PS2833-1-A Equivalent & Substitute Parts

Part Overview

The PS2833-1-A is a 2500Vrms Darlington output optoisolator designed for galvanic isolation applications in 4-SOIC surface mount packaging. The main part is currently discontinued at DiGi Electronics but remains available through inventory channels. Locating direct equivalents and functional substitutes is essential for design continuation and long-term production supply.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS2833-1-A are qualified based on electrical and mechanical compatibility across the following parameters:

• Isolation voltage: 2500Vrms
• Output configuration: Single channel Darlington
• Current transfer ratio: 400% to 4500% @ 1mA
• Maximum output voltage: 350V
• Output current capacity: 60mA per channel
• Rise/fall time characteristics: 20µs rise, 5µs fall
• Operating temperature: -55°C to +100°C
• Physical package: 4-SOIC surface mount, 0.173" width, 4.40mm package width

Two substitute parts are qualified as equivalent options: PS2833-1-F3-A (direct manufacturer equivalent in Tape & Reel packaging) and PS2833-1-A (parametric equivalent in Strip packaging, same manufacturer).

Parameter Comparison

Engineering Selection Recommendations

PS2833-1-F3-A (Direct Manufacturer Equivalent): This part carries Active product status from Renesas Electronics Corporation, indicating full ongoing support and design approval. It provides identical electrical parameters and operational characteristics to the main part. The Tape & Reel packaging format is suitable for high-volume automated assembly. This option is the primary recommendation for new production designs and component sourcing.

PS2833-1-A (Parametric Equivalent): This Renesas option shares all electrical parameters with the original part and is available in Strip packaging. However, it carries a "Not For New Designs" status, which indicates the manufacturer considers it obsolete for new applications. This option may be considered only for legacy system maintenance or when alternative sources are unavailable.

Frequently Asked Questions (FAQ)

Q: Can PS2833-1-F3-A directly replace the original PS2833-1-A in my circuit? A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 2500Vrms isolation voltage, single-channel Darlington output, 400%-4500% current transfer ratio, 350V maximum output voltage, 60mA output current, and identical rise/fall time specifications. The package type is the same 4-SOIC (0.173", 4.40mm width) surface mount configuration.

Q: What is the difference between the two substitute parts? A: PS2833-1-F3-A is available in Tape & Reel packaging (appropriate for automated production) and has Active product status. PS2833-1-A is available in Strip packaging and carries "Not For New Designs" status. Electrically, both are identical to the original part.

Q: Are there any compliance or regulatory differences? A: All three parts carry ROHS3 Compliant status, have identical Moisture Sensitivity Level ratings (1 - Unlimited), and share the same REACH and ECCN classifications. No compliance restrictions exist between the parts.

Q: What packaging format should I choose? A: For new production, Tape & Reel (PS2833-1-F3-A) is standard for automated pick-and-place assembly. Strip packaging (PS2833-1-A) may be used where manual assembly or lower-volume production is appropriate, though this part is marked "Not For New Designs."

Q: How do I verify compatibility with my circuit design? A: Confirm that your circuit design parameters fall within these specifications: 2500Vrms isolation requirement, single-channel isolation, Darlington output topology, output voltage not exceeding 350V, output current not exceeding 60mA per channel, and operating temperature range -55°C to +100°C. All three qualified parts meet these criteria identically.
