Curtis Industries CT-1 Equivalent & Substitute Terminal Block Reference

Part Overview

The Curtis Industries CT-1 is a barrier block terminal connector designed for single-circuit applications, featuring screw-type wire termination and dual wall barriers. As an obsolete product, sourcing the CT-1 for new designs or maintenance is not feasible. In such cases, direct substitutes with identical electrical, mechanical, and compliance specifications are required to ensure reliable compatibility without deviating from the original design criteria.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the CT-1 terminal block are qualified based strictly on identical core parameters. Substitution logic is limited to matching the following fields: manufacturer, category, terminal block type, circuit count, wire entries, rows, electrical ratings, termination style, barrier type, mounting type, operating temperature, insulation material, flammability rating, compliance status (RoHS, REACH), ECCN, and HTSUS code. Only those parts with matching values for all these parameters are considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The CT-1 is obsolete and no longer available for new builds or service replacement. The CDM-1 from Curtis Industries is an active part that fulfills all identical electrical, mechanical, and regulatory criteria provided for the CT-1, including RoHS and REACH compliance, operating temperature, current, voltage ratings, material specifications, mounting options, and certification codes. No deviation occurs between these listed fields for the substitution.

Frequently Asked Questions (FAQ)

Q1: What determines direct substitution compatibility for Curtis Industries barrier block terminal blocks?
Compatibility is determined by identical matching of circuit count, wire entry count, row count, current and voltage ratings, wire gauge range, termination and barrier styles, mounting type, insulation material, flammability rating, operating temperature, and compliance status.

Q2: Is the CDM-1 a form-fit-function substitute for the CT-1?
All provided parameters for CDM-1 match the CT-1, qualifying CDM-1 as a direct substitute in applications where the CT-1 was used.

Q3: Are there any differences in compliance or certification between CT-1 and CDM-1?
Both parts are RoHS and REACH compliant, with matching ECCN and HTSUS codes. RoHS status is listed as ‘RoHS Compliant’ for CT-1 and ‘ROHS3 Compliant’ for CDM-1, both indicating unrestricted use in regulated environments.

Q4: Are packaging options relevant to terminal block substitutability?
Both CT-1 and CDM-1 are provided in bulk packaging, ensuring identical handling and installation processes.

Q5: Does terminal screw material or finish affect substitution for CT-1 and CDM-1?
No explicit data on terminal screw material or finish is provided; all other technical specifications are matched for direct substitution.
