Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching the following parameters: terminal block type, number of circuits, pitch, current rating, voltage rating, wire gauge, termination types, barrier type, mounting type, operating temperature, insulation material, flammability rating, RoHS status, REACH status, and mechanical features. Only parts meeting all explicit criteria are considered as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The Curtis Industries CT-7 is obsolete, whereas the Curtis Industries CDM-7 is active and meets all specified key parameters, including electrical and mechanical characteristics as well as RoHS and REACH compliance. CDM-7 provides equivalent function and compliance for direct substitution.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for accepting a substitute terminal block for CT-7?
A1: Allowed substitutes must match the number of circuits, pitch, current and voltage ratings, wire gauge range, barrier type, mounting method, operating temperature, insulation material, flammability rating, and regulatory compliance exactly as specified.

Q2: Is the substitute part CDM-7 compatible with the same installation footprint and wiring as CT-7?
A2: CDM-7 matches all input parameters provided for circuit count, pitch, termination, and mounting, supporting installation in the same application context.

Q3: Are there packaging or moisture sensitivity considerations for switching from CT-7 to CDM-7?
A3: Both parts are supplied in bulk packaging and have the same moisture sensitivity level (MSL 1, unlimited).

Q4: Is there any difference in regulatory or RoHS compliance between CT-7 and CDM-7?
A4: Both parts are RoHS and REACH compliant as per the provided data, with CDM-7 specified as ROHS3 Compliant.

Q5: What is the significance of the product status in selecting substitutes?
A5: CT-7 is obsolete, making continued service or production challenging. CDM-7, being active and align with all key parameters, is suitable for direct replacement in compliance-sensitive applications.
