pentru jrc4558 cred ca poti folosi MC4558; UPC4558; TS4558; CJ4558; TS4558; NJM4558; SL4558D; IL4558D; RC4558 si cam atat ca-mi e prea lene sa mai dau copy/paste.

Intra pe http://www.alldatasheet.com si cauta datasheet-ul pentru circuitul tau (sau in alta parte), afla ce e si ce face (din cate am inteles la ora asta "matinala" e un am operational dual) apoi da search cu included in care scrii doar cifrele din denumirea integratului. O sa iti apara o lista de vre-o 4-5 pagini cu diverse componente. Te uiti la descrierea lor si vezi ce ti se potriveste, tragi datasheet-ul si compari.

 

Scuze daca jrc-ul tau nu era un AO dual, retine principiul de cautare al echivalentelor pt integrate :yawinkle:

 

un exemplu de echivalent pt celalalt circuit..UPC3403C (Ground Sensing Quad Operational Amplifier sau HIGH PERFORMANCE QUAD OPERATIONAL AMPLIFIER); MC3403D

 

Spor la explorat!
