ACPL-824-360E Equivalent & Substitute Parts

Part Overview

The ACPL-824-360E is an optoisolator with transistor output manufactured by Broadcom Limited. This 2-channel device provides 5000Vrms isolation and is designed for AC/DC input applications requiring galvanic isolation in surface mount configurations. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range, enabling design flexibility and supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the ACPL-824-360E is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 5000Vrms (mandatory match)
Channel Count: 2 channels (mandatory match)
Output Type: Transistor output (mandatory match)
Current Transfer Ratio Range: 20% to 300% @ 1mA (mandatory match)
Rise / Fall Time: 4µs / 3µs (mandatory match)
Input Type: AC, DC capability (mandatory match)
Package: 8-SMD, Gull Wing (mandatory match for PCB compatibility)
Operating Temperature Range: -30°C ~ 100°C (mandatory match)
Compliance: RoHS3 and REACH status (mandatory match)

The LTV-824S-TA1 manufactured by Lite-On Inc. meets all mandatory substitution criteria. Packaging differs (Tape & Reel vs. Tube), which affects supply chain handling but not electrical or mechanical performance on the PCB.

Engineering Selection Recommendations

Both ACPL-824-360E and LTV-824S-TA1 are active production parts with identical RoHS3 and REACH compliance status. Selection between these parts should be based on:

Maximum Output Voltage Requirement: The ACPL-824-360E supports 70V maximum output, while the LTV-824S-TA1 is rated to 35V maximum output. Applications requiring output voltages above 35V must use the ACPL-824-360E.

Packaging and Supply Chain: The ACPL-824-360E is supplied in Tube packaging, while the LTV-824S-TA1 is supplied in Tape & Reel format. Selection may depend on assembly process requirements and inventory management practices.

Electrical Performance: All other electrical parameters, including isolation voltage, current transfer ratio, switching times, and operating temperature range, are identical between both parts.

Frequently Asked Questions (FAQ)

Q: Can LTV-824S-TA1 replace ACPL-824-360E in all applications?

A: LTV-824S-TA1 is a direct substitute for ACPL-824-360E only when the application's maximum output voltage requirement does not exceed 35V. If your circuit requires output voltages between 35V and 70V, the ACPL-824-360E must be used.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in a plastic tube for manual handling and smaller quantities. Tape & Reel packaging supplies components on a continuous reel for automated assembly equipment. Both formats contain identical components; packaging selection depends on manufacturing process and volume requirements.

Q: Are the isolation voltage and current transfer ratio specifications identical?

A: Yes. Both ACPL-824-360E and LTV-824S-TA1 provide 5000Vrms isolation and identical current transfer ratio specifications of 20% to 300% @ 1mA.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: What are the switching time specifications?

A: Both parts have identical rise and fall times of 4µs and 3µs respectively, ensuring equivalent performance in timing-critical applications.
