Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDH63NP-151KC is determined by the following critical parameters:

Inductance Value: 150 µH with ±10% tolerance is the primary electrical requirement. Substitute parts must maintain this inductance specification.

Current Handling: The main part supports 230 mA continuous current with 310 mA saturation current. Substitute parts must meet or exceed these current ratings to ensure equivalent or superior performance in the application circuit.

DC Resistance: The 3.24 Ohm maximum DCR is a key thermal and efficiency parameter. Substitute parts with lower DCR values provide improved performance characteristics.

Physical Form Factor: Surface mount nonstandard package with unshielded configuration. Substitute parts must be compatible with surface mount assembly processes.

Environmental Compliance: RoHS3 compliance and MSL 1 rating are mandatory for modern manufacturing and storage requirements.

The B82462A4154K000 qualifies as a substitute based on matching inductance value, exceeding current ratings, maintaining unshielded configuration, and meeting all compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The B82462A4154K000 is a direct functional substitute for the obsolete CDH63NP-151KC based on the following engineering criteria:

Electrical Equivalence: Both parts maintain 150 µH inductance at ±10% tolerance and 100 kHz test frequency. The substitute part exceeds the current rating requirement (290 mA vs. 230 mA) and provides superior saturation current margin (490 mA vs. 310 mA).

Thermal Performance: The B82462A4154K000 exhibits lower DC resistance (1.76 Ohm vs. 3.24 Ohm), resulting in reduced power dissipation and improved thermal efficiency in the application circuit.

Compliance and Availability: The substitute part is active in production with full RoHS3 compliance, MSL 1 rating, and AEC-Q200 automotive qualification. The CDH63NP-151KC is obsolete, making the B82462A4154K000 the appropriate selection for new designs and ongoing procurement.

Physical Compatibility: Both parts are surface mount nonstandard packages with unshielded configuration, supporting equivalent assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the B82462A4154K000 directly replace the CDH63NP-151KC in existing designs?

A: Yes. Both parts share identical inductance value (150 µH), tolerance (±10%), test frequency (100 kHz), and mounting type (surface mount). The substitute part meets or exceeds all electrical performance parameters of the original component.

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

A: The B82462A4154K000 has 1.76 Ohm maximum DCR compared to 3.24 Ohm in the CDH63NP-151KC. Lower DCR reduces resistive losses, decreases heat generation, and improves overall circuit efficiency. This represents an improvement over the original specification.

Q: Are there any current rating limitations when using the substitute?

A: No. The B82462A4154K000 is rated for 290 mA continuous current and 490 mA saturation current, both exceeding the original part's 230 mA and 310 mA ratings. The substitute part provides additional current handling margin.

Q: Does the substitute part have automotive qualification?

A: Yes. The B82462A4154K000 carries AEC-Q200 qualification, indicating suitability for automotive applications. The original CDH63NP-151KC does not specify automotive qualification.

Q: Are the physical dimensions compatible?

A: Both parts are nonstandard surface mount packages. The CDH63NP-151KC measures 0.248" L x 0.240" W x 0.114" H (6.30mm x 6.10mm x 2.90mm). The B82462A4154K000 measures 0.236" L x 0.236" W x 0.118" H (6.00mm x 6.00mm x 3.00mm). Dimensions are similar and compatible with standard surface mount assembly equipment.

Q: What is the operating temperature range for the substitute part?

A: The B82462A4154K000 operates across -55°C to 150°C. The original CDH63NP-151KC does not specify an operating temperature range in the provided data.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CDH63NP-151KC and B82462A4154K000 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting modern manufacturing and environmental requirements.
