Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DFE252012P-1R0M=P2 is determined by the following critical parameters:

• Inductance Value: Must be 1 µH with ±20% tolerance
• Current Rating: Minimum 3.2 A continuous current capability
• Current Saturation (Isat): Minimum 4.3 A
• DC Resistance (DCR): Maximum 42 mOhm
• Package / Case: 1008 (2520 Metric) surface mount format
• Shielding: Shielded configuration required
• Operating Temperature Range: -40°C ~ 125°C minimum
• Inductance Test Frequency: 1 MHz

The substitute part MPI2512V2-1R0-R from Eaton - Electronics Division meets all critical substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both components maintain Active product status and meet RoHS compliance requirements. The MPI2512V2-1R0-R substitute provides equivalent electrical performance with a 0.1 A higher current rating (3.3 A vs. 3.2 A) and 0.1 A higher saturation current (4.4 A vs. 4.3 A), while maintaining the same inductance value and tolerance specification. The DC resistance differential of 2 mOhm (44 mOhm vs. 42 mOhm maximum) remains within acceptable design margins for most applications.

Physical compatibility is confirmed through identical footprint dimensions (0.098" L x 0.079" W) and matching 1008 (2520 Metric) package specifications. The height differential of 0.002" (0.05mm) between seated heights does not impact PCB assembly or clearance requirements for standard surface mount applications.

Both parts operate across the full -40°C to 125°C industrial temperature range and maintain unlimited moisture sensitivity classification (MSL 1), ensuring equivalent reliability in standard manufacturing and storage environments.

Frequently Asked Questions (FAQ)

Q: Can MPI2512V2-1R0-R be used as a direct replacement for DFE252012P-1R0M=P2?

A: Yes. Both components share identical inductance values (1 µH), tolerance specifications (±20%), package format (1008/2520 Metric), and operating temperature range (-40°C to 125°C). The substitute meets or exceeds all critical electrical parameters including current rating, saturation current, and DC resistance specifications.

Q: What is the significance of the 2 mOhm difference in DC resistance?

A: The DFE252012P-1R0M=P2 specifies 42 mOhm maximum DC resistance, while the MPI2512V2-1R0-R specifies 44 mOhm maximum. This 2 mOhm differential represents approximately 4.8% variance and remains within acceptable design tolerances for inductor substitution in standard power conversion and filtering applications.

Q: Are there any PCB layout considerations when switching between these parts?

A: No. Both components use identical footprint dimensions (0.098" L x 0.079" W / 2.50mm x 2.00mm) and the same 1008 (2520 Metric) surface mount package. The 0.002" (0.05mm) height difference does not require PCB layout modifications or clearance adjustments.

Q: Do both parts meet the same compliance standards?

A: Both components are RoHS compliant and maintain MSL 1 (Unlimited) moisture sensitivity ratings. The DFE252012P-1R0M=P2 carries RoHS3 certification, while the MPI2512V2-1R0-R carries RoHS certification. Both meet industrial reliability and environmental compliance requirements.

Q: What is the frequency test specification and does it affect substitution?

A: Both parts are tested for inductance value at 1 MHz. This standardized test frequency ensures consistent inductance measurement across manufacturers and does not impact substitution eligibility. The MPI2512V2-1R0-R additionally specifies a self-resonant frequency of 70 MHz, providing additional frequency response characterization.
