PS2801C-4-A Optoisolator 2500Vrms 4-Channel Transistor Output

Part Overview

The PS2801C-4-A is a 4-channel optoisolator with transistor output rated for 2500Vrms isolation voltage. This component provides galvanic isolation for control and signal circuits in industrial, automotive, and power management applications. The PS2801C-4-A has been discontinued at DiGi Electronics, making equivalent substitute parts essential for ongoing production and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PS2801C-4-A is determined by compatibility across the following critical electrical and mechanical parameters: 4-channel configuration, 2500Vrms minimum isolation voltage, transistor output type, 80V maximum output voltage, 30mA output current per channel, and 16-pin SOIC package with 4.40mm width.

Three direct equivalent parts are available from Renesas Electronics Corporation (the current manufacturer of the PS2801 series): PS2801C-4-F3-A, PS2801C-4-V-A, and PS2801C-4-V-F3-A. These parts maintain identical electrical specifications and package configuration. The primary differences are packaging format (Cut Tape & Digi-Reel versus Strip) and product status (all currently active).

The SFH6916 from Vishay Semiconductor represents a higher-performance alternative with enhanced isolation voltage (3750Vrms), faster switching characteristics, and higher output current capability (50mA versus 30mA). However, this part differs in output voltage maximum (70V versus 80V) and current transfer ratio range, making it suitable only for applications where these variations are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for Drop-In Replacement):

PS2801C-4-F3-A, PS2801C-4-V-A, and PS2801C-4-V-F3-A are all manufactured by Renesas Electronics Corporation and provide identical electrical performance and package compatibility with the discontinued PS2801C-4-A. All three substitute parts carry Active product status, ensuring long-term availability and continued manufacturer support. Selection among these three should be based on available packaging format and supplier inventory: PS2801C-4-F3-A and PS2801C-4-V-F3-A are supplied in Cut Tape & Digi-Reel format, while PS2801C-4-V-A is available in Strip format. All meet ROHS3 compliance and unlimited MSL requirements.

Alternative with Enhanced Performance:

The SFH6916 from Vishay Semiconductor offers higher isolation voltage (3750Vrms) and faster switching characteristics (5µs/4µs turn-on/turn-off versus 10µs/7µs). Output current capability is increased to 50mA per channel. However, output voltage maximum is reduced to 70V (versus 80V) and current transfer ratio maximum is 300% (versus 400%). This part is suitable only for applications where the reduced maximum output voltage is acceptable and the enhanced isolation and current capabilities provide benefit.

Frequently Asked Questions (FAQ)

Can PS2801C-4-F3-A, PS2801C-4-V-A, and PS2801C-4-V-F3-A be used interchangeably?

Yes. These three parts maintain identical electrical specifications, operating temperature range, isolation voltage, output characteristics, and 16-SOIC package configuration. The differences are limited to packaging format (Cut Tape & Digi-Reel versus Strip) and do not affect circuit-level performance or PCB footprint compatibility.

What are the primary differences between the Renesas PS2801C variants and the Vishay SFH6916?

The SFH6916 provides 3750Vrms isolation (1.5 times higher than 2500Vrms), reduced turn-on/turn-off times (5µs/4µs versus 10µs/7µs), and increased output current (50mA versus 30mA per channel). The SFH6916 has a maximum output voltage of 70V compared to 80V and a lower maximum current transfer ratio of 300% versus 400%. These differences require evaluation against specific application requirements before selection.

Is the SFH6916 a direct replacement for the PS2801C-4-A?

The SFH6916 is not a direct drop-in replacement due to differences in maximum output voltage and current transfer ratio range. It is suitable only for applications where these parameter variations are acceptable or beneficial. Circuit simulation or testing is required to confirm compatibility in the target application.

Are all substitute parts ROHS3 compliant?

Yes. All substitute parts—PS2801C-4-F3-A, PS2801C-4-V-A, PS2801C-4-V-F3-A, and SFH6916—are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), meeting current regulatory and reliability requirements.

What packaging formats are available for the Renesas PS2801C-4 variants?

PS2801C-4-F3-A and PS2801C-4-V-F3-A are supplied in Cut Tape (CT) & Digi-Reel format suitable for high-volume automated assembly. PS2801C-4-V-A is supplied in Strip format. All maintain identical 16-SOIC footprint dimensions (0.173" width, 4.40mm).

Does manufacturer change from CEL to Renesas Electronics affect design compatibility?

No. The PS2801C-4 series was acquired by Renesas Electronics Corporation. The substitute parts from Renesas maintain full electrical and mechanical compatibility with the original CEL design. No circuit modification or re-qualification is required for equivalent Renesas parts.
