Substitute Part Grouping Explanation

Substitution eligibility for the MBH6045C-470MB=P3 is determined by the following critical parameters:

• Inductance Value: 47 µH with ±20% tolerance
• Current Rating: Minimum 970 mA (substitute must support the application's current requirements)
• DC Resistance: 156 mOhm maximum (electrical loss characteristic)
• Core Type & Shielding: Ferrite drum core, shielded configuration
• Mounting: Surface mount, nonstandard package
• Test Frequency: 100 kHz
• Compliance: AEC-Q200 qualification and ROHS3 compliance

The CLF6045NIT-470M-D from TDK Corporation meets all substitution criteria. While the current rating is specified as 970 mA (compared to 1.1 A for the original), the saturation current (Isat) is rated at 970 mA, and the DC resistance matches at 156 mOhm maximum. Both parts share identical inductance, tolerance, core material, shielding, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CLF6045NIT-470M-D is a direct functional substitute for the obsolete MBH6045C-470MB=P3. Both components maintain identical electrical specifications for inductance, tolerance, DC resistance, and core configuration. The substitute part carries active product status with established supply availability (5200 pcs in stock versus 771 pcs for the original), ensuring long-term procurement reliability.

Both parts satisfy AEC-Q200 automotive qualification and ROHS3 compliance requirements. The TDK substitute provides an explicit operating temperature range of -55°C to 150°C, whereas the original specification does not document this parameter. The saturation current of the substitute (970 mA) exceeds the original's specification (740 mA), providing improved performance margin in this characteristic.

Selection should account for application current requirements. If the circuit operates at or below 970 mA continuous current, the substitute is fully qualified. Applications requiring the full 1.1 A rating of the original part require circuit-level evaluation to confirm compatibility with the substitute's 970 mA specification.

Frequently Asked Questions (FAQ)

Q: Can the CLF6045NIT-470M-D replace the MBH6045C-470MB=P3 in existing designs?

A: Yes, provided the application current does not exceed 970 mA continuous. The inductance value, tolerance, DC resistance, core material, shielding, and compliance certifications are identical. Both parts are rated for 100 kHz test frequency and carry AEC-Q200 qualification.

Q: What is the difference in current ratings between these parts?

A: The original MBH6045C-470MB=P3 is rated for 1.1 A continuous current with a saturation current of 740 mA. The CLF6045NIT-470M-D is rated for 970 mA continuous current with a saturation current of 970 mA. The substitute's higher saturation current provides better performance margin in this parameter.

Q: Are the physical dimensions compatible?

A: Both parts are nonstandard package surface mount inductors with similar footprints. The MBH6045C measures 0.244" L x 0.244" W (6.20mm x 6.20mm) with 0.189" height. The CLF6045NIT-470M-D measures 0.248" L x 0.236" W (6.30mm x 6.00mm) with 0.189" height. Dimensional differences are minimal and within typical PCB layout tolerances for surface mount placement.

Q: Do both parts meet automotive standards?

A: Yes. Both the MBH6045C-470MB=P3 and CLF6045NIT-470M-D carry AEC-Q200 qualification, confirming suitability for automotive applications.

Q: What is the packaging format for the substitute?

A: The CLF6045NIT-470M-D is supplied in Cut Tape (CT) packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are there any compliance or environmental differences?

A: Both parts are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level). The substitute provides an explicit operating temperature range of -55°C to 150°C. Both carry EAR99 ECCN classification.
