SC52LC-470 Equivalent & Substitute Parts

Part Overview

The SC52LC-470 is a 47 µH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring fixed inductance in compact form factors. This component is rated for 600 mA continuous current with a maximum DC resistance of 730 mOhm and operates across the temperature range of -40°C to 125°C. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts become necessary when the original SC52LC-470 experiences supply constraints, extended lead times, or when design requirements permit relaxed electrical parameters within acceptable operating margins.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC52LC-470 is determined by the following critical parameters:

• Inductance Value: Must be 47 µH with ±20% tolerance
• Current Rating: Minimum 600 mA continuous current capability
• Saturation Current: Minimum 360 mA to maintain performance under transient conditions
• DC Resistance: Maximum 730 mOhm to limit power dissipation
• Shielding Configuration: Shielded design to prevent electromagnetic interference
• Operating Temperature: Minimum range of -40°C to 125°C
• Mounting Type: Surface mount configuration for PCB integration
• Compliance: RoHS3 compliance required

The substitute parts listed below meet the core inductance specification of 47 µH. However, variations in current rating, DC resistance, shielding type, and operating temperature range create distinct substitution scenarios based on application requirements.

Engineering Selection Recommendations

VLCF4018T-470MR34-2 (TDK Corporation)

This substitute is suitable for applications where the SC52LC-470 is unavailable and current requirements do not exceed 340 mA. The VLCF4018T-470MR34-2 maintains shielded configuration, matching the electromagnetic interference characteristics of the main part. Operating temperature range extends to 105°C, providing adequate coverage for most industrial applications below the original 125°C maximum. DC resistance of 760 mOhm remains within acceptable limits for low-power circuits. The compact 4.00 x 4.00 mm footprint offers space advantages in dense PCB layouts. RoHS3 compliance and unlimited moisture sensitivity align with the original specification.

UP0.4C-470-R (Eaton - Electronics Division)

This substitute is applicable for applications where current requirements do not exceed 530 mA and electromagnetic shielding is not critical. The unshielded configuration reduces component height to 2.92 mm, beneficial for space-constrained designs. Operating temperature range of -40°C to 85°C is suitable for commercial and industrial environments but does not extend to the original 125°C maximum. DC resistance of 820 mOhm represents a 12% increase over the main part, resulting in higher power dissipation. RoHS compliance and unlimited moisture sensitivity are maintained. This option provides the highest current rating among substitutes at 530 mA.

Frequently Asked Questions (FAQ)

Q: Can the VLCF4018T-470MR34-2 replace the SC52LC-470 in all applications?

A: The VLCF4018T-470MR34-2 is suitable only for applications where continuous current does not exceed 340 mA. The SC52LC-470 is rated for 600 mA, making the TDK substitute unsuitable for higher-current designs. Verify circuit current requirements before substitution.

Q: What is the impact of the UP0.4C-470-R being unshielded compared to the shielded SC52LC-470?

A: The unshielded configuration of the UP0.4C-470-R may allow electromagnetic coupling to adjacent circuit elements. In noise-sensitive applications or high-frequency environments, this difference can affect circuit performance. Shielded designs like the SC52LC-470 and VLCF4018T-470MR34-2 provide isolation from external electromagnetic fields.

Q: Does the higher DC resistance of substitute parts affect circuit performance?

A: Both substitute parts exhibit higher DC resistance than the SC52LC-470. The UP0.4C-470-R at 820 mOhm and VLCF4018T-470MR34-2 at 760 mOhm will generate additional heat dissipation. For low-current applications, this difference is negligible. For circuits operating near maximum current ratings, thermal analysis is required.

Q: Are all three parts RoHS compliant?

A: Yes. The SC52LC-470 and VLCF4018T-470MR34-2 are ROHS3 compliant. The UP0.4C-470-R is RoHS compliant. All three parts meet environmental compliance requirements for EU and similar regulatory jurisdictions.

Q: What are the physical footprint differences between these inductors?

A: The SC52LC-470 measures 5.30 x 5.30 mm with 2.00 mm height. The VLCF4018T-470MR34-2 is the most compact at 4.00 x 4.00 mm with 1.80 mm height, suitable for dense layouts. The UP0.4C-470-R measures 6.60 x 4.45 mm with 2.92 mm height. PCB layout constraints may determine which substitute is physically compatible.

Q: Can the UP0.4C-470-R be used in applications requiring operation above 85°C?

A: No. The UP0.4C-470-R operating temperature range is -40°C to 85°C. Applications requiring sustained operation above 85°C must use the SC52LC-470 (-40°C to 125°C) or VLCF4018T-470MR34-2 (-40°C to 105°C).
