Substitute Part Grouping Explanation

Substitution of the DFE252012R-H-2R2M=P2 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 2.2 µH (with ±20% tolerance band)
• Package / Case: 1008 (2520 Metric) surface mount form factor
• Core Type: Shielded drum core wirewound construction
• Core Material: Iron powder composition
• Mounting Type: Surface mount technology (SMT)
• RoHS Compliance: ROHS3 Compliant status
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute part DFE252012P-2R2M=P2 meets all mandatory substitution criteria. Variations in current rating, saturation current, DC resistance, and operating temperature range are within acceptable engineering tolerances for this product category and do not preclude functional equivalence in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The DFE252012P-2R2M=P2 is the direct equivalent substitute for the obsolete DFE252012R-H-2R2M=P2. Both components are manufactured by Murata Electronics and maintain identical inductance values, package dimensions, and core construction specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute part demonstrates improved electrical performance characteristics: higher current rating (2.2 A versus 2 A), higher saturation current (3 A versus 2.4 A), and lower DC resistance (84 mOhm Max versus 90 mOhm Max). The extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) provides additional thermal margin for demanding applications. Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity classification, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can DFE252012P-2R2M=P2 be used as a direct replacement for DFE252012R-H-2R2M=P2?

A: Yes. Both parts share identical inductance values (2.2 µH), package specifications (1008 / 2520 Metric), core materials (iron powder shielded drum core), and mounting technology (surface mount). The substitute part is electrically and mechanically compatible for applications originally designed for the main part.

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

A: The substitute part offers improved electrical performance with higher current rating (2.2 A vs. 2 A), higher saturation current (3 A vs. 2.4 A), lower DC resistance (84 mOhm vs. 90 mOhm), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C). The main part is obsolete; the substitute is in active production.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in the 1008 (2520 Metric) form factor with identical length (0.098" / 2.50mm), width (0.079" / 2.00mm), and maximum seated height (0.047" / 1.20mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DFE252012R-H-2R2M=P2 and DFE252012P-2R2M=P2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the inductance tolerance for these parts?

A: Both parts have an inductance tolerance of ±20%, meaning the actual inductance value will fall within the range of 1.76 µH to 2.64 µH.
