Substitute Part Grouping Explanation

Substitute parts for the MLF2012DR56MTD25 are qualified based on the following critical parameters:

• Inductance value: 560 nH (exact match required)
• Current rating: 150 mA minimum
• Package / Case: 0805 (2012 Metric) (mechanical compatibility)
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C minimum
• Material - Core: Ferrite
• Shielding: Shielded

The CV201210-R56K from Bourns Inc. meets these substitution criteria. While the DC resistance specification differs (750 mOhm Max versus 550 mOhm Max), both parts maintain the same inductance value, current rating, package dimensions, and thermal operating range. The tolerance specification for the substitute part is ±10%, which is tighter than the ±20% tolerance of the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the MLF2012DR56MTD25 and CV201210-R56K are active production parts with ROHS3 compliance and REACH unaffected status. The MLF2012DR56MTD25 features a lower maximum DC resistance specification of 550 mOhm, while the CV201210-R56K offers a tighter inductance tolerance of ±10% compared to ±20%. Both parts are rated for identical current levels, operating temperature ranges, and package dimensions. Selection between these parts should be based on specific circuit requirements regarding DC resistance and inductance tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can the CV201210-R56K replace the MLF2012DR56MTD25 in all applications?

A: The CV201210-R56K is mechanically and electrically compatible for applications requiring 560 nH inductance at 150 mA. However, the higher DC resistance specification (750 mOhm Max versus 550 mOhm Max) may affect power dissipation characteristics in circuits sensitive to resistive losses. Circuit analysis is necessary to confirm suitability for specific applications.

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

A: The MLF2012DR56MTD25 has a ±20% inductance tolerance, while the CV201210-R56K has ±10%. The tighter tolerance of the substitute part provides greater inductance value consistency. Applications requiring strict inductance specifications may benefit from the substitute part's tighter tolerance.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both parts share identical package dimensions (0805 / 2012 Metric), height specifications (0.057" maximum seated height), and surface mount mounting type. They are compatible with standard PCB assembly equipment and processes.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain MSL 1 (Unlimited) moisture sensitivity rating. The MLF2012DR56MTD25 carries AEC-Q200 certification; the CV201210-R56K does not list this certification in the provided specifications.
