Procurement Notes

Verify the complete part number including the ordering suffix TE85L,F to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Validate that the SMV-5 footprint matches the target PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required for space-constrained designs. The 22 kΩ input resistance suits standard logic interface levels. Ensure the 50 V voltage rating and 100 mA current capacity meet the specific load requirements of the target application circuit.

Part Context

This component belongs to Toshiba's RN series of bias resistor built-in transistors. These devices are engineered to simplify circuit design by replacing discrete transistors and resistors with single packaged units. The RN1503 specifically provides a dual NPN solution suitable for general-purpose digital switching tasks.

Replacement Considerations

Cross-reference with other dual NPN digital transistors in the SMV-5 package having similar VCEO, IC, and R1 values. Verify pinout compatibility and thermal characteristics before substitution.
