• Current Rating: Both rated at 1.1 A
• Package / Case: Identical 1008 (2520 Metric) surface mount package
• Physical Dimensions: Matching 0.098" L x 0.079" W (2.50mm x 2.00mm) with 0.039" (1.00mm) maximum seated height
• Core Type: Both utilize shielded drum core wirewound construction with iron powder core material
• RoHS Compliance: Both ROHS3 compliant
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)

The substitute part maintains electrical and mechanical compatibility within the specified tolerance and performance envelope for this inductor category.

Parameter Comparison

Engineering Selection Recommendations

The DFE252010P-4R7M=P2 is the appropriate substitute for the obsolete DFE252010R-H-4R7M=P2. Both parts are manufactured by Murata Electronics and maintain ROHS3 compliance. The substitute part offers improved saturation current (1.7 A versus 1.4 A) and lower DC resistance (270 mOhm versus 276 mOhm), while maintaining identical inductance, current rating, and package specifications. The extended operating temperature range of the substitute (-40°C to 125°C versus -40°C to 85°C) provides additional thermal margin. The substitute part is currently in active production status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can DFE252010P-4R7M=P2 be used as a direct replacement for DFE252010R-H-4R7M=P2?

A: Yes. Both parts share identical inductance (4.7 µH), current rating (1.1 A), tolerance (±20%), package (1008/2520 Metric), and physical dimensions. The substitute meets or exceeds the electrical specifications of the original part.

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

A: The primary differences are product status (substitute is active versus original is obsolete), saturation current (1.7 A versus 1.4 A), DC resistance (270 mOhm versus 276 mOhm), and operating temperature range (-40°C to 125°C versus -40°C to 85°C). These differences favor the substitute part.

Q: Are the package and mounting specifications identical?

A: Yes. Both parts use the 1008 (2520 Metric) surface mount package with identical physical dimensions of 0.098" L x 0.079" W and maximum seated height of 0.039" (1.00mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both DFE252010R-H-4R7M=P2 and DFE252010P-4R7M=P2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the inductance tolerance for these parts?

A: Both parts are specified with ±20% inductance tolerance at 1 MHz test frequency.
