Key Parameters

Substitute Part Grouping Explanation

Substitution classification follows two distinct categories based on preserved electrical performance:

Direct Substitutes maintain identical critical electrical parameters: 10Mbps data rate, 25mA output current per channel, 4.5V–5.5V supply voltage range, and -40°C to 85°C operating temperature. These parts differ only in packaging configuration (Tube vs. Tape & Reel) and product status availability. The PS9587L2-AX, PS9587L2-E3-AX, and PS9587L3-AX preserve all functional specifications and are electrically interchangeable with the original PS9587L3-E3-AX.

Similar Substitutes provide equivalent 5000Vrms isolation and 15kV/µs CMTI but with reduced data rate (1Mbps versus 10Mbps) and lower output current (15mA versus 25mA). The PS9513L2-AX, PS9513L3-AX, and PS9513L3-E3-AX represent broader compatibility options where application bandwidth and sink current requirements permit operational reduction. These alternatives extend the supply voltage range to 4.5V–20V and operating temperature to -40°C to 100°C.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Equivalence: Select PS9587L2-E3-AX when Tape & Reel packaging is required for automated assembly operations. This part maintains identical electrical performance, carries active product status, and holds ROHS3 compliance with REACH Unaffected designation. When Tube packaging is acceptable, PS9587L3-AX or PS9587L2-AX provide equivalent functionality with established supply chain availability.

For Reduced Performance Parameters: The PS9513 series (PS9513L2-AX, PS9513L3-AX, PS9513L3-E3-AX) provides electrical isolation and CMTI specifications identical to the original component but supports lower bandwidth applications. These alternatives are appropriate when circuit design permits 1Mbps data rates, 15mA output current, and extended supply voltage operation. PS9513L3-E3-AX is recommended for high-volume Tape & Reel applications within this reduced-performance category.

Compliance Considerations: All substitutes conform to ROHS3 requirements and MSL 1 classification. PS9513L2-AX carries REACH Affected status; applications subject to REACH regulatory oversight should prioritize PS9513L3-AX or PS9513L3-E3-AX for REACH Unaffected compliance.

Frequently Asked Questions (FAQ)

Q: Can PS9587L2-E3-AX directly replace PS9587L3-E3-AX? A: Yes. Both parts are electrically identical across all critical parameters: 10Mbps data rate, 25mA output current, 5000Vrms isolation, 15kV/µs CMTI, and identical propagation delays. Substitution is valid for any circuit application designed for the original part.

Q: What is the difference between PS9587L2-AX and PS9587L2-E3-AX? A: The difference is packaging format. PS9587L2-AX is supplied in Tube packaging; PS9587L2-E3-AX is supplied in Tape & Reel (TR) configuration. Electrical specifications are identical. Tube packaging is used for manual handling and small-quantity orders. Tape & Reel is standard for automated pick-and-place assembly.

Q: Can PS9513L3-E3-AX be used as a substitute for PS9587L3-E3-AX? A: PS9513L3-E3-AX provides the same 5000Vrms isolation, 15kV/µs CMTI, 1-channel configuration, and 8-DIP Gull Wing package. However, it operates at 1Mbps data rate (versus 10Mbps) and provides 15mA output current (versus 25mA). Substitution is valid only if the circuit design accommodates reduced bandwidth and sink current specifications.

Q: What are the key parameters that determine substitutability? A: Substitutability depends on Data Rate, Output Current per Channel, Supply Voltage Range, and Operating Temperature Range. Direct substitutes maintain all four parameters. Similar substitutes preserve Isolation Voltage and CMTI but reduce Data Rate and Output Current while extending voltage and temperature tolerances.

Q: Are all suggested substitutes ROHS3 compliant? A: Yes. All listed alternatives—PS9587L2-AX, PS9587L2-E3-AX, PS9587L3-AX, PS9513L2-AX, PS9513L3-AX, and PS9513L3-E3-AX—carry ROHS3 Compliant designation.

Q: Does REACH status affect component selection? A: REACH Affected designation indicates that the substance composition is subject to REACH regulatory monitoring. For applications with regulatory REACH requirements, PS9513L3-AX and PS9513L3-E3-AX provide REACH Unaffected alternatives. PS9587L2-AX, PS9587L2-E3-AX, and PS9587L3-AX all carry REACH Unaffected status.
