SC52LC-2R2 Equivalent & Substitute Parts

Part Overview

The SC52LC-2R2 is a 2.2 µH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring 3 A current rating and 59mOhm maximum DC resistance. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory constraints require component alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC52LC-2R2 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Inductance value must match: 2.2 µH
• Inductance tolerance must be ±30% or tighter
• Current rating must be equal to or greater than 3 A
• DC resistance must not exceed 59mOhm maximum
• Shielding type must be Shielded

Mechanical Compatibility Requirements:

• Mounting type must be Surface Mount
• Package footprint must accommodate 5.30mm x 5.30mm x 2.00mm maximum height dimensions
• Operating temperature range must cover -40°C ~ 125°C or be compatible with application requirements

Compliance Requirements:

• RoHS3 compliance required
• Moisture sensitivity level MSL 1 (Unlimited) required

The VLCF5020T-2R2N2R6-1 from TDK Corporation qualifies as a substitute based on matching inductance value, tolerance, shielding type, surface mount configuration, and compliance certifications. Electrical parameter variations are documented in the comparison table below.

Engineering Selection Recommendations

SC52LC-2R2 Primary Selection: Use the SC52LC-2R2 when the full 3 A current rating and 125°C maximum operating temperature are required. This part maintains the lowest DC resistance specification at 59mOhm maximum and provides the highest saturation current margin at 1.63 A.

VLCF5020T-2R2N2R6-1 Substitute Selection: The VLCF5020T-2R2N2R6-1 is suitable as a substitute when application current requirements do not exceed 2.62 A and operating temperature does not exceed 105°C. This part features a smaller footprint (5.00mm x 5.00mm versus 5.30mm x 5.30mm) and higher saturation current at 2.62 A. The increased DC resistance of 71mOhm maximum versus 59mOhm maximum must be evaluated for thermal and efficiency impact in the target application.

Both parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the VLCF5020T-2R2N2R6-1 replace the SC52LC-2R2 in all applications?

A: The VLCF5020T-2R2N2R6-1 is suitable only when application current requirements do not exceed 2.62 A and maximum operating temperature does not exceed 105°C. The SC52LC-2R2 supports higher current (3 A) and higher temperature operation (125°C). Verify application requirements before substitution.

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

A: The VLCF5020T-2R2N2R6-1 has 71mOhm maximum DC resistance compared to 59mOhm maximum in the SC52LC-2R2. This 12mOhm increase results in higher resistive losses and heat generation at rated current. Calculate power dissipation impact using I²R losses for your specific application current profile.

Q: Are the physical dimensions compatible for PCB layout?

A: The VLCF5020T-2R2N2R6-1 has a smaller footprint (5.00mm x 5.00mm) compared to the SC52LC-2R2 (5.30mm x 5.30mm). Both maintain identical maximum height of 2.00mm. The smaller footprint may provide layout advantages, but verify that your PCB design accommodates the different pad spacing.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the SC52LC-2R2 and VLCF5020T-2R2N2R6-1 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified as Active product status.

Q: What is the inductance tolerance specification for both parts?

A: Both parts specify ±30% inductance tolerance at 100 kHz test frequency. This tolerance must be considered in circuit design calculations for both the primary and substitute part.
