Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L0805R100MPWRT is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 10 µH
• Package / Case: 0805 (2012 Metric)
• DC Resistance (DCR): 360 mOhm
• Core type: Drum Core, Wirewound, Ferrite
• Shielding: Unshielded

Allowable Parameter Variations:

• Current Rating: Substitute must equal or exceed 125 mA
• Operating Temperature Range: Substitute must support the application's required temperature window
• Tolerance: ±20% is acceptable
• Self Resonant Frequency: 32 MHz

The LBR2012T100M from Taiyo Yuden qualifies as a direct substitute based on matching inductance, package, DCR, core type, and shielding specifications. The substitute provides an increased current rating of 150 mA, which exceeds the original 125 mA requirement.

Parameter Comparison

Engineering Selection Recommendations

The LBR2012T100M from Taiyo Yuden is electrically and mechanically compatible with the L0805R100MPWRT for applications operating within the -25°C to 105°C temperature range. Both components are RoHS3 compliant, REACH unaffected, and carry identical MSL ratings, ensuring equivalent environmental and regulatory compliance.

The primary consideration for substitution is the operating temperature lower limit. The original KEMET part operates to -40°C, while the Taiyo Yuden substitute operates to -25°C. Applications requiring operation below -25°C must retain the original specification or identify alternative sources.

The increased current rating of the LBR2012T100M (150 mA versus 125 mA) provides additional design margin and does not introduce compatibility issues. Both parts are classified as discontinued products, indicating limited future availability through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the LBR2012T100M directly replace the L0805R100MPWRT in existing designs?

A: The LBR2012T100M is a direct electrical and mechanical substitute for applications operating within -25°C to 105°C. The identical inductance, DCR, package dimensions, and electrical characteristics ensure pin-for-pin and footprint compatibility. The higher current rating does not create compatibility issues.

Q: What is the significance of the different operating temperature ranges?

A: The L0805R100MPWRT operates from -40°C to 105°C, while the LBR2012T100M operates from -25°C to 105°C. Applications requiring operation below -25°C must use the original KEMET part or identify alternative sources. Applications within the -25°C to 105°C window can use either part.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in the 0805 (2012 Metric) surface mount package with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.057", 1.45mm). The L0805R100MPWRT is supplied in Cut Tape (CT) packaging, while the LBR2012T100M is supplied in Tape & Reel (TR) packaging. Both packaging formats are compatible with standard pick-and-place assembly equipment.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the L0805R100MPWRT and LBR2012T100M are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. Both are classified under ECCN EAR99 and HTSUS 8504.50.8000.

Q: Why is the current rating higher on the substitute part?

A: The LBR2012T100M is rated for 150 mA continuous current compared to the 125 mA rating of the L0805R100MPWRT. This represents a design improvement by the manufacturer and does not affect substitution compatibility. The higher rating provides additional thermal margin in the application.

Q: What is the significance of the product status classifications?

A: The L0805R100MPWRT is classified as Obsolete, indicating it is no longer manufactured. The LBR2012T100M is classified as Not For New Designs, indicating limited availability and that new designs should identify alternative active parts. Both classifications indicate that long-term sourcing through standard distribution channels is constrained.
