ISLT1009V Optoisolator Equivalent & Substitute Parts

Part Overview

The ISLT1009V is an optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 5000Vrms with a single channel configuration in a 4-SMD surface mount package. The device is classified as Active status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

• Current Transfer Ratio (Min): 200% @ 5mA
• Current Transfer Ratio (Max): 400% @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Voltage - Forward (Vf) (Typ): 1.45V
• Current - DC Forward (If) (Max): 60 mA
• Vce Saturation (Max): 300mV
• Operating Temperature: -55°C ~ 110°C
• Input Type: DC

Mechanical Parameters (Compatible):

• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Both parts meet identical electrical specifications and share compatible mechanical characteristics, establishing direct substitution capability within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

Both the ISLT1009V and APC-1019 maintain Active product status with full RoHS3 compliance and REACH unaffected classification. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical performance differences. The APC-1019 exhibits slower rise and fall times (6µs, 8µs versus 2µs, 3µs), which may be relevant for timing-critical applications but does not prevent substitution in standard isolation applications. Both components carry identical isolation voltage ratings, output specifications, and thermal operating ranges, supporting direct interchange in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the APC-1019 directly replace the ISLT1009V in existing designs?

A: Yes. Both parts share identical electrical specifications for isolation voltage, current transfer ratio, output voltage and current ratings, and saturation characteristics. Surface mount package compatibility and identical operating temperature ranges support direct substitution.

Q: What is the difference in rise and fall times between these parts?

A: The ISLT1009V specifies 2µs and 3µs rise and fall times, while the APC-1019 specifies 6µs and 8µs. This difference affects switching speed but does not prevent substitution in applications where the slower timing of the APC-1019 is acceptable.

Q: Are both parts RoHS compliant?

A: Yes. Both the ISLT1009V and APC-1019 are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current environmental and reliability standards.

Q: Do these parts require different PCB footprints?

A: No. Both parts use 4-SMD Gull Wing surface mount packages, requiring identical PCB footprints and assembly processes.

Q: What is the isolation voltage rating for both parts?

A: Both the ISLT1009V and APC-1019 provide 5000Vrms galvanic isolation, supporting high-voltage isolation applications.
