Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2802-4-A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Channels: 4
• Voltage - Isolation: 2500Vrms
• Output Type: Darlington
• Current Transfer Ratio (Min): 200% @ 1mA
• Voltage - Output (Max): 40V
• Current - Output / Channel: 100mA
• Package / Case: 16-SOIC (0.173", 4.40mm Width)
• Operating Temperature Range: -55°C ~ 100°C

The identified substitute parts PS2802-4-A (Renesas Electronics Corporation) and PS2802-4-F3-A (Renesas Electronics Corporation) meet all mandatory electrical and mechanical parameters. Substitution is valid only when all parameters listed above are matched.

Parameter Comparison

Engineering Selection Recommendations

PS2802-4-F3-A (Renesas Electronics Corporation) is the primary substitute for the discontinued PS2802-4-A. This part maintains full electrical and mechanical equivalence while offering Active product status, ensuring continued availability and manufacturer support. The PS2802-4-F3-A is ROHS3 compliant and carries REACH Unaffected status, providing regulatory compliance for new designs and production applications.

PS2802-4-A (Renesas Electronics Corporation) serves as a secondary substitute option. This part is electrically and mechanically equivalent but carries Not For New Designs status, limiting its application to maintenance and legacy system support. It remains ROHS3 compliant and REACH Affected.

For new design implementations, PS2802-4-F3-A is the recommended selection based on Active product status and regulatory compliance. For existing systems requiring component replacement, both Renesas options provide full functional equivalence to the original CEL PS2802-4-A.

Frequently Asked Questions (FAQ)

Q: Can PS2802-4-F3-A directly replace PS2802-4-A in existing circuits?

A: Yes. PS2802-4-F3-A is electrically and mechanically equivalent across all specified parameters, including isolation voltage, channel count, output current, and package configuration. Direct substitution is valid without circuit modification.

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

A: Both parts are electrically identical. The primary difference is product status: PS2802-4-F3-A is Active, while PS2802-4-A (Renesas) is Not For New Designs. For new applications, PS2802-4-F3-A is preferred.

Q: Are there packaging differences between substitute options?

A: No. All three parts use identical 16-SOIC (0.173", 4.40mm Width) surface mount packaging. Footprint and land pattern compatibility is maintained across all substitutes.

Q: What compliance certifications apply to substitute parts?

A: PS2802-4-F3-A is ROHS3 compliant and REACH Unaffected. PS2802-4-A (Renesas) is ROHS3 compliant and REACH Affected. Both meet EAR99 export classification requirements.

Q: Is the 2500Vrms isolation rating maintained in substitute parts?

A: Yes. All substitute parts maintain 2500Vrms isolation voltage specification, ensuring equivalent galvanic isolation performance in high-voltage applications.

Q: Can substitutes handle the same output current per channel?

A: Yes. All substitute parts are rated for 100mA maximum output current per channel, matching the original PS2802-4-A specification.
