Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS9552L3-AX is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 5000Vrms minimum
• Single-channel configuration
• Peak output current: 2.5A
• Output supply voltage range: 15V ~ 30V
• Surface mount 8-SMD gull wing package
• Optical coupling technology
• ROHS3 compliance

The PS9531L3-AX qualifies as a direct substitute based on matching all mandatory electrical and mechanical parameters. While the PS9531L3-AX demonstrates improved performance characteristics (higher CMTI, faster propagation delay, lower PWD), these enhancements do not disqualify it from substitution—they represent performance upgrades within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

The PS9531L3-AX is the qualified substitute for the obsolete PS9552L3-AX. Selection is based on the following engineering criteria:

• Both components maintain identical isolation voltage (5000Vrms) and peak output current (2.5A) specifications
• Both support the same output supply voltage range (15V ~ 30V)
• Both are packaged in 8-SMD gull wing configuration for direct PCB compatibility
• The PS9531L3-AX holds active product status, ensuring long-term availability and supply chain continuity
• Both components carry ROHS3 compliance and REACH affected designation
• The PS9531L3-AX extends operating temperature range to -40°C ~ 125°C, providing broader thermal coverage
• Regulatory approvals for PS9531L3-AX (CSA, SEMKO, UL) satisfy industrial safety requirements

Frequently Asked Questions (FAQ)

Q: Can PS9531L3-AX directly replace PS9552L3-AX in existing designs?

A: Yes. Both components share identical isolation voltage, channel count, peak output current, output supply voltage range, and package configuration. Direct substitution is electrically and mechanically compatible.

Q: What are the key differences between these parts?

A: The PS9531L3-AX provides improved performance metrics: 50kV/µs CMTI versus 25kV/µs, 175ns propagation delay versus 500ns, and 75ns pulse width distortion versus 300ns. The PS9531L3-AX also extends the operating temperature range to -40°C ~ 125°C. These represent performance enhancements, not functional changes.

Q: Is the 8-SMD gull wing package identical between both parts?

A: Yes. Both components use 8-SMD gull wing surface mount packaging, ensuring footprint compatibility on PCBs designed for the PS9552L3-AX.

Q: Why is PS9552L3-AX classified as obsolete?

A: The PS9552L3-AX has reached end-of-life status. The PS9531L3-AX represents the active product line continuation with equivalent functionality and enhanced performance characteristics.

Q: Are there compliance or certification differences?

A: Both components are ROHS3 compliant and REACH affected. The PS9531L3-AX carries CSA, SEMKO, and UL approvals. The PS9552L3-AX carries BSI, CSA, DEMKO, FIMKO, NEMKO, SEMKO, and UL approvals. Both meet industrial safety standards.

Q: What is the moisture sensitivity level for these components?

A: Both PS9552L3-AX and PS9531L3-AX carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
