Frequently Asked Questions (FAQ)

Q: Can the DFE252012P-4R7M=P2 be used as a direct replacement for the DFE252012R-H-4R7M=P2?

A: Yes. Both parts share identical inductance (4.7 µH), current rating (1.4 A), tolerance (±20%), core type (shielded drum core wirewound), core material (iron powder), and package dimensions (1008/2520 Metric). The substitute meets or exceeds all electrical specifications of the original part.

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

A: The primary differences are product status (obsolete vs. active), DC resistance (216 mOhm max vs. 200 mOhm max), saturation current (1.7 A vs. 2 A), and operating temperature range (-40°C to 85°C vs. -40°C to 125°C). The substitute part offers improved performance characteristics.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 1008 (2520 Metric) surface mount package with dimensions of 0.098" L x 0.079" W (2.50mm x 2.00mm) and a maximum seated height of 0.047" (1.20mm). PCB footprints are interchangeable.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the DFE252012R-H-4R7M=P2 and DFE252012P-4R7M=P2 are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the inductance tolerance for these parts?

A: Both parts carry a tolerance of ±20%, meaning the actual inductance value will fall within the range of 3.76 µH to 5.64 µH.
