Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CLF6045T-2R2N-H are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Inductance Value: Must be 2.2 µH with ±30% tolerance
• Current Rating: Minimum 4 A continuous current capability
• DC Resistance: Must not exceed the original 15 mOhm specification for thermal and efficiency considerations
• Core Material & Shielding: Ferrite drum core with shielding to maintain electromagnetic isolation
• Package Footprint: Surface mount nonstandard package with compatible dimensions
• Mounting Compatibility: Surface mount technology (SMT) for direct PCB integration

The CLF6045NIT-2R2N-D (TDK Corporation) and ASPI-6045S-2R2N-T (Abracon LLC) meet these criteria with enhanced or equivalent electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

CLF6045NIT-2R2N-D (TDK Corporation) is the manufacturer-recommended direct substitute. This part maintains TDK product continuity with active product status and AEC-Q200 automotive qualification. The CLF6045NIT-2R2N-D provides improved saturation current (4.2 A vs. 3.9 A) and extended operating temperature range (-55°C to 150°C). The DC resistance specification increases to 20 mOhm maximum, which represents a 33% increase from the original 15 mOhm. This trade-off is acceptable for applications where thermal dissipation is not the limiting factor.

ASPI-6045S-2R2N-T (Abracon LLC) offers superior electrical performance with the lowest DC resistance (14 mOhm) and highest saturation current (6.75 A). This part is suitable for applications requiring enhanced current handling and reduced power loss. The package dimensions are slightly smaller (6.00mm x 6.00mm footprint), which may require PCB layout verification for mechanical clearance.

Both substitute parts are ROHS3 compliant and available in tape and reel packaging. Selection between CLF6045NIT-2R2N-D and ASPI-6045S-2R2N-T depends on thermal budget requirements, temperature operating range, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can CLF6045NIT-2R2N-D directly replace CLF6045T-2R2N-H without PCB modifications?

A: Yes, for most applications. Both parts share identical inductance (2.2 µH), tolerance (±30%), and similar package dimensions. The CLF6045NIT-2R2N-D footprint (6.30mm x 6.00mm x 4.80mm) is marginally larger than the original (6.20mm x 5.90mm x 4.50mm). Verify PCB layout clearances before implementation. The increased DC resistance (20 mOhm vs. 15 mOhm) will generate additional heat; confirm thermal design margins in your application.

Q: What is the impact of increased DC resistance in CLF6045NIT-2R2N-D?

A: DC resistance directly affects power dissipation and thermal performance. At 4 A, the CLF6045NIT-2R2N-D dissipates 320 mW (I²R = 16 × 0.020) compared to 240 mW for the original part (16 × 0.015). This 33% increase in dissipation requires verification that thermal design margins remain adequate for your application's ambient temperature and thermal management strategy.

Q: Is ASPI-6045S-2R2N-T suitable for high-current applications?

A: Yes. The ASPI-6045S-2R2N-T provides the highest saturation current (6.75 A) and lowest DC resistance (14 mOhm) among the three parts. At 4 A operation, it dissipates 224 mW, offering improved thermal performance. The smaller footprint (6.00mm x 6.00mm) may require PCB layout adjustment; verify mechanical clearance and trace routing compatibility.

Q: Are all substitute parts automotive-qualified?

A: CLF6045NIT-2R2N-D carries AEC-Q200 qualification, suitable for automotive applications. ASPI-6045S-2R2N-T does not list automotive qualification in the provided specifications. Verify AEC-Q200 or equivalent automotive compliance requirements for your application before selection.

Q: What is the frequency test condition for inductance specification?

A: All three parts specify inductance at 100 kHz test frequency. This is the standard measurement condition for SMD inductors and ensures consistent comparison across parts.
