Parameter Comparison

Engineering Selection Recommendations

CT-47 is obsolete. CDM-47 is an active part, matching all primary electrical and mechanical characteristics and compliance certifications: RoHS, REACH unaffected, and UL94 V-0 flammability rating. Moisture sensitivity and regulatory codes (ECCN, HTSUS) are equivalent. Use CDM-47 for continued availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: What criteria determine if CDM-47 can substitute for CT-47?
A: Substitute selection is based exclusively on: terminal block type, number of circuits, wire entries, pitch, rows, electrical ratings, termination methods, mounting type, material, regulatory compliance, and certifications.

Q: Are there any differences in performance or compatibility when switching to CDM-47?
A: All key functional, mechanical, and compliance parameters are identical as provided, ensuring compatibility in approved applications for CT-47.

Q: Does the packaging or part status affect interchangeability?
A: Both CT-47 and CDM-47 are supplied in bulk packaging. CDM-47 holds an active product status while CT-47 is obsolete.

Q: What should be considered regarding compliance and certifications when substituting?
A: Both the main and substitute parts are RoHS compliant, REACH unaffected, and meet the same UL94 flammability rating. Moisture Sensitivity Level is 1 (Unlimited) for both.

Q: Can the substitute be used without physical modification to the application?
A: Both parts share all listed mechanical and electrical parameters, including mounting type, pitch, and dimensions, ensuring drop-in replacement per the provided data.
