PS9587L3-AX Optoisolator Equivalent and Substitute Parts

Part Overview

The PS9587L3-AX is a logic output optoisolator designed for high-speed isolation applications requiring 5000Vrms voltage isolation. This device operates at 10Mbps data rate with open collector output configuration in an 8-DIP Gull Wing package. The main part (PS9587L3-AX from CEL) is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active inventory to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS9587L3-AX are categorized into two groups based on electrical compatibility:

Direct Substitutes (PS9587 Series): PS9587L2-AX and PS9587L2-E3-AX share identical electrical specifications with the main part, including 10Mbps data rate, 25mA output current, 75ns propagation delay, and 4.5V~5.5V supply voltage range. Differences are limited to packaging format (Tube vs. Tape & Reel) and product status (Active vs. Discontinued).

Similar Alternatives (PS9513 Series): PS9513L2-AX, PS9513L3-AX, and PS9513L3-E3-AX maintain critical isolation specifications (5000Vrms, 15kV/µs CMTI) and package compatibility but operate at reduced data rate (1Mbps vs. 10Mbps), lower output current (15mA vs. 25mA), extended propagation delay (750ns/500ns vs. 75ns), and wider supply voltage range (4.5V~20V vs. 4.5V~5.5V). These parts are suitable only for lower-speed applications within the same isolation voltage class.

Parameter Comparison

Engineering Selection Recommendations

Recommended Substitutes: PS9587L2-AX and PS9587L2-E3-AX are direct functional equivalents to PS9587L3-AX. Both parts maintain identical electrical performance specifications, support active product status with confirmed inventory availability, and comply with ROHS3 and REACH Unaffected certifications. Selection between these two substitutes depends on procurement requirements: PS9587L2-AX (Tube packaging) for lower-volume applications, PS9587L2-E3-AX (Tape & Reel) for automated assembly and production environments.

Alternative Options: PS9513L2-AX, PS9513L3-AX, and PS9513L3-E3-AX are suitable alternatives only for applications where the 10Mbps data rate requirement can be reduced to 1Mbps operation. These parts provide identical isolation voltage, CMTI specification, and package compatibility but with proportionally reduced output current (15mA) and extended propagation delays. PS9513L3-AX and PS9513L3-E3-AX are preferable within this series due to REACH Unaffected status, while PS9513L2-AX (REACH Affected) may require regulatory review depending on application jurisdiction. Extended operating temperature range (-40°C to 100°C) in PS9513 series provides additional thermal margin for specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can PS9587L2-AX directly replace PS9587L3-AX in existing designs? A: Yes. PS9587L2-AX provides complete electrical equivalency with identical isolation voltage (5000Vrms), data rate (10Mbps), output current (25mA), propagation delay (75ns), and supply voltage range (4.5V~5.5V). Pin configuration and package type (8-DIP Gull Wing) are identical.

Q: What is the difference between PS9587L2-AX and PS9587L2-E3-AX? A: Both parts are electrically identical. The difference is packaging format: PS9587L2-AX is supplied in Tube format for standard handling, while PS9587L2-E3-AX is supplied in Tape & Reel format optimized for automated pick-and-place assembly. Tape & Reel packaging reduces manual handling time in production environments.

Q: When are PS9513 series parts suitable as alternatives? A: PS9513 series parts (PS9513L2-AX, PS9513L3-AX, PS9513L3-E3-AX) are suitable only when application requirements permit operation at 1Mbps data rate instead of the specified 10Mbps. These parts maintain 5000Vrms isolation and 15kV/µs CMTI but reduce output current to 15mA and extend propagation delay to 750ns/500ns.

Q: Are all recommended substitutes ROHS3 compliant? A: Yes. All substitute parts listed are ROHS3 Compliant. Regarding REACH compliance, PS9587 series parts (PS9587L2-AX, PS9587L2-E3-AX) are REACH Unaffected, while PS9513L3-AX and PS9513L3-E3-AX are REACH Unaffected. PS9513L2-AX carries REACH Affected designation and requires regulatory evaluation for specific jurisdictions.

Q: What inventory availability supports long-term supply continuity? A: PS9587L2-AX and PS9587L2-E3-AX maintain active product status with 1252 and 1779 units in stock respectively. PS9513 series alternatives provide substantial inventory depth: PS9513L2-AX (1228 units), PS9513L3-AX (1750 units), and PS9513L3-E3-AX (3100 units). Active product status ensures continued support and availability.

Q: How does operating temperature range affect part selection? A: PS9587 series parts operate across -40°C to 85°C, while PS9513 series parts extend to -40°C to 100°C. For applications requiring extended high-temperature operation, PS9513 series provides 15°C additional thermal headroom.
