Substitute Part Grouping Explanation

Substitute parts for the MLF2012DR47MTD25 are qualified based on the following critical parameters:

  • Inductance Value: 470 nH (exact match required)
  • Current Rating: 200 mA minimum
  • Package / Case: 0805 (2012 Metric) form factor
  • Shielding Type: Shielded construction
  • Operating Temperature Range: -55°C ~ 125°C minimum coverage
  • Mounting Type: Surface Mount

The Bourns CV201210-R47K meets these core substitution criteria. While the DC resistance specification differs (650mOhm Max versus 500mOhm Max), the inductance value, current rating, package dimensions, shielding, and operating temperature range remain compatible with the original part's functional requirements.

Engineering Selection Recommendations

Both the MLF2012DR47MTD25 and CV201210-R47K maintain Active product status and satisfy RoHS3 compliance requirements. The Bourns CV201210-R47K offers tighter inductance tolerance (±10% versus ±20%), which may provide improved circuit performance in applications requiring closer value matching. The increased DC resistance specification of the Bourns part (650mOhm Max) should be evaluated against circuit thermal and efficiency requirements. Both components are classified as REACH Unaffected and carry EAR99 export classification. Selection between these parts should be based on specific application requirements regarding DC resistance, tolerance specifications, and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can the CV201210-R47K directly replace the MLF2012DR47MTD25 in all applications?

A: Both parts share identical inductance values, current ratings, package dimensions, and operating temperature ranges. The primary difference is DC resistance specification (650mOhm Max versus 500mOhm Max). Applications sensitive to resistive losses should evaluate this parameter against circuit requirements.

Q: What is the significance of the tolerance difference between these parts?

A: The MLF2012DR47MTD25 specifies ±20% tolerance while the CV201210-R47K specifies ±10% tolerance. Tighter tolerance may benefit circuits requiring precise inductance values, though both parts meet the same 470 nH nominal specification.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in the 0805 (2012 Metric) form factor with identical length (0.079"), width (0.049"), and maximum seated height (0.057"). PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Both the MLF2012DR47MTD25 and CV201210-R47K are RoHS3 compliant, REACH Unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: What is the difference in self-resonant frequency?

A: The MLF2012DR47MTD25 specifies 160MHz self-resonant frequency while the CV201210-R47K specifies 125MHz. This difference should be considered in high-frequency applications where resonant behavior impacts circuit performance.
