Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SWPA6045S220MT are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 22 µH (±20% tolerance band)
• Inductance test frequency: 100 kHz
• Core material: Ferrite
• Shielding: Shielded construction
• Mounting type: Surface Mount
• Physical footprint: 6.00 mm x 6.00 mm base dimensions

Secondary Compatibility Parameters:

• Current rating: Minimum 1.8 A continuous
• Saturation current (Isat): Minimum 2.2 A
• DC resistance: Within acceptable operating limits for thermal and efficiency considerations

Engineering Selection Recommendations

BWVS00606045220M00 (Pulse Electronics) - Primary Substitute

This part is the preferred substitute for the SWPA6045S220MT. The BWVS00606045220M00 provides a current rating of 1.9 A, which exceeds the original specification of 1.8 A. The DC resistance of 125 mOhm is within acceptable operating parameters compared to the 116 mOhm maximum of the original part. The saturation current of 3.0 A provides additional margin above the 2.2 A specification. Operating temperature range extends to -55°C, providing enhanced low-temperature performance. The part maintains Active product status with 4246 units in stock and carries RoHS3 compliance and REACH Unaffected status.

BWVC00606045220M00 (Pulse Electronics) - Secondary Substitute

This part serves as an alternative substitute with a current rating of 1.71 A, which is slightly below the original 1.8 A specification. The DC resistance of 130 mOhm is marginally higher than the original 116 mOhm maximum. The saturation current of 2.97 A provides adequate margin. Operating temperature range extends to -55°C. The part maintains Active product status with 3007 units in stock and carries RoHS3 compliance and REACH Unaffected status. Selection of this part requires confirmation that the 1.71 A rating is sufficient for the application circuit.

Both substitute parts share identical inductance values, tolerance bands, core materials, shielding characteristics, and surface mount configuration as the original SWPA6045S220MT. Physical footprints are identical at 6.00 mm x 6.00 mm, with maximum seated heights of 4.70 mm compared to 4.50 mm for the original part.

Frequently Asked Questions (FAQ)

Q: Can BWVS00606045220M00 or BWVC00606045220M00 be used as direct replacements for SWPA6045S220MT in existing designs?

A: Both Pulse Electronics parts are electrically and mechanically compatible substitutes. The identical 22 µH inductance value, ±20% tolerance, ferrite core construction, shielded design, and 6.00 mm x 6.00 mm footprint enable direct PCB placement. The maximum seated height increases from 4.50 mm to 4.70 mm; verify clearance in the application enclosure. BWVS00606045220M00 is preferred due to its 1.9 A current rating, which exceeds the original 1.8 A specification.

Q: What is the impact of the higher DC resistance in the substitute parts?

A: The BWVS00606045220M00 has 125 mOhm DCR compared to 116 mOhm maximum for the original part, representing a 7.8% increase. The BWVC00606045220M00 has 130 mOhm DCR, representing a 12.1% increase. Higher DC resistance results in increased resistive losses and heat generation at rated current. For applications operating continuously at 1.8 A, thermal performance should be evaluated. The substitute parts' higher saturation currents (3.0 A and 2.97 A respectively) provide additional design margin.

Q: Are the substitute parts RoHS and REACH compliant?

A: Both BWVS00606045220M00 and BWVC00606045220M00 carry RoHS3 compliance and REACH Unaffected status. The original SWPA6045S220MT does not specify RoHS or REACH compliance in the provided data. If regulatory compliance is a requirement, the Pulse Electronics substitutes satisfy these certifications.

Q: What is the significance of the extended operating temperature range in the substitute parts?

A: The substitute parts operate from -55°C to 125°C, compared to -40°C to 125°C for the original part. The extended lower temperature limit provides an additional 15°C of cold-temperature performance margin. This is beneficial for applications requiring operation in harsh environmental conditions or high-altitude deployments where ambient temperatures may drop below -40°C.

Q: How do the saturation current specifications compare?

A: The original SWPA6045S220MT has an Isat of 2.2 A. The BWVS00606045220M00 provides 3.0 A Isat, and the BWVC00606045220M00 provides 2.97 A Isat. Both substitutes offer significantly higher saturation margins, reducing the risk of core saturation in transient current conditions or design margin erosion over component lifetime.

Q: Are there any package or footprint differences that affect assembly?

A: The original part uses a Nonstandard package designation, while BWVC00606045220M00 uses 2424 (6060 Metric) package designation and BWVS00606045220M00 uses Nonstandard designation. Despite different package nomenclature, all three parts share identical 6.00 mm x 6.00 mm base dimensions and surface mount configuration. The maximum seated height increases from 4.50 mm to 4.70 mm for both substitutes; verify clearance in the application design.

Q: What inventory considerations apply to these substitutes?

A: The original SWPA6045S220MT has 2190 units in stock. BWVS00606045220M00 has 4246 units available, and BWVC00606045220M00 has 3007 units available. Both substitutes offer superior inventory availability, supporting supply chain continuity and production scheduling.
