Substitute Part Grouping Explanation

Substitution of the DFE201210S-2R2M=P2 is determined by strict equivalence across the following critical parameters:

Inductance Value: 2.2 µH (exact match required)

Package / Case: 0805 (2012 Metric) surface mount package (exact match required)

Core Type & Shielding: Drum core, wirewound construction with shielding (exact match required)

Current Rating: Minimum 1.5 A continuous current capability

DC Resistance: Maximum 155mOhm (lower values acceptable)

Saturation Current: Minimum 2.1 A

Operating Temperature Range: -40°C to 125°C (minimum requirement)

Compliance: ROHS3 compliant

The substitute part DFE21CCN2R2MELL meets all substitution criteria with improved electrical characteristics, including higher current rating (1.8 A) and lower DC resistance (138mOhm Max), while maintaining identical inductance, package, and core specifications.

Parameter Comparison

Engineering Selection Recommendations

The DFE21CCN2R2MELL is the manufacturer-recommended substitute for the obsolete DFE201210S-2R2M=P2. Both components are manufactured by Murata Electronics and maintain identical inductance, package, and core specifications. The substitute part offers improved electrical performance with higher current rating (1.8 A versus 1.5 A) and reduced DC resistance (138mOhm versus 155mOhm), making it a direct drop-in replacement with enhanced capability margins.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage requirements. The substitute part's active product status ensures long-term availability and supply chain continuity, addressing the obsolescence of the original component.

The reduced seated height of the substitute part (0.031" versus 0.039") presents no compatibility concerns for standard PCB assembly processes and may provide marginal benefits for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can DFE21CCN2R2MELL be used as a direct replacement for DFE201210S-2R2M=P2?

A: Yes. Both components share identical inductance (2.2 µH), package (0805 / 2012 Metric), core type (shielded drum core wirewound), and operating temperature range (-40°C to 125°C). The substitute part exceeds the original specifications with higher current rating and lower DC resistance, making it a direct drop-in replacement.

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

A: The primary differences are product status (obsolete versus active), current rating (1.5 A versus 1.8 A), DC resistance (155mOhm versus 138mOhm), and seated height (1.00mm versus 0.80mm). All differences favor the substitute part with improved electrical performance and reduced height.

Q: Are there any PCB layout or assembly considerations when switching to the substitute part?

A: No layout modifications are required. Both parts use identical 0805 (2012 Metric) package dimensions and footprints. The reduced seated height of the substitute part (0.80mm versus 1.00mm) is compatible with standard reflow soldering processes and does not require assembly parameter adjustments.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both components are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity), and operate across -40°C to 125°C. Both are classified under ECCN EAR99 and HTSUS 8504.50.8000.

Q: Why is the original part obsolete?

A: The DFE201210S-2R2M=P2 has been discontinued by Murata Electronics. The DFE21CCN2R2MELL represents the active product line continuation with equivalent functionality and improved specifications.
