Substitute Part Grouping Explanation

Substitute parts for the PS2802-4 are identified based on exact electrical and mechanical equivalence across the following critical parameters:

• Isolation Voltage: 2500Vrms (mandatory match)
• Channel Configuration: 4 channels (mandatory match)
• Output Architecture: Darlington output type (mandatory match)
• Package Form Factor: 16-SOIC with 0.173" (4.40mm) width (mandatory match)
• Current Transfer Ratio: 200% minimum @ 1mA (mandatory match)
• Output Voltage & Current Ratings: 40V max, 100mA per channel (mandatory match)
• Operating Temperature Range: -55°C ~ 100°C (mandatory match)

All substitute parts listed maintain these electrical and mechanical specifications, ensuring direct replacement capability in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

PS2802-4-F3-A (Renesas Electronics Corporation) is the primary recommended substitute for new designs and obsolescence management. This part maintains full electrical and mechanical equivalence while offering:

• Active product status with manufacturer support
• ROHS3 compliance certification
• Digi-Reel® packaging option for automated assembly processes

PS2802-4-A (Renesas Electronics Corporation) serves as an alternative substitute with identical electrical specifications and ROHS3 compliance. Its "Not For New Designs" status indicates continued availability for replacement in existing systems but makes it less suitable for new product development.

Both Renesas alternatives provide equivalent functionality for the 2500Vrms isolation, 4-channel Darlington output architecture specified in the original PS2802-4.

Frequently Asked Questions (FAQ)

Q: Can PS2802-4-F3-A and PS2802-4-A be used interchangeably with the original PS2802-4?

A: Yes. All three parts share identical electrical parameters including isolation voltage (2500Vrms), channel count (4), output type (Darlington), current transfer ratio (200% @ 1mA), voltage/current ratings, and operating temperature range. The 16-SOIC package geometry is consistent across all variants.

Q: What is the difference between PS2802-4-A and PS2802-4-F3-A?

A: Both maintain equivalent electrical specifications. The primary differences are product status (PS2802-4-F3-A is Active vs. PS2802-4-A is Not For New Designs) and packaging options (PS2802-4-F3-A offers Cut Tape and Digi-Reel®, while PS2802-4-A is supplied in Strip packaging).

Q: Does the substitute part support the same isolation voltage?

A: Yes. Both PS2802-4-A and PS2802-4-F3-A maintain the 2500Vrms isolation rating required by the original PS2802-4 specification.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both PS2802-4-A and PS2802-4-F3-A are ROHS3 compliant, providing improved environmental compliance compared to the original non-compliant part.

Q: Can these parts be used in surface-mount assembly?

A: Yes. All parts use the 16-SOIC surface-mount package and are suitable for automated PCB assembly processes. Packaging options vary between reel, strip, and cut tape formats for different procurement and assembly workflows.
