Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0805C150MPWST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 15 µH
• Inductance tolerance: ±20%
• Package format: 0805 (2012 Metric)
• Core material and type: Ferrite, drum core, wirewound
• Shielding configuration: Unshielded
• Operating temperature range: -40°C to 105°C
• DC resistance: 1.3 Ohm (nominal or maximum specification)
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Current rating may exceed the original specification, provided the substitute part maintains all other electrical and mechanical parameters
• Physical dimensions may vary within the 0805 package envelope
• Self-resonant frequency may differ while maintaining functional performance at the specified inductance frequency test point of 2.52 MHz

Parameter Comparison

Engineering Selection Recommendations

The BRL2012T150M manufactured by Taiyo Yuden is a direct functional equivalent to the L0805C150MPWST. Both components share identical inductance values, tolerance specifications, DC resistance characteristics, package dimensions, and operating temperature ranges. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity ratings.

The BRL2012T150M provides a higher current rating of 300 mA compared to the original 100 mA specification, which represents an enhancement in current-handling capability without degradation of other electrical parameters. The reduced seated height of 0.039" (1.00mm) versus 0.057" (1.45mm) on the original part may provide board layout advantages in space-constrained applications.

Both the original part and its substitute are classified as obsolete or not recommended for new designs. Selection between these parts should be based on current inventory availability and application requirements. The Taiyo Yuden BRL2012T150M offers superior current capacity for applications requiring headroom beyond the original 100 mA specification.

Frequently Asked Questions (FAQ)

Q: Can the BRL2012T150M be used as a direct replacement for the L0805C150MPWST in existing designs?

A: Yes. Both components share identical inductance values (15 µH), tolerance specifications (±20%), DC resistance (1.3 Ohm), package format (0805/2012 Metric), and operating temperature ranges (-40°C to 105°C). The substitute part is electrically and mechanically compatible for direct board-level substitution.

Q: What is the significance of the higher current rating on the BRL2012T150M?

A: The BRL2012T150M is rated for 300 mA continuous current, compared to 100 mA on the L0805C150MPWST. This higher rating does not affect compatibility; it indicates the substitute part can safely handle greater current loads without saturation or thermal degradation. Applications operating at or below 100 mA experience no change in performance.

Q: Are there dimensional differences between these parts?

A: Both parts conform to the 0805 (2012 Metric) package standard with identical length and width dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). The seated height differs: the original part measures 0.057" (1.45mm) maximum, while the substitute measures 0.039" (1.00mm) maximum. This reduced height may provide board layout benefits in applications with vertical space constraints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the L0805C150MPWST and BRL2012T150M are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). Both parts are classified under ECCN EAR99 and HTSUS code 8504.50.8000.

Q: What is the difference between "Obsolete" and "Not For New Designs" product status?

A: The L0805C150MPWST is classified as obsolete, indicating the manufacturer has discontinued production and support. The BRL2012T150M is classified as "Not For New Designs," indicating the manufacturer still maintains limited inventory but does not recommend this part for new product development. For new applications, consultation with component suppliers regarding current availability and long-term sourcing is necessary.

Q: Are the self-resonant frequencies equivalent?

A: The L0805C150MPWST specifies a self-resonant frequency of 28 MHz, while the BRL2012T150M specifies 15 MHz. Both parts are tested and specified at the same inductance frequency test point of 2.52 MHz. The difference in self-resonant frequency does not affect substitution compatibility for applications operating within the specified frequency range.
