Transistor, Photovoltaic Output Optoisolators Procurement Notes

This component is officially listed as obsolete and no longer manufactured by the producer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or third-party suppliers. Buyers must confirm the specific manufacturing date code and ensure the parts have not exceeded storage life limits, as availability is limited to existing inventory rather than new production runs.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Engineers should evaluate alternative components due to the discontinued status of this part. When selecting a replacement, verify that the substitute maintains equivalent isolation voltage ratings and channel count. Ensure the new component fits the required SMD-8 footprint if board space is constrained. Check for compatibility in current transfer ratio and saturation voltage to maintain circuit performance without redesigning the isolation barrier.
