PS9513L3-AX Optoisolator: Equivalent & Substitute Parts

Part Overview

The PS9513L3-AX is a Logic Output Optoisolator rated for 5000Vrms isolation with 1Mbps data rate and 15kV/µs Common Mode Transient Immunity, packaged in 8-DIP Gull Wing configuration. This component is currently discontinued at DiGi Electronics, making equivalent and substitute parts critical for system maintenance and new design considerations. Alternative models within the PS9513 and PS9587 families provide active product status while maintaining core isolation and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the PS9513L3-AX is organized into two tiers based on allowed electrical and mechanical parameters:

Tier 1: Direct Equivalents (PS9513 Family) These parts maintain identical electrical performance and package configuration. Substitutability is determined by:

• Voltage isolation: 5000Vrms (maintained)
• Common Mode Transient Immunity: 15kV/µs (maintained)
• Data rate: 1Mbps (maintained)
• Package: 8-DIP Gull Wing (maintained)
• Output current: 15mA per channel (maintained)

Direct equivalents within the PS9513 family differ only in packaging format (Tube vs. Tape & Reel) and product status (Active vs. Discontinued).

Tier 2: Similar Alternatives (PS9587 Family) These parts provide higher performance specifications in the same package family. Substitutability introduces parameter differences:

• Data rate: 10Mbps (higher than 1Mbps main part)
• Output current: 25mA per channel (higher than 15mA)
• Propagation delay: 75ns (significantly faster than 750ns/500ns)
• Voltage supply range: 4.5V ~ 5.5V (narrower than 4.5V ~ 20V)
• Operating temperature: -40°C ~ 85°C (narrower than -40°C ~ 100°C)

The PS9587 variants are suitable for applications requiring improved speed performance but demand verification of narrower supply voltage and temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (1:1 Functional Equivalence): Select PS9513L2-AX or PS9513L3-E3-AX when system specifications mandate 1Mbps data rate, 15mA output current, and supply voltage range of 4.5V ~ 20V. Both parts maintain identical electrical characteristics to the discontinued PS9513L3-AX. PS9513L3-E3-AX is recommended for high-volume production due to Tape & Reel packaging and higher inventory availability (3100 pcs). PS9513L2-AX is available in Tube packaging with 1228 pcs in stock.

For Performance-Enhanced Applications: The PS9587L2-AX, PS9587L2-E3-AX, and PS9587L3-AX provide 10Mbps data rate with 25mA output current per channel and reduced propagation delay (75ns). These parts are suitable only for applications operating within the narrower supply voltage range (4.5V ~ 5.5V) and temperature range (-40°C ~ 85°C). All three PS9587 variants carry Active product status with ROHS3 compliance and represent a feature upgrade path for legacy designs.

Compliance and Certification: All substitute parts maintain ROHS3 compliance. The PS9513L2-AX carries REACH Affected status, while PS9513L3-AX, PS9513L3-E3-AX, and all PS9587 variants carry REACH Unaffected status. Component selection should account for supply chain and regulatory requirements in your target market.

Frequently Asked Questions (FAQ)

Q: Can PS9587 optoisolators directly replace PS9513 optoisolators in existing circuits? A: PS9587 parts share the 8-DIP Gull Wing package and 5000Vrms isolation rating but introduce performance differences. The narrower supply voltage range (4.5V ~ 5.5V vs. 4.5V ~ 20V) and temperature range (-40°C ~ 85°C vs. -40°C ~ 100°C) require circuit verification. The 10Mbps data rate and 25mA output current are backward compatible with designs expecting 1Mbps and 15mA specifications. Pin configuration remains identical across both families.

Q: What is the difference between Tube and Tape & Reel packaging for the PS9513? A: Tube and Tape & Reel represent different component packaging formats for identical electrical parts. Tube packaging (PS9513L2-AX, PS9513L3-AX, PS9587L2-AX, PS9587L3-AX) is suitable for smaller order quantities and manual assembly. Tape & Reel packaging (PS9513L3-E3-AX, PS9587L2-E3-AX) is optimized for high-speed automated pick-and-place assembly. Electrical performance and pin configuration are identical between formats.

Q: Why is PS9513L3-AX discontinued when direct alternatives remain in active production? A: Component discontinuation decisions are driven by manufacturer supply chain optimization and market demand. The PS9513L2-AX and PS9513L3-E3-AX from Renesas Electronics provide equivalent functionality as the discontinued CEL PS9513L3-AX. Direct migration to these active parts eliminates long-term supply chain risk.

Q: Which PS9513 variant should be selected for new designs? A: PS9513L3-E3-AX is the recommended choice for new designs. This part offers Active product status, the highest inventory availability (3100 pcs), and Tape & Reel packaging for automated manufacturing. It maintains the full 4.5V ~ 20V supply voltage range and -40°C ~ 100°C operating temperature range of the original PS9513L3-AX.

Q: Are the propagation delay differences between PS9513 (750ns/500ns) and PS9587 (75ns) significant for circuit design? A: Propagation delay differences are significant for timing-sensitive applications. The PS9587 series provides approximately 10× faster propagation delay, suitable for high-speed signal isolation in switched-mode power supplies and high-frequency gate driver circuits. The PS9513 series is appropriate for general-purpose isolation where propagation delay is not a critical timing constraint.
