Engineering Selection Recommendations

The CDM-34 is the qualified substitute for the CT-34 based on complete electrical and mechanical parameter equivalence. The CDM-34 carries active product status, ensuring ongoing availability and supply chain continuity. Both components maintain identical compliance certifications including UL94 V-0 flammability rating and REACH unaffected status. The CDM-34 meets ROHS3 compliance, representing current regulatory alignment. Selection of the CDM-34 eliminates obsolescence risk while maintaining full functional and dimensional compatibility with existing CT-34 installations.

Frequently Asked Questions (FAQ)

Q: Can the CDM-34 be used as a direct replacement for the CT-34 in existing applications?

A: Yes. The CDM-34 provides complete electrical and mechanical equivalence to the CT-34. All critical parameters including circuit count, pitch spacing, current and voltage ratings, wire gauge compatibility, termination methods, and operating temperature specifications are identical. Physical mounting compatibility is maintained for both chassis and panel mounting configurations.

Q: What is the primary advantage of switching from CT-34 to CDM-34?

A: The CDM-34 carries active product status, whereas the CT-34 is obsolete. This ensures reliable supply availability, eliminates long-lead-time risks, and provides access to current manufacturing and quality standards.

Q: Are there any compliance differences between the CT-34 and CDM-34?

A: Both components maintain UL94 V-0 flammability certification and REACH unaffected status. The CDM-34 meets ROHS3 compliance, representing current regulatory requirements. No compliance barriers exist for substitution.

Q: Does packaging differ between these parts?

A: The CT-34 packaging specification is not provided in the reference data. The CDM-34 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are the wire entry configurations identical?

A: Yes. Both the CT-34 and CDM-34 feature 68 wire entries across 34 circuits in a 2-row configuration with 0.546" pitch spacing.
