Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC414MF-5R6 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Inductance value must be 5.6 µH
• Current rating must meet or exceed 1.3 A
• DC resistance must not exceed 188 mOhm to maintain circuit performance
• Saturation current must support the application's peak current demands
• Shielding type must remain shielded to preserve EMI characteristics

Mechanical and Environmental Criteria:

• Surface mount package configuration required
• Operating temperature range must encompass -40°C to 125°C minimum
• RoHS3 compliance mandatory for regulatory alignment
• Nonstandard package dimensions must accommodate existing PCB layouts

The LTF3020T-5R6N-D from TDK Corporation meets these substitution requirements while offering active product status and extended temperature capability.

Engineering Selection Recommendations

The LTF3020T-5R6N-D is the qualified substitute for the obsolete SC414MF-5R6. Selection is based on the following engineering factors:

Product Status: The SC414MF-5R6 is obsolete, necessitating transition to an active component. The LTF3020T-5R6N-D maintains active product status with established supply chain availability.

Compliance and Certifications: Both components are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment. The LTF3020T-5R6N-D carries AEC-Q200 qualification, providing automotive-grade reliability assurance.

Electrical Performance: The substitute maintains identical inductance at 5.6 µH with superior DC resistance (170 mOhm vs. 188 mOhm). The current rating differential (1.07 A vs. 1.3 A) and saturation current reduction (790 mA vs. 1.1 A) require circuit-level evaluation to confirm application compatibility.

Temperature Performance: The LTF3020T-5R6N-D extends the upper operating temperature to 150°C, providing additional thermal margin beyond the original specification of 125°C.

Frequently Asked Questions (FAQ)

Q: Can the LTF3020T-5R6N-D directly replace the SC414MF-5R6 in all applications?

A: Direct substitution requires verification of current rating compatibility. The LTF3020T-5R6N-D is rated for 1.07 A continuous current compared to the original 1.3 A rating. Applications operating below 1.07 A are compatible. Applications requiring the full 1.3 A rating require circuit redesign or alternative component selection.

Q: What is the impact of the inductance tolerance difference?

A: The SC414MF-5R6 specifies ±20% tolerance while the LTF3020T-5R6N-D specifies ±30% tolerance. Circuit designs with tight inductance requirements must account for the wider tolerance band of the substitute part.

Q: Are the package dimensions compatible?

A: Both components use nonstandard surface mount packages. The SC414MF-5R6 measures 4.30mm × 4.30mm × 1.50mm (height), while the LTF3020T-5R6N-D measures 4.50mm × 3.00mm × 2.00mm (height). PCB layout verification is required to confirm mechanical fit within existing footprints.

Q: What certifications does the substitute part carry?

A: The LTF3020T-5R6N-D carries AEC-Q200 automotive qualification in addition to ROHS3 compliance and REACH compliance status, matching the regulatory requirements of the original part.

Q: How does the DC resistance comparison affect circuit performance?

A: The LTF3020T-5R6N-D exhibits lower DC resistance (170 mOhm vs. 188 mOhm), resulting in reduced resistive losses and improved efficiency in the application circuit.
