Sumitomo Electric Industries JA761783 Board

Sumitomo Electric Industries JA761783CC and JA761784CX are circuit board units from Sumitomo’s JA761 family, described in listings as PCB Circuit Board components with AP-M and AP-IP variant designations. The part numbers appear alongside related JA761-series identifiers such as JA761070HC and JA761070GC, indicating a family of boards with multiple revisions or configurations used in Sumitomo equipment. These boards are commonly found on third‑party marketplaces and refurbish listings, labeled as Sumitomo circuit boards (AP-M and AP-IP variants) and offered as standalone PCBs for service or repair. Because exact revision details and variant compatibility can vary, buyers should confirm the specific JA761783CC or JA761784CX configuration and its AP-M or AP-IP designation with the seller prior to purchase.
