Procurement Notes
Verify component availability through authorized distributors, noting that this part is designated as not recommended for new designs. Confirm datasheet revisions and RoHS compliance status prior to integration. Ensure storage conditions meet specified moisture sensitivity levels to maintain reliability during assembly processes.
Selection Notes
Select this component for existing designs requiring a 25V NPN RF transistor in a UMT3 package. Evaluate thermal management requirements against the 200mW power dissipation limit. Consider the 300MHz frequency constraint for target application bandwidths before finalizing the bill of materials.
Part Context
This transistor belongs to Rohm Semiconductor's discrete bipolar product line, specifically categorized under RF transistors. The UMT3 packaging provides a small footprint suitable for space-constrained portable electronics. As a legacy component, it serves established hardware architectures rather than modern greenfield developments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the 'not recommended for new design' status, alternative components should be sourced based on specific electrical parameter matching and package compatibility.
