Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDH63NP-150MC is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 15 µH (tolerance variance acceptable within design margin)
• Mounting type: Surface Mount
• Inductance test frequency: 100 kHz
• Shielding type: Unshielded
• Package form factor: Nonstandard drum core or wirewound construction

Performance Compatibility Parameters:

• Current rating must equal or exceed 780 mA
• Saturation current (Isat) must equal or exceed 1.1 A
• DC resistance must not exceed 275 mOhm
• Physical dimensions must accommodate PCB layout constraints

The substitute part B82462A4153K000 meets all critical matching parameters and exceeds performance specifications in current rating (900 mA vs. 780 mA), saturation current (1.5 A vs. 1.1 A), and provides superior DC resistance (210 mOhm vs. 275 mOhm maximum). Physical dimensions are comparable within standard PCB assembly tolerances.

Engineering Selection Recommendations

Primary Substitute: B82462A4153K000

The B82462A4153K000 is the qualified substitute for the obsolete CDH63NP-150MC based on the following engineering criteria:

1. Electrical Equivalence: Both components provide 15 µH inductance at 100 kHz test frequency. The substitute's tighter tolerance (±10% vs. ±20%) provides improved circuit performance predictability.

2. Current Capacity: The substitute's 900 mA rating exceeds the original 780 mA requirement, providing design margin. Saturation current of 1.5 A vs. 1.1 A offers additional headroom for transient conditions.

3. DC Resistance Performance: The substitute's 210 mOhm maximum DCR is superior to the original 275 mOhm specification, reducing power dissipation and thermal stress in the application.

4. Compliance and Certification: Both parts are ROHS3 compliant with MSL Level 1 rating. The substitute carries AEC-Q200 automotive qualification, indicating enhanced reliability screening and process control.

5. Product Status: The substitute is actively manufactured by EPCOS - TDK Electronics, ensuring long-term availability and supply chain continuity, contrasting with the obsolete status of the original part.

6. Physical Compatibility: Package dimensions are comparable (6.00 × 6.00 × 3.00 mm vs. 6.30 × 6.10 × 2.90 mm), accommodating standard PCB assembly processes with minimal layout adjustment.

7. Operating Temperature: The substitute specifies -55°C to 150°C operating range, suitable for industrial and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can B82462A4153K000 be used as a direct replacement for CDH63NP-150MC?

A: Yes. Both components share identical 15 µH inductance at 100 kHz test frequency, unshielded construction, and surface-mount configuration. The substitute meets or exceeds all electrical performance parameters of the original part. Physical dimensions are comparable within standard PCB assembly tolerances.

Q: What are the key differences between these two inductors?

A: The substitute provides superior electrical performance: tighter inductance tolerance (±10% vs. ±20%), higher current rating (900 mA vs. 780 mA), higher saturation current (1.5 A vs. 1.1 A), and lower DC resistance (210 mOhm vs. 275 mOhm maximum). The substitute is actively manufactured with AEC-Q200 qualification, while the original is obsolete.

Q: Are there any package compatibility concerns?

A: Package dimensions differ slightly: B82462A4153K000 measures 6.00 × 6.00 × 3.00 mm versus CDH63NP-150MC at 6.30 × 6.10 × 2.90 mm. These differences are within standard PCB assembly tolerances and do not present compatibility issues for typical surface-mount applications.

Q: Does the substitute have the same moisture sensitivity rating?

A: Yes. Both components carry MSL Level 1 (Unlimited) rating, indicating identical moisture sensitivity classification and handling requirements.

Q: Is the substitute suitable for automotive applications?

A: The substitute B82462A4153K000 carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The original CDH63NP-150MC does not specify automotive qualification.

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

A: Lower DC resistance (210 mOhm vs. 275 mOhm) reduces resistive power dissipation in the inductor, resulting in lower operating temperature and improved efficiency. This is a performance advantage with no negative impact on circuit function.

Q: Are both parts RoHS compliant?

A: Yes. Both CDH63NP-150MC and B82462A4153K000 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: Why is the original part obsolete?

A: The CDH63NP-150MC is classified as obsolete by the manufacturer. The B82462A4153K000 is the active equivalent from EPCOS - TDK Electronics, ensuring continued availability and manufacturing support.
