Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly based on the following key parameters: terminal block type, number of circuits, number of wire entries, pitch, number of rows, current rating, voltage rating, wire gauge, top termination, bottom termination, barrier type, features, mounting type, operating temperature, insulation material, flammability rating, RoHS status, moisture sensitivity level (MSL), REACH status, ECCN, and HTSUS. Only parts matching all these parameters are considered equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of Curtis Industries CDM-42 as a substitute for CT-42 is based on exact alignment across all key parameters, including electrical ratings, mechanical configuration, environmental ratings, and regulatory compliance. The CT-42 is obsolete, while the CDM-42 is active and RoHS3 compliant, maintaining the required certifications and compliance for replacement.

Frequently Asked Questions (FAQ)

Q1: What factors are required for selecting a substitute for Curtis Industries CT-42?
A1: The substitute must match the original part in terminal block type, number of circuits, number of wire entries, pitch, electrical ratings, wire gauge, termination configuration, barrier construction, mounting, operating temperature, insulation material, flammability rating, and regulatory compliance.

Q2: Is CDM-42 fully compatible with CT-42 for electrical and mechanical applications?
A2: Yes, CDM-42 is compatible with CT-42 based on all defined key parameters, ensuring identical functionality within the terminal blocks category.

Q3: What is the impact of product status (Obsolete vs. Active) on engineering selection?
A3: The obsolete status of CT-42 necessitates using an active equivalent such as CDM-42 to ensure continued availability and compliance in production or maintenance.

Q4: Are there package or inventory differences to be considered?
A4: Both models are available in bulk packaging. Inventory quantities should be verified as provided. Only the provided packaging information is considered.
