PS9513-AX Equivalent & Substitute Parts

Part Overview

The PS9513-AX is a logic output optoisolator featuring 5000Vrms isolation, open collector output configuration, and 1Mbps data rate capability in an 8-DIP through-hole package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement needs. The part operates across a -40°C to 100°C temperature range with 15kV/µs common mode transient immunity, suitable for industrial isolation applications requiring galvanic separation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS9513-AX is determined by the following critical parameters: isolation voltage (5000Vrms), output configuration (open collector), number of channels (1), common mode transient immunity (15kV/µs), package type (8-DIP through-hole), and operating temperature range (-40°C to 100°C). Parts are classified into two substitution categories:

Direct Equivalents: Parts maintaining identical electrical specifications and package dimensions (0.300" DIP pitch). These parts satisfy all functional requirements of the original PS9513-AX without design modification.

Similar Substitutes: Parts with enhanced performance characteristics (higher data rate, faster propagation delay, increased output current) but with modified supply voltage range and operating temperature limits. These parts provide functional compatibility with potential design trade-offs.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: The PS9513-AX manufactured by Renesas Electronics Corporation is the primary direct equivalent, maintaining active product status and identical electrical and mechanical specifications to the discontinued CEL version. This part is suitable for direct substitution without circuit modification.

Alternative Direct Equivalent: The PS9513L1-AX provides equivalent electrical performance with an alternative package pitch (0.400" vs. 0.300" DIP spacing). Selection between PS9513-AX and PS9513L1-AX depends on PCB layout constraints and socket compatibility. Both parts maintain active product status and full compliance with ROHS3 and MSL requirements.

Enhanced Performance Substitutes: The PS9587-AX and PS9587L1-AX optoisolators offer superior performance characteristics including 10Mbps data rate, 75ns propagation delay, and 25mA output current. These parts operate within a restricted supply voltage range (4.5V to 5.5V versus 4.5V to 20V) and reduced operating temperature range (-40°C to 85°C versus -40°C to 100°C). The PS9587L1-AX maintains active product status, while PS9587-AX is classified as preliminary. Selection of PS9587 series components is appropriate for applications requiring higher speed operation within the specified voltage and temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can PS9513L1-AX replace PS9513-AX directly on existing PCBs?

A: Electrical substitution is complete; however, the PS9513L1-AX uses 0.400" DIP pitch spacing compared to the 0.300" pitch of PS9513-AX. Direct socket replacement is not possible without PCB modification or adapter hardware. Verify PCB footprint compatibility before selection.

Q: What are the key differences between PS9513-AX and PS9587-AX?

A: The PS9587-AX provides 10x higher data rate (10Mbps vs. 1Mbps), 10x faster propagation delay (75ns vs. 750ns/500ns), and higher output current (25mA vs. 15mA). The PS9587-AX restricts supply voltage to 4.5V–5.5V and operating temperature to -40°C–85°C. Selection depends on application speed requirements and power supply constraints.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts (PS9513-AX, PS9513L1-AX, PS9587-AX, PS9587L1-AX) are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity). Compliance documentation is consistent across all options.

Q: Which substitute part has the best availability?

A: PS9513-AX (Renesas) maintains the highest inventory at 6850 pieces. PS9513L1-AX has 1981 pieces in stock. PS9587L1-AX has 1577 pieces. PS9587-AX has 1051 pieces. Inventory levels are subject to change; verify current stock with supplier.

Q: Can PS9587 series parts operate at temperatures above 85°C?

A: No. PS9587-AX and PS9587L1-AX are specified for -40°C to 85°C operation. Applications requiring operation to 100°C must use PS9513-AX or PS9513L1-AX variants.

Q: What is the significance of the "L1" designation in part numbers?

A: The "L1" suffix indicates an alternative package pitch (0.400" DIP spacing) compared to standard 0.300" DIP. Electrical specifications remain identical to non-L1 variants. Selection is based on PCB layout and socket requirements.

Q: Is PS9587-AX suitable for production designs?

A: PS9587-AX is classified as preliminary product status. PS9587L1-AX is classified as active. For production designs, PS9587L1-AX is the recommended PS9587 series selection. PS9513-AX and PS9513L1-AX remain the most stable choices with active status and extended operating range.
