FOD2200T Equivalent & Substitute Parts

Part Overview

The FOD2200T is a logic output optoisolator manufactured by onsemi, designed for high-speed digital isolation applications requiring 5000Vrms isolation voltage. This component features tri-state output capability, 2.5MBd data rate, and 10kV/µs common mode transient immunity in an 8-MDIP package. The FOD2200T is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FOD2200T is evaluated based on the following critical parameters that define functional equivalence for logic output optoisolators:

• Number of Channels: Must be 1 channel
• Output Type: Must be tri-state
• Data Rate: Must support 2.5MBd minimum
• Voltage - Supply: Must operate within 4.5V ~ 20V range
• Operating Temperature: Must support -40°C ~ 85°C range
• Mounting Type: Must be through-hole compatible
• Package Compatibility: Pin count and footprint must accommodate 8-pin DIP configuration

The HCPL-2200-000E from Broadcom Limited meets these functional requirements. While the isolation voltage (3750Vrms) is lower than the FOD2200T (5000Vrms) and the CMTI specification (1kV/µs) is reduced compared to the original (10kV/µs), the substitute maintains all critical operational parameters including tri-state output, 2.5MBd data rate, 25mA output current, and identical supply voltage range.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2200-000E is an active product with ROHS3 compliance, providing supply chain continuity for applications currently using the obsolete FOD2200T. Both components share identical data rate, output current, supply voltage range, and operating temperature specifications.

Selection between FOD2200T and HCPL-2200-000E depends on application-specific isolation voltage and CMTI requirements. Applications requiring 5000Vrms isolation or 10kV/µs CMTI performance must retain FOD2200T inventory or identify alternative components meeting these specifications. Applications tolerating 3750Vrms isolation and 1kV/µs CMTI can transition to HCPL-2200-000E.

Package footprint differences exist: FOD2200T uses 0.400" (10.16mm) spacing while HCPL-2200-000E uses 0.300" (7.62mm) spacing. PCB layout modifications may be required for physical substitution.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2200-000E directly replace FOD2200T in existing designs?

A: Direct replacement requires verification that application isolation voltage requirements do not exceed 3750Vrms and CMTI performance tolerance does not require 10kV/µs. PCB footprint differences (0.400" vs 0.300" DIP spacing) necessitate layout evaluation.

Q: What are the key differences between these optoisolators?

A: The primary differences are isolation voltage (5000Vrms vs 3750Vrms), CMTI specification (10kV/µs vs 1kV/µs), and DIP package pitch (0.400" vs 0.300"). All other functional parameters including data rate, output current, and operating temperature are identical.

Q: Is HCPL-2200-000E suitable for high-speed isolation applications?

A: Both components support 2.5MBd data rate with identical 300ns propagation delay specifications. HCPL-2200-000E is suitable for applications within its 3750Vrms isolation and 1kV/µs CMTI ratings.

Q: What compliance certifications apply to these parts?

A: FOD2200T carries REACH Unaffected and EAR99 classifications. HCPL-2200-000E is ROHS3 compliant with identical REACH and ECCN status.

Q: Are there package compatibility considerations?

A: Both use 8-DIP through-hole packages but with different pitch specifications. Verify PCB pad spacing compatibility before physical substitution.
