Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2832-4 is determined by the following critical electrical and mechanical parameters:

• 4-channel configuration with Darlington output topology
• 2500Vrms isolation voltage rating
• Current transfer ratio range of 400% minimum to 4500% maximum at 1mA input
• 60mA output current per channel capability
• 1V maximum Vce saturation in conducting state
• 16-SOIC package with 0.173" width (4.40mm)
• Surface mount technology compatibility

The PS2833-4-V-A qualifies as a direct substitute based on matching all critical electrical parameters and package specifications. The substitute maintains identical isolation voltage, channel count, current transfer ratio range, output current rating, and saturation characteristics. The physical package dimensions and mounting type remain identical, enabling direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The PS2833-4-V-A from Renesas Electronics Corporation is the primary active substitute for the obsolete PS2832-4. Both components share identical electrical characteristics and package specifications, ensuring functional and physical compatibility for direct replacement applications.

The PS2833-4-V-A offers enhanced product status advantages: the component maintains active manufacturing status with current inventory availability. The substitute achieves improved regulatory compliance through ROHS3 certification and REACH unaffected status, compared to the PS2832-4's non-compliant and REACH affected classification. The PS2833-4-V-A also provides a higher maximum output voltage rating of 350V versus the PS2832-4's 300V rating, delivering greater design margin in isolation stage applications.

Selection of the PS2833-4-V-A eliminates obsolescence risk and supports long-term supply chain stability while maintaining electrical and mechanical interchangeability with legacy PS2832-4 designs.
