Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PD54R-823K is determined by the following critical parameters:

• Inductance value: 82 µH ±10%
• Current rating: minimum 580 mA
• DC resistance: maximum 600 mOhm
• Core type: Ferrite, unshielded drum core
• Mounting type: Surface Mount
• RoHS3 compliance
• Operating temperature range: minimum -40°C ~ 125°C

The SDR0604-820KL from Bourns Inc. meets all substitution criteria. Both components share identical inductance, tolerance, current rating, DC resistance specification, core material, and RoHS compliance status. Dimensional variations and packaging format differences do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the PD54R-823K and SDR0604-820KL are active production components with ROHS3 compliance and identical electrical specifications for inductance, tolerance, current rating, and DC resistance. Selection between these parts should be based on:

Packaging format availability: The PD54R-823K is supplied in Tape & Reel format, while the SDR0604-820KL is available in Cut Tape and Digi-Reel formats.

Operating temperature requirements: The PD54R-823K supports -55°C ~ 125°C operation, providing extended low-temperature performance compared to the SDR0604-820KL at -40°C ~ 125°C.

Saturation current margin: The SDR0604-820KL provides higher saturation current (750 mA) compared to the PD54R-823K (580 mA), offering additional headroom in applications approaching saturation limits.

Physical dimensions: Minor dimensional differences exist; verify PCB layout compatibility before substitution.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-820KL directly replace the PD54R-823K in all applications?

A: Yes, for applications operating within -40°C ~ 125°C. If operation below -40°C is required, the PD54R-823K must be used due to its extended temperature range.

Q: Are there differences in electrical performance between these inductors?

A: Both components have identical inductance (82 µH), tolerance (±10%), current rating (580 mA), and DC resistance (600 mOhm Max). The SDR0604-820KL has higher saturation current (750 mA vs 580 mA), which may provide additional margin in high-current transient conditions.

Q: What packaging formats are available?

A: The PD54R-823K is supplied in Tape & Reel (TR) format. The SDR0604-820KL is available in Cut Tape (CT) and Digi-Reel® formats. Confirm packaging compatibility with your assembly process.

Q: Are both parts RoHS compliant?

A: Yes, both the PD54R-823K and SDR0604-820KL are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Do the dimensional differences affect PCB layout?

A: The PD54R-823K measures 0.224" L x 0.201" W x 0.177" H, while the SDR0604-820KL measures 0.228" L x 0.228" W x 0.189" H. Verify footprint compatibility and clearance requirements before substitution.
