Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF2012E8R2MT is determined by strict alignment across the following critical parameters:

Electrical Parameters: Inductance value (8.2 µH), current rating (15 mA minimum), and DC resistance (700mOhm maximum) must be maintained or improved. Q factor and self-resonant frequency provide performance consistency.

Mechanical Parameters: Package type (0805/2012 Metric), mounting type (Surface Mount), and physical dimensions (0.079" L x 0.049" W, 1.45mm max height) ensure PCB compatibility without layout modifications.

Material & Construction: Ferrite core material and shielded configuration are required to preserve electromagnetic performance characteristics.

Environmental & Compliance: Operating temperature range (-55°C to 125°C), RoHS3 compliance, and MSL rating (1) must be maintained for regulatory and reliability requirements.

Packaging Format: While the main part uses Tape & Reel (TR) packaging, equivalent parts may use alternative packaging formats (Cut Tape, Bulk) provided all electrical and mechanical specifications align.

Parameter Comparison

The difference in packaging format (Cut Tape versus Tape & Reel) does not affect electrical or mechanical compatibility and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can MLF2012E8R2KT000 be used as a direct replacement for MLF2012E8R2MT?

A: Yes. Both parts share identical inductance (8.2 µH), current rating (15 mA), DC resistance (700mOhm), package type (0805/2012 Metric), operating temperature range (-55°C to 125°C), and all mechanical dimensions. The substitute part is electrically and mechanically compatible without PCB layout modifications.

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

A: The MLF2012E8R2MT has ±20% tolerance, while the MLF2012E8R2KT000 has ±10% tolerance. The tighter tolerance of the substitute part provides improved inductance consistency and may be beneficial for applications with strict performance requirements.

Q: Does the packaging format difference affect compatibility?

A: No. The MLF2012E8R2MT uses Tape & Reel (TR) packaging, while the MLF2012E8R2KT000 uses Cut Tape (CT) packaging. Both formats contain identical components with the same electrical and mechanical specifications. The packaging format is a procurement and assembly consideration only.

Q: Why is MLF2012E8R2MT marked as Not For New Designs?

A: This designation indicates the part is in legacy status within TDK's product portfolio. The MLF2012E8R2KT000, with Active status, represents the current production equivalent and is recommended for new design implementations.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the MLF2012E8R2MT and MLF2012E8R2KT000 are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for industrial and commercial applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on inductance value (8.2 µH), current rating (15 mA), DC resistance (700mOhm maximum), package type (0805/2012 Metric), shielding configuration (Shielded), core material (Ferrite), operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, MSL Level 1).
