Procurement Notes
Verify the specific revision level and screening requirements against MIL-PRF-19500 or MIL-STD-750 standards before procurement. Confirm availability as the part status may be listed as obsolete in some databases. Ensure compatibility with existing thermal management solutions given the wide operating temperature range.
Selection Notes
Select this component when high voltage isolation and extreme environmental tolerance are required. It is suitable for designs needing robust signal transmission in harsh conditions. Consider the axial package form factor during PCB layout planning. Verify that the transistor output configuration meets the interface requirements of the receiving circuitry.
Part Context
This device belongs to the Optek high-reliability optoelectronics line, which includes customizable commercial off-the-shelf (COTS) and MIL-spec products. The series is engineered for quality and performance in critical applications. The manufacturer supports these components with extensive technical expertise in high-reliability design.
Replacement Considerations
Check for direct substitutes such as the OPI120 or OPI123 if available. Verify pinout compatibility and electrical specifications before substitution. Note that the OPI120TX may have an obsolete status in certain channels, requiring careful evaluation of alternative sources.
