Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PD54R-822M is determined by the following critical parameters:

• Inductance value of 8.2 µH within ±20% tolerance
• Current rating of 1.5 A or greater
• DC resistance not exceeding 95 mOhm
• Ferrite drum core construction, unshielded configuration
• Surface mount nonstandard package
• ROHS3 compliance and REACH unaffected status
• Operating temperature range that encompasses or exceeds -55°C to 125°C

The SDR0604-8R2ML from Bourns Inc. meets these substitution criteria with equivalent inductance, matching current rating, lower DC resistance (90 mOhm), and compatible environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The SDR0604-8R2ML qualifies as a direct substitute for the PD54R-822M based on matching electrical specifications and regulatory compliance. Both components are ROHS3 compliant, REACH unaffected, and maintain MSL 1 moisture sensitivity ratings. The substitute part offers improved saturation current performance (2.3 A versus 1.5 A) and lower DC resistance (90 mOhm versus 95 mOhm), providing enhanced thermal efficiency in equivalent circuit applications. The operating temperature range of the substitute extends to -40°C minimum, which covers the majority of industrial applications; however, applications requiring operation below -40°C must retain the original PD54R-822M specification. Both components are actively produced and available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-8R2ML replace the PD54R-822M in all applications?

A: The SDR0604-8R2ML is electrically and mechanically compatible for applications operating within -40°C to 125°C. Applications requiring operation below -40°C must use the original PD54R-822M, which is rated to -55°C.

Q: What are the key differences between these two inductors?

A: The primary differences are the minimum operating temperature (-40°C for the substitute versus -55°C for the original) and saturation current (2.3 A for the substitute versus 1.5 A for the original). The substitute offers lower DC resistance, resulting in reduced power dissipation.

Q: Are both parts available in the same package?

A: Both components use nonstandard surface mount packages. Physical dimensions differ slightly: PD54R-822M measures 5.70mm × 5.11mm × 4.50mm, while SDR0604-8R2ML measures 5.80mm × 5.80mm × 4.80mm. PCB layout verification is required for mechanical fit confirmation.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the PD54R-822M and SDR0604-8R2ML are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity ratings.

Q: What is the inductance tolerance for these parts?

A: Both inductors maintain ±20% inductance tolerance, ensuring consistent performance across the specified range of 6.56 µH to 9.84 µH.
