PS9303L2-AX Equivalent & Substitute Parts

Part Overview

The PS9303L2-AX is a logic output optoisolator manufactured by Renesas Electronics Corporation, designed for high-speed isolation applications requiring 5000Vrms isolation voltage. This component features push-pull, totem pole output configuration with 1Mbps data rate capability and 15kV/µs common mode transient immunity, making it suitable for industrial control, power management, and communication interface circuits.

The PS9303L2-AX carries a "Not For New Designs" product status. For ongoing production and new design initiatives, identifying equivalent substitute parts with active product status is necessary to ensure long-term supply chain reliability and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS9303L2-AX is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Output Configuration: Push-Pull, Totem Pole (mandatory match)
• Common Mode Transient Immunity: 15kV/µs minimum (mandatory match)
• Data Rate: 1Mbps (mandatory match)
• Output Current: 25 mA per channel (mandatory match)
• Supply Voltage Range: 4.5V ~ 20V (mandatory match)
• Operating Temperature Range: -40°C ~ 100°C (mandatory match)
• Package Type: 6-SOIC surface mount (mandatory match)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (mandatory match)

The PS9303L2-AX and its substitute must belong to the same NEPOC series and maintain identical electrical and mechanical specifications. Packaging format differences (Strip versus Tape & Reel) do not affect functional equivalence but reflect different supply chain configurations.

Parameter Comparison

Engineering Selection Recommendations

The PS9303L2-E3-AX is a direct functional equivalent to the PS9303L2-AX with identical electrical and mechanical specifications across all critical parameters. The primary distinction is product lifecycle status: PS9303L2-E3-AX carries "Active" product status, whereas PS9303L2-AX is designated "Not For New Designs."

For new design implementations and ongoing production requirements, PS9303L2-E3-AX is the appropriate selection. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

The packaging format difference (Strip versus Tape & Reel) reflects supply chain configuration only and does not affect component functionality, electrical performance, or mechanical compatibility. Selection between packaging formats depends on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can PS9303L2-E3-AX be used as a direct replacement for PS9303L2-AX in existing designs?

A: Yes. PS9303L2-E3-AX is functionally equivalent across all electrical and mechanical parameters. No circuit modifications or design changes are required. Both components are pin-compatible, have identical package dimensions, and deliver identical performance characteristics.

Q: What is the significance of the "Not For New Designs" status on PS9303L2-AX?

A: This designation indicates that Renesas Electronics Corporation is not recommending the PS9303L2-AX for new product development. PS9303L2-E3-AX, with "Active" status, is the recommended part for new designs and ensures long-term supply chain availability.

Q: Are there differences in reliability or performance between Strip and Tape & Reel packaging?

A: No. Packaging format (Strip versus Tape & Reel) affects only supply chain logistics and assembly automation compatibility. Component reliability, electrical performance, and mechanical specifications remain identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PS9303L2-AX and PS9303L2-E3-AX are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial applications.

Q: What are the critical parameters that must match for substitution?

A: Isolation voltage (5000Vrms), channel count (1), output configuration (push-pull totem pole), CMTI (15kV/µs), data rate (1Mbps), output current (25 mA), supply voltage range (4.5V ~ 20V), operating temperature (-40°C ~ 100°C), and package type (6-SOIC surface mount) must all match exactly.
