Substitute Part Grouping Explanation

Substitution of the DFE201208K-1R0M=P2 is determined by strict equivalence across the following critical parameters:

Inductance Value: Both parts must maintain 1 µH inductance at 1 MHz test frequency with ±20% tolerance to ensure circuit performance specifications are met.

Package Configuration: Both parts must use the 0805 (2012 Metric) surface mount package with identical physical dimensions (0.079" L x 0.047" W, 2.00mm x 1.20mm) and maximum seated height of 0.031" (0.80mm) to ensure PCB layout compatibility.

Core Type and Shielding: Both parts must employ shielded drum core, wirewound construction with metal core material to maintain electromagnetic isolation and performance characteristics.

Environmental Compliance: Both parts must maintain RoHS3 compliance and MSL 1 rating to satisfy regulatory requirements and manufacturing process compatibility.

Operating Temperature Range: Both parts must support the -40°C to 125°C operating temperature range to ensure functional reliability across specified environmental conditions.

The substitute part DFE21CCN1R0MELL meets all these critical parameters while offering the additional benefit of active product status and enhanced electrical specifications.

Engineering Selection Recommendations

The DFE21CCN1R0MELL is the qualified substitute for the obsolete DFE201208K-1R0M=P2 based on the following engineering criteria:

Product Status: The substitute part maintains active production status with Murata Electronics, ensuring long-term availability and supply chain continuity. The original part's obsolete classification creates supply risk for ongoing production and field support requirements.

Regulatory Compliance: Both parts maintain identical RoHS3 compliance and MSL 1 ratings, ensuring compatibility with current manufacturing processes and environmental regulations without requiring design or procurement modifications.

Electrical and Mechanical Equivalence: The substitute part provides identical inductance value (1 µH), tolerance (±20%), package configuration (0805 2012 Metric), and operating temperature range (-40°C to 125°C). Physical dimensions and mounting characteristics are fully compatible with existing PCB designs.

Enhanced Specifications: The substitute part provides documented electrical specifications including current rating (2.7 A), saturation current (3.3 A), and DC resistance (60 mOhm Max), which were not specified for the original part. These specifications enable more precise circuit design and thermal analysis.

Packaging Availability: The substitute part is available in Tape & Reel (TR) packaging with 2360 pieces in current inventory, compared to limited stock of the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can DFE21CCN1R0MELL be used as a direct replacement for DFE201208K-1R0M=P2 in existing designs?

A: Yes. Both parts share identical inductance (1 µH), tolerance (±20%), package configuration (0805 2012 Metric), physical dimensions, and operating temperature range (-40°C to 125°C). No PCB layout modifications are required for substitution.

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