PS2505L-4-A Optoisolator: Equivalent & Substitute Parts

Part Overview

The PS2505L-4-A is a 4-channel optoisolator with transistor output designed for galvanic isolation applications requiring 5000Vrms isolation voltage. The device features AC/DC input capability with transistor output configuration in a 16-SMD package. The main part (CEL manufacturer) is discontinued at DiGi Electronics, necessitating identification of equivalent substitutes from alternative manufacturers for continued supply and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PS2505L-4-A is based on matching the following critical electrical and mechanical parameters:

• Isolation Voltage: 5000Vrms (defines primary isolation capability)
• Channel Configuration: 4 channels (functional architecture requirement)
• Output Type: Transistor (functional interface requirement)
• Current Transfer Ratio Range: 80% (min) to 600% (max) @ 5mA (signal transmission efficiency)
• Maximum Output Voltage: 80V (output voltage capability)
• Output Current per Channel: 50mA (load driving capability)
• Package / Case: 16-SMD, Gull Wing (physical form factor)
• Operating Temperature: -55°C ~ 100°C (thermal operating envelope)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Parts meeting all these parameters are considered direct parametric equivalents capable of pin-to-pin and functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The PS2505L-4-A from Renesas Electronics Corporation is a parametric equivalent to the discontinued CEL variant. Both devices satisfy identical electrical specifications and mechanical packaging requirements.

For new designs, note that the Renesas variant carries a "Not For New Designs" status, indicating limited long-term availability. Component selection should account for supply continuity and lifecycle planning. Both variants comply with ROHS3 and REACH requirements, supporting applications requiring regulatory compliance.

Inventory availability differs between sources: the CEL variant shows 1022 units in stock, while the Renesas variant shows 8332 units. Supply chain considerations may influence selection between available inventory positions.

Frequently Asked Questions (FAQ)

Q: Are the PS2505L-4-A parts from CEL and Renesas Electronics fully interchangeable? A: Yes. The devices are identical in all specified electrical parameters, channel count, isolation voltage, output characteristics, operating temperature range, and package configuration. Pin-to-pin and functional replacement is supported without circuit modification.

Q: What determines whether a component can substitute for the PS2505L-4-A? A: Substitution requires matching on: 4-channel configuration, 5000Vrms isolation voltage, 80-600% current transfer ratio, transistor output type, 80V maximum output voltage, 50mA per-channel output current, 16-SMD gull wing package, -55°C to 100°C temperature range, and ROHS3 compliance status.

Q: What is the significance of the "Not For New Designs" status on the Renesas variant? A: This designation indicates the manufacturer is not recommending the part for new designs due to long-term lifecycle or availability considerations. The device continues to function identically to specification but may face future supply constraints. Applications should plan accordingly for component sourcing and potential future platform migrations.

Q: Does packaging type affect compatibility between variants? A: The CEL variant packaging type is unspecified, while the Renesas variant is supplied in tube packaging. Both conform to the 16-SMD gull wing package specification. Tube packaging indicates the quantity and form of incoming components but does not affect electrical or mechanical compatibility for board assembly.

Q: Are both variants compliant with regulatory requirements? A: Yes. Both the CEL and Renesas variants are ROHS3 compliant and REACH affected, supporting applications requiring compliance with these regulatory frameworks.
