Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDEP105-7R2MC-88 is determined by strict equivalence across the following critical parameters:

Inductance Value & Tolerance: The substitute must provide 7.2 µH ±20% inductance measured at 100 kHz to maintain circuit performance within design specifications.

Current Handling Capability: Both continuous current rating (6.2 A) and saturation current (5.3 A) must be matched to ensure the inductor operates within safe thermal and magnetic limits under load conditions.

DC Resistance: Maximum DCR of 18 mOhm must be maintained to prevent excessive power dissipation and heat generation in the application circuit.

Core Construction & Shielding: Ferrite drum core with shielding must be preserved to maintain electromagnetic compatibility and prevent coupling with adjacent circuit elements.

Physical Form Factor: Surface mount package with dimensions 10.00 mm x 10.00 mm x 5.60 mm (max height) ensures mechanical compatibility with existing PCB layouts and assembly processes.

Operating Temperature Range: The -40°C to 125°C specification must be supported to guarantee reliability across the full application environment.

Parameter Comparison

Engineering Selection Recommendations

The CDEP105NP-7R2MC-88 is the direct functional equivalent of the CDEP105-7R2MC-88. All electrical and mechanical parameters are identical, ensuring drop-in compatibility at the circuit level.

Product Status Advantage: The substitute part carries Active product status, whereas the main part is classified as Obsolete. This distinction is critical for long-term supply chain reliability and future production planning.

Regulatory Compliance: The CDEP105NP-7R2MC-88 achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies current environmental and material restriction directives.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The original part packaging format is not specified in detail. TR packaging is compatible with standard pick-and-place equipment and provides better handling and storage characteristics for production environments.

Inventory & Availability: The substitute part has 2216 pieces in stock compared to 843 pieces for the original part, indicating superior availability for immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can CDEP105NP-7R2MC-88 be used as a direct replacement for CDEP105-7R2MC-88 in existing designs?

A: Yes. All electrical specifications (inductance, current rating, DC resistance, saturation current) and mechanical dimensions are identical. The substitute part is electrically and mechanically interchangeable at the circuit board level.

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

A: The primary differences are product status (Active vs. Obsolete), RoHS compliance (ROHS3 Compliant vs. non-compliant), and packaging format (Tape & Reel vs. unspecified bulk format). The electrical and physical characteristics are identical.

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

A: No. Tape & Reel is a supply format only and does not affect the component's electrical or thermal performance once soldered to the PCB. It is the standard packaging format for automated assembly operations.

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

A: No. The CDEP105NP-7R2MC-88 operates across the identical temperature range (-40°C to 125°C) and is specified at the same inductance test frequency (100 kHz) as the original part.

Q: Why should I choose the substitute part over the original?

A: The substitute part is Active (not Obsolete), ensuring long-term availability and supply chain continuity. It also meets ROHS3 compliance requirements, which may be mandated by customer specifications or regulatory requirements in your target markets.

Q: Is the ±20% inductance tolerance maintained in the substitute part?

A: Yes. Both parts specify ±20% inductance tolerance, ensuring equivalent circuit performance and design margin.

Q: Can I mix the original and substitute parts in the same production batch?

A: Yes. Since all electrical and mechanical parameters are identical, both parts can be used interchangeably within the same design without affecting circuit performance or reliability.
