PS2811-1-F3 Equivalent & Substitute Parts

Part Overview

The PS2811-1-F3 is a 2500Vrms optoisolator with transistor output, single channel configuration in 4-SOIC surface mount package. Manufactured by CEL, this component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent and substitute parts from active manufacturers is necessary to maintain design continuity and ensure long-term component availability for new production runs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS2811-1-F3 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Voltage - Isolation: 2500Vrms (exact match required)
• Number of Channels: 1 (exact match required)
• Current Transfer Ratio range: 100% - 400% @ 1mA (exact match required)
• Output Type: Transistor (exact match required)
• Voltage - Output (Max): 40V (exact match required)
• Current - Output / Channel: 40mA (exact match required)
• Vce Saturation (Max): 300mV (exact match required)
• Operating Temperature Range: -55°C ~ 100°C (exact match required)
• Package / Case: 4-SOIC (0.173", 4.40mm Width) (exact match required)

Both identified substitute parts meet all critical electrical and mechanical parameters. The substitutes differ in product status (active vs. obsolete), packaging format (Strip vs. Tape & Reel), and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

PS2811-1-V-F3-A (Renesas Electronics Corporation) is the primary substitute for PS2811-1-F3. This part maintains active product status with Renesas Electronics Corporation, ensuring ongoing availability and technical support. The PS2811-1-V-F3-A is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Packaging in Tape & Reel format supports automated assembly processes. This part is functionally and electrically identical to the original PS2811-1-F3 across all critical parameters.

PS2811-1-V-A (Renesas Electronics Corporation) serves as a secondary substitute option. This part is also active status from Renesas Electronics Corporation with ROHS3 compliance and REACH unaffected status. The primary difference is packaging format (Strip vs. Tape & Reel), which may affect procurement and assembly workflow compatibility. Electrical and functional parameters are identical to PS2811-1-F3.

Both substitute parts from Renesas Electronics Corporation provide improved regulatory compliance compared to the obsolete CEL original, with ROHS3 certification and REACH unaffected status replacing the non-compliant and REACH-affected status of PS2811-1-F3.

Frequently Asked Questions (FAQ)

Q: Can PS2811-1-V-F3-A directly replace PS2811-1-F3 in existing designs?

A: Yes. PS2811-1-V-F3-A is electrically and mechanically identical to PS2811-1-F3. All critical parameters including isolation voltage (2500Vrms), current transfer ratio (100%-400% @ 1mA), output characteristics (40V max, 40mA per channel), and package dimensions (4-SOIC, 0.173" width) are identical. No circuit modifications are required.

Q: What is the difference between PS2811-1-V-A and PS2811-1-V-F3-A?

A: The primary difference is packaging format. PS2811-1-V-F3-A is supplied in Tape & Reel format, while PS2811-1-V-A is supplied in Strip format. All electrical parameters and package dimensions are identical. Selection depends on assembly process requirements and procurement specifications.

Q: Why is PS2811-1-F3 listed as obsolete?

A: PS2811-1-F3 is manufactured by CEL and carries obsolete product status. Renesas Electronics Corporation manufactures equivalent active alternatives (PS2811-1-V-A and PS2811-1-V-F3-A) that provide identical electrical performance with improved regulatory compliance.

Q: Are there compliance differences between the original and substitutes?

A: Yes. PS2811-1-F3 is RoHS non-compliant and REACH affected. Both Renesas substitutes (PS2811-1-V-A and PS2811-1-V-F3-A) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and production.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, for electrical function. All three parts use identical 4-SOIC package dimensions (0.173", 4.40mm width) and surface mount configuration. Packaging format differences (Strip vs. Tape & Reel) affect procurement and automated assembly handling, not PCB placement or electrical performance.

Q: What is the inventory status of substitute parts?

A: PS2811-1-V-F3-A has 7947 pieces in stock. PS2811-1-V-A has 2310 pieces in stock. Both are available from active inventory.
