39U562C Equivalent & Substitute Parts

Part Overview

The 39U562C is a 5.6 µH unshielded wirewound inductor manufactured by Murata Power Solutions Inc., rated for 6.6 A continuous current with a maximum DC resistance of 14.6 mOhm. This component is classified as Active product status and is RoHS3 compliant. Surface mount inductors of this specification are essential in power conversion circuits, filtering applications, and energy storage stages where precise inductance values and current handling capabilities are critical design parameters. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for this product category.

Substitute Part Grouping Explanation

Substitute parts for the 39U562C are qualified based on the following electrical and mechanical parameters:

  • Inductance Value: Exact match at 5.6 µH with ±20% tolerance specification
  • Current Rating: Equal to or greater than 6.6 A continuous rating
  • DC Resistance: Equal to or less than 14.6 mOhm maximum
  • Operating Temperature Range: Minimum coverage of -40°C to 125°C
  • Mounting Type: Surface mount configuration
  • Package Compatibility: Nonstandard package with compatible physical dimensions
  • Regulatory Compliance: RoHS3 compliant status maintained

The CEP125NP-5R6MC-H qualifies as a substitute based on these criteria. While it features shielded construction (versus unshielded in the original), it maintains the required inductance value, exceeds the current rating requirement, reduces DC resistance, and maintains full temperature range and compliance specifications.

Engineering Selection Recommendations

Both the 39U562C and CEP125NP-5R6MC-H maintain Active product status and full RoHS3 compliance. The CEP125NP-5R6MC-H provides improved DC resistance performance (11.4 mOhm versus 14.6 mOhm) and higher continuous current rating (8.2 A versus 6.6 A), resulting in lower thermal dissipation and enhanced current handling capacity. The primary design difference is the shielded drum core construction of the substitute versus the unshielded wirewound design of the original part. Both components are rated for identical operating temperature ranges and moisture sensitivity levels. Selection between these parts should be based on circuit-specific requirements regarding electromagnetic shielding, physical space constraints, and thermal management priorities.

Frequently Asked Questions (FAQ)

Q: Can the CEP125NP-5R6MC-H directly replace the 39U562C in all applications?

A: The CEP125NP-5R6MC-H meets or exceeds all specified electrical parameters for the 39U562C. The primary design difference is shielded versus unshielded construction. Applications requiring unshielded operation or with specific EMI considerations should evaluate this difference. Physical dimensions are comparable but not identical (12.90mm × 12.90mm versus 12.50mm × 12.50mm).

Q: What is the significance of the lower saturation current in the substitute part?

A: The CEP125NP-5R6MC-H has a saturation current of 8.8 A compared to 9.5 A in the 39U562C. Since the continuous current rating of the substitute (8.2 A) remains above the original specification (6.6 A), this does not impact normal operating conditions. Applications operating near saturation limits should verify this parameter against circuit requirements.

Q: Does the shielded construction of the substitute affect circuit performance?

A: Shielded construction reduces electromagnetic radiation and susceptibility to external fields. In applications where the original unshielded design was selected for specific EMI characteristics, the shielded substitute may alter circuit behavior. Circuit validation is necessary for noise-sensitive applications.

Q: Are both parts available in the same packaging format?

A: Both parts are supplied in Tape & Reel (TR) packaging and are classified as Nonstandard package types. Physical dimensions differ slightly: 39U562C measures 12.90mm × 12.90mm × 5.80mm (max height), while CEP125NP-5R6MC-H measures 12.50mm × 12.50mm × 5.60mm (max height). PCB layout verification is recommended before implementation.

Q: What compliance certifications apply to both parts?

A: Both the 39U562C and CEP125NP-5R6MC-H are RoHS3 compliant, REACH unaffected, classified under ECCN EAR99, and assigned HTSUS code 8504.50.4000. Both maintain Moisture Sensitivity Level 1 (Unlimited).
