Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SWPA8040S150MT are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 15 µH (±20% tolerance)
• Inductance test frequency: 100 kHz
• Core material: Ferrite
• Mounting type: Surface Mount
• Package dimensions: 8.00 x 8.00 mm footprint with 4.20 mm maximum seated height
• Packaging format: Tape & Reel
• Operating temperature range: Minimum -40°C to 125°C coverage

Secondary Compatibility Parameters:

• DC resistance within acceptable limits for the application
• Current rating and saturation current sufficient for circuit requirements
• Shielding configuration (shielded or semi-shielded acceptable for EMI-sensitive applications)

The substitute parts BWVS00808040150M00 and SDCH1V8040-150M-R meet these criteria with variations in current handling capability and DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

BWVS00808040150M00 (Pulse Electronics): This substitute provides improved current handling capability at 3.2 A compared to the main part's 2.6 A rating, with lower DC resistance of 50 mOhm. The extended operating temperature range (-55°C to 125°C) offers broader environmental coverage. RoHS3 compliance and REACH unaffected status confirm regulatory alignment. This part is suitable for applications requiring higher current capacity or lower resistive losses within the same physical footprint.

SDCH1V8040-150M-R (Eaton - Electronics Division): This substitute maintains current rating at 2.8 A with DC resistance of 58 mOhm, closely matching the main part's electrical characteristics. The semi-shielded configuration differs from the fully shielded design of the main part. Operating temperature range matches the main part at -40°C to 125°C. RoHS3 compliance and REACH unaffected status confirm regulatory alignment. This part is suitable for applications where semi-shielded performance is acceptable and cost optimization is a consideration.

All three parts share identical inductance values, tolerance specifications, package dimensions, and mounting characteristics, confirming mechanical and electrical interchangeability within the defined parameter space.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SWPA8040S150MT?

A: Substitution is determined by matching inductance value (15 µH at ±20% tolerance), inductance test frequency (100 kHz), core material (ferrite), surface mount configuration, package footprint (8.00 x 8.00 mm), seated height (4.20 mm maximum), and operating temperature range coverage (-40°C to 125°C minimum). DC resistance and current ratings must be compatible with circuit requirements.

Q: Can the BWVS00808040150M00 replace the SWPA8040S150MT in all applications?

A: The BWVS00808040150M00 is electrically and mechanically compatible. It provides higher current rating (3.2 A versus 2.6 A) and lower DC resistance (50 mOhm versus 61 mOhm maximum). The extended temperature range (-55°C to 125°C) provides additional environmental coverage. Substitution is valid for applications operating within the SWPA8040S150MT's original specifications.

Q: What is the difference between shielded and semi-shielded configurations?

A: The SWPA8040S150MT and BWVS00808040150M00 feature full shielding, while the SDCH1V8040-150M-R is semi-shielded. Shielding reduces electromagnetic interference (EMI) radiation and susceptibility. Semi-shielded designs provide partial EMI containment. Selection depends on application EMI requirements and board layout constraints.

Q: Are all three parts RoHS compliant?

A: The BWVS00808040150M00 and SDCH1V8040-150M-R explicitly state RoHS3 compliance. The SWPA8040S150MT does not specify RoHS status in the provided data. Verify RoHS compliance requirements with the component supplier for the main part if regulatory compliance is mandatory.

Q: Do these parts have identical physical dimensions?

A: Yes. All three parts share identical package dimensions of 8.00 x 8.00 mm footprint with 4.20 mm maximum seated height. They are pin-compatible and require no PCB layout modifications for substitution.

Q: What is the significance of saturation current (Isat) values?

A: Saturation current indicates the current level at which the inductor's inductance begins to degrade due to core saturation. The SWPA8040S150MT has Isat of 3.4 A, BWVS00808040150M00 has 3.6 A, and SDCH1V8040-150M-R has 3.2 A. Circuit design must ensure operating current remains below these thresholds to maintain specified inductance performance.

Q: Can I use the SDCH1V8040-150M-R if my application requires full shielding?

A: The SDCH1V8040-150M-R is semi-shielded, not fully shielded. If full shielding is required for EMI control, use the SWPA8040S150MT or BWVS00808040150M00. Semi-shielded performance may be insufficient for noise-sensitive applications.

Q: What does ±20% inductance tolerance mean?

A: All three parts have ±20% inductance tolerance at 100 kHz test frequency. This means the actual inductance value can range from 12 µH to 18 µH. Circuit design must account for this tolerance range to ensure proper operation across production variations.
