Description Of Change
Custom 6.4V zener diode from Microsemi will be replaced by an equivalent PCB assembly alternative device which utilizes ADI components, namely the
AD1580BKSZ and the ADR550BKSZ. Both the standard part and the alternative PCB device are surface mount components and have the same attachment
foot print. Resistor value changes to R22 (1B22) from 28K ohms to 24.3K ohms and R12 (1B41) from 15.4K ohms to 15.0K ohms are necessary to achieve
duplicate electrical performance.
Reason For Change
Increased raw material availability.
Anticipated impact of the change (positive or negative) on fit, form, function & reliability
There will be no change to the product fit, form, electrical performance or product reliability.
Product Identification (this section will describe how to identify the changed material)
Earliest possible date code is 0938.
Summary of Supporting Information
Representative samples from the 1B21 family will be used as the qualification vehicle per the attached qualification plan.
