Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS9331L-AX is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Technology: Optical Coupling (mandatory match)
• Common Mode Transient Immunity: 50kV/µs minimum (mandatory match)
• Propagation Delay: 175ns maximum for both tpLH and tpHL (mandatory match)
• Peak Output Current: 2.5A (mandatory match)
• Output Supply Voltage Range: 15V ~ 30V (mandatory match)
• Package Type: 6-SOIC / 6-SDIP Gull Wing (mandatory match)
• Operating Temperature Range: -40°C ~ 125°C (mandatory match)

The PS9331L2-E3-AX qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The PS9331L2-E3-AX is a direct electrical and mechanical equivalent to the PS9331L-AX. Selection between these parts should be based on the following factors:

Product Status Consideration: The PS9331L-AX carries "Not For New Designs" status, indicating end-of-life classification. The PS9331L2-E3-AX maintains "Active" product status with Renesas Electronics Corporation, ensuring continued availability and manufacturing support.

Compliance and Certification: Both parts maintain identical compliance certifications including CSA, SEMKO, and UL approvals. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Packaging Format: The primary operational difference is packaging format. The PS9331L-AX is supplied in Strip format, while the PS9331L2-E3-AX is supplied in Tape & Reel (TR) format. This distinction affects procurement, handling, and assembly processes but does not impact electrical performance or functional compatibility.

Inventory Availability: The PS9331L2-E3-AX demonstrates higher current inventory levels (2895 Pcs) compared to PS9331L-AX (744 Pcs), supporting supply chain continuity for ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can PS9331L2-E3-AX directly replace PS9331L-AX in existing circuit designs?

A: Yes. All electrical parameters, isolation voltage, output current ratings, timing specifications, and operating temperature ranges are identical. The components are pin-compatible and functionally equivalent. Packaging format differs (Strip vs. Tape & Reel) but does not affect circuit-level compatibility.

Q: What is the significance of the "Not For New Designs" status on PS9331L-AX?

A: This designation indicates the part has reached end-of-life status with the manufacturer. While existing inventory may remain available, Renesas Electronics Corporation does not recommend this part for new product development. The PS9331L2-E3-AX, with "Active" status, is the recommended alternative for both new designs and replacement applications.

Q: Are there differences in isolation voltage or safety certifications between these parts?

A: No. Both parts provide 5000Vrms isolation and hold identical safety approvals from CSA, SEMKO, and UL. Regulatory compliance is equivalent.

Q: How does Tape & Reel packaging differ from Strip packaging?

A: Strip packaging supplies components in loose strips suitable for manual handling and small-quantity applications. Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated assembly equipment and high-volume production. Both formats contain identical components with no electrical or functional differences.

Q: Are the propagation delay and timing specifications identical?

A: Yes. Both parts specify maximum propagation delay of 175ns for both tpLH and tpHL, maximum pulse width distortion of 75ns, and typical rise/fall times of 40ns. Timing performance is equivalent.

Q: What is the operating temperature range for both parts?

A: Both PS9331L-AX and PS9331L2-E3-AX operate across -40°C to 125°C, providing identical thermal performance specifications.
