SC2506-220 Equivalent & Substitute Parts

Part Overview

The SC2506-220 is a 22 µH unshielded inductor manufactured by Signal Transformer, rated for 780 mA continuous current with a maximum DC resistance of 420mOhm. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The part is mounted as a surface mount device in a nonstandard package measuring 9.25mm × 7.87mm with a seated height of 1.65mm.

Key Parameters

Substitute Part Grouping Explanation

The UP1B-220-R from Eaton - Electronics Division qualifies as a substitute for the SC2506-220 based on the following critical parameters:

• Inductance Value: Both parts are rated at 22 µH with ±20% tolerance, meeting the core functional requirement
• Inductance Test Frequency: Both measured at 100 kHz
• Shielding Configuration: Both are unshielded designs
• Mounting Technology: Both are surface mount components
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The UP1B-220-R provides improved electrical performance with a higher current rating (1 A vs. 780 mA) and lower DC resistance (254.1 mOhm vs. 420 mOhm), while maintaining the same inductance specification and tolerance band.

Parameter Comparison

Engineering Selection Recommendations

The UP1B-220-R is suitable as a substitute for the SC2506-220 from a regulatory and compliance standpoint. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental standards. The substitute part carries active product status from Eaton, providing long-term availability and supply chain stability compared to the obsolete SC2506-220.

Physical dimensions require evaluation during board layout integration. The UP1B-220-R is slightly smaller in footprint (8.89mm × 6.10mm vs. 9.25mm × 7.87mm) but significantly taller (5.00mm vs. 1.65mm seated height). This height difference may impact PCB assembly clearance and component placement constraints.

The UP1B-220-R delivers superior electrical performance with 28% higher current rating and 39% lower DC resistance, making it electrically compatible for applications where the SC2506-220 was specified at or below its rated limits.

Frequently Asked Questions (FAQ)

Q: Can the UP1B-220-R directly replace the SC2506-220 in existing designs?

A: Electrical substitution is valid based on matching inductance value, tolerance, and test frequency. Physical substitution requires verification of PCB layout constraints, particularly the increased seated height of 5.00mm versus 1.65mm.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete vs. active), current rating (780 mA vs. 1 A), DC resistance (420 mOhm vs. 254.1 mOhm), and physical height. Inductance value and tolerance remain identical at 22 µH ±20%.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the SC2506-220 and UP1B-220-R are ROHS3 compliant and REACH unaffected, meeting current environmental standards for electronic components.

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

A: Lower DC resistance (254.1 mOhm vs. 420 mOhm) reduces resistive losses and heat generation in the inductor, improving efficiency in power conversion and filtering applications.

Q: Does the substitute part require different handling or storage?

A: Both parts share identical moisture sensitivity levels (MSL 1 - Unlimited), requiring no change to handling, storage, or packaging procedures.

Q: How do the package dimensions affect PCB design?

A: The UP1B-220-R footprint is smaller in length and width but substantially taller. PCB designers must verify clearance above the component to accommodate the 5.00mm seated height, particularly in space-constrained applications.
