Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACPL-573KL-200 are identified based on the following critical parameters that determine functional equivalence:

• Voltage - Isolation: 1500VDC
• Output Type: Darlington
• Current Transfer Ratio (Min): 200% @ 5mA
• Voltage - Output (Max): 20V
• Current - Output / Channel: 40mA
• Package / Case: 8-CDIP (0.300", 7.62mm)
• Operating Temperature: -55°C ~ 125°C

The ACPL-5700L is identified as a parametric equivalent. While it differs in channel count (1 channel vs. 2 channels), it maintains all critical electrical parameters and physical packaging specifications. This substitution is valid for applications requiring single-channel isolation with identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the ACPL-573KL-200 and ACPL-5700L are active products from Broadcom Limited with identical electrical performance specifications. The primary distinction is channel count: the ACPL-573KL-200 provides 2 channels while the ACPL-5700L provides 1 channel in the same physical package.

The ACPL-5700L carries ROHS3 compliance, whereas the ACPL-573KL-200 is RoHS non-compliant. For applications subject to RoHS requirements, the ACPL-5700L is the appropriate selection. For single-channel isolation requirements with identical electrical characteristics, the ACPL-5700L provides a direct functional substitute.

Frequently Asked Questions (FAQ)

Q: Can the ACPL-5700L replace the ACPL-573KL-200 in all applications?

A: The ACPL-5700L is a functional substitute only for applications requiring single-channel isolation. The ACPL-573KL-200 provides 2 channels in a single package. If your design requires dual-channel isolation, the ACPL-5700L cannot serve as a direct replacement without circuit redesign.

Q: Are the electrical parameters identical between these parts?

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

Q: What is the difference in RoHS compliance?

A: The ACPL-573KL-200 is RoHS non-compliant. The ACPL-5700L is ROHS3 compliant. For applications requiring RoHS compliance, the ACPL-5700L is the appropriate selection.

Q: Are both parts available in the same package?

A: Yes. Both parts use the 8-CDIP (0.300", 7.62mm) through-hole package with identical pinout compatibility for their respective channel configurations.

Q: What inventory levels are available?

A: The ACPL-573KL-200 has 775 units in stock. The ACPL-5700L has 1173 units in stock.
