Key Parameters

Substitute Part Grouping Explanation

The CDM-2 qualifies as a direct substitute for the CT-2 based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

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

The CDM-2 meets all specified parameters, making it functionally equivalent for direct replacement in applications currently using the CT-2.

Parameter Comparison

Engineering Selection Recommendations

The CDM-2 is the appropriate substitute for the obsolete CT-2. All electrical specifications, mechanical dimensions, and termination methods are identical. The CDM-2 maintains active product status with Curtis Industries, ensuring continued availability and supply chain reliability. The CDM-2 carries ROHS3 compliance, representing an updated regulatory standard compared to the CT-2's RoHS compliance. Both components share identical REACH and ECCN classifications, confirming regulatory equivalence for international applications.

Frequently Asked Questions (FAQ)

Q: Can the CDM-2 be used as a direct replacement for the CT-2 in existing installations?

A: Yes. The CDM-2 matches all electrical and mechanical parameters of the CT-2, including current rating (30A), voltage rating (600V), wire gauge compatibility (10-22 AWG), pitch (0.546"), and termination method (screws). Physical mounting and electrical performance are identical.

Q: What is the primary difference between the CT-2 and CDM-2?

A: The CT-2 is classified as obsolete, while the CDM-2 is an active product. The CDM-2 carries updated ROHS3 compliance versus the CT-2's RoHS compliance. All functional specifications remain equivalent.

Q: Are there packaging differences between these parts?

A: The CT-2 packaging specification is not provided. The CDM-2 is supplied in bulk packaging. Confirm packaging requirements for your application before procurement.

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

A: Yes. Both the CT-2 and CDM-2 accept wire gauges 10-22 AWG with identical screw termination.

Q: Are there any compliance or certification differences?

A: Both parts carry UL94 V-0 flammability rating, MSL 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification. The CDM-2 carries ROHS3 compliance, which supersedes the CT-2's RoHS compliance.

Q: What is the barrier configuration for these components?

A: Both the CT-2 and CDM-2 feature 2 Wall (Dual) barrier construction, providing electrical isolation between circuits.
