• Input Type: DC
• 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
• Mounting Type: Through Hole
• Package / Case: 8-CDIP (0.300", 7.62mm)

The ACPL-5700L meets all electrical and mechanical parameters specified for the ACPL-570KL-200, making it a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ACPL-570KL-200 and ACPL-5700L are active production parts from Broadcom Limited with identical electrical and mechanical specifications. The primary distinction between these parts is regulatory compliance status. The ACPL-570KL-200 is RoHS non-compliant, while the ACPL-5700L is ROHS3 compliant. Both parts maintain REACH Unaffected status and identical EAR99 export classification.

Selection between these parts should be based on end-use application requirements and regional regulatory mandates. Applications subject to RoHS3 compliance requirements must use the ACPL-5700L. Applications without RoHS3 compliance requirements may use either part based on availability and supply chain considerations. Both parts are functionally interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Are the ACPL-570KL-200 and ACPL-5700L pin-compatible?

A: Yes. Both parts use identical 8-DIP through-hole packaging with 0.300" (7.62mm) spacing. Pin configuration and functional assignment are identical, enabling direct socket substitution.

Q: What is the primary difference between these two parts?

A: The ACPL-5700L is ROHS3 compliant, while the ACPL-570KL-200 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Can I substitute the ACPL-5700L for the ACPL-570KL-200 in existing designs?

A: Yes, the ACPL-5700L is a parametric equivalent and can be substituted directly. No circuit modifications are required.

Q: Can I substitute the ACPL-570KL-200 for the ACPL-5700L?

A: Substitution is possible from an electrical and mechanical standpoint. However, if the application or end market requires RoHS3 compliance, the ACPL-570KL-200 does not meet this requirement.

Q: What does the "KL" designation in ACPL-570KL-200 indicate?

A: The designation is part of the manufacturer's part numbering scheme. The ACPL-5700L uses a different designation structure but maintains identical functional specifications.

Q: Are both parts available in the same packaging options?

A: Both parts are supplied in 8-DIP tube packaging. No alternative packaging options are specified for either part.

Q: What is the isolation voltage rating for these optoisolators?

A: Both parts are rated for 1500VDC isolation voltage, suitable for high-voltage galvanic isolation applications.

Q: What is the maximum output current for these parts?

A: Both parts support a maximum output current of 40mA per channel. Single-channel configuration limits total output current to this value.
