CLF10040T-151M-D Equivalent & Substitute Parts

Part Overview

The CLF10040T-151M-D is a 150 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 800 mA continuous current with a maximum DC resistance of 456mOhm. This surface mount component is designed for applications requiring compact, shielded inductance in the 150 µH range with ferrite core construction and AEC-Q200 automotive qualification.

The part is currently in active production status with 1,463 units in stock. Substitute parts may be required due to design optimization, current rating requirements, or supply chain considerations while maintaining the same inductance value and core shielding characteristics.

Key Parameters

Substitute Part Grouping Explanation

The CLF10060NIT-151M-D qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• Inductance: 150 µH (identical)
• Inductance Tolerance: ±20% (identical)
• Core Material: Ferrite (identical)
• Shielding: Shielded (identical)
• Mounting Type: Surface Mount (identical)
• Inductance Test Frequency: 100 kHz (identical)
• AEC-Q200 Qualification: Yes (identical)
• RoHS3 Compliance: Yes (identical)
• REACH Status: Unaffected (identical)

Allowable Variations:

• Current Rating: Increased from 800 mA to 1.05 A (higher rating acceptable for same inductance)
• DC Resistance: Reduced from 456mOhm to 288mOhm (lower resistance acceptable)
• Operating Temperature Range: Extended from -40°C to -55°C minimum (wider range acceptable)
• Physical Dimensions: Minor variations within nonstandard package specifications

Engineering Selection Recommendations

CLF10040T-151M-D (Main Part):

• Recommended for new designs requiring active production status and long-term availability
• Suitable for applications with 800 mA maximum current requirements
• Preferred when space constraints limit component height to 4.10mm maximum
• Current inventory of 1,463 units supports immediate procurement

CLF10060NIT-151M-D (Substitute Part):

• Acceptable for applications where current rating of 1.05 A meets or exceeds design requirements
• Provides lower DC resistance (288mOhm vs 456mOhm), reducing power dissipation
• Extended operating temperature range (-55°C minimum) suitable for wider environmental specifications
• Note: Product status is Last Time Buy; verify long-term availability before design commitment
• Requires verification of PCB layout compatibility due to increased height (6.30mm vs 4.10mm)

Both parts maintain identical inductance, tolerance, core material, shielding, and AEC-Q200 automotive qualification, ensuring functional equivalence within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can CLF10060NIT-151M-D replace CLF10040T-151M-D in existing designs?

A: Yes, provided the application can accommodate the increased component height (6.30mm vs 4.10mm) and the higher current rating (1.05 A vs 800 mA) does not introduce thermal or performance concerns. Both parts deliver identical 150 µH inductance with ±20% tolerance and maintain AEC-Q200 qualification.

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

A: The CLF10060NIT-151M-D exhibits 288mOhm maximum DC resistance compared to 456mOhm in the main part. This reduction decreases resistive losses and power dissipation, which may improve circuit efficiency. Verify that the lower resistance does not alter circuit behavior in current-limiting or impedance-critical applications.

Q: Are there packaging differences between these parts?

A: Both parts use nonstandard surface mount packages with minor dimensional variations. The main part measures 10.00mm L x 9.70mm W x 4.10mm H, while the substitute measures 10.10mm L x 10.00mm W x 6.30mm H. Confirm PCB layout and component placement clearances before substitution.

Q: What does "Last Time Buy" status mean for the substitute part?

A: Last Time Buy indicates that CLF10060NIT-151M-D is in the final production phase with no planned continuation. Existing inventory of 9,068 units is available, but future procurement may not be possible. For long-term production designs, the active status CLF10040T-151M-D is recommended.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CLF10040T-151M-D and CLF10060NIT-151M-D are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Can the substitute part operate at lower temperatures than the main part?

A: Yes. The CLF10060NIT-151M-D operates from -55°C to 150°C, extending the lower temperature limit by 15°C compared to the main part's -40°C to 150°C range. This wider operating window may be beneficial for applications in extreme cold environments.
