Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS9324L2-AX is determined by the following critical parameters that must be maintained or exceeded:

• Isolation Voltage: 5000Vrms minimum (primary safety-critical parameter)
• Output Configuration: Open Collector topology
• Number of Channels: 1 channel
• Input Type: DC
• Voltage Supply Range: 2.7V ~ 5.5V compatibility
• Operating Temperature Range: Must support -40°C minimum
• Mounting Type: Surface Mount
• Common Mode Transient Immunity: 15kV/µs minimum
• Data Rate: 10Mbps minimum

The TLP2962(TP1,F) manufactured by Toshiba Semiconductor and Storage meets or exceeds all critical substitution criteria. This part maintains identical isolation voltage, output type, channel count, input type, and supply voltage range. The substitute demonstrates superior performance in common mode transient immunity (20kV/µs vs. 15kV/µs) and data rate capability (15MBd vs. 10Mbps), with extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 110°C).

Parameter Comparison

Engineering Selection Recommendations

The TLP2962(TP1,F) is a direct functional substitute for the PS9324L2-AX based on electrical parameter equivalence and superior performance characteristics. The substitute maintains all critical isolation and safety parameters while providing enhanced performance margins in data rate, output current capability, and common mode transient immunity.

Product Status Consideration: The PS9324L2-AX carries "Not For New Designs" status, indicating Renesas has discontinued active development and support. The TLP2962(TP1,F) maintains "Active" product status from Toshiba, ensuring ongoing availability, technical support, and compliance updates.

Compliance Status: Both components maintain RoHS compliance and REACH unaffected status. The substitute's active product status provides assurance of continued regulatory compliance and supply chain stability.

Package Consideration: The substitute uses 8-SMD packaging versus the main part's 6-SOIC configuration. PCB layout modifications are required to accommodate the different package footprint and pin count. Electrical functionality remains equivalent; physical integration requires design revision.

Frequently Asked Questions (FAQ)

Q: Can the TLP2962(TP1,F) directly replace the PS9324L2-AX without circuit modifications?

A: Electrical functionality is equivalent, but physical integration requires PCB layout changes. The substitute uses 8-SMD packaging with different pin configuration compared to the 6-SOIC main part. Schematic connections remain functionally identical; footprint and placement must be redesigned.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Isolation voltage (5000Vrms), output type (open collector), channel count (1), input type (DC), and supply voltage range (2.7V ~ 5.5V) are the primary determinants. The substitute meets or exceeds all these parameters.

Q: Does the substitute offer performance advantages?

A: Yes. The TLP2962(TP1,F) provides higher data rate capability (15MBd vs. 10Mbps), superior common mode transient immunity (20kV/µs vs. 15kV/µs), higher output current per channel (50mA vs. 25mA), and extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 110°C).

Q: Why is the PS9324L2-AX marked "Not For New Designs"?

A: This designation indicates Renesas has transitioned the product to end-of-life status and is not recommending it for new circuit designs. Existing inventory remains available for legacy system support and maintenance.

Q: Are there supply chain advantages to using the substitute?

A: The TLP2962(TP1,F) maintains active product status with Toshiba, ensuring ongoing availability and technical support. The main part's end-of-life status may result in limited future inventory and extended lead times.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS compliant and REACH unaffected. The substitute's active status provides assurance of continued regulatory compliance maintenance.
