Substitute Part Grouping Explanation

Substitution of the DFE201210S-R47MS=P2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 470 nH
• Inductance tolerance: ±20%
• Package / Case: 0805 (2012 Metric)
• Mounting type: Surface Mount
• Core type: Drum Core, Wirewound
• Core material: Metal
• Shielding: Shielded
• Operating temperature range: -40°C ~ 125°C
• RoHS3 compliance

Allowable Parameter Variations: Substitute parts may exceed the original current rating and saturation current specifications, provided all other parameters remain equivalent. Similarly, DC resistance may be lower than the original maximum specification. These improvements do not compromise circuit compatibility and may enhance performance margins.

The DFE21CCNR47MELL qualifies as a direct substitute based on full alignment with all mandatory parameters and improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DFE21CCNR47MELL is the qualified substitute for the obsolete DFE201210S-R47MS=P2. Selection of this substitute is supported by the following factors:

Product Status: The DFE21CCNR47MELL carries an Active product status, ensuring continued availability and manufacturing support from Murata Electronics. The original part is classified as Obsolete, making the active substitute the appropriate choice for new designs and ongoing production.

Regulatory Compliance: Both parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, confirming equivalent environmental and handling requirements.

Electrical Performance: The substitute part delivers improved electrical characteristics. The current rating increases from 3.4 A to 4.1 A, and DC resistance decreases from 32 mOhm maximum to 29 mOhm maximum. These improvements provide enhanced performance margins without introducing any compatibility concerns.

Physical Compatibility: The substitute maintains identical footprint dimensions (0.079" L x 0.047" W / 2.00mm x 1.20mm) and mounting type, ensuring direct PCB layout compatibility. The seated height is reduced from 1.00mm to 0.80mm, which presents no clearance issues in standard applications.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for production environments and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the DFE21CCNR47MELL be used as a direct replacement for the DFE201210S-R47MS=P2 on existing PCBs?

A: Yes. The DFE21CCNR47MELL is a direct substitute. Both parts share identical inductance values (470 nH), tolerance (±20%), package dimensions (0805 / 2012 Metric), and mounting type (Surface Mount). The footprint and electrical specifications are fully compatible.

Q: What are the differences between these two parts?

A: The primary differences are product status and electrical performance. The DFE21CCNR47MELL is an active product with improved current rating (4.1 A versus 3.4 A) and lower DC resistance (29 mOhm maximum versus 32 mOhm maximum). The substitute also features a reduced seated height (0.80mm versus 1.00mm). These differences represent improvements that do not compromise compatibility.

Q: Why is the original part classified as obsolete?

A: The DFE201210S-R47MS=P2 is listed as obsolete by Murata Electronics. The DFE21CCNR47MELL represents the current active equivalent in the product line.

Q: Are there any thermal or frequency-related differences between these parts?

A: Both parts operate across the identical temperature range (-40°C to 125°C) and are tested at 1 MHz for inductance verification. No thermal or frequency-related differences exist between the two parts.

Q: Does the reduced seated height of the substitute part affect PCB assembly?

A: No. The reduced seated height (0.80mm versus 1.00mm) presents no assembly or clearance concerns. This represents a dimensional improvement that is compatible with standard PCB designs.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the DFE201210S-R47MS=P2 and DFE21CCNR47MELL are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging formats are available for each part?

A: The original DFE201210S-R47MS=P2 is supplied in bulk packaging. The substitute DFE21CCNR47MELL is supplied in Tape & Reel (TR) format, which is standard for production and automated assembly environments.
