PS2532L-1 Equivalent & Substitute Parts

Part Overview

The PS2532L-1 is an optoisolator with Darlington output featuring 5000Vrms isolation voltage and a single channel configuration in a 4-SMD, Gull Wing package. Manufactured by CEL, this component is marked as obsolete, necessitating identification of equivalent and substitute parts for continued design support and procurement. The PS2532L-1 specifications—particularly its 5000Vrms isolation rating, 150mA output current capability, and Darlington output configuration—define the parameters for identifying compatible alternatives.

Substitute Part Grouping Explanation

Substitute optoisolators for the PS2532L-1 must maintain electrical and mechanical compatibility across critical parameters. The substitution logic is based on the following requirements:

Electrical Compatibility:

• Isolation voltage: 5000Vrms (fixed requirement)
• Output type: Darlington configuration (fixed requirement)
• Single channel operation
• Output voltage rating: 300V minimum
• Output current capability: 150mA minimum

Mechanical Compatibility:

• Surface Mount technology
• 4-SMD, Gull Wing package format

Additional Considerations:

• Input type: DC
• Voltage-Forward (Vf) and Vce Saturation characteristics within acceptable range for switching applications
• Operating temperature range alignment

The LTV-852S manufactured by Lite-On Inc. qualifies as a direct substitute, meeting all electrical and mechanical requirements while offering improved performance specifications and active product status.

Engineering Selection Recommendations

Primary Substitute: LTV-852S

The LTV-852S is the qualified substitute for PS2532L-1 applications. This recommendation is based on:

1. Product Status: The LTV-852S holds active product status, ensuring ongoing availability and long-term supply chain support, contrasting with the obsolete PS2532L-1.

2. Compliance: LTV-852S is ROHS3 compliant, aligning with modern regulatory requirements for electronic components. The PS2532L-1 is RoHS non-compliant, limiting its applicability in new designs and restricted jurisdictions.

3. Electrical Equivalence: Both parts maintain identical isolation voltage (5000Vrms), output type (Darlington), maximum output voltage (300V), and output current (150mA). The LTV-852S offers higher maximum current transfer ratio (15000% vs. 6500%) and improved fall time performance (20µs vs. 100µs).

4. Mechanical Compatibility: Both components utilize identical 4-SMD, Gull Wing surface mount packages, enabling direct board-level substitution without layout modifications.

5. Operating Temperature: The LTV-852S supports -30°C to 100°C, covering typical industrial and commercial applications. For extended low-temperature operation below -30°C, the PS2532L-1 operating range extends to -55°C.

Frequently Asked Questions (FAQ)

Q: Can LTV-852S be directly substituted for PS2532L-1 in existing designs?

A: Yes. The LTV-852S maintains electrical equivalence across all critical parameters: 5000Vrms isolation, 150mA output current, 300V maximum output voltage, Darlington output configuration, and 4-SMD Gull Wing package. Direct board-level substitution is supported without schematic or layout modifications.

Q: What are the performance differences between PS2532L-1 and LTV-852S?

A: The LTV-852S exhibits superior switching characteristics with faster fall time (20µs vs. 100µs) and higher maximum current transfer ratio (15000% vs. 6500%), improving switching speed in high-frequency applications. Input forward current maximum is reduced to 50mA from 80mA, requiring circuit review for current-limited input designs.

Q: Is the operating temperature range difference significant?

A: The temperature range difference (-55°C to -30°C) affects only applications requiring extended cold-temperature operation. Most commercial and industrial applications operate within the -30°C to 100°C range supported by LTV-852S. Applications requiring -55°C minimum operating temperature must retain PS2532L-1 or identify alternative parts within that specification.

Q: Are RoHS compliance differences important?

A: LTV-852S ROHS3 compliance is essential for new product designs and sales into regulated jurisdictions. Existing designs using PS2532L-1 may continue operation, but new procurement should transition to RoHS-compliant alternatives. Verify regulatory requirements for your application and target markets.

Q: Are there other equivalent parts beyond LTV-852S?

A: The LTV-852S datasheet references additional substitutes including FOD852SD, FOD8523SD, FOD852S, IS852XSM, and FOD8523S. These parts share the same electrical specifications and package format. Detailed parameter comparison against specific application requirements is necessary for secondary substitute evaluation.

Q: What is the packaging format for procurement purposes?

A: PS2532L-1 packaging is not specified in available documentation. LTV-852S is supplied in Tube packaging. Confirm packaging format requirements with your supplier or design organization before procurement.
