PS2806-1-F3 Equivalent & Substitute Parts

Part Overview

The PS2806-1-F3 is a single-channel optoisolator with Darlington output, rated for 2500Vrms isolation voltage. This component is classified as Obsolete, indicating it is no longer in active production. The NEPOC series optoisolator is designed for applications requiring high-voltage isolation between input and output circuits with AC or DC input capability.

Due to its obsolete status, identifying functionally equivalent substitute parts is necessary for ongoing system maintenance, repair, and new design considerations where legacy compatibility is required.

Substitute Part Grouping Explanation

Substitution of the PS2806-1-F3 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage - Isolation: 2500Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Darlington (mandatory match)
• Current Transfer Ratio (Min): 200% @ 1mA (mandatory match)
• Voltage - Output (Max): 40V (mandatory match)
• Current - Output / Channel: 90mA (mandatory match)
• Input Type: AC, DC (mandatory match)
• Operating Temperature Range: -55°C ~ 100°C (mandatory match)

Mechanical Equivalence Requirements:

• Mounting Type: Surface Mount (mandatory match)
• Package / Case: 4-SOIC form factor with 0.173" (4.40mm) width (mandatory match)

The PS2806-1-F3-A qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Maintenance: The PS2806-1-F3-A is electrically and mechanically equivalent to the PS2806-1-F3 across all specified parameters. Both components share identical isolation voltage, channel configuration, output characteristics, and thermal operating range. The substitute part maintains full functional compatibility for repair and replacement applications in existing systems.

Compliance Considerations: The PS2806-1-F3-A offers improved regulatory compliance compared to the main part. It is ROHS3 compliant and REACH unaffected, whereas the PS2806-1-F3 is RoHS non-compliant and REACH affected. For applications subject to environmental or regulatory restrictions, the PS2806-1-F3-A is the preferred choice.

Product Status: The PS2806-1-F3 is classified as Obsolete. The PS2806-1-F3-A is classified as Not For New Designs. Both statuses indicate limited availability and production support. Component selection should prioritize current-generation alternatives for new system designs.

Frequently Asked Questions (FAQ)

Q: Can PS2806-1-F3-A directly replace PS2806-1-F3 in existing circuits?

A: Yes. The PS2806-1-F3-A is electrically and mechanically equivalent. All critical parameters including isolation voltage (2500Vrms), output current (90mA), Darlington output configuration, and package form factor (4-SOIC) are identical. No circuit modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are manufacturer (CEL vs. Renesas Electronics Corporation), product status (Obsolete vs. Not For New Designs), and regulatory compliance. The PS2806-1-F3-A offers ROHS3 compliance and REACH compliance, while the PS2806-1-F3 does not.

Q: Are there package differences between these parts?

A: Both parts use the 4-SOIC package with 0.173" (4.40mm) width. The supplier device package designation differs (4-SOP vs. 4-SSOP), but the physical form factor and pin configuration are compatible for PCB mounting.

Q: Which part should be selected for new designs?

A: Neither part is recommended for new designs. The PS2806-1-F3 is Obsolete, and the PS2806-1-F3-A is Not For New Designs. Current-generation optoisolator alternatives should be evaluated for new system development.

Q: What is the current transfer ratio specification?

A: Both parts specify a minimum current transfer ratio of 200% at 1mA input current. This parameter defines the ratio of output current to input current and is critical for circuit design calculations.

Q: Are there thermal or operating temperature limitations?

A: Both parts operate across the identical temperature range of -55°C to 100°C. No thermal derating or operational differences exist between the two components within this range.
