Substitute Part Grouping Explanation

Substitution of the DFE201210S-R47M=P2 is determined by strict equivalence across the following critical parameters:

• Inductance value: 470 nH with ±20% tolerance
• Package / Case: 0805 (2012 Metric) surface mount form factor
• Core type and material: Shielded drum core, wirewound with metal core
• Operating temperature range: -40°C to 125°C
• Regulatory compliance: ROHS3 Compliant

The substitute part DFE21CCNR47MELL meets all these criteria while offering improved electrical performance characteristics. Both parts share identical inductance specifications, package dimensions, and environmental operating parameters, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The DFE21CCNR47MELL is the manufacturer-recommended substitute for the obsolete DFE201210S-R47M=P2. Both components are manufactured by Murata Electronics and maintain identical inductance values, package specifications, and operating temperature ranges. The substitute part carries active product status, ensuring continued availability and supply chain support.

The DFE21CCNR47MELL demonstrates improved electrical performance with a higher current rating of 4.1 A compared to 3.4 A in the original part, and reduced DC resistance of 29 mOhm maximum versus 32 mOhm maximum. These improvements provide enhanced thermal performance and lower power dissipation in circuit applications. The substitute maintains full ROHS3 compliance and identical moisture sensitivity classification.

Physical compatibility is confirmed through matching 0805 (2012 Metric) package dimensions and surface mount mounting type. The reduced seated height of 0.031" (0.80mm) on the substitute part compared to 0.039" (1.00mm) on the original presents no compatibility concerns for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can DFE21CCNR47MELL be used as a direct replacement for DFE201210S-R47M=P2?

A: Yes. Both parts share identical inductance values of 470 nH, matching tolerance specifications of ±20%, and are housed in the same 0805 (2012 Metric) surface mount package.
