Key Parameters

Substitute Part Grouping Explanation

Substitution of the DFE201210S-1R5M=P2 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 1.5 µH
• Tolerance: ±20%
• Package / Case: 0805 (2012 Metric)
• Core type: Drum Core, Wirewound
• Shielding: Shielded
• Operating temperature range: -40°C ~ 125°C
• Inductance test frequency: 1 MHz

Acceptable Variation Parameters:

• Current rating and saturation current may vary provided the substitute meets or exceeds the original specification
• DC resistance may vary provided it does not exceed the maximum specified value for the application
• Physical height may vary within the 0805 package constraints

The DFE21CCN1R5MELL qualifies as a direct substitute based on matching inductance, tolerance, package format, core type, shielding, temperature range, and test frequency. This substitute is manufactured by the same supplier and carries active product status.

Parameter Comparison

Engineering Selection Recommendations

The DFE21CCN1R5MELL is the recommended substitute for the obsolete DFE201210S-1R5M=P2. Both components are manufactured by Murata Electronics and share identical electrical specifications for inductance, tolerance, and operating temperature range. The substitute carries active product status, ensuring continued availability and supply chain reliability.

The DFE21CCN1R5MELL features a reduced maximum seated height of 0.031" (0.80mm) compared to the original 0.039" (1.00mm), which may provide design advantages in space-constrained applications while maintaining full compatibility with 0805 package footprints. Both components comply with environmental regulations and carry MSL 1 moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can the DFE21CCN1R5MELL be used as a direct replacement for the DFE201210S-1R5M=P2?

A: Yes. Both components share identical inductance values (1.5 µH), tolerance (±20%), package format (0805 / 2012 Metric), core type (drum core wirewound), shielding configuration, and operating temperature range (-40°C ~ 125°C). The substitute is manufactured by the same supplier and carries active product status.

Q: What is the difference in physical height between these components?

A: The DFE201210S-1R5M=P2 has a maximum seated height of 0.039" (1.00mm), while the DFE21CCN1R5MELL has a maximum seated height of 0.031" (0.80mm). Both fit within the 0805 package specification and are compatible with standard surface mount assembly processes.

Q: Are there any compliance or regulatory differences between these parts?

A: The DFE201210S-1R5M=P2 is ROHS3 compliant. The DFE21CCN1R5MELL carries REACH Unaffected status. Both components have MSL 1 moisture sensitivity ratings and are suitable for standard manufacturing environments.

Q: Why is the original part marked as obsolete?

A: The DFE201210S-1R5M=P2 is obsolete, which is why substitute identification is necessary. The DFE21CCN1R5MELL provides functional and electrical equivalence with active product status, ensuring long-term availability for production and maintenance applications.

Q: Are DC resistance specifications available for the substitute part?

A: DC resistance is not specified for the DFE21CCN1R5MELL in the provided data. The original part specifies a maximum DC resistance of 96 mOhm. Verification of DC resistance performance should be obtained from the manufacturer if this parameter is critical to your application.
