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)
• RoHS Status: ROHS3 Compliant (identical)

The primary difference is the Number of Channels: ACPL-5731L provides 2 channels, while ACPL-5700L provides 1 channel. This distinction determines application suitability based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both ACPL-5731L and ACPL-5700L maintain Active product status from Broadcom Limited and are ROHS3 Compliant. Selection between these parts depends on circuit channel requirements: use ACPL-5731L for dual-channel isolation applications and ACPL-5700L for single-channel isolation applications. Both parts share identical electrical performance characteristics including isolation voltage, current transfer ratio, output voltage rating, and output current per channel. The 8-CDIP package and through-hole mounting type are consistent across both variants, ensuring mechanical compatibility in PCB layouts designed for either part.

Frequently Asked Questions (FAQ)

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

A: ACPL-5700L can replace ACPL-5731L only in applications requiring single-channel isolation. The ACPL-5700L provides 1 channel while ACPL-5731L provides 2 channels. Circuit design must accommodate this channel difference.
