Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DFE252010F-3R3M=P2 is determined by strict alignment of the following critical parameters:

Inductance value must be 3.3 µH with tolerance of ±20%. Current rating must be 1.6 A or higher. DC resistance must not exceed 170 mOhm. Package must be 1008 (2520 Metric) surface mount. Shielding configuration must be shielded. Operating temperature range must encompass -40°C to 125°C. Inductance test frequency must be 1 MHz.

The substitute part MPI2510V2-3R3-R from Eaton - Electronics Division meets all critical substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MPI2510V2-3R3-R is a direct substitute for the DFE252010F-3R3M=P2 based on electrical and mechanical parameter equivalence. Both parts are active production components with RoHS compliance and identical moisture sensitivity ratings. The Eaton part exhibits a saturation current of 2.1 A compared to 2.2 A for the Murata part, representing a 0.1 A difference within acceptable design margins for applications operating at or below the 1.6 A rated current. The maximum seated height difference of 0.002" (0.05mm) is negligible for standard PCB assembly processes and does not impact board layout or thermal management considerations.

Selection between these parts should be based on availability, lead time, cost, and established supplier relationships. Both parts satisfy the same electrical specifications and environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the MPI2510V2-3R3-R be used as a direct replacement for the DFE252010F-3R3M=P2 in existing designs?

A: Yes. Both parts share identical inductance values, current ratings, DC resistance specifications, package dimensions, and operating temperature ranges. The parts are mechanically and electrically interchangeable for applications designed around the DFE252010F-3R3M=P2 specifications.

Q: What is the significance of the saturation current difference between the two parts?

A: The DFE252010F-3R3M=P2 has a saturation current of 2.2 A while the MPI2510V2-3R3-R has 2.1 A. Since both parts are rated for 1.6 A continuous current, this 0.1 A difference does not affect performance in applications operating within the rated current specification.

Q: Are there any height considerations when substituting these parts?

A: The Murata part has a maximum seated height of 0.039" (1.00mm) while the Eaton part is 0.041" (1.05mm). This 0.002" (0.05mm) difference is within standard PCB assembly tolerances and does not require design modifications.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant, carry EAR99 ECCN classification, and share identical HTSUS codes. Both have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What parameters must remain constant when selecting a substitute inductor?

A: Critical parameters that must match are inductance value (3.3 µH), inductance tolerance (±20%), current rating (1.6 A minimum), DC resistance (170 mOhm maximum), package format (1008/2520 Metric), shielding configuration (shielded), and operating temperature range (-40°C to 125°C).
