Substitute Part Grouping Explanation

Substitution of the PS9814-2-A is based on strict matching of electrical and mechanical parameters. The key substitution criteria are:

• Isolation Voltage: 2500 Vrms (exact match required)
• Number of Channels: 2 channels (exact match required)
• Output Type: Open Collector (exact match required)
• Data Rate: 10 Mbps (exact match required)
• Current - Output / Channel: 25 mA (exact match required)
• Package / Case: 8-SOIC 0.154" width (exact match required)
• Voltage - Supply: 4.5 V ~ 5.5 V (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)

Both substitute parts (PS9817A-2-AX and PS9817A-2-F3-AX) satisfy all matching criteria and are manufactured by Renesas Electronics Corporation under the NEPOC series designation.

Parameter Comparison

Engineering Selection Recommendations

PS9817A-2-F3-AX is the preferred substitute for new designs. This part is classified as Active with ROHS3 compliance and REACH unaffected status, providing extended product lifecycle support and regulatory alignment. The device is available in Cut Tape and Digi-Reel packaging configurations.

PS9817A-2-AX serves as an alternative substitute with equivalent electrical characteristics. This part holds Not For New Designs status and is supplied in Bulk packaging. Both Renesas substitutes feature improved common-mode transient immunity (15 kV/µs versus 10 kV/µs) and reduced fall time (5 ns versus 10 ns), characteristics that enhance performance margins without affecting core functional compatibility.

Frequently Asked Questions (FAQ)

Q: Are PS9817A-2-AX and PS9817A-2-F3-AX pin-compatible with PS9814-2-A? A: Both substitute parts share identical package specifications (8-SOIC, 0.154" width) and electrical interface requirements, enabling direct substitution in existing designs without circuit modifications.

Q: What are the key differences between the substitute parts? A: PS9817A-2-F3-AX carries Active product status with current manufacturing support, while PS9817A-2-AX carries Not For New Designs status. Both employ identical core specifications and are functionally equivalent.

Q: How do improved CMTI specifications affect substitution? A: The substitute parts provide 15 kV/µs common-mode transient immunity compared to 10 kV/µs in the original part. This enhancement maintains backward compatibility while improving performance margins in high-noise environments.

Q: What packaging formats are available for substitute parts? A: PS9817A-2-F3-AX is available in Cut Tape and Digi-Reel formats suitable for automated assembly. PS9817A-2-AX is available in Bulk packaging for alternate supply chains.

Q: Are there compliance differences between the main part and substitutes? A: The substitutes are ROHS3 compliant and REACH unaffected, providing improved regulatory compliance. The original PS9814-2-A carries REACH Affected status, limiting use in certain applications.
