PS2815-4 Optoisolator Equivalent and Substitute Parts

Part Overview

The PS2815-4 is a 4-channel optoisolator with transistor output rated for 2500Vrms isolation. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design work and production planning. Active alternatives from Renesas Electronics Corporation provide equivalent electrical performance with improved compliance status and broader packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2815-4 is based on matching critical electrical and mechanical parameters. All qualified substitute parts maintain identical isolation voltage (2500Vrms), channel configuration (4 channels), current transfer ratio specifications (100%-400% @ 1mA), output voltage rating (40V maximum), per-channel output current (40mA), and package form factor (16-SOIC, 0.173" width, 4.40mm).

The substitute parts are categorized into two groups:

Similar Manufacturer Parts (Direct Substitutes):

• PS2815-4-F3-A
• PS2815-4-F3-L-A
• PS2815-4-V-A
• PS2815-4-V-F3-A

Parametric Equivalent:

• PS2815-4-L-A

All substitute parts are manufactured by Renesas Electronics Corporation and carry active product status. Substitution is valid across all variants provided that the electrical specifications match those detailed in the Key Parameters table, and the package form factor remains 16-SOIC.

Parameter Comparison

Engineering Selection Recommendations

Selection among the qualified substitute parts is based on product status, compliance requirements, and packaging availability.

All Renesas variants (PS2815-4-F3-A, PS2815-4-F3-L-A, PS2815-4-V-A, PS2815-4-V-F3-A, and PS2815-4-L-A) carry active product status compared to the obsolete PS2815-4. All substitute parts are ROHS3 compliant, providing improved environmental compliance over the original non-compliant part.

PS2815-4-F3-A, PS2815-4-F3-L-A, PS2815-4-V-A, and PS2815-4-V-F3-A are designated as similar manufacturer parts and represent the primary substitution choice. PS2815-4-L-A is classified as a parametric equivalent and serves as an alternative when specific packaging or supply constraints apply.

The PS2815-4-L-A carries REACH Affected status, whereas PS2815-4-F3-A, PS2815-4-F3-L-A, PS2815-4-V-A, and PS2815-4-V-F3-A carry REACH Unaffected status. This distinction influences regulatory documentation requirements in applications subject to REACH compliance verification.

Frequently Asked Questions (FAQ)

Q: What parameters must match for a part to serve as a substitute for the PS2815-4?

A: Substitute parts must maintain the following specifications: 4-channel configuration, 2500Vrms isolation voltage, 100%-400% current transfer ratio at 1mA input, 40V maximum output voltage, 40mA maximum output current per channel, 300mV maximum Vce saturation, 1.15V typical forward voltage, and 16-SOIC package form factor with 0.173" width and 4.40mm physical dimensions.

Q: Are all listed substitute parts pin-compatible with the PS2815-4?

A: All substitute parts listed use the identical 16-SOIC package form factor with matching pinout. The 0.173" width and 4.40mm package dimensions ensure mechanical and electrical pin-level compatibility. Substitution on printed circuit boards designed for the PS2815-4 requires no layout modifications.

Q: What is the difference between similar manufacturer parts and the parametric equivalent?

A: Similar manufacturer parts (PS2815-4-F3-A, PS2815-4-F3-L-A, PS2815-4-V-A, PS2815-4-V-F3-A) are direct substitutes with identical part-number lineage within the Renesas product family. The parametric equivalent (PS2815-4-L-A) matches electrical and mechanical parameters but may differ in variant designation. Both categories are electrically interchangeable provided all specifications align with the Key Parameters section.

Q: Why does the original PS2815-4 show obsolete status while substitutes are active?

A: The PS2815-4 manufactured by CEL is no longer in production. Renesas Electronics Corporation offers equivalent product lines with active manufacturing status and improved environmental compliance (ROHS3 certification). Selection of active parts ensures continued supply availability and compliance with modern regulatory requirements.

Q: Are there packaging differences among the substitute parts?

A: Packaging options vary among substitutes. PS2815-4-F3-A is supplied in Cut Tape (CT) and Digi-Reel format. PS2815-4-F3-L-A and PS2815-4-L-A use standard packaging. PS2815-4-V-A is supplied in Strip format. PS2815-4-V-F3-A is supplied in Tape & Reel (TR) format. All maintain the identical 16-SOIC physical form factor; packaging designation reflects supply and handling format only.
