PS2533-1-V-A Optoisolator 5KV Darlington Output Equivalent & Substitute Parts

Part Overview

The PS2533-1-V-A is a high-voltage optoisolator with Darlington output, rated for 5000Vrms isolation voltage in a 4-DIP package. This component is designed for galvanic isolation applications requiring high voltage separation between input and output circuits with Darlington transistor switching capability. The PS2533-1-V-A is currently listed as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active inventory sources for continued system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS2533-1-V-A are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The allowable parameters for substitution are: isolation voltage rating (5000Vrms), single-channel configuration, Darlington output topology, current transfer ratio range (1500%-6500% @ 1mA), maximum output voltage (350V), output current capability (150mA), Vce saturation (1V maximum), operating temperature range (-55°C ~ 100°C), and 4-DIP package format with 0.300" (7.62mm) pitch.

All identified substitute parts maintain identical electrical performance characteristics and mechanical compatibility, differing only in manufacturer designation and product availability status.

Parameter Comparison

Engineering Selection Recommendations

For applications currently utilizing the PS2533-1-V-A (CEL), either Renesas Electronics Corporation substitute—PS2533-1-A or PS2533-1-V-A—represents a direct parametric equivalent with full electrical and mechanical interchangeability. Both Renesas alternatives are actively maintained products with established supply chains, offering enhanced long-term availability compared to the discontinued CEL variant.

From a compliance and certification perspective, both Renesas parts maintain ROHS3 compliance and REACH affection status consistent with the original design. Selection between the two Renesas options should be based on packaging availability (both are supplied in Tube format) and specific procurement channels; all three part numbers are members of the NEPOC series with identical base product designation (PS2533).

Frequently Asked Questions (FAQ)

Q: Can I directly substitute PS2533-1-A or PS2533-1-V-A (Renesas) for the discontinued PS2533-1-V-A (CEL)?

A: Yes. All three part numbers are parametrically identical across isolation voltage, output current, Darlington configuration, and package specifications. Direct pin-compatible substitution is supported without circuit modification.

Q: Are there any differences in the two Renesas alternatives, PS2533-1-A and PS2533-1-V-A?

A: Both Renesas variants are parametrically identical. They share the same electrical specifications, temperature range, and 4-DIP package. Selection should be based on inventory availability and packaging requirements (both are supplied in Tube format).

Q: What determines compatibility between the original and substitute parts?

A: Compatibility is determined by matching isolation voltage (5000Vrms), number of channels (1), output topology (Darlington), current transfer ratio range (1500%-6500% @ 1mA), maximum output voltage (350V), output current (150mA), package format (4-DIP, 0.300" pitch), and mounting type (Through Hole). All identified substitutes maintain these parameters.

Q: What are the inventory implications of these substitutes?

A: The original PS2533-1-V-A (CEL) has 9560 pieces in stock but is discontinued at DiGi Electronics. Both Renesas alternatives are active products: PS2533-1-A has 10667 pieces available, and PS2533-1-V-A (Renesas) maintains 9560 pieces in active inventory.

Q: Do these substitutes maintain compliance requirements?

A: Yes. All three parts are ROHS3 compliant and REACH affected, with identical Moisture Sensitivity Level (MSL 1 - Unlimited) ratings. No compliance degradation occurs with either substitute.
