Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDH63NP-220MC must satisfy the following criteria based on allowed electrical and mechanical parameters:

Mandatory Matching Parameters:

• Inductance: 22 µH (exact match required)
• Mounting Type: Surface Mount
• Shielding: Unshielded
• Inductance Test Frequency: 100 kHz

Allowable Variation Parameters:

• Current Rating: Must be ≥700 mA (substitute may exceed this specification)
• DC Resistance (DCR): Must be ≤450 mOhm (lower values are acceptable)
• Current - Saturation (Isat): Must be ≥850 mA (higher values are acceptable)
• RoHS Status: Must maintain ROHS3 Compliance

The B82462A4223K000 qualifies as a substitute because it maintains identical inductance, mounting type, shielding configuration, and test frequency while providing improved electrical performance through lower DCR, higher current rating, and higher saturation current.

Parameter Comparison

Engineering Selection Recommendations

The B82462A4223K000 is a qualified substitute for the CDH63NP-220MC based on the following engineering factors:

Electrical Compatibility: The substitute maintains the 22 µH inductance specification and operates at the same 100 kHz test frequency. The lower DC resistance (260 mOhm vs. 450 mOhm) reduces power dissipation and thermal generation. The higher current rating (800 mA vs. 700 mA) and saturation current (1.28 A vs. 850 mA) provide additional operational margin.

Regulatory and Compliance Status: Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental qualification and handling requirements.

Product Availability: The CDH63NP-220MC is obsolete with limited remaining inventory. The B82462A4223K000 is in active production status with substantial inventory availability (4508 pcs), supporting long-term supply chain continuity.

Physical Compatibility: The substitute dimensions (6.00mm x 6.00mm footprint, 3.00mm height) are comparable to the original (6.30mm x 6.10mm footprint, 2.90mm height). PCB layout verification is required to confirm clearance compatibility in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the B82462A4223K000 directly replace the CDH63NP-220MC in existing designs?

A: The B82462A4223K000 is electrically compatible as a substitute. The inductance value, test frequency, and shielding configuration are identical. Physical dimensions are comparable but require PCB layout verification due to minor footprint and height differences. No circuit redesign is necessary if PCB clearance is confirmed.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The B82462A4223K000 has a maximum DC resistance of 260 mOhm compared to 450 mOhm in the original. This 42% reduction in resistance decreases I²R power losses and thermal generation during operation, improving efficiency and thermal performance in the application.

Q: Does the tighter tolerance of the substitute part affect circuit performance?

A: The B82462A4223K000 has ±10% inductance tolerance versus ±20% for the CDH63NP-220MC. Tighter tolerance provides more predictable inductance values and may improve circuit performance consistency, but does not create incompatibility with designs specified for ±20% tolerance.

Q: Are there packaging differences between these parts?

A: The CDH63NP-220MC is supplied in standard packaging. The B82462A4223K000 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Reel format does not affect component electrical or mechanical specifications.

Q: What certifications does the substitute part carry?

A: The B82462A4223K000 carries AEC-Q200 qualification, which is an automotive electronics reliability standard. This certification is not listed for the original CDH63NP-220MC. Both parts are ROHS3 compliant and REACH unaffected.

Q: Is the slightly larger height of the substitute part a concern?

A: The substitute is 0.10mm taller (3.00mm vs. 2.90mm). This difference is negligible for most applications but should be verified in designs with strict height constraints or where components are mounted near other tall components.
