Key Parameters

Substitute Part Grouping Explanation

Substitution of the DFE252012R-H-1R0M=P2 is determined by strict equivalence across the following critical parameters:

• Inductance Value: Must be 1 µH
• Package / Case: Must be 1008 (2520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount
• Core Type: Must be Drum Core, Wirewound with Iron Powder material
• Shielding: Must be Shielded
• Tolerance: Must be ±20%

The substitute part DFE252012P-1R0M=P2 meets all these criteria. Additional considerations include current rating, DC resistance, saturation current, and operating temperature range, which may vary within acceptable limits for the application.

Parameter Comparison

Engineering Selection Recommendations

The DFE252012P-1R0M=P2 is the direct substitute for the obsolete DFE252012R-H-1R0M=P2. Both parts are manufactured by Murata Electronics and maintain identical inductance, tolerance, package dimensions, and core construction. The substitute part offers improved electrical performance with lower DC resistance (42 mOhm versus 49 mOhm), higher saturation current (4.3 A versus 3.4 A), and an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). Both parts are ROHS3 compliant with MSL 1 rating. The active product status of the DFE252012P-1R0M=P2 ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the DFE252012P-1R0M=P2 be used as a direct replacement for the DFE252012R-H-1R0M=P2?

A: Yes. Both parts share identical inductance (1 µH), tolerance (±20%), package (1008 / 2520 Metric), mounting type (Surface Mount), core construction (Drum Core, Wirewound, Iron Powder), and shielding. The substitute part is electrically and mechanically compatible.

Q: What are the differences between these two parts?

A: The DFE252012P-1R0M=P2 provides lower DC resistance (42 mOhm versus 49 mOhm), higher saturation current (4.3 A versus 3.4 A), higher continuous current rating (3.2 A versus 3.1 A), and an extended operating temperature range (up to 125°C versus 85°C). The substitute part is currently in active production status.

Q: Are there any package or footprint differences?

A: No. Both parts use the identical 1008 (2520 Metric) package with the same physical dimensions (0.098" L x 0.079" W / 2.50mm x 2.00mm) and seated height (0.047" / 1.20mm). PCB footprints are interchangeable.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The substitute part includes REACH Unaffected status.

Q: Why is the original part listed as obsolete?

A: The DFE252012R-H-1R0M=P2 has been discontinued by Murata Electronics. The DFE252012P-1R0M=P2 serves as the active replacement with equivalent specifications and improved performance characteristics.
