ACPL-824-300E Equivalent & Substitute Parts

Part Overview

The ACPL-824-300E 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 (MSL 1).

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 alternatives.

Key Parameters

Substitute Part Grouping Explanation

The LTV-824S-TA1 manufactured by Lite-On Inc. qualifies as a direct substitute based on the following critical parameters:

• Identical 2-channel configuration with 5000Vrms isolation voltage
• Matching current transfer ratio specifications (20% min, 300% max @ 1mA)
• Equivalent rise/fall time performance (4µs, 3µs)
• Identical AC/DC input capability and transistor output topology
• Same 50mA output current per channel and 200mV Vce saturation maximum
• Matching operating temperature range (-30°C ~ 100°C)
• Identical 8-SMD, Gull Wing package and surface mount configuration
• Equivalent compliance certifications (RoHS3, REACH Unaffected, EAR99)

The primary difference is maximum output voltage (35V vs 70V), which represents a design constraint that must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status with full regulatory compliance. Selection between ACPL-824-300E and LTV-824S-TA1 is determined by maximum output voltage requirements:

• Use ACPL-824-300E when application circuits require output voltages up to 70V
• Use LTV-824S-TA1 when application circuits operate at output voltages up to 35V

Both devices are RoHS3 compliant with unlimited moisture sensitivity rating, suitable for standard PCB assembly processes without special handling. Packaging format differs (Tube vs Tape & Reel), which may affect procurement and automated assembly considerations.

Frequently Asked Questions (FAQ)

Q: Can LTV-824S-TA1 replace ACPL-824-300E in all applications?

A: Substitution is valid only when the application circuit operates at output voltages of 35V or lower. The LTV-824S-TA1 has a maximum output voltage rating of 35V compared to 70V for the ACPL-824-300E. All other electrical parameters are equivalent.

Q: Are the isolation voltage ratings identical?

A: Yes. Both parts provide 5000Vrms isolation voltage with identical current transfer ratio specifications (20% minimum, 300% maximum @ 1mA).

Q: What is the difference in packaging?

A: ACPL-824-300E is supplied in Tube packaging, while LTV-824S-TA1 is supplied in Tape & Reel (TR) format. Both use identical 8-SMD, Gull Wing surface mount packages. Tape & Reel format is standard for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both have MSL 1 (unlimited) moisture sensitivity rating.

Q: Are the switching characteristics equivalent?

A: Yes. Rise and fall times are identical (4µs and 3µs respectively). Current transfer ratio specifications, input type (AC/DC), and output type (transistor) are fully equivalent.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -30°C to 100°C, with identical Vce saturation maximum of 200mV and output current rating of 50mA per channel.
