Parameter Comparison

Engineering Selection Recommendations

The CDEP105NP-2R0MC-32 is the direct equivalent substitute for the obsolete CDEP105-2R0MC-32. All electrical and mechanical parameters are identical, ensuring functional compatibility in circuit applications.

Primary Advantage: The substitute part carries Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance Improvement: The CDEP105NP-2R0MC-32 is RoHS3 compliant, whereas the main part is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic components in regulated markets.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) packaging, which differs from the nonstandard packaging of the main part. Tape & Reel packaging is standard for automated assembly processes and provides improved handling and storage characteristics.

Inventory Status: The substitute part has 747 pieces in new original stock, providing immediate procurement availability.

Frequently Asked Questions (FAQ)

Q: Can CDEP105NP-2R0MC-32 be used as a direct replacement for CDEP105-2R0MC-32?

A: Yes. The substitute part is electrically and mechanically identical across all specified parameters, including inductance, current rating, DC resistance, core material, shielding, operating temperature range, and package dimensions. Direct substitution is supported.

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

A: The primary differences are product status and compliance. CDEP105-2R0MC-32 is obsolete and RoHS non-compliant, while CDEP105NP-2R0MC-32 is active and RoHS3 compliant. The packaging format also differs: the main part uses nonstandard packaging, while the substitute uses Tape & Reel (TR) packaging.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel packaging is a supply and handling format only. It does not affect the electrical or mechanical characteristics of the component itself. The inductor specifications remain identical.

Q: Are there any temperature or frequency limitations with the substitute part?

A: No. The substitute part operates across the identical temperature range of -40°C to 125°C and is tested at 100 kHz, matching the main part specifications.

Q: Is the RoHS3 compliance of the substitute part a requirement for my application?

A: RoHS3 compliance is a regulatory requirement in many markets, particularly for products sold in the European Union and other regulated regions. If your application or end market requires RoHS compliance, the substitute part meets this requirement while the main part does not.

Q: What is the saturation current specification, and why is it important?

A: The saturation current (Isat) of 15.8 A indicates the maximum current level before the inductor's core saturates and inductance degrades. Both parts are identical at this specification. This parameter is critical for applications requiring current headroom above the 7.4 A continuous rating.

Q: Can I mix inventory of both part numbers in production?

A: Both parts are electrically and mechanically equivalent. However, from a supply chain and compliance perspective, transitioning to the active substitute part (CDEP105NP-2R0MC-32) is recommended to ensure long-term availability and regulatory compliance.
