CLF10040T-2R2N-D Equivalent & Substitute Parts

Part Overview

The CLF10040T-2R2N-D is a 2.2 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 5 A continuous current with a maximum DC resistance of 12.61 mOhm. This surface mount component is designed for applications requiring fixed inductance in compact form factors with ferrite core shielding and AEC-Q200 automotive qualification.

The part is currently in active production status. Substitute parts become necessary when the original specification is unavailable, when inventory constraints require alternative sourcing, or when design requirements permit relaxed parameter tolerances within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLF10040T-2R2N-D is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±30% tolerance
• Core Type & Shielding: Ferrite core with shielding required
• Current Rating: Minimum 5 A continuous current capability
• DC Resistance: Lower or equal DCR values are acceptable
• Operating Temperature: Must support -40°C to 150°C range
• Compliance: AEC-Q200 automotive qualification required
• Mounting: Surface mount configuration mandatory

The CLF10060NIT-2R2N-D qualifies as a manufacturer-recommended substitute because it maintains identical inductance value and tolerance, ferrite core construction with shielding, AEC-Q200 compliance, and surface mount configuration. The substitute offers improved electrical performance through higher current rating (8.5 A vs 5 A) and lower DC resistance (9.23 mOhm vs 12.61 mOhm), with extended lower temperature operating range (-55°C vs -40°C).

Parameter Comparison

Engineering Selection Recommendations

The CLF10060NIT-2R2N-D is qualified as a direct substitute for the CLF10040T-2R2N-D based on electrical equivalence and compliance alignment. Both components maintain identical inductance specifications, ferrite core construction, shielding characteristics, and AEC-Q200 automotive qualification.

The substitute part provides superior electrical performance with 70% higher current rating and 27% lower DC resistance, making it suitable for applications where the original part's current capacity may be marginal or where reduced resistive losses are beneficial. The extended lower temperature operating range (-55°C vs -40°C) provides additional thermal margin for demanding environments.

Product status consideration: The main part CLF10040T-2R2N-D is in active production with 804 units in stock. The substitute CLF10060NIT-2R2N-D is designated Last Time Buy status with 1800 units available, indicating this alternative should be evaluated for long-term design continuity planning.

Packaging format differs between the two parts (Tape & Reel vs Cut Tape), which may affect procurement and assembly processes depending on production volume and equipment compatibility.

Frequently Asked Questions (FAQ)

Q: Can CLF10060NIT-2R2N-D replace CLF10040T-2R2N-D in existing designs?

A: Yes. Both parts maintain identical 2.2 µH inductance with ±30% tolerance, ferrite core shielding, surface mount configuration, and AEC-Q200 compliance. The substitute offers improved current handling and lower DC resistance, making it electrically compatible for the specified application range.

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

A: The primary differences are current rating (8.5 A vs 5 A), DC resistance (9.23 mOhm vs 12.61 mOhm), operating temperature lower limit (-55°C vs -40°C), physical dimensions (10.10mm x 10.00mm x 6.30mm vs 10.00mm x 9.70mm x 4.10mm), and packaging format (Cut Tape vs Tape & Reel).

Q: Does the physical size difference affect PCB layout?

A: Yes. The substitute part CLF10060NIT-2R2N-D has larger dimensions (0.398" L x 0.394" W x 0.248" H) compared to the main part (0.394" L x 0.382" W x 0.161" H). PCB footprint and component placement must be verified for compatibility with the substitute's increased height and lateral dimensions.

Q: Are both parts RoHS and AEC-Q200 compliant?

A: Yes. Both CLF10040T-2R2N-D and CLF10060NIT-2R2N-D are ROHS3 compliant and carry AEC-Q200 automotive qualification, meeting automotive industry reliability and environmental standards.

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

A: Last Time Buy indicates that CLF10060NIT-2R2N-D is in the final production phase with no future manufacturing planned. The available inventory of 1800 units represents the final stock. Designs selecting this substitute should establish long-term component sourcing strategy accordingly.

Q: Can the substitute handle higher current applications?

A: The CLF10060NIT-2R2N-D is rated for 8.5 A continuous current with 9 A saturation current, compared to 5 A and 7.5 A respectively for the main part. This makes the substitute suitable for applications requiring higher current capacity within the same inductance specification.
