CT-35 Equivalent & Substitute Parts Reference

Part Overview

The CT-35 is a 35-circuit barrier block connector manufactured by Curtis Industries, designed for chassis and panel mounting applications. This terminal block features dual-wall barrier construction with screw termination on top and closed termination on the bottom, rated for 30A at 600V with wire gauge compatibility of 10-22 AWG.

The CT-35 carries an obsolete product status. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and replacement applications where this connector type is specified in existing designs or systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-35 is determined by strict equivalence across the following critical parameters:

• Number of circuits: 35
• Pitch spacing: 0.546" (13.86mm)
• Current rating: 30A
• Voltage rating: 600V
• Wire gauge compatibility: 10-22 AWG
• Barrier type: 2 Wall (Dual)
• Top termination method: Screws
• Bottom termination: Closed
• Mounting configuration: Chassis, Panel
• Operating temperature: 130°C
• Insulation material: Polyester Thermoplastic
• Flammability rating: UL94 V-0

The CDM-35 meets all substitution criteria as a direct equivalent barrier block connector with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CDM-35 is the direct equivalent substitute for the obsolete CT-35. Both parts are manufactured by Curtis Industries and share identical electrical and mechanical specifications across all critical parameters.

The CDM-35 carries active product status, ensuring ongoing availability and supply chain continuity. The CDM-35 maintains full compliance with RoHS3 standards and all environmental certifications equivalent to the CT-35. Both parts meet UL94 V-0 flammability requirements and carry unlimited moisture sensitivity classification.

Selection of the CDM-35 as a replacement for CT-35 applications requires no design modifications, as all functional and physical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the CDM-35 be used as a direct replacement for the CT-35?

A: Yes. The CDM-35 is a direct equivalent substitute. All electrical ratings (30A, 600V), mechanical dimensions (35 circuits at 0.546" pitch), termination methods (screw top, closed bottom), and material specifications are identical between the two parts.

Q: What is the primary difference between CT-35 and CDM-35?

A: The CT-35 is obsolete, while the CDM-35 is an active product. The CDM-35 carries ROHS3 compliance compared to the CT-35's RoHS compliance. All functional specifications remain equivalent.

Q: Are there any packaging differences between these parts?

A: The CT-35 packaging specification is not provided. The CDM-35 is supplied in bulk packaging. Confirm packaging requirements for your application.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the CT-35 and CDM-35 accept wire gauges from 10-22 AWG with identical screw termination on the top side.

Q: Are mounting configurations identical?

A: Yes. Both parts support chassis and panel mounting configurations with identical flange and marking strip features.

Q: What is the operating temperature range for these connectors?

A: Both the CT-35 and CDM-35 are rated for operation up to 130°C maximum.
