Substitute Part Grouping Explanation

Substitution of the CDEP63MENP-1R0MC is determined by strict equivalence across the following critical parameters:

Inductance Value: Both main and substitute parts must maintain 1 µH inductance at 100 kHz test frequency with ±20% tolerance to ensure circuit performance.

Current Rating: The substitute part must support the application's current requirements. The CDEP63MENP-1R0MC operates at 7.2 A; substitute parts with equal or higher current ratings are functionally compatible.

DC Resistance: Maximum DCR of 14 mOhm in the main part establishes the upper limit for acceptable power dissipation. Substitute parts with lower DCR values reduce thermal losses and improve efficiency.

Saturation Current: The main part saturates at 21.2 A. Substitute parts must maintain saturation characteristics suitable for the application's peak current conditions.

Shielding and Core Material: Both parts employ shielded construction with iron-based cores, maintaining electromagnetic compatibility and noise suppression characteristics.

Temperature Range: Operating range of -40°C to 125°C must be maintained across substitute selections.

Mounting and Compliance: Surface mount packaging, ROHS3 compliance, and MSL 1 rating ensure manufacturing and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SRP7030-1R0M from Bourns Inc. qualifies as a functional substitute for the obsolete CDEP63MENP-1R0MC based on the following engineering criteria:

Electrical Equivalence: Both inductors maintain 1 µH inductance at ±20% tolerance with 100 kHz test frequency. The SRP7030-1R0M provides 11 A current rating, exceeding the CDEP63MENP-1R0MC requirement of 7.2 A, ensuring adequate current capacity.

DC Resistance Performance: The SRP7030-1R0M exhibits 10 mOhm maximum DCR, superior to the main part's 14 mOhm specification, resulting in reduced power dissipation and improved thermal performance.

Saturation Characteristics: The SRP7030-1R0M saturates at 15 A compared to the main part's 21.2 A. Applications operating below 15 A peak current experience no functional degradation. Applications requiring peak currents between 15 A and 21.2 A require circuit-level evaluation.

Compliance and Supply: The SRP7030-1R0M maintains ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring manufacturing and environmental compatibility. Active production status at Bourns Inc. ensures continued availability.

Physical Considerations: The SRP7030-1R0M measures 7.80mm L x 7.00mm W x 3.20mm H (max seated), compared to 7.25mm L x 6.80mm W x 3.00mm H for the main part. PCB layout and clearance verification is required for applications with space constraints.

Frequently Asked Questions (FAQ)

Q: Can the SRP7030-1R0M directly replace the CDEP63MENP-1R0MC without circuit modification?

A: The SRP7030-1R0M is electrically compatible for applications operating at or below 7.2 A continuous current and 15 A peak saturation current. Physical dimensions are slightly larger; verify PCB layout accommodates the 7.80mm x 7.00mm x 3.20mm footprint.

Q: What is the significance of the saturation current difference between these parts?

A: The CDEP63MENP-1R0MC saturates at 21.2 A; the SRP7030-1R0M saturates at 15 A. Saturation defines the current level at which inductance degrades significantly. Applications with peak currents exceeding 15 A require evaluation of circuit performance under saturation conditions.

Q: Does the lower DC resistance of the SRP7030-1R0M provide any advantage?

A: Yes. The SRP7030-1R0M's 10 mOhm DCR compared to 14 mOhm reduces resistive losses by approximately 29%, lowering power dissipation and operating temperature. This improves efficiency and thermal margin in power-sensitive applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the CDEP63MENP-1R0MC and SRP7030-1R0M operate across -40°C to 125°C, maintaining equivalent thermal performance specifications.

Q: What packaging differences exist between these inductors?

A: The CDEP63MENP-1R0MC is supplied in standard packaging. The SRP7030-1R0M is supplied in Tape & Reel (TR) format, standard for high-volume manufacturing. Both are surface mount components with identical mounting compatibility.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings, ensuring equivalent compliance for manufacturing and environmental requirements.

Q: Why is the CDEP63MENP-1R0MC classified as obsolete?

A: Obsolescence reflects discontinuation by the original manufacturer, Sumida America Components Inc. The SRP7030-1R0M from Bourns Inc. maintains active production status, ensuring long-term supply availability.
