Frequently Asked Questions (FAQ)

Q: Why is the SWF2L23APYGI no longer available? A: The SWF2L23APYGI has reached obsolete status. The ATM90E26-YU-B is the active replacement designated by Microchip Technology for new designs and ongoing procurement.

Q: Are the SWF2L23APYGI and ATM90E26-YU-B pin-compatible? A: Both devices use SSOP packaging. The ATM90E26-YU-B is specified as 28-SSOP. Detailed pinout verification is required during design integration to confirm compatibility with existing PCB layouts.

Q: What are the key differences in specifications? A: The ATM90E26-YU-B provides documented specifications including single-phase meter functionality, operating temperature range (-40°C ~ 85°C), supply voltage (2.8 V ~ 3.6 V), and measurement error (0.5%). The original part specifications were not fully documented in available data.

Q: Does the substitute meet the same compliance requirements? A: Both devices are ROHS3 compliant. The ATM90E26-YU-B has improved moisture sensitivity (MSL 2 versus MSL 3), providing better handling and storage characteristics.

Q: What is the recommended approach for design migration? A: Verify pinout compatibility, confirm voltage supply requirements align with system design, and validate measurement accuracy specifications for the target application. Consult Microchip Technology datasheets for complete technical specifications.
