Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS2801C-1-F3-M-A is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Channels: 1
• Voltage - Isolation: 2500Vrms
• Output Type: Transistor
• Package / Case: 4-SOIC (0.173", 4.40mm Width)
• Operating Temperature Range: -55°C ~ 100°C
• Input Type: DC

Allowable Parameter Variations:

• Current Transfer Ratio (Min): Substitute must meet or exceed 100% @ 5mA
• Current Transfer Ratio (Max): Must not exceed 400% @ 5mA
• Turn On / Turn Off Time: Must not exceed specified typical values
• Rise / Fall Time: Must not exceed specified typical values
• Voltage - Output (Max): Must be ≥ 80V
• Current - Output / Channel: Must be ≥ 30mA
• Vce Saturation (Max): Must not exceed 300mV

The PS2801C-1-A qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The PS2801C-1-A (Renesas Electronics Corporation) is electrically and mechanically compatible with the PS2801C-1-F3-M-A for direct substitution in existing circuit designs. Both components share identical isolation voltage, output characteristics, timing parameters, and package specifications.

Compliance Considerations:

• Both parts are ROHS3 compliant
• Both parts are REACH unaffected
• Both parts carry MSL rating of 1 (Unlimited)
• Both parts are classified under ECCN EAR99

Product Status Note: The PS2801C-1-A carries a "Not For New Designs" status from Renesas Electronics Corporation. The PS2801C-1-F3-M-A is discontinued at DiGi Electronics. For applications requiring active manufacturer support and ongoing availability, alternative optoisolator solutions outside the PS2801 series should be evaluated.

Current Transfer Ratio Variance: The PS2801C-1-A specifies a minimum current transfer ratio of 50% @ 5mA, compared to 100% @ 5mA for the main part. Circuit designs dependent on the higher minimum CTR specification of the PS2801C-1-F3-M-A require verification of performance margins with the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the PS2801C-1-A replace the PS2801C-1-F3-M-A in production?

A: Yes, the PS2801C-1-A is electrically and mechanically compatible. Both components feature identical isolation voltage (2500Vrms), output type (transistor), package configuration (4-SOIC), and operating temperature range (-55°C ~ 100°C). Pin-to-pin compatibility is confirmed.

Q: What is the difference in current transfer ratio between these parts?

A: The PS2801C-1-F3-M-A specifies a minimum CTR of 100% @ 5mA, while the PS2801C-1-A specifies 50% @ 5mA. Both share the same maximum CTR of 400% @ 5mA. Circuit designs must account for this variance in minimum performance.

Q: Are both parts RoHS compliant?

A: Yes, both the PS2801C-1-F3-M-A and PS2801C-1-A are ROHS3 compliant and REACH unaffected.

Q: What is the package compatibility?

A: Both parts use the 4-SOIC package with 0.173" width (4.40mm). PCB footprints and reflow profiles are identical.

Q: Why is the PS2801C-1-A marked "Not For New Designs"?

A: This designation indicates that Renesas Electronics Corporation is not recommending this part for new circuit designs. However, it remains available for replacement and maintenance of existing applications.

Q: Are there timing differences between these optoisolators?

A: No. Both parts specify identical turn-on/turn-off times (10µs, 7µs typical) and rise/fall times (5µs, 7µs typical).

Q: What is the maximum output current for both parts?

A: Both the PS2801C-1-F3-M-A and PS2801C-1-A support 30mA maximum output current per channel.
