Engineering Selection Recommendations

The DFE21CCN2R2MELL is the manufacturer-recommended substitute for the obsolete DFE201208S-2R2M=P2. Both components are ROHS3 compliant and maintain identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

The substitute part provides enhanced electrical performance with a higher current rating (1.8 A versus 1.4 A) and improved saturation current (2.1 A versus 1.8 A), while simultaneously reducing DC resistance from 204 mOhm to 138 mOhm. These improvements result in lower power dissipation and greater design margin for current-limited applications.

The DFE21CCN2R2MELL maintains full mechanical and electrical compatibility with the original part, including identical package dimensions, mounting type, and operating temperature range. The active production status of the substitute ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the DFE21CCN2R2MELL be used as a direct replacement for the DFE201208S-2R2M=P2?

A: Yes. Both components share identical inductance values (2.2 µH), tolerance (±20%), package type (0805 / 2012 Metric), physical dimensions, and operating temperature range (-40°C to 125°C). The substitute is electrically and mechanically compatible for direct board-level substitution.

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

A: The primary differences are product status and electrical performance. The DFE201208S-2R2M=P2 is obsolete, while the DFE21CCN2R2MELL is in active production. The substitute offers higher current rating (1.8 A vs. 1.4 A), higher saturation current (2.1 A vs. 1.8 A), and lower DC resistance (138 mOhm vs. 204 mOhm).

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory and environmental compliance requirements are equivalent.

Q: Will the lower DC resistance of the substitute affect circuit performance?

A: Lower DC resistance reduces power dissipation and heat generation in the inductor, which is a beneficial characteristic. This does not negatively impact circuit function and improves thermal performance.

Q: Is the substitute available in the same packaging format?

A: The DFE21CCN2R2MELL is supplied in Tape & Reel (TR) packaging, while the original part information does not specify packaging format. Both use the identical 0805 (2012 Metric) component package for surface mount assembly.
