SC52LC-100 Equivalent & Substitute Parts

Part Overview

The SC52LC-100 is a 10 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 1.44 A continuous current with a maximum DC resistance of 150mOhm. The component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific requirements within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC52LC-100 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value must match at 10 µH within the ±20% tolerance band
• Current rating must meet or exceed 1.44 A to support the same load conditions
• DC resistance must not exceed 150mOhm to maintain thermal and efficiency characteristics
• Inductance test frequency must be 100 kHz, consistent with measurement standards

Mechanical Compatibility Criteria:

• Surface mount mounting type required
• Nonstandard package classification
• Operating temperature range must encompass -40°C minimum and 125°C maximum

Compliance Requirements:

• ROHS3 compliance mandatory
• Moisture sensitivity level 1 (Unlimited) acceptable

The substitute part P0770.103NLT from Pulse Electronics meets the inductance, tolerance, mounting type, temperature range, and compliance requirements. However, the current rating of 1.1 A is below the 1.44 A specification, and the DC resistance of 160mOhm exceeds the 150mOhm maximum. Additionally, the substitute is unshielded versus the shielded design of the main part. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both components maintain Active product status and ROHS3 compliance. The SC52LC-100 and P0770.103NLT share identical inductance values, tolerance specifications, and moisture sensitivity ratings. Selection between these parts must account for the following documented differences:

The P0770.103NLT exhibits a current rating 0.34 A lower than the SC52LC-100 specification and a DC resistance 10mOhm higher. The substitute part is unshielded, whereas the main part is shielded. Physical dimensions differ, with the P0770.103NLT measuring larger in length and height. These parameter variations require evaluation within the context of the specific application's current handling requirements, electromagnetic interference considerations, and available board space.

Frequently Asked Questions (FAQ)

Q: Can P0770.103NLT be used as a direct replacement for SC52LC-100?

A: Direct replacement is not supported without application review. The P0770.103NLT has a lower current rating (1.1 A vs. 1.44 A), higher DC resistance (160mOhm vs. 150mOhm), and is unshielded versus shielded. These differences may impact circuit performance depending on load conditions and EMI sensitivity.

Q: What is the significance of the shielding difference?

A: The SC52LC-100 is shielded, which reduces electromagnetic radiation and susceptibility to external fields. The P0770.103NLT is unshielded. Applications requiring EMI suppression or operating in electromagnetically noisy environments may require the shielded design.

Q: Are the physical dimensions compatible with the same PCB layout?

A: No. The SC52LC-100 measures 5.30mm x 5.30mm with a maximum height of 2.00mm. The P0770.103NLT measures 6.60mm x 4.45mm with a maximum height of 2.92mm. PCB footprint and clearance verification is required before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SC52LC-100 and P0770.103NLT are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited). Both are rated for -40°C to 125°C minimum operating range, with P0770.103NLT extending to 130°C maximum.

Q: What is the impact of the current rating difference?

A: The SC52LC-100 supports continuous current up to 1.44 A. The P0770.103NLT is rated for 1.1 A. Applications requiring the full 1.44 A rating cannot use the substitute without risk of thermal stress or saturation. The saturation current (Isat) of P0770.103NLT is 1.1 A, matching its continuous rating.
