PS2533L-1-A Optoisolator - Equivalent & Substitute Parts

Part Overview

The PS2533L-1-A is a high-voltage optoisolator with Darlington output, rated for 5000Vrms isolation voltage, single channel configuration, and 4-SMD surface mount packaging. This component is designed for galvanic isolation applications requiring robust performance across industrial temperature ranges (-55°C to 100°C). The original PS2533L-1-A manufactured by CEL is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active inventory sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2533L-1-A is determined by matching the following critical electrical and mechanical parameters:

Electrical Parameters (Must Match Exactly):

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Darlington
• Current Transfer Ratio Range: 1500% - 6500% @ 1mA
• Voltage - Output (Max): 350V
• Current - Output / Channel: 150mA
• Vce Saturation (Max): 1V
• Operating Temperature Range: -55°C ~ 100°C

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Supplier Device Package: 4-SMD

The substitute parts PS2533L-1-F3-A and PS2533L-1-V-F3-A are classified as direct manufacturer substitutes, manufactured by Renesas Electronics Corporation with identical electrical and mechanical specifications. The parametric equivalents PS2533L-1-A and PS2533L-1-V-A, also from Renesas Electronics Corporation, are electrically and mechanically equivalent but differ in packaging format (Tube versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

For applications where the discontinued PS2533L-1-A (CEL) must be replaced, the following selection criteria apply based on product status and regulatory compliance:

Active Product Direct Substitutes (Recommended):

• PS2533L-1-F3-A: Available in Tape & Reel packaging, 25400 units in stock, REACH Unaffected status, ROHS3 compliant, active product status.
• PS2533L-1-V-F3-A: Available in Tape & Reel packaging, 5300 units in stock, REACH Unaffected status, ROHS3 compliant, active product status.

Active Product Parametric Equivalents (Alternative Packaging):

• PS2533L-1-A (Renesas): Available in Tube packaging, 2798 units in stock, REACH Affected status, ROHS3 compliant, active product status.
• PS2533L-1-V-A (Renesas): Available in Tube packaging, 2999 units in stock, REACH Affected status, ROHS3 compliant, active product status.

All substitute parts maintain identical electrical specifications and 4-SMD Gull Wing package geometry. Selection between direct substitutes and parametric equivalents depends on procurement quantity requirements and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PS2533L-1-F3-A and PS2533L-1-V-F3-A be used interchangeably with the original PS2533L-1-A?

A: Both PS2533L-1-F3-A and PS2533L-1-V-F3-A are direct manufacturer substitutes manufactured by Renesas Electronics Corporation with identical electrical and mechanical specifications. Both are manufactured under the same NEPOC series and meet all electrical parameter requirements of the original part.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment, while Tube packaging is suitable for manual or semi-automated assembly. Both formats contain the same component with identical electrical and mechanical properties. Selection depends on assembly process requirements.

Q: Are all substitutes ROHS3 compliant?

A: All listed parts are ROHS3 compliant. However, REACH compliance status differs. The direct substitutes (PS2533L-1-F3-A and PS2533L-1-V-F3-A) are REACH Unaffected, while the parametric equivalents in Tube packaging are REACH Affected.

Q: What happens if I run out of the specified inventory quantities?

A: All substitute parts listed are active products with confirmed inventory. The part with the highest inventory availability is PS2533L-1-F3-A with 25400 units in stock.

Q: Can I mix packaging formats in the same procurement?

A: Electrical and mechanical substitution is valid across all packaging formats (Tape & Reel versus Tube). Procurement decisions depend on assembly line compatibility and quantity requirements.

Q: What are the isolation voltage and output current specifications?

A: All parts in this substitution group support 5000Vrms isolation voltage and 150mA maximum output current per channel, with identical Darlington output configuration.
