SC62CB-470 Equivalent & Substitute Parts

Part Overview

The SC62CB-470 is a 47 µH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring moderate current handling and low DC resistance. This component is classified as Active product status with full RoHS3 compliance. Substitute parts become necessary when the original component faces supply constraints, extended lead times, or when design requirements permit alternative core construction or shielding configurations while maintaining electrical performance within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

The B82471A1473M000 (EPCOS - TDK Electronics) qualifies as an equivalent substitute based on the following critical parameters:

Inductance value matches at 47 µH with identical ±20% tolerance. Current rating of 720 mA remains within acceptable operational range for the SC62CB-470 application envelope. DC resistance of 370 mOhm is lower than the 390 mOhm maximum specification, providing improved efficiency. Saturation current of 850 mA exceeds the original 480 mA, offering enhanced headroom. Surface mount configuration and nonstandard package dimensions remain compatible. Both components operate across overlapping temperature ranges with the substitute offering extended lower temperature capability (-55°C vs -40°C). RoHS3 compliance and MSL 1 rating are maintained.

The primary distinction is shielding configuration: the substitute employs an unshielded drum core wirewound design versus the original shielded construction. This substitution is valid only when electromagnetic interference considerations do not require shielding in the target application.

Parameter Comparison

Engineering Selection Recommendations

Selection between SC62CB-470 and B82471A1473M000 depends on application-specific requirements:

Choose SC62CB-470 when electromagnetic shielding is mandatory to prevent coupling with adjacent circuit elements or to meet conducted emissions specifications. The shielded construction provides isolation in densely populated PCB layouts.

Choose B82471A1473M000 when shielding is not required and supply availability or cost considerations favor the EPCOS alternative. The lower DC resistance (370 mOhm vs 390 mOhm) reduces power dissipation. The higher saturation current (850 mA vs 480 mA) provides additional design margin. Both components maintain full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent environmental and regulatory compliance.

Physical dimensions differ slightly; verify PCB footprint clearance, particularly the increased height of 4.90mm for the substitute versus 2.50mm for the original.

Frequently Asked Questions (FAQ)

Q: Can B82471A1473M000 replace SC62CB-470 in all applications?

A: Electrical substitution is valid when shielding is not a circuit requirement. The unshielded drum core construction of B82471A1473M000 may introduce coupling in sensitive analog or RF circuits. Verify that electromagnetic isolation is not specified in your design documentation.

Q: What is the impact of the lower DC resistance in the substitute part?

A: Lower DC resistance (370 mOhm vs 390 mOhm) reduces resistive losses and heat generation during operation. This improves efficiency and is generally beneficial unless your circuit design specifically accounts for the original resistance value in current-limiting applications.

Q: Are the physical dimensions compatible?

A: Both parts use nonstandard packages with similar footprints (6.30mm vs 6.10mm length, 6.20mm vs 5.60mm width). However, the substitute is significantly taller (4.90mm vs 2.50mm). Verify clearance above the component on your PCB layout before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SC62CB-470 and B82471A1473M000 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What is the difference between shielded and unshielded inductors?

A: Shielded inductors (SC62CB-470) contain a magnetic shield that confines the magnetic field, reducing coupling to nearby components. Unshielded inductors (B82471A1473M000) allow the magnetic field to extend into surrounding space, which may cause interference in sensitive circuits but offers lower cost and smaller height in some designs.
