Engineering Selection Recommendations

The DFE252010P-2R2M=P2 is the direct equivalent substitute for the obsolete DFE252010R-H-2R2M=P2. Both components are manufactured by Murata Electronics and maintain identical electrical and mechanical specifications across all critical parameters.

The substitute part offers measurable improvements: reduced DC resistance (115 mOhm versus 126 mOhm), increased saturation current (2.6 A versus 2.1 A), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). These enhancements provide superior performance margins without compromising compatibility.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility. The substitute part is currently in active production status with substantial inventory availability, eliminating supply chain risk associated with the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the DFE252010P-2R2M=P2 be used as a direct replacement for the DFE252010R-H-2R2M=P2?

A: Yes. Both components share identical inductance (2.2 µH), tolerance (±20%), current rating (1.7 A), core type (drum core, wirewound), core material (iron powder), shielding (shielded), package (1008/2520 Metric), and mounting type (surface mount). The substitute part meets or exceeds all electrical and mechanical requirements.

Q: What are the differences between these two parts?

A: The substitute part features lower DC resistance (115 mOhm versus 126 mOhm), higher saturation current (2.6 A versus 2.1 A), and an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). These represent performance improvements with no compatibility impact.

Q: Are there packaging format differences between these parts?

A: The original part is supplied in Cut Tape (CT) & Digi-Reel® format, while the substitute is supplied in Tape & Reel (TR) format. Both formats are standard surface mount packaging and do not affect component functionality or PCB assembly compatibility.

Q: Why is the original part obsolete?

A: The DFE252010R-H-2R2M=P2 has been discontinued by Murata Electronics. The DFE252010P-2R2M=P2 represents the current production equivalent with enhanced specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the DFE252010R-H-2R2M=P2 and DFE252010P-2R2M=P2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
