PS2501L-1-L-A Equivalent & Substitute Parts

Part Overview

The PS2501L-1-L-A is a single-channel optoisolator with transistor output, rated for 5000Vrms isolation voltage. This component is designed for applications requiring galvanic isolation between input and output circuits in surface mount configurations. The main part (CEL manufacturer) is discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives to maintain supply chain continuity and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2501L-1-L-A is determined by strict equivalence across the following critical parameters:

Isolation and Electrical Performance:

• Voltage isolation rating: 5000Vrms
• Current transfer ratio range: 200% to 400% @ 5mA
• Output voltage maximum: 80V
• Output current per channel: 50mA
• Vce saturation: 300mV maximum

Physical and Functional Characteristics:

• Single channel configuration
• Transistor output type
• DC input type
• Rise/fall time: 3µs and 5µs

Package and Environmental:

• 4-SMD, Gull Wing package
• Surface mount mounting type
• Operating temperature range: -55°C to 100°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS3 compliance
• REACH affected status

A substitute part must match all parameters listed above. Variations in manufacturer, product status, or packaging format (tube vs. other) do not affect functional equivalence when all electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

The PS2501L-1-L-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL version. Both parts are identical across all electrical specifications, mechanical dimensions, and environmental ratings.

Selection Basis:

The Renesas Electronics version is recommended for new procurement due to active product status and confirmed inventory availability (11,401 pieces in stock). The CEL version is no longer available through DiGi Electronics distribution channels.

Both versions maintain ROHS3 compliance and REACH affected status, ensuring regulatory alignment for applications subject to these requirements. The Moisture Sensitivity Level 1 (Unlimited) classification indicates no special handling requirements during storage or assembly.

The 4-SMD, Gull Wing package format is consistent between both manufacturers, permitting direct board-level substitution without PCB redesign or assembly process modification.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS2501L-1-L-A replace the discontinued CEL version in existing designs?

A: Yes. All electrical parameters, mechanical dimensions, and environmental specifications are identical. Direct substitution is supported without circuit modification or board redesign.

Q: What are the critical parameters that define substitution compatibility for this optoisolator?

A: Substitution compatibility is determined by: isolation voltage (5000Vrms), current transfer ratio range (200-400% @ 5mA), output voltage maximum (80V), output current (50mA), Vce saturation (300mV), package type (4-SMD Gull Wing), and operating temperature range (-55°C to 100°C).

Q: Does packaging format affect substitution eligibility?

A: Packaging format (tube, tape and reel, or other) does not affect electrical or mechanical compatibility. The component specifications remain identical regardless of packaging method. Verify packaging availability with your supplier based on procurement requirements.

Q: Are there any compliance or regulatory differences between the two manufacturers?

A: No. Both versions are ROHS3 compliant, REACH affected, and classified under ECCN EAR99. Regulatory status is equivalent.

Q: What is the Moisture Sensitivity Level (MSL) significance for this part?

A: MSL 1 (Unlimited) indicates this component has no moisture sensitivity restrictions. Standard storage and handling procedures are sufficient; no special dry-pack or bake-out procedures are required prior to assembly.

Q: Can this optoisolator be used in high-temperature applications?

A: The operating temperature range is -55°C to 100°C. Applications requiring operation above 100°C require alternative component selection outside this specification range.
