PS2815-1-L-A Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2815-1-L-A is a 2500Vrms optoisolator with transistor output in a 4-SOIC package, manufactured by CEL. This component provides galvanic isolation for single-channel signal transmission with AC/DC input compatibility. The part is currently discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives. Substitute parts are available from Renesas Electronics Corporation with identical electrical specifications and package configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2815-1-L-A is based on strict electrical and mechanical equivalence across the following key parameters:

• Isolation Voltage: 2500Vrms (mandatory equivalence)
• Number of Channels: 1 channel configuration
• Current Transfer Ratio Range: 100% to 400% @ 1mA
• Output Type: Transistor output configuration
• Maximum Output Voltage: 40V
• Maximum Output Current: 40mA per channel
• Package Type: 4-SOIC surface mount (0.173", 4.40mm width)
• Rise / Fall Time Specification: 4µs, 5µs
• Operating Temperature Range: -55°C ~ 100°C
• Voltage Forward (Vf): 1.15V (typical)
• Vce Saturation: 300mV (maximum)

All identified substitute parts maintain identical electrical characteristics and identical physical packaging. The primary variation among substitutes is packaging format (Strip, Cut Tape & Digi-Reel, Tape & Reel, Tube) and manufacturer assignment (all are Renesas Electronics Corporation variants or manufacturer reassignments). Substitutes also differ in inventory availability and product status designations.

Engineering Selection Recommendations

For New Designs: Select PS2815-1-F3-A or PS2815-1-V-F3-A. Both parts maintain Active product status and are approved for new design implementations. PS2815-1-F3-A is available in Cut Tape & Digi-Reel format with 2178 units in stock. PS2815-1-V-F3-A is available in Tape & Reel format with 4351 units in stock and offers the highest inventory availability among active alternatives.

For Existing Design Continuation: PS2815-1-A and PS2815-1-V-A are functional substitutes with identical electrical parameters. PS2815-1-A carries a "Not For New Designs" designation but remains electrically compatible. PS2815-1-V-A is Active status with 1967 units in stock.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). REACH status varies: the main part (PS2815-1-L-A) and PS2815-1-A are REACH Affected, while PS2815-1-F3-A, PS2815-1-V-A, and PS2815-1-V-F3-A are REACH Unaffected.

Packaging Selection: Choose packaging format based on procurement and assembly requirements: Strip format (PS2815-1-A, PS2815-1-V-A) for standard component handling, Cut Tape & Digi-Reel format (PS2815-1-F3-A) for automated pick-and-place systems, or Tape & Reel format (PS2815-1-V-F3-A) for high-volume production.

Frequently Asked Questions (FAQ)

Q: Can PS2815-1-F3-A directly replace PS2815-1-L-A in existing circuit boards?

A: Yes. Both parts are electrically and mechanically identical. The 4-SOIC package footprint (0.173", 4.40mm width) is consistent across all substitutes. PCB layout requires no modification. Verify component mounting height and solder reflow profile compatibility with your assembly process.

Q: What is the difference between the substitute part numbers?

A: All substitute parts share the base part number PS2815-1 with identical electrical specifications. Suffix designations indicate packaging format variations: "-A" denotes Strip packaging, "-F3-A" denotes Cut Tape & Digi-Reel packaging, "-V-A" denotes alternative Strip packaging, and "-V-F3-A" denotes Tape & Reel packaging. These suffixes do not affect functional characteristics.

Q: Are there REACH compliance considerations when selecting a substitute?

A: Yes. The original PS2815-1-L-A is REACH Affected, while PS2815-1-F3-A, PS2815-1-V-A, and PS2815-1-V-F3-A are REACH Unaffected. If your application or supply chain requires REACH Unaffected compliance, select from the latter three part numbers.

Q: Which substitute offers the best inventory availability?

A: PS2815-1-V-F3-A provides the highest inventory with 4351 units in stock. PS2815-1-A follows with 8457 units but carries "Not For New Designs" status. For new designs requiring maximum availability with Active status, PS2815-1-V-F3-A is the preferred selection.

Q: Are there turn-on/turn-off time differences among the substitutes?

A: The main part and most substitutes list turn-on/turn-off time as not specified. PS2815-1-V-A specifies 7µs turn-on and 5µs turn-off time. Rise and fall times remain consistent at 4µs and 5µs across all parts. Verify timing specifications against your circuit's switching requirements.

Q: What is the significance of "Discontinued at DiGi Electronics" for the PS2815-1-L-A?

A: Discontinuation at DiGi Electronics indicates this specific part number variant is no longer actively supported through that distributor channel. Substitute part numbers with Active status (PS2815-1-F3-A, PS2815-1-V-A, PS2815-1-V-F3-A) offer long-term supply assurance for ongoing production or designs with extended lifecycles.
