CT-32 Equivalent & Substitute Parts

Part Overview

The CT-32 is a 32-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-32 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.

Substitute Part Grouping Explanation

Substitution of the CT-32 is determined by strict equivalence across the following critical parameters:

  • Terminal block type (Barrier Block)
  • Number of circuits (32)
  • 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 construction (2 Wall / Dual)
  • Operating temperature (130°C)
  • Insulation material (Polyester Thermoplastic)
  • Flammability rating (UL94 V-0)
  • Mounting type (Chassis, Panel)

The CDM-32 meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: CT-32 is obsolete while CDM-32 is active, making CDM-32 the recommended selection for new procurement and ongoing applications.

Engineering Selection Recommendations

The CDM-32 is the direct substitute for the CT-32 barrier block connector. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The CDM-32 carries active product status, ensuring ongoing availability and support, whereas the CT-32 is obsolete.

The CDM-32 meets current RoHS3 compliance requirements compared to the CT-32's RoHS compliance designation. Both parts satisfy REACH requirements and carry identical environmental and safety certifications including UL94 V-0 flammability rating.

For applications currently using CT-32 connectors, the CDM-32 provides full functional and physical compatibility without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can CDM-32 replace CT-32 in existing designs? A: Yes. The CDM-32 is electrically and mechanically equivalent to the CT-32 across all specified parameters including circuit count, pitch, current rating, voltage rating, wire gauge compatibility, and termination method. Direct substitution is supported.

Q: What is the primary difference between CT-32 and CDM-32? A: The CT-32 is obsolete while the CDM-32 is an active product. Both parts are manufactured by Curtis Industries and share identical electrical and mechanical specifications. The CDM-32 also carries ROHS3 compliance versus RoHS compliance for the CT-32.

Q: Are there packaging differences between these parts? A: The CT-32 packaging specification is not provided. The CDM-32 is supplied in bulk packaging. Confirm packaging requirements for your application.

Q: Do these parts require any design changes for substitution? A: No design changes are required. The CDM-32 maintains the same mounting type (chassis, panel), flange configuration, marking strip features, and all electrical ratings as the CT-32.

Q: What wire gauges are compatible with these connectors? A: Both the CT-32 and CDM-32 accept wire gauges from 10-22 AWG with screw termination on the top entry.
