Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDRH62NP-680MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 68 µH with ±20% tolerance
• Mounting type: Surface Mount
• Package classification: Nonstandard
• Inductance test frequency: 2.52 MHz

Secondary Compatibility Factors:

• Current rating: Substitute must support minimum 490 mA
• DC resistance: Substitute DCR must not exceed 1.21 Ohm significantly
• Operating temperature: Substitute range must encompass or exceed -40°C to 100°C
• RoHS compliance: ROHS3 Compliant status required
• Moisture sensitivity: MSL 1 classification

The two identified substitute parts meet these criteria with variations in shielding configuration, current capacity, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

IDCP1813ER680M (Vishay Dale): This substitute maintains unshielded configuration matching the original CDRH62NP-680MC. The part is currently in active production status with ROHS3 compliance and MSL 1 rating. The DC resistance of 1.117 Ohm is lower than the main part specification, providing improved efficiency characteristics. Current rating of 460 mA is 30 mA below the original specification; this represents a constraint for applications requiring the full 490 mA capacity. Operating temperature range extends to 105°C, exceeding the original upper limit. Physical dimensions are significantly smaller (4.50mm x 4.00mm versus 6.60mm x 6.20mm), which may require PCB layout modification. Inductance test frequency matches at 2.52 MHz.

SPD62R-683M (API Delevan Inc.): This substitute provides shielded configuration, differing from the unshielded original design. The part is in active production with ROHS3 compliance and MSL 1 rating. Current rating of 560 mA exceeds the original 490 mA requirement by 70 mA, providing operational margin. DC resistance of 1.2 Ohm is within specification tolerance. Operating temperature range of -55°C to 125°C significantly exceeds the original -40°C to 100°C specification. Physical dimensions and height match the original part exactly (6.60mm x 6.20mm x 3.00mm), enabling direct PCB footprint compatibility. Inductance test frequency differs at 1 kHz versus the original 2.52 MHz. The shielded design may reduce electromagnetic interference in sensitive applications but introduces different magnetic field characteristics.

Selection between these substitutes depends on application-specific requirements regarding shielding necessity, current margin requirements, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can IDCP1813ER680M replace CDRH62NP-680MC in all applications?

A: IDCP1813ER680M meets the core electrical specifications of 68 µH inductance with ±20% tolerance and maintains unshielded configuration. However, the current rating of 460 mA is 30 mA lower than the original 490 mA specification. Applications operating at or near 490 mA continuous current cannot use this substitute. Additionally, the smaller physical footprint (4.50mm x 4.00mm versus 6.60mm x 6.20mm) requires PCB layout verification.

Q: What is the primary difference between the two substitute options?

A: The SPD62R-683M provides shielded construction with higher current capacity (560 mA) and identical physical dimensions to the original part, enabling direct footprint compatibility. The IDCP1813ER680M maintains unshielded construction but features a smaller package size and lower DC resistance. The shielding difference affects electromagnetic field containment and potential interference characteristics.

Q: Are both substitutes RoHS compliant?

A: Yes, both IDCP1813ER680M and SPD62R-683M are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original CDRH62NP-680MC specifications.

Q: Does the inductance test frequency difference between substitutes affect compatibility?

A: The IDCP1813ER680M uses 2.52 MHz test frequency matching the original part. The SPD62R-683M uses 1 kHz test frequency. Both maintain 68 µH inductance with ±20% tolerance at their respective test frequencies. Application compatibility depends on the frequency range of the circuit design. For circuits operating in the megahertz range, the matching test frequency of IDCP1813ER680M may provide closer performance correlation.

Q: Can SPD62R-683M be used in applications requiring unshielded inductors?

A: SPD62R-683M is shielded, which differs from the unshielded original design. Shielded inductors contain magnetic fields more effectively, reducing external electromagnetic interference. Applications specifically requiring unshielded construction should use IDCP1813ER680M. Applications where shielding is beneficial or neutral can use SPD62R-683M.

Q: What are the thermal operating range considerations?

A: The original CDRH62NP-680MC operates from -40°C to 100°C. IDCP1813ER680M extends to -25°C to 105°C, and SPD62R-683M extends to -55°C to 125°C. Both substitutes support the original temperature range. Applications requiring operation below -40°C must use SPD62R-683M. Applications requiring operation above 100°C can use either substitute.

Q: Are there physical footprint compatibility concerns?

A: SPD62R-683M matches the original dimensions exactly (6.60mm x 6.20mm x 3.00mm height), enabling direct PCB footprint compatibility. IDCP1813ER680M is significantly smaller (4.50mm x 4.00mm x 3.20mm height), requiring PCB layout modification and potential rerouting of adjacent traces and components.
