Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDRH62NP-560MC is determined by the following critical parameters:

Inductance Value: 56 µH with ±20% tolerance establishes the primary electrical requirement. Substitute parts must maintain this inductance specification.

Current Rating: The main part supports 520 mA. Substitute parts with equal or higher current ratings satisfy this requirement. The SPD62R-563M provides 680 mA, exceeding the original specification.

DC Resistance: Maximum 850 mOhm DCR is a critical performance parameter. Substitute parts must not exceed this value to maintain equivalent circuit behavior.

Physical Dimensions: The footprint of 0.260" L x 0.244" W (6.60mm x 6.20mm) with maximum height of 0.118" (3.00mm) must be preserved for PCB layout compatibility.

Mounting Type: Surface mount configuration is mandatory for compatibility with existing assembly processes.

Environmental Compliance: RoHS3 compliance and MSL Level 1 rating are required for regulatory and manufacturing compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SPD62R-563M from API Delevan Inc. is a direct functional equivalent to the obsolete CDRH62NP-560MC. Both components meet the critical electrical specifications: 56 µH inductance, 850 mOhm maximum DC resistance, and surface mount configuration with identical physical dimensions.

The SPD62R-563M provides enhanced performance characteristics in three areas:

Current Rating: The substitute supports 680 mA versus the original 520 mA, providing 31% additional current capacity while maintaining the same DC resistance specification.

Operating Temperature Range: The substitute operates from -55°C to 125°C, extending the lower temperature limit by 15°C and the upper limit by 25°C compared to the original -40°C to 100°C range.

Shielding: The substitute incorporates shielding, whereas the original is unshielded. This provides electromagnetic interference mitigation in applications where such protection is beneficial.

Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and manufacturing process compatibility. The substitute is in active production status, providing long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the SPD62R-563M replace the CDRH62NP-560MC in existing designs?

A: Yes. The SPD62R-563M meets all critical electrical and physical parameters of the CDRH62NP-560MC. Identical inductance value (56 µH), DC resistance (850 mOhm max), current rating (680 mA exceeds 520 mA requirement), and physical footprint (0.260" x 0.244" x 0.118" max height) ensure direct substitution compatibility.

Q: What is the impact of the shielded design of the SPD62R-563M?

A: The SPD62R-563M incorporates shielding, while the CDRH62NP-560MC is unshielded. Shielding reduces electromagnetic field radiation and susceptibility to external interference. This is an enhancement that does not compromise compatibility with the original design.

Q: Are there any temperature range considerations?

A: The SPD62R-563M operates from -55°C to 125°C, compared to the original -40°C to 100°C. The substitute provides extended temperature capability in both directions, making it suitable for applications with more demanding thermal requirements.

Q: Do both parts have identical packaging and mounting?

A: Yes. Both components are surface mount inductors with nonstandard package designation, identical physical dimensions of 0.260" L x 0.244" W (6.60mm x 6.20mm), and maximum seated height of 0.118" (3.00mm). PCB layout and assembly processes require no modification.

Q: What is the significance of the product status difference?

A: The CDRH62NP-560MC is obsolete, meaning Sumida America Components Inc. no longer manufactures this part. The SPD62R-563M is in active production status, ensuring continued availability, consistent quality, and long-term supply chain support.

Q: Are compliance certifications equivalent?

A: Yes. Both components are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. No additional compliance verification is required for substitution.
