Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF2012C680MT is determined by strict alignment of the following electrical and mechanical parameters:

Inductance value must match at 68 µH. Current rating must support minimum 2 mA operation. DC resistance must not exceed 2.9Ohm maximum. Package must be identical: 0805 (2012 Metric) surface mount. Shielding type must be shielded construction. Core material must be ferrite. Q factor at 1MHz must be maintained at 25. Self resonant frequency must be 9MHz. Physical dimensions and height must remain within specified tolerances.

The MLF2012C680KT000 meets all these criteria and is designated as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The MLF2012C680KT000 is the direct manufacturer-recommended substitute for the MLF2012C680MT. Both parts are ROHS3 compliant and carry identical MSL ratings. The substitute part offers improved inductance tolerance (±10% versus ±20%), providing tighter performance specifications. However, the operating temperature range of the substitute is narrower (-40°C to 85°C versus -55°C to 125°C). Selection between these parts depends on application temperature requirements. For applications operating within -40°C to 85°C, the MLF2012C680KT000 is preferred due to its active product status and improved tolerance. For applications requiring extended temperature operation below -40°C or above 85°C, the MLF2012C680MT may be necessary, subject to availability constraints given its "Not For New Designs" classification.

Frequently Asked Questions (FAQ)

Q: Can MLF2012C680KT000 be used as a direct replacement for MLF2012C680MT?

A: Yes, within temperature operating range constraints. All electrical parameters, inductance value, current rating, DC resistance, and package dimensions are identical. The substitute has active product status and improved tolerance specifications.

Q: What is the key difference between these two parts?

A: The primary differences are product status and operating temperature range. MLF2012C680MT is classified "Not For New Designs" with -55°C to 125°C operation. MLF2012C680KT000 is active with -40°C to 85°C operation and tighter inductance tolerance (±10% versus ±20%).

Q: Are there any package or footprint differences?

A: No. Both parts use identical 0805 (2012 Metric) surface mount packaging with matching physical dimensions (2.00mm x 1.25mm) and seated height (1.45mm maximum).

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). ECCN classification is EAR99 for both.

Q: Which part should be selected for new designs?

A: MLF2012C680KT000 should be selected for new designs due to its active product status and improved inductance tolerance, provided the operating temperature range of -40°C to 85°C is acceptable for the application.
