CT-49 Equivalent & Substitute Parts

Part Overview

The CT-49 is a 49-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-49 is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-49 is determined by strict equivalence across the following critical parameters:

• Number of circuits: 49
• Pitch spacing: 0.546" (13.86mm)
• Current rating: 30A
• Voltage rating: 600V
• Wire gauge compatibility: 10-22 AWG
• Termination type: Screw top, closed bottom
• Barrier configuration: 2 Wall (Dual)
• Operating temperature: 130°C
• Insulation material: Polyester Thermoplastic
• Flammability rating: UL94 V-0

The CDM-49 meets all substitution criteria as a direct functional equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CDM-49 is the direct substitute for the obsolete CT-49. Both components are manufactured by Curtis Industries and maintain identical electrical and mechanical specifications across all critical parameters. The CDM-49 carries active product status and meets current ROHS3 compliance requirements, making it the appropriate selection for new procurement and system maintenance applications. The transition from CT-49 to CDM-49 requires no design modifications or system reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can the CDM-49 be used as a direct replacement for the CT-49 in existing installations?

A: Yes. The CDM-49 is electrically and mechanically equivalent to the CT-49. All circuit counts, pitch spacing, current and voltage ratings, wire gauge compatibility, termination methods, and mounting configurations are identical.

Q: What is the primary reason for substituting the CT-49?

A: The CT-49 is classified as obsolete. The CDM-49 is the active equivalent from the same manufacturer with identical specifications.

Q: Are there any compliance differences between the CT-49 and CDM-49?

A: Both components meet UL94 V-0 flammability requirements and REACH compliance. The CDM-49 carries ROHS3 certification, while the CT-49 carries RoHS compliance. Both statuses satisfy current regulatory requirements.

Q: Does packaging differ between these components?

A: The CT-49 packaging specification is not provided. The CDM-49 is supplied in bulk packaging.

Q: Are there any installation or wiring differences?

A: No. Both components use identical screw termination on the top, closed termination on the bottom, and support the same wire gauge range of 10-22 AWG.
