Anachip AP3843 versus Fairchild Semiconductor UC3843B:
Archived third-party cross-reference table with no publication date. Historical device-family research candidate, not a complete ordering code or verified drop-in equivalent. Match package, pinout, voltage/current ratings, output variant, timing, control polarity, thermal limits and current manufacturer datasheets before substitution. Reverse lookup does not establish reverse replacement suitability. Only the printed Anachip-to-competitor relation is recorded; no equivalence between competitor columns is inferred. Source section: Linear & switching regulator; row 10.
