SC63LCB-470 Equivalent & Substitute Parts

Part Overview

The SC63LCB-470 is a 47 µH shielded inductor manufactured by Signal Transformer, rated for 1.14 A continuous current with a maximum DC resistance of 235mOhm. This surface mount component operates across the industrial temperature range of -40°C to 125°C and is ROHS3 compliant. The part is currently active in production with 683 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, design flexibility, or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC63LCB-470 is determined by the following criteria:

• Inductance value must be 47 µH with ±20% tolerance
• Current rating must meet or exceed 1.14 A continuous operation
• DC resistance must not exceed 235mOhm to maintain equivalent power dissipation characteristics
• Shielding type must be shielded or semi-shielded to control electromagnetic interference
• Operating temperature range must encompass -40°C to 125°C
• Mounting type must be surface mount
• RoHS3 compliance is required

All three substitute parts meet these core electrical and mechanical requirements while maintaining compatibility with the original design specifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the SC63LCB-470.

DR74-470-R offers the lowest DC resistance at 216mOhm and the highest current rating at 1.15 A, providing the best thermal performance margin. This part is suitable for applications where power dissipation minimization is critical.

DR73-470-R provides a shielded drum core construction with 241mOhm DCR and 1.08 A rating. While the current rating is slightly below the main part, it remains within acceptable substitution parameters for most applications.

SRN6045-470M from Bourns offers the highest inventory availability at 35,889 units and includes additional Q factor specification (13 @ 2.52MHz) and self-resonant frequency data (7MHz). The semi-shielded configuration and 257mOhm DCR represent acceptable trade-offs for applications where EMI control is less stringent. This part provides the best supply security.

Frequently Asked Questions (FAQ)

Q: Can DR73-470-R be used as a direct replacement for SC63LCB-470?

A: DR73-470-R meets the core substitution criteria with matching 47 µH inductance, ±20% tolerance, shielded construction, and operating temperature range. The 1.08 A current rating is slightly lower than the 1.14 A main part specification, and DCR is 241mOhm versus 235mOhm maximum. Substitution is valid for applications where the actual operating current does not exceed 1.08 A.

Q: What is the difference between shielded and semi-shielded inductors?

A: Shielded inductors (SC63LCB-470, DR73-470-R, DR74-470-R) provide complete electromagnetic containment. Semi-shielded inductors (SRN6045-470M) offer partial shielding. Semi-shielded designs are suitable for applications with lower EMI sensitivity requirements and provide cost and size advantages.

Q: Which substitute offers the best thermal performance?

A: DR74-470-R provides the lowest DC resistance at 216mOhm and highest current rating at 1.15 A, resulting in the lowest power dissipation and best thermal margin for continuous operation.

Q: Are all substitutes available in tape and reel packaging?

A: Yes. All three substitute parts are supplied in Tape & Reel (TR) packaging. The main part SC63LCB-470 uses nonstandard packaging. Tape and reel packaging is standard for automated assembly processes.

Q: Do all parts meet the same compliance standards?

A: All four parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Regulatory compliance is equivalent across all options.
