: Yes, both CT-13 and CDM-13 are specified as RoHS and REACH compliant.

Q4: Can wire gauges and termination hardware used for CT-13 be directly transferred to CDM-13?
A4: Both models support 10-22 AWG wire and use screw terminations, providing compatibility.

Q5: Are there any differences in flame retardance or operating temperature between CT-13 and CDM-13?
A5: Both parts are specified with polyester thermoplastic insulation, UL94 V-0 flammability rating, and a 130°C operating temperature.

Q6: Does the substitute part offer the same barrier configuration and features?
A6: Both CT-13 and CDM-13 feature a 2 Wall (Dual) barrier type, flange, and marking strip, matching the specified configuration.

Q7: Is the packaging type relevant to the substitution?
A7: Both parts are identified as supplied in bulk packaging. No additional packaging details are given in the substitution criteria.
