Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-4020S-220M-T is determined by the following critical parameters:

Inductance value must match at 22 µH with ±20% tolerance specification. DC resistance must remain at 350mOhm to maintain circuit performance and thermal characteristics. Shielding type must be shielded to preserve electromagnetic isolation. Core material must be ferrite. Mounting type must be surface mount. Physical package dimensions must be 4.00mm x 4.00mm x 2.00mm maximum height. Operating temperature range must support the application's thermal requirements.

The BWVS00404018220M00 from Pulse Electronics qualifies as a direct substitute based on matching inductance, DC resistance, shielding, core material, mounting type, and package dimensions. The substitute part provides an elevated current rating of 850 mA, which exceeds the original specification and presents no compatibility constraint for applications designed around the 620 mA rating.

Parameter Comparison

Engineering Selection Recommendations

Both the ASPI-4020S-220M-T and BWVS00404018220M00 maintain active product status and full regulatory compliance under RoHS3 and REACH standards. The substitute part BWVS00404018220M00 provides equivalent electrical performance with identical inductance, tolerance, DC resistance, and shielding characteristics. The elevated current rating of 850 mA in the substitute part does not introduce compatibility issues for circuits designed to operate at or below 620 mA. The extended lower operating temperature limit of -55°C in the substitute part provides additional thermal margin for applications requiring extended cold-temperature operation. Both components are packaged identically and suitable for direct PCB footprint replacement.

Frequently Asked Questions (FAQ)

Q: Can BWVS00404018220M00 be used as a direct replacement for ASPI-4020S-220M-T?

A: Yes. Both parts share identical inductance (22 µH), DC resistance (350mOhm), shielding type (shielded), core material (ferrite), mounting type (surface mount), and package dimensions (4.00mm x 4.00mm x 2.00mm). The substitute part is electrically and mechanically compatible.

Q: Does the higher current rating of the substitute part affect circuit operation?

A: No. The BWVS00404018220M00 current rating of 850 mA exceeds the original 620 mA specification. Applications designed for 620 mA operation will function identically with the higher-rated substitute part.

Q: Are there temperature range differences between the two parts?

A: The substitute part BWVS00404018220M00 operates from -55°C to 125°C, compared to the original part's -40°C to 125°C range. This provides extended cold-temperature capability without affecting standard operating conditions.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both ASPI-4020S-220M-T and BWVS00404018220M00 are ROHS3 compliant, REACH unaffected, and classified under identical ECCN and HTSUS codes.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package dimensions and mounting type enable direct footprint compatibility and interchangeable assembly processes.
