PS2505L-1-F3-A Equivalent & Substitute Parts

Part Overview

The PS2505L-1-F3-A is an optoisolator with transistor output, rated for 5000Vrms isolation voltage, featuring 1 channel in a 4-SMD surface mount package. The main part is discontinued at DiGi Electronics, necessitating evaluation of substitute optoisolators that meet the core electrical and mechanical specifications. Suitable alternatives must maintain the 5000Vrms isolation rating, transistor output configuration, and 4-SMD gull wing package format while accommodating differences in performance parameters within acceptable application ranges.

Substitute Part Grouping Explanation

Substitution relationships are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Lite-On LTV-814 Series): The LTV-814HS and LTV-814HS-TA1 are functionally equivalent substitutes for the PS2505L-1-F3-A. Both parts share the following critical parameters: 5000Vrms isolation voltage, 1-channel transistor output configuration, 4-SMD gull wing surface mount package, AC/DC input capability, and ROHS3 compliance with MSL 1. These parts differ in packaging format (Tube versus Tape & Reel) but are electrically compatible. Electrical performance differs in output voltage handling (35V maximum versus 80V), output current (80mA versus 50mA), current transfer ratio specifications, and forward voltage characteristics. These differences are within typical design margins for optoisolator applications.

Parametric Equivalent (Renesas PS2505L-1-F3-A): The Renesas Electronics Corporation part numbered PS2505L-1-F3-A shares identical electrical specifications with the main part, providing exact parametric equivalence with differences limited to packaging format (Cut Tape & Digi-Reel versus original format) and product status (Not For New Designs).

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The LTV-814HS and LTV-814HS-TA1 optoisolators are recommended for new applications requiring 5000Vrms isolation and transistor output. Both Lite-On parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity rating, supporting long-term supply chain continuity.

For Parametric Equivalence: The Renesas Electronics PS2505L-1-F3-A provides exact electrical parameter matching with the original CEL part but carries a "Not For New Designs" status. This part is suitable only for legacy design maintenance or direct replacement in existing production runs where precise electrical specifications are critical.

For Packaging Flexibility: LTV-814HS is supplied in Tube packaging, while LTV-814HS-TA1 is supplied in Tape & Reel format. Selection depends on assembly requirements and volume considerations.

Parameter Trade-offs: Lite-On LTV-814 substitutes operate within a reduced temperature range (-30°C to 100°C versus -55°C to 100°C) and provide different output voltage/current specifications. Applications requiring the full -55°C temperature range or 80V output voltage must select parts supporting these parameters.

Frequently Asked Questions (FAQ)

Q: Can the LTV-814HS be used as a direct replacement for the PS2505L-1-F3-A in all applications?

A: The LTV-814HS shares the core isolation rating (5000Vrms), package format (4-SMD gull wing), and output type (transistor). It is electrically compatible for most standard isolation applications. However, applications requiring maximum output voltage (80V) or extended low-temperature operation (-55°C) must be evaluated against the LTV-814HS specifications (35V maximum output voltage, -30°C minimum operating temperature).

Q: What is the difference between LTV-814HS and LTV-814HS-TA1?

A: Both parts are electrically identical with equivalent performance specifications. The distinction is packaging format: LTV-814HS is supplied in Tube packaging, while LTV-814HS-TA1 is supplied in Tape & Reel format. Selection depends on your assembly process and volume requirements. Tape & Reel packaging is typical for high-volume automated assembly.

Q: Why is the PS2505L-1-F3-A (Renesas) listed as "Not For New Designs"?

A: The Renesas PS2505L-1-F3-A maintains identical electrical specifications to the original CEL part but carries a product lifecycle designation limiting it to legacy applications. This status indicates the manufacturer is not recommending this part for new design introductions. Active alternatives such as the Lite-On LTV-814 series are preferred for new projects.

Q: Are all parts ROHS3 compliant and MSL 1 rated?

A: Yes, all four parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, confirming compatibility with standard PCB assembly and storage practices.

Q: What parameters are critical for substitution compatibility?

A: Substitution compatibility is determined by isolation voltage (5000Vrms), channel count (1), output type (transistor), package format (4-SMD gull wing), and mounting type (surface mount). Applications must also confirm that output voltage requirements (35V or 80V maximum), output current needs (50mA or 80mA), and operating temperature range (-30°C or -55°C minimum) are satisfied by the selected substitute part.
