Substitute Part Grouping Explanation

Substitution of the ASPI-0840-2R0N is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2 µH (exact match required)
• Core type: Ferrite, shielded drum core, wirewound construction
• DC resistance: 12 mOhm (maximum specification)
• Package footprint: 8.00mm x 8.00mm surface mount
• Mounting type: Surface mount

Secondary Compatibility Factors:

• Current rating must meet or exceed the application requirement
• Saturation current must support the operating current envelope
• Operating temperature range must encompass the application environment
• Regulatory compliance (RoHS3, REACH status)

The ASPI-8040S-2R0N-T meets the primary matching criteria with identical inductance, core material, shielding, DC resistance specification, and package dimensions. However, the current rating differs, requiring application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-8040S-2R0N-T is an active production equivalent for the obsolete ASPI-0840-2R0N. Both components share identical inductance, DC resistance specification, core material, shielding architecture, and physical package dimensions.

Substitution Considerations:

The ASPI-8040S-2R0N-T has a reduced continuous current rating of 5.15 A compared to the original 6.8 A specification. This difference requires circuit-level evaluation to determine if the application current demand can be accommodated within the substitute part's rating. The substitute part provides higher saturation current (9.25 A versus 7 A), which may offer improved headroom in certain operating scenarios.

The substitute part operates across an extended temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), providing broader environmental compatibility. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The substitute part is in active production status with confirmed inventory availability, eliminating obsolescence risk associated with the original part.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-8040S-2R0N-T directly replace the ASPI-0840-2R0N in all applications?

A: Direct substitution is possible only when the application current requirement does not exceed 5.15 A continuous. The substitute part has a lower current rating (5.15 A versus 6.8 A). Applications operating at or below 5.15 A are compatible. Applications requiring the full 6.8 A rating require alternative solutions.

Q: Are the physical package dimensions identical?

A: Yes. Both components have identical surface mount package dimensions of 8.00mm x 8.00mm with a maximum seated height of 4.20mm. PCB footprints are interchangeable.

Q: What is the difference in saturation current between these parts?

A: The ASPI-0840-2R0N has a saturation current of 7 A, while the ASPI-8040S-2R0N-T has 9.25 A. The substitute part provides higher saturation margin, which may benefit applications with transient current spikes.

Q: Does the substitute part meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards.

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

A: The ASPI-8040S-2R0N-T operates from -40°C to 125°C, compared to -40°C to 85°C for the original part. This extended range provides compatibility with higher-temperature environments and thermal cycling scenarios.

Q: Are the DC resistance specifications equivalent?

A: Yes. Both components specify 12 mOhm DC resistance (the substitute lists this as maximum specification). DC resistance characteristics are equivalent for thermal and efficiency calculations.

Q: Why is the original part obsolete?

A: The ASPI-0840-2R0N is listed as obsolete by the manufacturer. The ASPI-8040S-2R0N-T represents the active production continuation with equivalent electrical and mechanical specifications.
