• Number of Channels: 1
• Voltage - Isolation: 1500VDC
• Current Transfer Ratio (Min): 200% @ 5mA
• Turn On / Turn Off Time (Typ): 2µs, 6µs
• Output Type: Darlington
• Voltage - Output (Max): 20V
• Current - Output / Channel: 40mA
• Voltage - Forward (Vf) (Typ): 1.4V
• Current - DC Forward (If) (Max): 10 mA
• Operating Temperature: -55°C ~ 125°C
• Package / Case: 8-CDIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The ACPL-5700L is a parametric equivalent substitute for the ACPL-570KL. Both components are manufactured by Broadcom Limited and maintain identical electrical and mechanical specifications across all critical parameters. Both parts carry Active product status, ROHS3 compliance certification, and unlimited moisture sensitivity rating (MSL 1). Selection between these parts may be based on inventory availability or supply chain considerations, as no technical differentiation exists between the two models.

Frequently Asked Questions (FAQ)

Q: Can ACPL-5700L be used as a direct replacement for ACPL-570KL?

A: Yes. The ACPL-5700L meets all parametric requirements for direct substitution. Electrical performance, isolation voltage, output characteristics, timing specifications, and package configuration are identical. Both components are rated for the same operating temperature range and carry equivalent compliance certifications.

Q: Are there any package or pinout differences between these parts?

A: No. Both the ACPL-570KL and ACPL-5700L use the 8-CDIP (0.300", 7.62mm) package with through-hole mounting. Pinout and mechanical dimensions are identical, enabling direct PCB compatibility.

Q: What are the key parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: isolation voltage (1500VDC), number of channels (1), current transfer ratio (200% @ 5mA), output type (Darlington), maximum output voltage (20V), output current per channel (40mA), forward voltage (1.4V), maximum forward current (10mA), operating temperature range (-55°C to 125°C), and package type (8-CDIP).

Q: Do both parts have the same compliance certifications?

A: Yes. Both ACPL-570KL and ACPL-5700L are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.
