ACPL-4800-500E Equivalent & Substitute Parts

Part Overview

The ACPL-4800-500E is a logic output optoisolator with push-pull totem pole configuration manufactured by Broadcom Limited. This device provides 3750Vrms isolation with 1 channel, designed for applications requiring galvanic isolation in digital signal transmission. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance can be maintained within the allowed parameter tolerances for this optoisolator category, particularly when packaging constraints or supply availability necessitate alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACPL-4800-500E are qualified based on the following critical parameters that define functional equivalence within the optoisolator category:

Core Electrical Compatibility Criteria:

• Number of Channels: 1 (must match)
• Output Type: Push-Pull, Totem Pole (must match)
• Current - Output / Channel: 25 mA (must match)
• Propagation Delay tpLH / tpHL (Max): 350ns, 350ns (must match)
• Voltage - Supply: 4.5V ~ 20V (must match)
• Operating Temperature: -40°C ~ 100°C (must match)
• Input Type: DC (must match)
• Manufacturer: Broadcom Limited (must match)
• Product Status: Active (must match)
• RoHS Status: ROHS3 Compliant (must match)

Parameters Allowed to Vary:

• Voltage - Isolation: 3750Vrms or higher
• Common Mode Transient Immunity (Min): 20kV/µs or higher
• Package / Case: Alternative surface mount packages acceptable
• Packaging Type: Tape & Reel (TR), Cut Tape (CT), or Digi-Reel®

The ACPL-4800-500E has two manufacturer-recommended substitutes that maintain electrical performance while offering different isolation ratings and package configurations.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory compliance across current and future applications.

ACPL-4800-500E (Primary Part): 8-DIP Gull Wing package with 3750Vrms isolation and 30kV/µs CMTI. Select this configuration when the 8-pin DIP footprint is required and maximum common mode transient immunity is specified.

ACPL-P480-500E (Substitute - Compact Package): 6-SOIC package with 3750Vrms isolation and 20kV/µs CMTI. This substitute provides equivalent isolation voltage with reduced pin count and smaller footprint. The forward voltage increases from 1.5V to 1.7V. Select when board space is constrained and 20kV/µs CMTI meets application requirements.

ACPL-W480-500E (Substitute - Enhanced Isolation): 6-SOIC Stretched package with 5000Vrms isolation and 20kV/µs CMTI. This substitute provides higher isolation voltage rating with the same reduced pin count. The forward voltage is 1.7V. Select when applications require isolation voltage exceeding 3750Vrms or when using the stretched SOIC footprint.

Frequently Asked Questions (FAQ)

Q: Can ACPL-P480-500E replace ACPL-4800-500E in all applications?

A: ACPL-P480-500E maintains electrical equivalence for propagation delay, output current, supply voltage, and operating temperature. The primary differences are package configuration (6-SOIC vs. 8-DIP), reduced CMTI (20kV/µs vs. 30kV/µs), and increased forward voltage (1.7V vs. 1.5V). Substitution is valid when the application PCB layout accommodates the 6-SOIC footprint and the 20kV/µs CMTI specification is acceptable.

Q: What is the difference between ACPL-P480-500E and ACPL-W480-500E?

A: Both parts use the 6-SOIC package and share 20kV/µs CMTI. The primary difference is isolation voltage: ACPL-P480-500E provides 3750Vrms while ACPL-W480-500E provides 5000Vrms. The ACPL-W480-500E uses a stretched SOIC footprint (6.80mm width vs. 4.58mm width). Select ACPL-W480-500E when higher isolation voltage is required or when the stretched package footprint is available on the PCB.

Q: Are all three parts suitable for high-speed digital isolation applications?

A: All three parts maintain identical propagation delay specifications (350ns maximum for both rising and falling edges) and identical rise/fall times (16ns and 20ns typical). They are functionally equivalent for timing-critical applications. Package selection should be based on PCB layout constraints and isolation voltage requirements.

Q: What compliance certifications apply to these substitute parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. They are suitable for applications requiring regulatory compliance in current and future product generations.

Q: Can forward voltage differences affect circuit design?

A: The ACPL-4800-500E has 1.5V typical forward voltage, while ACPL-P480-500E and ACPL-W480-500E have 1.7V typical forward voltage. This 0.2V difference may affect LED drive current calculations in the input stage. Verify that input current limiting resistor values remain within acceptable ranges for the substitute part's forward voltage specification.
