PS2805C-1-A Equivalent & Substitute Parts

Part Overview

The PS2805C-1-A is an optoisolator with transistor output designed for high-voltage isolation applications. It provides 2500Vrms isolation rating in a compact 4-SOIC surface mount package and is capable of supporting both AC and DC input signals with a maximum output current of 30mA per channel.

The original PS2805C-1-A manufactured by CEL is currently discontinued at DiGi Electronics. Due to this discontinuation, equivalent parts from Renesas Electronics Corporation offer viable alternatives that maintain identical electrical and mechanical specifications, ensuring seamless integration into existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the PS2805C-1-A optoisolator is determined by strict electrical and mechanical parameter matching across the following critical specifications:

• Voltage isolation rating (2500Vrms minimum)
• Current transfer ratio operating range (50% to 400% @ 5mA)
• Output characteristics (transistor type, 80V maximum, 30mA per channel)
• Timing parameters (turn-on/off and rise/fall times)
• Thermal operating range (-55°C to 100°C)
• Physical form factor (4-SOIC package, 0.173" width, 4.40mm width standard)
• Compliance certifications (ROHS3, REACH Unaffected)

All substitute parts listed maintain these parameters without deviation. Substitutes are grouped into two categories: Similar Manufacturer Parts (alternative packaging or supplier configurations of the same electrical device) and Parametric Equivalents (identical electrical specifications with potential status or series variations).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PS2805C-1-V-A

The PS2805C-1-V-A is the optimal substitute for the discontinued PS2805C-1-A. This part is manufactured by Renesas Electronics Corporation with an Active product status, ensuring long-term availability and ongoing manufacturer support. It maintains complete electrical and mechanical specification parity with the original component and carries full ROHS3 compliance and REACH Unaffected certification. Strip packaging is suitable for standard production integration.

Secondary Recommendation: PS2805C-1-F3-A

The PS2805C-1-F3-A offers an alternative with identical electrical specifications and Active product status. It is available in Cut Tape and Digi-Reel packaging formats, providing flexibility for both high-volume and low-volume procurement scenarios. This variant is particularly advantageous for automated assembly processes requiring tape-and-reel formats.

Alternative Consideration: PS2805C-1-V-F3-A

The PS2805C-1-V-F3-A maintains complete parameter equivalence and Active status but may have limited availability (4445 units in stock). It serves as a viable substitute when PS2805C-1-V-A stock levels are insufficient.

Not Recommended for New Designs: PS2805C-1-A (Renesas)

The Renesas-manufactured PS2805C-1-A carries a "Not For New Designs" status and should not be selected for new development efforts, despite electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the discontinued CEL PS2805C-1-A with a Renesas PS2805C-1-V-A?

A: Yes. All electrical parameters, timing specifications, and physical package dimensions are identical. The parts are pin-compatible and functionally equivalent in the 4-SOIC form factor.

Q: What is the difference between PS2805C-1-F3-A and PS2805C-1-V-A?

A: The electrical and mechanical specifications are identical. The primary difference is packaging: PS2805C-1-F3-A is supplied in Cut Tape and Digi-Reel format, while PS2805C-1-V-A is supplied in Strip format. Select based on your assembly equipment compatibility and procurement volume requirements.

Q: Why is PS2805C-1-A (Renesas) marked "Not For New Designs"?

A: This designation indicates the manufacturer has phased this specific variant in favor of actively supported alternatives. While it remains electrically equivalent, PS2805C-1-V-A or PS2805C-1-F3-A are preferred for new designs to ensure manufacturer support continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 Compliant status and REACH Unaffected certification, meeting current environmental and regulatory requirements.

Q: Will these substitutes work in applications requiring -55°C to 100°C operation?

A: Yes. All substitute parts are rated for the full -55°C to 100°C operating temperature range specified for the original PS2805C-1-A.

Q: What are the isolation voltage capabilities of these substitutes?

A: All substitute parts provide 2500Vrms isolation voltage, matching the original specification. This rating applies uniformly across all listed alternatives.
