PD54R-563K Equivalent & Substitute Parts

Part Overview

The PD54R-563K is a 56 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., designed for surface mount applications. This component operates at 680 mA rated current with a maximum DC resistance of 420 mOhm and functions across the temperature range of -55°C to 125°C. The part maintains Active product status and is RoHS3 compliant. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements permit alternative qualified sources.

Engineering Selection Recommendations

Primary Part: PD54R-563K The PD54R-563K remains the specified component for applications where API Delevan sourcing is required or preferred. This part is Active status, RoHS3 compliant, and maintains full compliance with REACH and EAR99 export classifications.

Substitute Part: SDR0604-560KL The SDR0604-560KL from Bourns Inc. is qualified as a direct substitute based on electrical parameter equivalence and compliance certification. This part exceeds saturation current requirements (900 mA vs. 680 mA specification) and maintains identical DC resistance and inductance values. The operating temperature range of -40°C to 125°C covers the majority of industrial applications; however, designs requiring operation below -40°C must retain the PD54R-563K.

Minor dimensional variations exist between the two parts. The SDR0604-560KL measures 0.228" L x 0.228" W with a maximum seated height of 0.189", compared to the PD54R-563K at 0.224" L x 0.201" W with 0.177" maximum height. PCB layout and component placement clearances must accommodate these dimensional differences.

Both parts maintain Active product status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-560KL replace the PD54R-563K in all applications?

A: The SDR0604-560KL is electrically equivalent for applications operating within the -40°C to 125°C temperature range. Applications requiring operation below -40°C must use the PD54R-563K, which is rated to -55°C. PCB layout must accommodate the SDR0604-560KL's slightly larger footprint (0.228" x 0.228" vs. 0.224" x 0.201") and greater seated height (0.189" vs. 0.177").

Q: Are both parts RoHS3 compliant?

A: Yes. Both the PD54R-563K and SDR0604-560KL are RoHS3 compliant with MSL rating 1 (Unlimited) and REACH unaffected status.

Q: What is the difference in saturation current between these parts?

A: The PD54R-563K has a saturation current (Isat) of 680 mA, matching its rated current. The SDR0604-560KL has a saturation current of 900 mA, providing additional margin above the 680 mA rated current specification. Both parts meet the minimum saturation requirement.

Q: Do these parts have identical DC resistance?

A: Yes. Both parts specify a maximum DC resistance of 420 mOhm at the rated current of 680 mA.

Q: Are there any frequency-dependent differences?

A: The SDR0604-560KL provides additional frequency characterization data: Q factor of 22 at 2.52 MHz and self-resonant frequency of 11 MHz. The PD54R-563K does not specify these parameters. Both parts are tested for inductance at 1 kHz per specification.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
