Engineering Selection Recommendations

The CDM-41 is the appropriate substitute for the CT-41 due to product status alignment. The CT-41 is classified as obsolete, while the CDM-41 maintains active production status. Both components meet identical electrical specifications, mechanical dimensions, and regulatory compliance requirements. The CDM-41 carries ROHS3 compliance, representing current regulatory standards, whereas the CT-41 carries RoHS compliance. Both maintain REACH Unaffected status. Selection of the CDM-41 ensures access to actively manufactured inventory and ongoing supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the CDM-41 directly replace the CT-41 in existing installations?

A: Yes. The CDM-41 provides direct functional replacement. All electrical parameters, mechanical dimensions, termination methods, and mounting configurations are identical between the two components.

Q: What is the primary reason for substitution?

A: The CT-41 is classified as obsolete. The CDM-41 is the active equivalent, ensuring continued availability and supply chain support.

Q: Are there differences in regulatory compliance between these parts?

A: Both components meet UL94 V-0 flammability requirements and REACH Unaffected status. The CDM-41 carries ROHS3 compliance, representing current regulatory standards, while the CT-41 carries RoHS compliance.

Q: Do the CT-41 and CDM-41 have identical wire gauge ratings?

A: Yes. Both components accept wire gauges from 10-22 AWG with identical current and voltage ratings of 30A and 600V respectively.

Q: Are there packaging differences between the CT-41 and CDM-41?

A: The CT-41 packaging specification is not provided. The CDM-41 is supplied in bulk packaging. Verify packaging requirements for your application.

Q: What is the pitch spacing for both components?

A: Both the CT-41 and CDM-41 feature 0.546" (13.86mm) pitch spacing with 41 circuits arranged in 2 rows.
