Substitute Part Grouping Explanation

Substitute parts for the MLF2012DR68MTD25 are qualified based on the following critical parameters:

• Inductance Value: 680 nH (core electrical specification)
• Package / Case: 0805 (2012 Metric) (mechanical compatibility requirement)
• Current Rating: 150 mA minimum (functional requirement)
• Operating Temperature Range: -55°C ~ 125°C minimum (environmental specification)
• Shielding: Shielded (electromagnetic performance requirement)
• Mounting Type: Surface Mount (assembly compatibility)

The Bourns CV201210-R68K meets all substitution criteria. While the DC resistance specification differs (800 mOhm max versus 600 mOhm max), the inductance value, package, current rating, temperature range, shielding, and mounting type are equivalent. The tolerance specification of ±10% for the substitute part is tighter than the ±20% of the main part, providing improved consistency.

Parameter Comparison

Engineering Selection Recommendations

Both the MLF2012DR68MTD25 and CV201210-R68K are active production components with equivalent compliance certifications. The MLF2012DR68MTD25 features a lower maximum DC resistance specification of 600 mOhm, while the CV201210-R68K specifies 800 mOhm maximum. Selection between these parts should be based on circuit requirements for DC resistance performance. Both components maintain identical inductance values, current ratings, operating temperature ranges, and package dimensions. Both are ROHS3 compliant with MSL 1 rating and REACH unaffected status, supporting use in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the CV201210-R68K replace the MLF2012DR68MTD25 in all applications?

A: The CV201210-R68K is mechanically and electrically compatible for applications where the 800 mOhm maximum DC resistance specification is acceptable. If the circuit design requires the lower 600 mOhm maximum DC resistance of the MLF2012DR68MTD25, the substitute part may not be suitable without circuit re-evaluation.

Q: Are the physical dimensions identical?

A: Yes. Both parts are specified in the 0805 (2012 metric) package with identical length (0.079" / 2.00mm), width (0.049" / 1.25mm), and maximum seated height (0.057" / 1.45mm). They are mechanically interchangeable for PCB assembly.

Q: What is the difference in inductance tolerance between these parts?

A: The MLF2012DR68MTD25 has a tolerance of ±20%, while the CV201210-R68K has a tighter tolerance of ±10%. The tighter tolerance of the substitute part provides improved consistency in inductance value across the production batch.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both components are rated for operating temperatures from -55°C to 125°C, supporting use in industrial and automotive environments within this temperature range.

Q: Do both parts have the same shielding characteristics?

A: Yes. Both the MLF2012DR68MTD25 and CV201210-R68K are shielded multilayer inductors with identical Q factor specifications of 25 @ 25MHz, providing equivalent electromagnetic performance.

Q: What packaging formats are available for these parts?

A: The MLF2012DR68MTD25 is supplied in Tape & Reel (TR) format. The CV201210-R68K is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are standard for surface mount component distribution.
