DFE252012PD-1R5M=P2 Equivalent & Substitute Parts

Part Overview

The DFE252012PD-1R5M=P2 is a 1.5 µH shielded drum core wirewound inductor manufactured by Murata Electronics, rated for 2.6 A continuous current with a maximum DC resistance of 60mOhm. This surface mount component in 1008 (2520 Metric) package is designed for applications requiring compact, shielded inductance with flat wire construction and AEC-Q200 automotive qualification. The part is active and in stock, with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching or exceeding the core electrical and mechanical parameters: inductance value, current rating, package dimensions, shielding characteristics, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DFE252012PD-1R5M=P2 are qualified based on the following criteria:

Primary Matching Parameters:

• Inductance: 1.5 µH ±20%
• Package: 1008 (2520 Metric) surface mount
• Shielding: Shielded construction
• Operating Temperature: -40°C to 125°C minimum
• Ratings: AEC-Q200 automotive qualification

Secondary Compatibility Parameters:

• Current Rating: Equal to or greater than 2.6 A
• DC Resistance: Equal to or less than 60 mOhm (lower DCR preferred for reduced losses)
• Saturation Current: Equal to or greater than 3.3 A
• Mounting: Surface mount, tape and reel packaging

Parts meeting all primary parameters and maintaining compatibility within secondary parameters are classified as direct substitutes. Variations in core material (drum core, molded, or metal core) and construction method (wirewound, flat wire) are acceptable provided electrical performance meets or exceeds the specified ratings.

Parameter Comparison

Engineering Selection Recommendations

DFE252012PD-1R5M=P2 (Murata Electronics) - Primary Part Active product status with full inventory availability. ROHS3 compliant with AEC-Q200 automotive rating. Drum core wirewound construction with flat wire design. Suitable for applications requiring the specified 2.6 A current rating and 60 mOhm maximum DC resistance.

MPIA2512V2-1R5-R (Eaton - Electronics Division) - Parametric Equivalent Active product with high inventory availability. AEC-Q200 rated and RoHS compliant. Molded inductor construction with iron powder core. Current rating of 2.3 A is below the primary part specification; DC resistance of 77 mOhm exceeds the primary part maximum. Selection requires verification that application current demand does not exceed 2.3 A and that increased DCR is acceptable for thermal and efficiency considerations.

SRP2512TMA-1R5M (Bourns Inc.) - Recommended Substitute Active product with inventory availability. ROHS3 compliant with AEC-Q200 automotive rating. Metal core construction with flat wire design. Current rating of 3.7 A exceeds primary part specification. DC resistance of 51.6 mOhm is lower than primary part maximum, providing improved efficiency. Extended operating temperature range of -55°C to 150°C provides additional thermal margin. Height dimension of 0.047" matches primary part exactly. This part is suitable for direct substitution in applications where the primary part is unavailable.

Frequently Asked Questions (FAQ)

Q: Can MPIA2512V2-1R5-R be used as a direct substitute for DFE252012PD-1R5M=P2?

A: MPIA2512V2-1R5-R meets the package, inductance, tolerance, shielding, and temperature range requirements. However, the current rating of 2.3 A is lower than the primary part's 2.6 A rating, and DC resistance is higher at 77 mOhm versus 60 mOhm maximum. This part is suitable only if the application current demand does not exceed 2.3 A and increased losses from higher DCR are acceptable.

Q: What are the key differences between the three parts?

A: All three parts share identical inductance (1.5 µH), package dimensions (1008/2520 Metric), and AEC-Q200 rating. The primary differences are: current rating (2.3 A to 3.7 A range), DC resistance (51.6 mOhm to 77 mOhm range), core material (iron powder drum core, iron powder molded, or metal core), and construction method (wirewound with flat wire or molded). SRP2512TMA-1R5M offers the highest current rating and lowest DCR.

Q: Are all substitute parts surface mount compatible with the same PCB footprint?

A: All three parts use the 1008 (2520 Metric) package with identical length and width dimensions of 0.098" x 0.079" (2.50mm x 2.00mm). Height differences are minimal: DFE252012PD-1R5M=P2 and SRP2512TMA-1R5M are 0.047" (1.20mm), while MPIA2512V2-1R5-R is 0.049" (1.25mm). These height variations are within typical PCB assembly tolerances and do not affect footprint compatibility.

Q: Which substitute part offers the best thermal performance?

A: SRP2512TMA-1R5M has the lowest DC resistance at 51.6 mOhm maximum, resulting in the lowest resistive losses and best thermal performance. MPIA2512V2-1R5-R has the highest DC resistance at 77 mOhm, resulting in higher losses and heat generation.

Q: Are all parts RoHS compliant?

A: DFE252012PD-1R5M=P2 and SRP2512TMA-1R5M are ROHS3 compliant. MPIA2512V2-1R5-R is RoHS compliant. All three parts meet RoHS requirements for lead-free construction.
