Key Parameters

Substitute Part Grouping Explanation

Substitution of the DFE201208S-1R0M=P2 is determined by the following critical parameters:

• Inductance Value: Must be 1 µH to maintain circuit functionality
• Package / Case: Must be 0805 (2012 Metric) for PCB footprint compatibility
• Mounting Type: Must be Surface Mount for assembly compatibility
• Shielding: Must be Shielded to maintain electromagnetic isolation
• Current Rating: Must meet or exceed 2.1 A continuous current requirement
• DC Resistance: Should not exceed 84 mOhm to maintain thermal and efficiency characteristics
• Operating Temperature Range: Must support -40°C ~ 125°C
• Tolerance: ±20% is acceptable

The DFE21CCN1R0MELL qualifies as a direct substitute based on these parameters, with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DFE21CCN1R0MELL is the manufacturer-recommended substitute for the obsolete DFE201208S-1R0M=P2. Both components maintain identical mechanical compatibility with 0805 (2012 Metric) footprints and identical physical dimensions. The substitute part is currently in active production status with improved electrical performance: higher current rating (2.7 A vs. 2.1 A), higher saturation current (3.3 A vs. 2.7 A), and lower DC resistance (60 mOhm vs. 84 mOhm). Both parts are ROHS3 compliant and maintain the same operating temperature range. The substitute part offers superior thermal performance and current handling capacity while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DFE21CCN1R0MELL be used as a direct replacement for DFE201208S-1R0M=P2?

A: Yes. Both parts share identical inductance (1 µH), package (0805 / 2012 Metric), physical dimensions, and operating temperature range. The substitute part meets all mechanical and electrical requirements of the original part.

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

A: The substitute part DFE21CCN1R0MELL provides improved performance with higher current rating (2.7 A vs. 2.1 A), higher saturation current (3.3 A vs. 2.7 A), and lower DC resistance (60 mOhm vs. 84 mOhm). The original part is obsolete while the substitute is in active production.

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

A: No. Lower DC resistance is a performance improvement that reduces power dissipation and heat generation. This is beneficial for circuit reliability and efficiency.

Q: Are there any packaging differences between these parts?

A: No. Both parts use identical 0805 (2012 Metric) surface mount packaging with the same physical dimensions (2.00mm L x 1.20mm W x 0.80mm H max).

Q: Are both parts RoHS compliant?

A: Yes. Both DFE201208S-1R0M=P2 and DFE21CCN1R0MELL are ROHS3 compliant with MSL rating of 1 (Unlimited).
