Key Parameters

Substitute Part Grouping Explanation

The SDR0604-2R7ML (Bourns Inc.) qualifies as a direct substitute for the PD54R-272M based on the following critical electrical and mechanical parameters:

Key Parameters for Substitution:

• Inductance Value: Both parts are rated at 2.7 µH with ±20% tolerance
• Core Type: Both are ferrite drum core, wirewound, unshielded inductors
• Current Rating: The substitute is rated at 2.3 A, which exceeds the main part's 2.2 A requirement
• DC Resistance: The substitute offers 60mOhm Max, which is lower than the main part's 67mOhm Max
• Surface Mount Configuration: Both components use surface mount packaging
• RoHS3 Compliance: Both parts meet RoHS3 requirements
• Moisture Sensitivity Level: Both are classified as MSL 1 (Unlimited)

The substitute maintains electrical compatibility while offering improved performance characteristics in current handling and DC resistance.

Parameter Comparison

Engineering Selection Recommendations

Both the PD54R-272M and SDR0604-2R7ML are active production components with full RoHS3 compliance and MSL 1 ratings, ensuring compatibility with standard manufacturing and supply chain requirements.

The SDR0604-2R7ML offers technical advantages in current handling (2.3 A vs. 2.2 A) and lower DC resistance (60mOhm Max vs. 67mOhm Max). Selection between these parts should be based on application-specific requirements and supply chain availability. The SDR0604-2R7ML maintains electrical equivalence for the specified 2.7 µH inductance value while providing additional performance margin.

Note that the PD54R-272M supports a lower operating temperature minimum (-55°C vs. -40°C), which may be relevant for applications requiring extended temperature range operation.

Frequently Asked Questions (FAQ)

Q: What makes the SDR0604-2R7ML a valid substitute for the PD54R-272M?

A: Both components share the same inductance value (2.7 µH), tolerance (±20%), ferrite drum core construction, unshielded configuration, and surface mount packaging. The substitute meets or exceeds the electrical requirements with a higher current rating and lower DC resistance.

Q: Are there physical dimension differences between these parts?

A: Yes. The PD54R-272M measures 0.224" L x 0.201" W x 0.177" H (5.70mm x 5.11mm x 4.50mm), while the SDR0604-2R7ML measures 0.228" L x 0.228" W x 0.189" H (5.80mm x 5.80mm x 4.80mm). PCB footprint verification is required prior to implementation.

Q: What is the temperature range difference?

A: The PD54R-272M operates from -55°C to 125°C, while the SDR0604-2R7ML operates from -40°C to 125°C. The substitute part has a narrower lower temperature limit. Applications requiring temperatures below -40°C must retain the PD54R-272M.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the PD54R-272M and SDR0604-2R7ML are RoHS3 compliant with MSL 1 moisture sensitivity ratings.

Q: What is the DC resistance advantage of the substitute?

A: The SDR0604-2R7ML offers 60mOhm Max compared to the PD54R-272M's 67mOhm Max, resulting in lower resistive losses and reduced heat dissipation in the component.
