507-4757-3331-500F is a red LED indicator lamp cartridge designed for 5 VDC operation. The device features a cylindrical plastic lens with an internal Fresnel ring pattern to maximize light output, housed in an aluminum body with a 0.90-inch overall length. The lamp incorporates a 0.040-inch diameter pin and operates with critical polarity requirements; the rated voltage must not be exceeded by more than 5% to avoid damage. This RoHS-compliant component is compatible with Dialight 250 and 508 series holders for 0.375-inch mounting holes or 515 series connectors for 9/32-inch mounting holes, making it suitable for industrial control panels, instrumentation displays, and status indication applications.
