Equivalent & Substitute Parts for EMD12T2R
Part Overview
The Rohm Semiconductor EMD12T2R is an active pre-biased bipolar transistor (BJT), featuring a dual (1 NPN, 1 PNP) configuration. It is supplied in a surface-mount SOT-563/SOT-666/EMT6 package and is compliant with RoHS3 and REACH standards. With key parameters including 50V collector-emitter breakdown voltage, 100mA collector current, and 150mW power dissipation, this component is widely used in compact electronic assemblies. Sourcing alternative models is necessary for supply chain flexibility, maintenance inventory, or when packaging and feature equivalency is essential for design interchangeability.

Substitute Part Grouping Explanation
Substitute parts for the EMD12T2R are identified based on equivalence of key parameters, specifically within the Transistors, Bipolar (BJT) category. The allowed electrical and mechanical parameter requirements for substitution include:
- Dual configuration: 1 NPN, 1 PNP - Pre-Biased (Dual)
- Maximum collector current: 100mA
- Maximum collector-emitter voltage: 50V
- Base and emitter resistor values: 47kOhms (R1, R2)
- Surface mount packages: SOT-563, SOT-666, or equivalent
- Compliance: RoHS3, REACH, MSL1
- Fully active product status
Parts not meeting any of these criteria are not included as substitutes. Only parameters provided in the input are considered.
