Key Parameters

Substitute Part Grouping Explanation

The ACPL-5700L qualifies as a parametric equivalent based on the following critical parameters:

• Voltage - Isolation: 1500VDC (identical)
• Current Transfer Ratio (Min): 200% @ 5mA (identical)
• Output Type: Darlington (identical)
• Voltage - Output (Max): 20V (identical)
• Current - Output / Channel: 40mA (identical)
• Operating Temperature: -55°C ~ 125°C (identical)
• Package / Case: 8-CDIP (0.300", 7.62mm) (identical)
• Mounting Type: Through Hole (identical)
• Turn On / Turn Off Time (Typ): 2µs, 6µs (identical)
• Input Type: DC (identical)

The primary difference is the channel count: ACPL-5731L-200 provides 2 channels, while ACPL-5700L provides 1 channel. This substitution is valid only for applications requiring single-channel isolation.

Parameter Comparison

Engineering Selection Recommendations

The ACPL-5700L is a valid substitute for the ACPL-5731L-200 in single-channel isolation applications. The ACPL-5700L offers improved compliance status with ROHS3 certification, whereas the ACPL-5731L-200 is RoHS non-compliant. Both parts maintain identical electrical performance characteristics for isolation voltage, current transfer ratio, output voltage, and operating temperature range. Selection between these parts depends on application channel requirements and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can ACPL-5700L replace ACPL-5731L-200 in all applications?

A: No. The ACPL-5700L is a single-channel device, while the ACPL-5731L-200 is dual-channel. Substitution is valid only for applications requiring one isolation channel.

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts share identical isolation voltage (1500VDC), current transfer ratio (200% @ 5mA), output voltage rating (20V), per-channel output current (40mA), and operating temperature range (-55°C ~ 125°C).

Q: What is the difference in RoHS compliance?

A: The ACPL-5731L-200 is RoHS non-compliant, while the ACPL-5700L is ROHS3 compliant. Applications subject to RoHS regulations should use the ACPL-5700L.

Q: Are both parts available in the same package?

A: Yes. Both parts use the 8-CDIP (0.300", 7.62mm) package with through-hole mounting, ensuring identical PCB footprint compatibility.

Q: What are the turn-on and turn-off times for these optoisolators?

A: Both parts have identical switching characteristics: 2µs turn-on time and 6µs turn-off time (typical).
