Frequently Asked Questions (FAQ)

Q: Are the CDEP105-0R8MC-88 and CDEP105NP-0R8MC-88 electrically identical?

A: Yes. Both parts have identical inductance (800 nH), tolerance (±20%), current rating (17.7 A), saturation current (16 A), and DC resistance (2.4 mOhm max). They are electrically interchangeable.

Q: Can I use CDEP105NP-0R8MC-88 as a direct replacement on existing PCBs designed for CDEP105-0R8MC-88?

A: Yes. The parts share identical footprints (10.00 mm x 10.00 mm) and maximum seated height (5.60 mm). Direct PCB substitution is possible without layout modifications.

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

A: The primary differences are product status and compliance. CDEP105-0R8MC-88 is obsolete and RoHS non-compliant. CDEP105NP-0R8MC-88 is active and ROHS3 compliant. The "NP" designation in the substitute part number indicates the updated packaging and compliance status.

Q: Is the Tape & Reel packaging of CDEP105NP-0R8MC-88 compatible with my assembly process?

A: Tape & Reel (TR) is the standard packaging format for automated surface mount assembly. Compatibility depends on your specific assembly equipment. Verify that your pick-and-place system supports the component reel specifications.

Q: Why should I transition from CDEP105-0R8MC-88 to CDEP105NP-0R8MC-88?

A: The original part is obsolete, creating supply risk. The substitute is in active production, ensuring availability. Additionally, ROHS3 compliance aligns with current regulatory requirements and may be mandatory for certain end markets or customers.

Q: Are there any thermal or frequency performance differences between these parts?

A: No. Both parts operate across -40°C to 125°C and are tested at 100 kHz. Thermal and frequency characteristics are identical.
