Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PC817X2CSP9F are identified based on strict equivalence of the following critical parameters:

• Single channel configuration (Number of Channels: 1)
• Isolation voltage rating (5000Vrms minimum)
• Transistor output type
• Current transfer ratio range (50% to 600% @ 5mA)
• Rise and fall time specifications (4µs, 3µs)
• Maximum output voltage (80V)
• Maximum output current per channel (50mA)
• Vce saturation specification (200mV maximum)
• Surface mount package in 4-SMD Gull Wing configuration

The LTV-816S-TA1 meets all these electrical and mechanical requirements and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the PC817X2CSP9F and LTV-816S-TA1 are active production parts with equivalent electrical and mechanical specifications. The LTV-816S-TA1 offers an extended operating temperature range (-50°C ~ 110°C versus -30°C ~ 100°C) and ROHS3 compliance status. Selection between these parts should be based on supply availability, packaging requirements (Tape & Reel for LTV-816S-TA1), and specific temperature operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can the LTV-816S-TA1 directly replace the PC817X2CSP9F in existing designs?

A: Yes. Both parts share identical electrical specifications for isolation voltage, current transfer ratio, output voltage and current ratings, and switching characteristics. Both use the same 4-SMD Gull Wing surface mount package. No circuit modifications are required.

Q: What is the difference in operating temperature ranges?

A: The PC817X2CSP9F operates from -30°C to 100°C, while the LTV-816S-TA1 operates from -50°C to 110°C. The LTV-816S-TA1 provides extended temperature coverage at both extremes. Selection depends on the thermal requirements of your application.

Q: Are there packaging differences between these parts?

A: The PC817X2CSP9F is supplied in standard packaging, while the LTV-816S-TA1 is supplied in Tape & Reel (TR) format. Both use identical 4-SMD Gull Wing component packages suitable for automated assembly.

Q: What compliance certifications apply to each part?

A: The PC817X2CSP9F carries RoHS Compliant certification. The LTV-816S-TA1 carries ROHS3 Compliant certification and is REACH Unaffected. Both meet environmental compliance requirements for their respective markets.

Q: Are the electrical characteristics identical between these optoisolators?

A: Yes. Both parts have identical specifications for isolation voltage (5000Vrms), current transfer ratio (50% to 600% @ 5mA), rise/fall times (4µs, 3µs), output voltage (80V maximum), output current (50mA), and Vce saturation (200mV maximum).
