Key Parameters

Substitute Part Grouping Explanation

The LTV-816S-TA1 qualifies as a direct substitute for the PC817X1CSP9F based on the following critical parameters:

• Isolation Voltage: Both parts maintain 5000Vrms isolation rating
• Channel Configuration: Single channel in both parts
• Current Transfer Ratio: Identical specifications (50% minimum, 600% maximum @ 5mA)
• Output Characteristics: Transistor output with matching 80V maximum output voltage and 50mA per-channel current rating
• Saturation Voltage: Both specify 200mV maximum Vce saturation
• Rise/Fall Time: Identical timing specifications (4µs rise, 3µs fall)
• Package Type: Both use 4-SMD Gull Wing surface mount configuration
• Input Type: DC input in both parts

The substitute part operates across a wider temperature range (-50°C ~ 110°C versus -30°C ~ 100°C) and carries ROHS3 compliance with REACH Unaffected status, providing enhanced environmental certification coverage.

Parameter Comparison

Engineering Selection Recommendations

Both the PC817X1CSP9F and LTV-816S-TA1 are active production parts with current availability. The LTV-816S-TA1 offers extended operating temperature range coverage and ROHS3 certification status, which may be advantageous for applications requiring enhanced environmental compliance documentation. The PC817X1CSP9F remains suitable for applications within its specified temperature range. Selection between these parts should be based on supply availability, regional sourcing requirements, and specific compliance certifications mandated by the end application or customer specifications.

Frequently Asked Questions (FAQ)

Q: Can the LTV-816S-TA1 replace the PC817X1CSP9F in existing designs?

A: Yes. Both parts share identical electrical specifications for isolation voltage, current transfer ratio, output voltage, output current, and saturation voltage. The 4-SMD Gull Wing package is identical, allowing direct PCB footprint compatibility without layout modifications.

Q: What is the difference in operating temperature ranges?

A: The PC817X1CSP9F operates from -30°C to 100°C, while the LTV-816S-TA1 operates from -50°C to 110°C. For applications operating within the PC817X1CSP9F range, both parts perform identically. The LTV-816S-TA1 provides extended coverage for wider temperature environments.

Q: Are there packaging differences between these parts?

A: Both parts use 4-SMD Gull Wing surface mount packages. The PC817X1CSP9F is supplied in standard packaging, while the LTV-816S-TA1 is supplied in Tape & Reel format. This affects handling and assembly processes but does not impact electrical performance or PCB mounting.

Q: What compliance certifications apply to each part?

A: The PC817X1CSP9F carries RoHS Compliant status. The LTV-816S-TA1 carries ROHS3 Compliant status and is REACH Unaffected. Applications requiring specific compliance documentation should reference the appropriate part certification.

Q: Are the rise and fall times identical?

A: Yes. Both parts specify 4µs rise time and 3µs fall time, ensuring identical switching performance in circuit applications.
