Frequently Asked Questions (FAQ)

Q: Why is the SWF2L23APYGI8 no longer available? A: The SWF2L23APYGI8 has reached obsolete product status. Microchip Technology has transitioned support to the ATM90E26-YU-R, which provides equivalent energy meter functionality with active manufacturing and supply chain support.

Q: Is the ATM90E26-YU-R a direct pin-for-pin replacement? A: Both devices use SSOP packaging. The ATM90E26-YU-R is specified as a 28-SSOP package. Verify pinout compatibility with your specific application requirements and PCB layout before implementation.

Q: What are the key differences between these parts? A: The ATM90E26-YU-R provides specified operating temperature range (-40°C ~ 85°C), supply voltage (2.8 V ~ 3.6 V), measurement error (0.5%), and input impedance parameters. The original SWF2L23APYGI8 does not have these parameters documented. The ATM90E26-YU-R also features improved moisture sensitivity (MSL 2 vs. MSL 3).

Q: Are both parts RoHS compliant? A: Yes, both the SWF2L23APYGI8 and ATM90E26-YU-R are ROHS3 compliant, meeting restricted substance requirements for regulated applications.

Q: What is the moisture sensitivity difference? A: The SWF2L23APYGI8 has MSL 3 (168 hours), while the ATM90E26-YU-R has MSL 2 (1 year). MSL 2 indicates improved moisture tolerance and longer shelf life under standard storage conditions.

Q: Can I use the ATM90E26-YU-R in existing designs? A: The ATM90E26-YU-R is the manufacturer-recommended substitute. Verify package dimensions, pinout, and electrical specifications against your PCB design and application requirements before implementation.
