Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC414MF-560 is determined by the following critical parameters:

• Inductance Value: Must match 56 µH within the specified ±20% tolerance band
• Current Rating: Substitute must support minimum 380 mA continuous current
• DC Resistance: Lower or equal DCR values are acceptable; higher values may impact circuit performance
• Shielding: Shielded construction is required to maintain electromagnetic isolation
• Mounting Type: Surface mount configuration is mandatory for PCB compatibility
• Environmental Compliance: RoHS3 compliance and MSL rating must be maintained

The LTF3020T-560M-D from TDK Corporation meets these substitution criteria with equivalent inductance, comparable current handling, and superior thermal performance.

Parameter Comparison

Engineering Selection Recommendations

The LTF3020T-560M-D is qualified as a direct substitute based on the following factors:

• Inductance Match: Both parts specify 56 µH with ±20% tolerance, ensuring circuit-level compatibility
• Current Handling: The substitute's 370 mA rating is within 97% of the original 380 mA specification, acceptable for most applications
• Resistance Advantage: The LTF3020T-560M-D exhibits 18% lower DC resistance (1.21Ohm vs. 1.48Ohm), reducing power dissipation
• Thermal Performance: Extended operating range to 150°C provides additional design margin
• Compliance Status: Both components maintain ROHS3 compliance and MSL-1 rating
• Product Availability: The substitute is in active production status, ensuring long-term procurement viability

Frequently Asked Questions (FAQ)

Q: Can the LTF3020T-560M-D replace the SC414MF-560 in existing designs?

A: Yes. Both inductors share identical inductance values, equivalent tolerance specifications, and compatible current ratings. The substitute's lower DC resistance and extended temperature range provide performance benefits without circuit modification.

Q: What is the impact of the 10 mA current rating difference?

A: The LTF3020T-560M-D operates at 370 mA versus the original 380 mA. This 2.6% reduction is negligible for most applications. Verify that your circuit's maximum current demand does not exceed 370 mA.

Q: Are the physical dimensions compatible?

A: Both parts use nonstandard surface mount packages. The LTF3020T-560M-D measures 4.50mm × 3.00mm × 2.00mm (max height) compared to the SC414MF-560 at 4.30mm × 4.30mm × 1.50mm (max height). PCB footprint verification is required before implementation.

Q: Does the lower DC resistance affect circuit behavior?

A: Lower DC resistance reduces I²R losses and heat generation. This is a beneficial characteristic that improves efficiency. No circuit redesign is necessary.

Q: Are both parts RoHS compliant?

A: Yes. Both the SC414MF-560 and LTF3020T-560M-D are ROHS3 compliant with MSL-1 moisture sensitivity ratings.

Q: What is the difference in inductance test frequency?

A: The SC414MF-560 is tested at 100 kHz, while the LTF3020T-560M-D is tested at 1 MHz. Both measurements confirm the 56 µH specification within the stated tolerance band.
