Engineering Selection Recommendations

The CDEP105NP-4R0MC-50 is the direct substitute for the obsolete CDEP105-4R0MC-50. All electrical, mechanical, and environmental parameters are identical. The substitute part carries an active product status, ensuring ongoing availability and supply chain support.

The CDEP105NP-4R0MC-50 provides an additional compliance advantage: it meets ROHS3 requirements, whereas the original part is RoHS non-compliant. This upgrade in regulatory compliance may be beneficial for new designs or systems subject to RoHS directives.

Both parts share identical inductance values, current ratings, DC resistance specifications, core materials, shielding characteristics, and physical dimensions. Footprint compatibility and electrical performance are fully preserved in the substitution.

Frequently Asked Questions (FAQ)

Q: Can the CDEP105NP-4R0MC-50 be used as a direct replacement for the CDEP105-4R0MC-50?

A: Yes. The CDEP105NP-4R0MC-50 is a direct substitute. All electrical parameters (inductance, current rating, DC resistance), mechanical dimensions, and environmental specifications are identical. The substitute part is currently in active production status.

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

A: The primary difference is product status: the CDEP105-4R0MC-50 is obsolete, while the CDEP105NP-4R0MC-50 is active. Additionally, the substitute part meets ROHS3 compliance, whereas the original part is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions and footprints identical?

A: Yes. Both parts measure 10.00 mm x 10.00 mm with a maximum seated height of 5.60 mm. Package type, mounting method, and PCB footprint are identical.

Q: Will the substitute part perform identically in my circuit?

A: Yes. The inductance value (4 µH), current rating (6.2 A), DC resistance (18 mOhm Max), saturation current (9.3 A), and operating temperature range (-40°C to 125°C) are identical. Electrical performance is equivalent.

Q: Is the substitute part available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Does the improved RoHS compliance of the substitute part affect performance?

A: No. ROHS3 compliance is a material composition specification that does not alter electrical or mechanical performance. The substitute part maintains identical functional characteristics while meeting enhanced regulatory requirements.
