Substitute Part Grouping Explanation

Substitution of the L0805C3R3MDMIT is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 3.3 µH (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• Shielding: Shielded (electromagnetic performance requirement)
• Material - Core: Ferrite (magnetic characteristics)
• Mounting Type: Surface Mount (assembly compatibility)

Secondary Compatibility Parameters:

• Current Rating: Substitute must meet or exceed 700 mA
• DC Resistance (DCR): Substitute must not exceed 240 mOhm Max
• Tolerance: ±20% (standard tolerance match)
• RoHS3 Compliance: Required for regulatory alignment

The MLZ2012N3R3LT000 from TDK Corporation satisfies all primary matching criteria and exceeds secondary compatibility requirements, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MLZ2012N3R3LT000 is the direct substitute for the L0805C3R3MDMIT. This substitution is supported by the following factors:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current manufacturing standards.

Product Availability: The MLZ2012N3R3LT000 carries Active product status with 21,400 units in stock, compared to the obsolete L0805C3R3MDMIT with limited remaining inventory of 705 units. This availability differential makes the TDK component the practical choice for ongoing production.

Performance Characteristics: The substitute component exceeds the original specification in current rating (750 mA versus 700 mA) and provides superior DC resistance performance (150 mOhm versus 240 mOhm Max). The extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) provides additional thermal margin for demanding applications.

Physical and Electrical Compatibility: Identical package dimensions (0805 / 2012 Metric), inductance value (3.3 µH), tolerance (±20%), and shielding configuration ensure direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the MLZ2012N3R3LT000 be used as a direct replacement for the L0805C3R3MDMIT without PCB modifications?

A: Yes. Both components share identical package dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), identical inductance value (3.3 µH), and identical tolerance (±20%). The MLZ2012N3R3LT000 has a slightly lower seated height (0.041" versus 0.049"), which does not affect PCB compatibility. No design changes are required.

Q: What are the key performance differences between these two inductors?

A: The MLZ2012N3R3LT000 provides improved electrical performance with lower DC resistance (150 mOhm versus 240 mOhm Max), resulting in reduced power dissipation and heat generation. Current rating is higher (750 mA versus 700 mA), and operating temperature range is extended (-55°C ~ 125°C versus -40°C ~ 85°C). These improvements represent enhanced capability without any performance degradation.

Q: Are both components RoHS compliant?

A: Yes. Both the L0805C3R3MDMIT and MLZ2012N3R3LT000 are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components?

A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.

Q: Why is the L0805C3R3MDMIT classified as obsolete?

A: The L0805C3R3MDMIT has been discontinued by KEMET. The MLZ2012N3R3LT000 from TDK Corporation is the recommended active alternative, offering equivalent functionality with enhanced performance characteristics and assured long-term availability.

Q: Are there any frequency-dependent differences between these inductors?

A: The inductance test frequency differs (1 MHz for L0805C3R3MDMIT versus 2 MHz for MLZ2012N3R3LT000). The MLZ2012N3R3LT000 provides additional frequency specification data, including self-resonant frequency (90 MHz) and saturation current (130 mA), enabling more detailed circuit analysis when required.
