Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806C2R2MDMIT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 2.2 µH
• Current rating: 1.2 A minimum
• Package / Case: 0806 (2016 Metric)
• Shielding type: Shielded
• Core material: Ferrite
• Mounting type: Surface Mount
• Tolerance: ±20%

Allowable Variation Parameters:

• DC Resistance (DCR): Substitute must not exceed the original specification
• Operating temperature range: Substitute may exceed the original range
• Product status: Active alternatives are preferred for obsolete parts

The LQM2MPN2R2MG0L from Murata Electronics satisfies all mandatory matching parameters and demonstrates superior or equivalent performance across allowable variation parameters.

Engineering Selection Recommendations

The LQM2MPN2R2MG0L from Murata Electronics is a direct functional equivalent for the obsolete L0806C2R2MDMIT. Selection of this substitute is supported by the following engineering factors:

Compliance & Certification Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental restrictions.

Product Status Advantage: The substitute part carries active product status, providing assured long-term availability and manufacturing support compared to the obsolete original part.

Performance Characteristics: The substitute delivers equivalent or superior electrical performance. DC resistance of 138mOhm is lower than the original 140mOhm maximum specification, reducing resistive losses. The extended operating temperature range of -55°C to 125°C encompasses the original -40°C to 85°C specification, providing thermal margin for demanding applications.

Physical & Mechanical Compatibility: Identical package dimensions (0806 / 2016 Metric), footprint, and mounting characteristics ensure direct board-level substitution without layout modifications.

Electrical Equivalence: Inductance value, current rating, tolerance, and shielding characteristics are identical, confirming functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the LQM2MPN2R2MG0L replace the L0806C2R2MDMIT in existing designs?

A: Yes. Both parts share identical inductance (2.2 µH), current rating (1.2 A), tolerance (±20%), package (0806 / 2016 Metric), and shielding characteristics. The substitute exhibits lower DC resistance (138mOhm vs. 140mOhm maximum) and an extended operating temperature range, making it functionally equivalent and suitable for direct substitution.

Q: What are the key differences between these two parts?

A: The primary differences are product status and operating temperature range. The L0806C2R2MDMIT is obsolete with an operating range of -40°C to 85°C, while the LQM2MPN2R2MG0L is active with an extended range of -55°C to 125°C. The substitute also features a slightly lower maximum DC resistance (138mOhm vs. 140mOhm).

Q: Are there any package or footprint differences?

A: No. Both parts use the identical 0806 (2016 Metric) surface mount package with dimensions of 0.079" L x 0.063" W (2.00mm x 1.60mm) and a maximum seated height of 0.039" (1.00mm). Direct board-level substitution is possible without layout changes.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the L0806C2R2MDMIT and LQM2MPN2R2MG0L are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring compliance continuity in regulated applications.

Q: What is the inductance tolerance for these parts?

A: Both parts carry a tolerance of ±20%, meaning the actual inductance value will fall within the range of 1.76 µH to 2.64 µH at the 1 MHz test frequency.

Q: Is the DC resistance specification critical for my application?

A: DC resistance affects power dissipation and thermal performance. The substitute's lower maximum DCR (138mOhm vs. 140mOhm) represents a marginal improvement. If your circuit design relies on the original 140mOhm specification as a maximum limit, the substitute will perform within or better than the original specification.

Q: Can I use the LQM2MPN2R2MG0L in applications requiring the original -40°C to 85°C temperature range?

A: Yes. The substitute's extended operating range of -55°C to 125°C fully encompasses the original specification, providing additional thermal margin. The part will operate reliably across the original temperature range and beyond.
