Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLF6045T-150M-D is determined by the following critical parameters:

Inductance value must remain 15 µH within the ±20% tolerance band. Core material must be ferrite with shielding maintained. Mounting type must be surface mount with nonstandard package classification. Operating temperature range must encompass or exceed the application's thermal requirements. AEC-Q200 automotive qualification must be present. RoHS3 compliance must be maintained.

The CLF6045NIT-150M-D qualifies as a substitute based on matching inductance (15 µH), core type (ferrite, shielded), mounting method (surface mount), package classification (nonstandard), compliance certifications (AEC-Q200, RoHS3), and physical footprint compatibility. Variations in current rating, DC resistance, and saturation current are acceptable within the constraints of the application's electrical design.

Parameter Comparison

Engineering Selection Recommendations

Both CLF6045T-150M-D and CLF6045NIT-150M-D are active production components from TDK Corporation with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on application-specific current and temperature requirements.

The CLF6045T-150M-D provides higher current capacity (2.0 A rated, 1.5 A saturation) with lower DC resistance (66 mOhm max) and is suitable for applications requiring maximum current handling within the -40 to 150°C operating window.

The CLF6045NIT-150M-D offers extended low-temperature operation (-55°C minimum) with slightly reduced current capacity (1.7 A rated and saturation) and marginally higher DC resistance (72 mOhm max). This variant is appropriate for applications prioritizing cold-temperature performance or where the reduced current rating is acceptable.

Both parts maintain identical inductance (15 µH), core material (ferrite), shielding, and mounting characteristics. Physical dimensions differ slightly (6.30 × 6.00 mm vs. 6.20 × 5.90 mm), requiring verification of PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can CLF6045NIT-150M-D replace CLF6045T-150M-D in all applications?

A: Substitution is valid only when the application's maximum continuous current does not exceed 1.7 A and the minimum operating temperature requirement does not fall below -55°C. The inductance value, tolerance, core material, and shielding are identical, ensuring equivalent magnetic performance. DC resistance difference (72 mOhm vs. 66 mOhm) introduces minimal additional losses in most circuit topologies.

Q: What are the physical footprint differences?

A: The CLF6045NIT-150M-D is slightly larger (6.30 × 6.00 mm) compared to the CLF6045T-150M-D (6.20 × 5.90 mm). Height is identical at 4.80 mm. PCB layout must accommodate the larger footprint; the substitute part may not fit in designs with tight spatial constraints.

Q: Are both parts qualified for automotive applications?

A: Yes. Both CLF6045T-150M-D and CLF6045NIT-150M-D carry AEC-Q200 automotive qualification and are suitable for automotive-grade circuit designs.

Q: How do the DC resistance values affect circuit performance?

A: The 6 mOhm difference (66 mOhm vs. 72 mOhm) represents approximately 9% higher resistance in the substitute part. In applications where inductor losses are critical, thermal analysis should confirm acceptable power dissipation at the application's operating current.

Q: Can the CLF6045T-150M-D replace CLF6045NIT-150M-D?

A: Yes, the CLF6045T-150M-D is a direct replacement when the application does not require the extended -55°C low-temperature capability of the NIT variant. All other electrical and mechanical parameters are compatible.
