Substitute Part Grouping Explanation

Substitution of the MPIA4040R3-150-R is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Inductance value: 15 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Shielding classification: Shielded
• Mounting type: Surface Mount
• AEC-Q200 qualification: Required

Secondary Compatibility Parameters:

• Current rating must equal or exceed 1.3 A continuous
• Saturation current (Isat) must equal or exceed 3 A
• DC resistance must not exceed 285 mOhm
• Operating temperature range must encompass -55°C to 125°C
• Moisture sensitivity level: 1 (Unlimited)

The substitute part B82464G4153M000 meets all primary equivalence criteria and exceeds secondary compatibility thresholds, making it a valid functional replacement.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The B82464G4153M000 is a valid functional substitute for the MPIA4040R3-150-R based on electrical parameter equivalence. Both components share identical inductance values, tolerance specifications, shielding classification, and AEC-Q200 qualification status.

Advantages of B82464G4153M000:

• Active product status ensures long-term availability and supply chain continuity
• Superior current rating (2.75 A vs. 1.3 A) provides design margin
• Lower DC resistance (40 mOhm vs. 285 mOhm) reduces power dissipation
• Extended operating temperature range (-55°C to 150°C vs. -55°C to 125°C)
• ROHS3 compliance and REACH unaffected status meet modern regulatory requirements
• Ferrite core technology with wirewound construction offers established manufacturing reliability

Design Considerations:

Physical dimensions differ significantly. The B82464G4153M000 occupies a larger PCB footprint (10.40mm x 10.40mm vs. 4.45mm x 4.06mm) and greater height (4.80mm vs. 1.80mm). PCB layout verification is required to confirm spatial compatibility within the target application.

Core material differs (ferrite vs. metal composite), resulting in different electromagnetic characteristics. Both components meet the specified inductance and tolerance requirements at 100 kHz test frequency. Frequency response behavior may differ outside the test frequency; circuit performance validation is appropriate for frequency-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can B82464G4153M000 directly replace MPIA4040R3-150-R without circuit modification?

A: Electrical substitution is valid. Both components deliver 15 µH inductance at ±20% tolerance with identical shielding and AEC-Q200 qualification. Physical footprint differences require PCB layout verification. No circuit schematic changes are necessary if spatial constraints are satisfied.

Q: Why is the DC resistance of B82464G4153M000 significantly lower (40 mOhm vs. 285 mOhm)?

A: The difference reflects distinct core materials and construction methods. B82464G4153M000 uses ferrite core with wirewound construction, while MPIA4040R3-150-R employs metal composite molded technology. Lower DCR reduces resistive losses and heat generation, which is advantageous for power efficiency.

Q: Does the larger physical size of B82464G4153M000 affect electrical performance?

A: Physical dimensions do not alter the electrical specifications provided. Size differences result from different manufacturing processes and core geometries. Electrical performance is determined by inductance value, tolerance, current rating, and frequency response—all of which are equivalent or superior in the substitute part.

Q: Is B82464G4153M000 suitable for high-frequency applications?

A: B82464G4153M000 specifies a self-resonant frequency of 15 MHz. Applications operating significantly below this frequency will experience stable inductance behavior. Frequency response characteristics differ from the original part due to core material differences; circuit validation is appropriate for frequency-dependent designs.

Q: What is the impact of the extended temperature range of B82464G4153M000?

A: B82464G4153M000 operates from -55°C to 150°C, exceeding the original specification of -55°C to 125°C. This provides additional thermal margin for applications approaching the upper temperature limit. No negative impact occurs; the extended range represents enhanced capability.

Q: Are there packaging differences between these parts?

A: B82464G4153M000 is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly. MPIA4040R3-150-R packaging details are not specified. TR packaging is compatible with automated pick-and-place equipment and is the industry standard for SMD components.

Q: Does ROHS3 compliance of B82464G4153M000 affect compatibility?

A: ROHS3 compliance is a regulatory advantage with no negative electrical impact. If the target application or end market requires ROHS compliance, B82464G4153M000 satisfies this requirement while MPIA4040R3-150-R status is unspecified. This is a benefit for modern design requirements.
