Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Toshiba Semiconductor and Storage. Procurement must rely on available substitute parts or existing stock from authorized distributors. Verify compatibility with the BF888H6327XTSA1 if replacement is required. Ensure all sourcing channels confirm the obsolete status before initiating any purchase orders to avoid fulfillment issues.

Selection Notes

Select this part only for legacy designs requiring specific VHF/UHF low noise amplifier characteristics. Due to its obsolete status, new designs should consider alternative components with similar electrical profiles. Evaluate the available substitute options carefully to ensure they meet the original circuit requirements for noise figure and gain at operating frequencies.

Part Context

The 2SC5086 series belongs to Toshiba's lineup of silicon NPN epitaxial planar transistors intended for radio frequency applications. This specific variant targets low noise amplification in very high and ultra-high frequency ranges. The product line includes related models such as the 2SC5086-Y, which shares similar application domains but may differ in specific electrical parameters or packaging configurations.

Replacement Considerations

Public confirmed substitutes include the BF888H6327XTSA1 from Infineon Technologies. Verify that the substitute meets the required voltage, frequency, and noise specifications for the specific application.
