SC2506-470 Equivalent & Substitute Parts

Part Overview

The SC2506-470 is a 47 µH unshielded inductor manufactured by Signal Transformer, rated for 560 mA continuous current with a maximum DC resistance of 880 mOhm. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The part is surface-mounted in a nonstandard package measuring 9.25mm × 7.87mm with a seated height of 1.65mm, and is fully RoHS3 compliant with unlimited moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitution of the SC2506-470 is determined by the following critical parameters:

Inductance Value & Tolerance: The substitute must maintain 47 µH ±20% inductance measured at 100 kHz to ensure circuit performance equivalence.

Current Ratings: The substitute must support a minimum continuous current rating of 560 mA and saturation current (Isat) of at least 500 mA to handle the design's power requirements without performance degradation.

DC Resistance: The substitute's maximum DC resistance must not exceed 880 mOhm to maintain acceptable power dissipation and thermal characteristics in the application.

Shielding Configuration: The substitute must be unshielded to match the electromagnetic profile of the original component.

Mounting & Package: The substitute must be surface-mount compatible. While the original uses a nonstandard package, physical dimensions and height constraints (9.25mm × 7.87mm footprint, 1.65mm max height) define the mechanical compatibility envelope.

Compliance & Environmental: The substitute must maintain RoHS3 compliance and MSL 1 rating for manufacturing process compatibility.

The UP1B-470-R from Eaton - Electronics Division meets all substitution criteria while offering improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The UP1B-470-R is a direct functional substitute for the SC2506-470 based on electrical parameter equivalence. The substitute part offers superior electrical performance with 160 mA additional current rating margin, 870 mA saturation current (370 mA above the original specification), and significantly reduced DC resistance of 474 mOhm compared to 880 mOhm maximum.

The substitute maintains full RoHS compliance and unlimited moisture sensitivity rating, ensuring manufacturing process compatibility. As an active product from Eaton - Electronics Division, the UP1B-470-R provides long-term procurement availability and supply chain stability compared to the obsolete SC2506-470.

Physical dimensions require evaluation: the UP1B-470-R footprint is smaller (8.89mm × 6.10mm versus 9.25mm × 7.87mm), but the seated height increases to 5.00mm from 1.65mm. PCB layout and vertical clearance constraints must be verified before implementation.

Frequently Asked Questions (FAQ)

Q: Can the UP1B-470-R directly replace the SC2506-470 in existing designs?

A: Electrical substitution is valid based on inductance value, tolerance, current ratings, and DC resistance specifications. Physical layout verification is required due to increased height (5.00mm versus 1.65mm) and different footprint dimensions.

Q: What are the key electrical advantages of the UP1B-470-R?

A: The substitute provides 160 mA higher continuous current rating (720 mA versus 560 mA), 370 mA higher saturation current (870 mA versus 500 mA), and 46% lower DC resistance (474 mOhm versus 880 mOhm maximum), resulting in reduced power dissipation and improved thermal performance.

Q: Are there compliance or environmental differences between these parts?

A: Both parts maintain RoHS compliance and MSL 1 (unlimited) moisture sensitivity rating. The UP1B-470-R is RoHS compliant while the original is RoHS3 compliant; both meet current regulatory requirements.

Q: What is the core material difference?

A: The SC2506-470 core material is not specified in available documentation. The UP1B-470-R uses a ferrite drum core with wirewound construction, which contributes to its improved electrical characteristics.

Q: How should PCB layout be adjusted for the UP1B-470-R?

A: The substitute's smaller footprint (8.89mm × 6.10mm) allows direct pad reuse or minor adjustment. The increased height (5.00mm) requires verification of vertical clearance to ensure no interference with adjacent components or enclosure constraints.

Q: Is the UP1B-470-R available in the same packaging format?

A: The UP1B-470-R is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Both parts use nonstandard package designations specific to their respective manufacturers.
