Engineering Selection Recommendations

The DFE252010P-1R5M=P2 is the direct active equivalent for the obsolete DFE252010R-H-1R5M=P2. Both components are manufactured by Murata Electronics and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part offers improved performance characteristics with lower DC resistance (82mOhm vs. 90mOhm) and higher saturation current (3A vs. 2.3A), while maintaining full backward compatibility.

Both parts carry ROHS3 compliance and EAR99 export classification. The substitute part's extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) provides additional thermal margin for applications operating at elevated ambient conditions. The active product status of DFE252010P-1R5M=P2 ensures reliable supply chain availability and long-term component sourcing for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can DFE252010P-1R5M=P2 be used as a direct replacement for DFE252010R-H-1R5M=P2?

A: Yes. Both components share identical inductance (1.5 µH), current rating (2.1 A), tolerance (±20%), core type, shielding, package (1008/2520 Metric), and physical dimensions. The substitute part is electrically and mechanically compatible for direct PCB substitution.

Q: What are the differences between these two parts?

A: The primary differences are product status and performance enhancements. DFE252010P-1R5M=P2 is active (versus obsolete), features lower DC resistance (82mOhm max versus 90mOhm max), higher saturation current (3A versus 2.3A), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). These represent improvements over the original specification.

Q: Are there packaging differences?

A: No. Both parts use identical 1008 (2520 Metric) surface mount packaging with matching physical dimensions (0.098" L x 0.079" W x 0.039" Max Height) and flat wire construction.

Q: Do both parts meet RoHS requirements?

A: Yes. Both DFE252010R-H-1R5M=P2 and DFE252010P-1R5M=P2 are ROHS3 compliant with MSL rating of 1 (Unlimited).
