Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF2012A2R2KTD25 is determined by the following critical parameters:

• Inductance Value: Must match 2.2 µH within the ±10% tolerance band
• Package Dimensions: Must be 0805 (2012 metric) for PCB footprint compatibility
• Shielding Type: Must be shielded to maintain electromagnetic isolation
• Core Material: Ferrite construction required
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Mounting Type: Surface mount configuration required
• RoHS Compliance: ROHS3 compliance required

The Bourns CV201210-2R2K meets these substitution criteria. While the current rating (30 mA) and DC resistance (650mOhm max) differ from the main part, these parameters remain within acceptable substitution boundaries for applications where the lower current rating and higher resistance do not exceed circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MLF2012A2R2KTD25 and CV201210-2R2K maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. The MLF2012A2R2KTD25 carries AEC-Q200 automotive qualification, which the CV201210-2R2K does not specify. Selection between these parts depends on application-specific current and resistance requirements. The MLF2012A2R2KTD25 supports higher current capacity (50 mA vs. 30 mA) and lower DC resistance (500mOhm vs. 650mOhm), making it suitable for applications with stricter power dissipation constraints. The CV201210-2R2K remains functionally equivalent for circuits operating within its 30 mA current limit and accepting the higher resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CV201210-2R2K replace the MLF2012A2R2KTD25 in all applications?

A: The CV201210-2R2K is electrically equivalent for inductance value and frequency response. However, the lower current rating (30 mA vs. 50 mA) and higher DC resistance (650mOhm vs. 500mOhm) must be evaluated against circuit requirements. Applications drawing more than 30 mA or requiring lower resistance characteristics require the MLF2012A2R2KTD25.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0805 (2012 metric) package with identical length (2.00mm), width (1.25mm), and maximum seated height (1.05mm). PCB footprints are directly compatible.

Q: What is the significance of the AEC-Q200 rating on the MLF2012A2R2KTD25?

A: AEC-Q200 certification indicates the part meets automotive-grade reliability standards. Applications requiring automotive qualification must use the MLF2012A2R2KTD25, as the CV201210-2R2K does not specify this certification.

Q: Do both parts have the same self-resonant frequency?

A: No. The MLF2012A2R2KTD25 has a self-resonant frequency of 80MHz, while the CV201210-2R2K is rated at 50MHz. Applications operating near or above 50MHz should use the MLF2012A2R2KTD25 to maintain performance margin.

Q: Are there any temperature range differences?

A: Both parts operate across -55°C to 125°C. Temperature performance is equivalent.
