CT-50 Equivalent & Substitute Parts

Part Overview

The CT-50 is a 50-circuit barrier block connector manufactured by Curtis Industries, designed for chassis and panel mounting applications requiring high-density terminal connections. This component features dual-wall barrier construction with screw termination on the top and closed termination on the bottom, rated for 30A at 600V with wire gauge compatibility from 10-22 AWG.

The CT-50 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications currently utilizing this connector in production or maintenance scenarios.

Key Parameters

Substitute Part Grouping Explanation

The CDM-50 qualifies as a direct substitute for the CT-50 based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Number of circuits: 50
• Pitch spacing: 0.546" (13.86mm)
• Number of rows: 2
• Current rating: 30A
• Voltage rating: 600V
• Wire gauge range: 10-22 AWG
• Top termination method: Screws
• Barrier type: 2 Wall (Dual)
• Operating temperature: 130°C
• Insulation material: Polyester Thermoplastic
• Flammability rating: UL94 V-0

The CDM-50 maintains identical electrical performance and mechanical compatibility with the obsolete CT-50, enabling direct substitution in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The CDM-50 is the appropriate substitute for the obsolete CT-50. Both components are manufactured by Curtis Industries and maintain identical electrical and mechanical specifications across all critical parameters.

The CDM-50 carries active product status, ensuring ongoing availability and supply chain continuity. The CDM-50 meets ROHS3 compliance, representing current regulatory standards, while the CT-50 meets RoHS compliance. Both components satisfy UL94 V-0 flammability requirements and maintain unlimited moisture sensitivity level (MSL 1) classification.

For applications currently specified with CT-50 connectors, direct substitution with CDM-50 units requires no design modifications or re-qualification, as all functional and mechanical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the CDM-50 be used as a direct replacement for the CT-50?

A: Yes. The CDM-50 provides direct substitution for the CT-50. All electrical ratings (30A, 600V), mechanical dimensions (50 circuits, 0.546" pitch, 2 rows), termination methods (screw top, closed bottom), and material specifications (Polyester Thermoplastic, UL94 V-0) are identical between the two parts.

Q: What is the primary difference between the CT-50 and CDM-50?

A: The CT-50 is obsolete, while the CDM-50 maintains active product status. The CDM-50 also carries ROHS3 compliance compared to the CT-50's RoHS compliance. These differences do not affect electrical or mechanical compatibility.

Q: Are there packaging differences between CT-50 and CDM-50?

A: The CT-50 is packaged in standard format, while the CDM-50 is supplied in bulk packaging. This distinction affects procurement and handling but does not impact component performance or compatibility.

Q: What wire gauges are compatible with the CDM-50?

A: The CDM-50 accepts wire gauges from 10-22 AWG, matching the CT-50 specification. This range accommodates both larger and smaller conductor sizes within a single connector footprint.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the CT-50 and CDM-50 are rated for continuous operation at 130°C, making them suitable for elevated-temperature industrial environments.
