SC52LC-150 Equivalent & Substitute Parts

Part Overview

The SC52LC-150 is a 15 µH shielded inductor manufactured by Signal Transformer, designed for surface mount applications in the nonstandard package category. This component operates across the temperature range of -40°C to 125°C and is classified as Active product status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility exist within the allowed parameter tolerances for this inductor category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC52LC-150 are qualified based on the following criteria:

• Inductance value: 15 µH (matching specification)
• Inductance tolerance: ±20% (matching specification)
• Shielding type: Shielded (matching specification)
• Mounting type: Surface Mount (matching specification)
• Test frequency: 100 kHz (matching specification)
• RoHS compliance: ROHS3 Compliant (matching specification)
• Moisture sensitivity: MSL 1 (matching specification)

The substitute parts VLCF4018T-150MR59-2 and VLCF5020T-150MR71 meet these core electrical and compliance requirements. Variations in current rating, saturation current, and DC resistance are within acceptable ranges for inductor substitution in this category. Operating temperature range differences and package dimensions are noted for application-specific verification.

Parameter Comparison

Engineering Selection Recommendations

All three inductors—SC52LC-150, VLCF4018T-150MR59-2, and VLCF5020T-150MR71—maintain Active product status and ROHS3 compliance. Selection between these parts depends on application current requirements and operating temperature constraints.

The SC52LC-150 supports the highest current rating at 1.16 A with an operating temperature range extending to 125°C. The VLCF5020T-150MR71 provides the next highest current capacity at 710 mA with a maximum operating temperature of 105°C. The VLCF4018T-150MR59-2 is rated for 590 mA maximum current and also operates to 105°C maximum.

All parts share identical inductance values, tolerance specifications, shielding characteristics, and moisture sensitivity ratings. DC resistance values remain within acceptable engineering margins across all three options.

Frequently Asked Questions (FAQ)

Q: Can VLCF4018T-150MR59-2 or VLCF5020T-150MR71 directly replace SC52LC-150 in all applications?

A: Direct substitution is valid when the application current requirement does not exceed the substitute part's current rating. VLCF4018T-150MR59-2 is limited to 590 mA, and VLCF5020T-150MR71 is limited to 710 mA. Applications requiring currents above these thresholds must use SC52LC-150 or equivalent higher-current inductors.

Q: What is the impact of the 20°C operating temperature difference?

A: SC52LC-150 operates to 125°C maximum, while both TDK substitutes operate to 105°C maximum. Applications requiring operation above 105°C must use SC52LC-150 or equivalent high-temperature rated inductors.

Q: Are the DC resistance differences significant?

A: DC resistance values are 230 mOhm (SC52LC-150), 268 mOhm (VLCF4018T-150MR59-2), and 256 mOhm (VLCF5020T-150MR71). These differences fall within standard inductor manufacturing tolerances and do not constitute a substitution barrier for most applications.

Q: Do all parts meet the same compliance requirements?

A: Yes. All three inductors are ROHS3 compliant, REACH unaffected, classified as MSL 1 (Unlimited), and carry EAR99 ECCN designation.

Q: What are the package dimension differences?

A: SC52LC-150 measures 5.30mm × 5.30mm × 2.00mm (height). VLCF4018T-150MR59-2 measures 4.00mm × 4.00mm × 1.80mm. VLCF5020T-150MR71 measures 5.00mm × 5.00mm × 2.00mm. Physical space constraints in the application circuit must be evaluated for each substitute option.
