ACPL-072L Equivalent & Substitute Parts

Part Overview

The ACPL-072L is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 3750Vrms isolation device operates at 25MBd with push-pull totem pole output configuration, housed in an 8-SO package. The component is currently in active product status with 1551 units in stock.

Substitute parts are identified to address supply chain requirements, alternative sourcing needs, or specific packaging and compliance preferences while maintaining electrical and mechanical compatibility within the defined parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACPL-072L is determined by the following critical parameters:

Mandatory Matching Parameters:

• Isolation Voltage: 3750Vrms
• Output Type: Push-Pull, Totem Pole
• Current - Output / Channel: 10 mA
• Number of Channels: 1
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Allowable Parameter Variations:

• Data Rate: Substitute parts may operate at 12.5Mbps or 25Mbps (equal or higher than 12.5Mbps minimum)
• Common Mode Transient Immunity: Substitute parts may exceed 10kV/µs minimum
• Propagation Delay: Substitute parts must not exceed 40ns maximum
• Voltage - Supply: Substitute parts must support 4.5V ~ 5.5V range (ACPL-072L's dual-supply capability is not required)
• Operating Temperature: Substitute parts must support -40°C minimum and 100°C or higher maximum

Identified substitute parts meet all mandatory parameters and fall within allowable variations for optional parameters.

Parameter Comparison

Engineering Selection Recommendations

FOD0720 and FOD0720R2 (Fairchild Semiconductor): These parts match the ACPL-072L data rate specification at 25Mbps and provide equivalent propagation delay performance. Both are active products with high inventory availability (5394 and 3720 units respectively). FOD0720R2 is supplied in Tape & Reel packaging, suitable for automated assembly processes.

FOD0721 and FOD0721R2 (onsemi): These parts operate at 25Mbps, matching the ACPL-072L performance tier. Both are ROHS3 compliant and active products. FOD0721R2 is supplied in Tape & Reel format with 3820 units in stock. FOD0721 is available in Tube packaging with 1923 units in stock.

FOD0710 and FOD0710R2 (Fairchild Semiconductor / onsemi): These parts operate at 12.5Mbps, representing a lower data rate tier. FOD0710R2 (onsemi) is ROHS3 compliant and supplied in Tape & Reel format with 3620 units available. Both maintain the required propagation delay specification and are active products.

FOD8001 (Fairchild Semiconductor): Insufficient parameter data is provided for this part. Complete electrical specifications are required to confirm substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can FOD0710 or FOD0710R2 replace ACPL-072L in all applications?

A: FOD0710 and FOD0710R2 operate at 12.5Mbps, which is half the data rate of the ACPL-072L (25MBd). These parts are suitable only for applications where the lower data rate meets system requirements. All other electrical parameters, isolation voltage, output type, and package dimensions are compatible.

Q: What is the difference between FOD0720 and FOD0720R2?

A: FOD0720 and FOD0720R2 are electrically identical, both manufactured by Fairchild Semiconductor at 25Mbps. The designation difference reflects internal revision levels. Both are active products with equivalent performance specifications.

Q: Are FOD0721 and FOD0721R2 interchangeable?

A: FOD0721 and FOD0721R2 are electrically identical onsemi products at 25Mbps. The primary difference is packaging: FOD0721 is supplied in Tube format, while FOD0721R2 is supplied in Tape & Reel format. Selection depends on assembly process requirements.

Q: Does the ACPL-072L's dual supply voltage range (3V ~ 3.6V, 4.5V ~ 5.5V) affect substitute part selection?

A: All identified substitute parts support the 4.5V ~ 5.5V supply range. If the application requires operation in the 3V ~ 3.6V range, the ACPL-072L must be retained, as substitute parts do not support this lower voltage tier.

Q: What is the significance of CMTI (Common Mode Transient Immunity) differences?

A: The ACPL-072L specifies 10kV/µs minimum CMTI. All substitute parts exceed this specification at 20kV/µs, providing enhanced noise immunity. This represents an improvement over the original part and does not create compatibility issues.

Q: Is FOD8001 a valid substitute for ACPL-072L?

A: FOD8001 cannot be confirmed as a substitute due to incomplete parameter specification in available data. Critical electrical parameters including data rate, propagation delay, and operating temperature range are not provided. Complete datasheet review is required before consideration.

Q: How do packaging options affect component selection?

A: Packaging format (Bulk, Tape & Reel, Tube) does not affect electrical performance or PCB-level compatibility. Selection is based on manufacturing process requirements: Tape & Reel format is standard for automated pick-and-place assembly, while Bulk and Tube formats are suitable for manual or semi-automated processes.
