Key Parameters

Substitute Part Grouping Explanation

Substitution of the MLF2012C820MT is determined by strict equivalence across the following critical parameters:

Inductance value and tolerance must match or be tighter than the original specification (82 µH ±20%). Current rating must equal or exceed 2 mA. DC resistance must not exceed 3 Ohm maximum. Shielding type must remain shielded. Package and case dimensions must be identical (0805 / 2012 Metric). Q factor and self-resonant frequency characteristics must be maintained. Mounting type must remain surface mount.

The MLF2012C820KTD25 meets all substitution criteria with identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MLF2012C820KTD25 is the direct substitute for the MLF2012C820MT. Both parts are manufactured by TDK Corporation and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part offers improved inductance tolerance (±10% versus ±20%), providing tighter performance characteristics.

The MLF2012C820KTD25 carries Active product status and includes AEC-Q200 automotive qualification rating, whereas the original part is classified as Not For New Designs. This makes the substitute the preferred choice for ongoing production and new designs requiring this inductance value and package configuration.

The operating temperature range of the substitute is narrower (-40°C to 85°C versus -55°C to 125°C). Applications requiring the full extended temperature range of the original part must evaluate whether the substitute's temperature specification is sufficient for the intended operating environment.

Both parts maintain identical RoHS3 compliance, moisture sensitivity level, and physical dimensions, ensuring direct drop-in compatibility in existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MLF2012C820KTD25 be used as a direct replacement for MLF2012C820MT?

A: Yes. Both parts share identical inductance value (82 µH), current rating (2 mA), DC resistance (3 Ohm maximum), shielding type, package dimensions (0805 / 2012 Metric), and Q factor. The substitute is mechanically and electrically compatible for direct PCB substitution.

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

A: The MLF2012C820MT specifies ±20% tolerance, while the MLF2012C820KTD25 specifies ±10% tolerance. The substitute provides tighter inductance accuracy, which may improve circuit performance in applications sensitive to inductance variation.

Q: Are there temperature range limitations when using the substitute?

A: The MLF2012C820KTD25 operates from -40°C to 85°C, compared to the original part's -55°C to 125°C range. Applications requiring operation below -40°C or above 85°C must retain the original MLF2012C820MT or identify alternative parts with extended temperature specifications.

Q: Do both parts have the same physical footprint?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.057" (1.45mm). No PCB layout modifications are required.

Q: What compliance certifications does the substitute carry?

A: The MLF2012C820KTD25 is ROHS3 compliant, MSL Level 1, and carries AEC-Q200 automotive qualification. The original MLF2012C820MT is ROHS3 compliant and MSL Level 1 but does not list AEC-Q200 qualification.
