armin 0 Report post Posted January 7, 2016 HelloIt is possible to replace 93LC46B serial eeprom with 93C46B (as i checked the difference is in supply voltage range, that is 2.5-5.5 volts for 93LC46B and 4.5-5.5 volts for 93C46B)? Share this post Link to post Share on other sites
Jack Gassett 0 Report post Posted January 7, 2016 Hello Armin, It looks like it should be fine, that chip is connected to the 5V power rail. Just be careful when bringing it up, feel for any warmth from the chip after you apply power. Jack. Share this post Link to post Share on other sites
