Engineering Selection Recommendations

The CDEP105NP-5R0MC-50 is a direct electrical and mechanical equivalent to the obsolete CDEP105-5R0MC-50. All critical electrical parameters—inductance, current rating, saturation current, and DC resistance—are identical. Physical dimensions and mounting characteristics are equivalent, ensuring PCB layout compatibility without redesign.

The CDEP105NP-5R0MC-50 offers two significant advantages over the main part:

Product Status: The substitute is classified as Active, ensuring continued availability and supply chain reliability.
Regulatory Compliance: The substitute achieves ROHS3 compliance, whereas the main part is non-compliant. This distinction is material for applications subject to RoHS regulations.
Packaging: The substitute is supplied in standard Tape & Reel format, facilitating automated assembly processes typical in production environments.

Selection of the CDEP105NP-5R0MC-50 is appropriate for all applications currently using or requiring the CDEP105-5R0MC-50, with the added benefit of regulatory compliance and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the CDEP105NP-5R0MC-50 be used as a direct replacement for the CDEP105-5R0MC-50?

A: Yes. All electrical specifications—inductance value, current rating, saturation current, and DC resistance—are identical. Physical dimensions and mounting type are equivalent, permitting direct substitution without circuit modification or PCB redesign.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. The CDEP105-5R0MC-50 is obsolete and supplied in nonstandard packaging. The CDEP105NP-5R0MC-50 is an active product supplied in Tape & Reel format and meets ROHS3 compliance requirements.

Q: Are there any compliance differences between these parts?

A: Yes. The CDEP105-5R0MC-50 is RoHS non-compliant. The CDEP105NP-5R0MC-50 is ROHS3 compliant. For applications subject to RoHS regulations, the substitute part is required.

Q: Will the Tape & Reel packaging of the substitute affect assembly?

A: No. Tape & Reel is the standard packaging format for surface mount components in automated assembly environments. It is compatible with standard pick-and-place equipment and does not affect component performance or reliability.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 10.00 mm length x 10.00 mm width with a maximum seated height of 5.60 mm. PCB footprints and mounting locations are identical.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
