Engineering Selection Recommendations

The CDEP105NP-2R5MC-50 is the direct equivalent substitute for the obsolete CDEP105-2R5MC-50. Selection of the substitute part is based on the following factors:

Product Status: The original part is classified as obsolete. The substitute maintains active product status, ensuring long-term availability and manufacturing continuity.

Electrical Equivalence: All electrical parameters are identical, including inductance value, current ratings, saturation characteristics, and DC resistance specifications. The parts are functionally interchangeable in circuit applications.

Compliance Certification: The substitute part carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. This upgrade in compliance status supports modern procurement requirements and regulatory standards.

Physical Compatibility: Identical package dimensions and surface mount configuration ensure direct mechanical compatibility with existing PCB layouts and assembly processes.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly operations. The original part was supplied in bulk packaging. This difference does not affect electrical or mechanical performance but may impact procurement and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can CDEP105NP-2R5MC-50 be used as a direct replacement for CDEP105-2R5MC-50?

A: Yes. The substitute part meets all electrical, mechanical, and environmental specifications of the original part. All critical parameters including inductance, current rating, DC resistance, core material, shielding, and package dimensions are identical.

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

A: The primary differences are product status and compliance certification. CDEP105-2R5MC-50 is obsolete and RoHS non-compliant. CDEP105NP-2R5MC-50 is active and ROHS3 compliant. The "NP" designation in the substitute part number indicates the updated compliance status. Electrical and mechanical specifications are identical.

Q: Does the packaging format change affect circuit performance?

A: No. The change from bulk to Tape & Reel (TR) packaging is a supply format difference only. It does not affect the electrical characteristics, performance, or reliability of the inductor component itself.

Q: Are the inductance values and tolerances identical?

A: Yes. Both parts are rated at 2.5 µH with ±20% tolerance, measured at 100 kHz test frequency. They are electrically equivalent for inductance specifications.

Q: Can these parts be used interchangeably in high-current applications?

A: Yes. Both parts have identical current ratings of 7.8 A continuous and 11.8 A saturation current. They are fully equivalent for current handling capacity.

Q: What is the significance of the RoHS compliance upgrade?

A: ROHS3 compliance indicates the substitute part meets current environmental and hazardous substance restrictions. This is important for applications subject to regulatory requirements and modern procurement standards. The original non-compliant part may face restrictions in certain markets or applications.

Q: Are the operating temperature ranges the same?

A: Yes. Both parts operate across -40°C to 125°C. Temperature performance is identical.

Q: Is the shielding configuration the same?

A: Yes. Both parts feature shielded drum core construction, providing identical electromagnetic shielding characteristics.
