Key Parameters

Substitute Part Grouping Explanation

Substitution of the SWPA6045S680MT is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 68 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Shielding type: Shielded construction
• Core material: Ferrite
• Mounting type: Surface Mount
• Physical footprint: 6.00 mm × 6.00 mm base dimensions

Secondary Compatibility Parameters:

• Current rating: Minimum 900 mA (substitute may have lower rating than primary part)
• DC resistance: Maximum 330 mOhm (substitute may have lower DCR)
• Saturation current: Minimum 1.2 A
• Operating temperature range: Minimum -40°C to 125°C coverage
• Inductance test frequency: 100 kHz

The BWVS00606045680M00 qualifies as a substitute because it maintains the core inductance specification, shielding, ferrite core material, surface mount configuration, and identical base footprint. Variations in current rating, DCR, and package case designation do not preclude substitution when the application current requirement does not exceed the substitute part's rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (SWPA6045S680MT): Select the SWPA6045S680MT when the application requires the full 1 A current rating and the primary sourcing channel is available. This part is active in production with adequate inventory (5200 units in stock).

Substitute Part Selection (BWVS00606045680M00): The BWVS00606045680M00 is suitable as a substitute when:

• The application current requirement does not exceed 900 mA
• The circuit design can accommodate the 0.20 mm additional height (4.70 mm vs. 4.50 mm seated height)
• Extended low-temperature operation to -55°C is beneficial or required
• The lower DC resistance (330 mOhm vs. 376 mOhm) is acceptable or advantageous for the application

Both parts maintain identical inductance, tolerance, shielding, core material, footprint, and test frequency specifications. The BWVS00606045680M00 carries ROHS3 compliance documentation, which may be required for certain applications or markets. Both parts are active in production and available in tape and reel packaging.

Frequently Asked Questions (FAQ)

Q: Can the BWVS00606045680M00 be used as a direct replacement for the SWPA6045S680MT in all applications?

A: The BWVS00606045680M00 is a functional substitute provided the application current does not exceed 900 mA. The primary difference is the current rating: the substitute is rated 100 mA lower than the original part. If your circuit draws more than 900 mA through the inductor, the substitute part is not appropriate. All other electrical parameters (inductance, tolerance, DCR, saturation current) and mechanical parameters (footprint, height, shielding) are compatible.

Q: What is the impact of the 0.20 mm height difference between these parts?

A: The BWVS00606045680M00 has a maximum seated height of 4.70 mm compared to 4.50 mm for the SWPA6045S680MT. This 0.20 mm difference must be evaluated against your PCB layout clearances, enclosure height constraints, and any automated assembly equipment specifications. If your design has tight vertical clearance, this difference may be significant.

Q: Are there any compliance or certification differences between these parts?

A: The BWVS00606045680M00 is documented as ROHS3 Compliant and REACH Unaffected. The SWPA6045S680MT specifications do not include explicit RoHS or REACH documentation in the provided data. Both parts carry EAR99 ECCN classification and identical HTSUS codes. If your application requires documented RoHS3 compliance, the BWVS00606045680M00 provides this certification.

Q: How do the DC resistance values affect circuit performance?

A: The BWVS00606045680M00 has a DC resistance of 330 mOhm compared to 376 mOhm maximum for the SWPA6045S680MT. Lower DC resistance results in reduced resistive losses and lower heat generation at the same current level. This difference is approximately 12% lower resistance in the substitute part. For applications sensitive to inductor losses, the lower DCR of the substitute may be advantageous.

Q: What is the significance of the saturation current difference?

A: The BWVS00606045680M00 has a saturation current of 1.44 A compared to 1.2 A for the SWPA6045S680MT. Saturation current represents the point at which the inductor's inductance begins to degrade due to core saturation. The substitute part has a higher saturation margin, which provides additional headroom before inductance degradation occurs. This is a favorable characteristic for the substitute part.

Q: Can I use the SWPA6045S680MT in applications requiring the extended temperature range of the BWVS00606045680M00?

A: The SWPA6045S680MT operates from -40°C to 125°C, while the BWVS00606045680M00 operates from -55°C to 125°C. If your application requires operation below -40°C, the SWPA6045S680MT is not suitable. The substitute part's extended low-temperature range (-55°C) makes it the appropriate choice for such applications.

Q: Are both parts available in the same packaging format?

A: Yes, both the SWPA6045S680MT and BWVS00606045680M00 are supplied in Tape & Reel (TR) packaging, which is standard for automated PCB assembly. The packaging format is identical, so no changes to your assembly process are required from a tape and reel perspective.

Q: What does the ±20% inductance tolerance mean for circuit design?

A: The ±20% tolerance means the actual inductance value can vary from 54.4 µH to 81.6 µH across the manufacturing range. Both the primary part and substitute maintain this identical tolerance specification. Circuit designs using these inductors must account for this tolerance range in filter calculations, impedance matching, or any frequency-dependent applications.
