...daca sunt compatibile pin la pin, eu am inlocuit de multle ori cu ld7535....., saptamana trecuta am gasit  intr-o sursa (incarcator acumulator boxa portabila) un controler marcat asemanator, l-am identificat dupa pini si l-am inlocuit cu ld7535. A functionat perfect ! 

Este capsula cu 6 pini ?

Multumesc pt. raspuns ! E capsula cu 6 pini.Rusul mai spune ceva : LD 7535 are intern la iesirea GATE pt. mosfet o reziztenta la masa , aceasta lipseste la LN3C63.Pe placa la care lucrez rez. e montata extern intre GATE si GND. La inlocuirea pe care ai facut-o ai scos rez de pe PCB , cum recomanda rusul ? Mi-ai dat o idee : prin incarcatoare de telefon s-ar putea sa gasesc originalul....Mersi !
