Key Parameters

Substitute Part Grouping Explanation

Substitution for the PS2833-4-A is determined by strict equivalence across the following critical parameters:

• Number of Channels: 4
• Voltage - Isolation: 2500Vrms
• Current Transfer Ratio: 400% (Min) @ 1mA and 4500% (Max) @ 1mA
• Output Type: Darlington
• Voltage - Output (Max): 350V
• Current - Output / Channel: 60mA
• Vce Saturation (Max): 1V
• Operating Temperature Range: -55°C ~ 100°C
• Package / Case: 16-SOIC (0.173", 4.40mm Width)
• Input Type: DC

The PS2833-4-V-A meets all these parameters and is therefore a direct parametric equivalent. Both parts share the same base product number (PS2833) and are manufactured by Renesas Electronics Corporation.

Parameter Comparison

Engineering Selection Recommendations

The PS2833-4-V-A is a direct parametric substitute for the PS2833-4-A. All electrical and mechanical specifications are identical. The primary distinction is product lifecycle status: the PS2833-4-A is designated "Not For New Designs," while the PS2833-4-V-A carries "Active" status, indicating ongoing manufacturer support and availability.

From a compliance perspective, both parts are ROHS3 compliant. The PS2833-4-V-A has REACH Unaffected status, whereas the PS2833-4-A is REACH Affected. This difference may be relevant for applications subject to REACH regulatory requirements.

For applications currently using the PS2833-4-A, the PS2833-4-V-A provides functional continuity with the added benefit of active product status and improved regulatory positioning.

Frequently Asked Questions (FAQ)

Q: Can the PS2833-4-V-A be used as a direct replacement for the PS2833-4-A?
