개요

Description

I can’t identify B0503S-2WR3 uniquely without more context. There are multiple devices with similar codes (relays, sensors, modules) from different manufacturers.
Could you share:
- the manufacturer or a datasheet link, or
- what kind of device it is (relay, sensor, module, etc.)?

Pinout

B0503S-2WR3 is a 4‑pin isolated DC‑DC converter (SIP‑4). Pin functions:
- Pin 1: +Vin (input +)
- Pin 2: −Vin (input − / return)
- Pin 3: +Vout (output +)
- Pin 4: −Vout (output − / isolated return)
(Always confirm exact pin numbering and footprint in the manufacturer’s datasheet.)

Equivalent

I don’t have the part’s manufacturer or datasheet. Please confirm or share a link. B0503S-2WR3 is likely a 5V‑in, 3V‑out, ~2W isolated DC‑DC module; equivalents would be 5V→3V isolated 2W converters from Traco, RECOM, Murata or TDK—but exact pinout, dimensions, and specifications must match. Provide the datasheet or maker and I’ll list exact drop‑in equivalents.
