MBH6045C-101MB=P3 Equivalent & Substitute Parts

Part Overview

The MBH6045C-101MB=P3 is a 100 µH shielded drum core wirewound inductor manufactured by Murata Electronics, rated for 830 mA continuous current with a maximum DC resistance of 408 mOhm. This surface mount component is designed for applications requiring stable inductance performance at 100 kHz test frequency with ferrite core construction and AEC-Q200 qualification.

The MBH6045C series has reached obsolete product status. Identifying qualified substitute parts ensures design continuity and maintains supply chain reliability for applications currently using this inductor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBH6045C-101MB=P3 is determined by the following critical parameters:

• Inductance Value: Must be 100 µH with ±20% tolerance
• Current Rating: Substitute must support minimum 830 mA continuous current
• DC Resistance: Maximum 408 mOhm to maintain thermal and efficiency characteristics
• Core Type: Ferrite drum core construction with shielding
• Mounting: Surface mount configuration
• Physical Dimensions: Compatible with 6.20mm x 6.20mm footprint and 4.80mm maximum height
• Compliance: AEC-Q200 qualification and ROHS3 compliance required

The CLF6045NIT-101M-D from TDK Corporation meets these substitution criteria within the allowed parameter ranges for this product category.

Parameter Comparison

Engineering Selection Recommendations

The CLF6045NIT-101M-D qualifies as a direct substitute based on the following factors:

• Both components maintain identical inductance value and tolerance at the 100 kHz test frequency
• Physical dimensions are compatible with the original PCB footprint and assembly process
• Both components carry AEC-Q200 qualification, meeting automotive-grade reliability standards
• Both components are ROHS3 compliant and carry MSL 1 rating
• The substitute features improved DC resistance (384 mOhm vs. 408 mOhm), reducing thermal dissipation
• The substitute is currently in active production status, ensuring long-term supply availability

The primary design consideration is the current rating differential: the substitute is rated for 610 mA continuous current versus the original 830 mA. Applications operating below 610 mA continuous current can use this substitute without derating. Applications requiring the full 830 mA rating must evaluate alternative solutions or confirm that peak current requirements do not exceed the substitute's saturation current of 610 mA.

Frequently Asked Questions (FAQ)

Q: Can the CLF6045NIT-101M-D replace the MBH6045C-101MB=P3 in all applications?

A: The CLF6045NIT-101M-D is electrically and mechanically compatible for applications operating at or below 610 mA continuous current. Applications requiring sustained current above 610 mA must evaluate alternative parts or confirm that actual operating current remains within the substitute's rating.

Q: Are there physical footprint differences between these parts?

A: The footprint dimensions are compatible. The original measures 6.20mm x 6.20mm while the substitute measures 6.30mm x 6.00mm. Both components have identical maximum seated height of 4.80mm and are designed for the same surface mount assembly process.

Q: What compliance certifications apply to both parts?

A: Both the MBH6045C-101MB=P3 and CLF6045NIT-101M-D carry AEC-Q200 qualification, ROHS3 compliance, and MSL 1 (unlimited moisture sensitivity level) rating.

Q: Why is the original part obsolete?

A: The MBH6045C series has reached end-of-life status. The CLF6045NIT-101M-D from TDK Corporation is an active production alternative that meets the same electrical and mechanical specifications within the allowed parameter ranges.

Q: How do the DC resistance values compare?

A: The substitute CLF6045NIT-101M-D features lower DC resistance at 384 mOhm maximum compared to 408 mOhm maximum for the original part. This represents an improvement in thermal efficiency and power dissipation characteristics.

Q: What is the saturation current difference?

A: The original part has saturation current (Isat) of 530 mA, while the substitute has 610 mA. The substitute's higher saturation current provides additional margin in peak current handling, though the continuous current rating remains the limiting factor for sustained operation.
