PS9587-AX Equivalent & Substitute Parts

Part Overview

The PS9587-AX is a logic output optoisolator designed for high-speed digital isolation applications. This component provides 5000Vrms galvanic isolation with open collector output configuration, supporting data rates up to 10Mbps. The device is packaged in an 8-DIP through-hole format and operates across the industrial temperature range of -40°C to 85°C.

The PS9587-AX has been discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement capability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS9587-AX is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 5000Vrms minimum. This parameter defines the galvanic isolation capability and cannot be reduced.

Output Configuration: Open collector topology. The output stage architecture must match exactly for circuit compatibility.

Data Rate: 10Mbps minimum. Signal bandwidth requirements must be met or exceeded.

Common Mode Transient Immunity: 15kV/µs minimum. This specification ensures stable operation during high-speed isolation transitions.

Package Format: 8-DIP through-hole with 0.300" (7.62mm) pitch. Physical and electrical pin compatibility is mandatory.

Voltage Supply Range: 4.5V to 5.5V. Operating voltage window must encompass the specified range.

Temperature Range: -40°C to 85°C minimum. Operating environment compatibility is required.

Compliance Standards: ROHS3 compliance and REACH unaffected status must be maintained.

Substitute parts meeting all these criteria are considered direct functional equivalents and may be used interchangeably in circuit applications without modification.

Parameter Comparison

Engineering Selection Recommendations

The PS9587-AX manufactured by Renesas Electronics Corporation is a direct functional equivalent to the discontinued CEL version. Both variants maintain identical electrical specifications across all critical parameters including isolation voltage, output configuration, data rate, and timing characteristics.

Product Status Consideration: The CEL version is discontinued at DiGi Electronics, while the Renesas Electronics version carries preliminary status. For new procurement and design continuity, the Renesas Electronics PS9587-AX is the appropriate selection.

Compliance Alignment: Both variants maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with current manufacturing and environmental standards.

Packaging and Mounting: Both parts utilize identical 8-DIP through-hole packaging with 0.300" (7.62mm) pitch, enabling direct socket compatibility without PCB modification.

Electrical Performance: Identical specifications for isolation voltage (5000Vrms), common mode transient immunity (15kV/µs), data rate (10Mbps), and propagation delay (75ns maximum) confirm functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS9587-AX replace the discontinued CEL PS9587-AX in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is possible without circuit modification or retesting of core isolation and timing functions.

Q: What are the critical parameters that define substitution eligibility for this optoisolator?

A: Substitution requires equivalence in isolation voltage (5000Vrms), output type (open collector), data rate (10Mbps), common mode transient immunity (15kV/µs), package format (8-DIP), supply voltage range (4.5V to 5.5V), and operating temperature range (-40°C to 85°C).

Q: Does the 8-DIP package ensure pin-for-pin compatibility?

A: Yes. Both variants use the 8-DIP (0.300", 7.62mm) through-hole package format, providing identical pin count, pitch, and electrical connectivity. No PCB rework is required for substitution.

Q: Are there compliance differences between the two manufacturers?

A: No. Both the CEL and Renesas Electronics versions maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory standing.

Q: What is the significance of the 15kV/µs common mode transient immunity specification?

A: This parameter defines the maximum rate of voltage change across the isolation barrier that the device can tolerate without output errors. Both variants meet the 15kV/µs minimum requirement, ensuring stable operation in high-speed switching environments.

Q: Can this optoisolator be used in applications requiring higher data rates than 10Mbps?

A: No. The specified maximum data rate is 10Mbps. Applications requiring higher bandwidth require alternative components with higher data rate specifications.
