FOD2200 Equivalent & Substitute Parts

Part Overview

The FOD2200 is a logic output optoisolator manufactured by onsemi, featuring 5000Vrms isolation voltage, tri-state output configuration, and 2.5MBd data rate in an 8-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The FOD2200 provides galvanic isolation for digital logic signals with high common mode transient immunity of 10kV/µs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FOD2200 is determined by the following critical parameters: single-channel configuration, tri-state output type, 8-DIP through-hole package, and operating temperature range of -40°C to 85°C. All substitute parts must maintain these core characteristics.

The isolation voltage and common mode transient immunity define two substitution categories:

Category A - Full Electrical Equivalence: Parts maintaining 5000Vrms isolation voltage and minimum 10kV/µs CMTI. The EL2200 qualifies under this category, offering enhanced performance with 5MBd data rate while preserving the critical isolation and transient immunity specifications.

Category B - Reduced Isolation Voltage: Parts with 3750Vrms isolation voltage and 1kV/µs CMTI. The HCPL-2200 and HCPL-2200-000E fall into this category. These parts are suitable for applications where the lower isolation voltage and reduced transient immunity are acceptable within system design margins.

Parameter Comparison

Engineering Selection Recommendations

EL2200 (Everlight Electronics Co Ltd): This substitute maintains full electrical equivalence with 5000Vrms isolation voltage and is the preferred choice for applications requiring the original FOD2200 performance specifications. The EL2200 offers enhanced data rate capability at 5MBd and is ROHS3 compliant. Product status is active with confirmed inventory availability.

HCPL-2200 and HCPL-2200-000E (Broadcom Limited): These substitutes operate at reduced isolation voltage of 3750Vrms and lower common mode transient immunity of 1kV/µs. Selection of these parts is appropriate only when system design margins accommodate the reduced isolation specifications. The HCPL-2200-000E variant is ROHS3 compliant, while the HCPL-2200 is RoHS non-compliant. Both maintain active product status with adequate inventory.

For new designs replacing obsolete FOD2200 inventory, the EL2200 provides direct functional replacement. The HCPL-2200 variants require circuit-level evaluation to confirm compatibility with reduced isolation and transient immunity parameters.

Frequently Asked Questions (FAQ)

Q: Can the EL2200 directly replace the FOD2200 in existing designs?

A: The EL2200 maintains identical isolation voltage (5000Vrms), output type (tri-state), package (8-DIP), and operating temperature range. Pin-level compatibility and circuit behavior are equivalent. The EL2200 offers superior data rate performance at 5MBd compared to the FOD2200's 2.5MBd.

Q: What are the key differences between the EL2200 and HCPL-2200 substitutes?

A: The EL2200 maintains 5000Vrms isolation voltage and 10kV/µs CMTI, matching the original FOD2200 specifications. The HCPL-2200 variants operate at 3750Vrms isolation with 1kV/µs CMTI. Selection depends on whether your application requires the higher isolation voltage and transient immunity of the original design.

Q: Are all substitute parts available in the same 8-DIP package?

A: Yes. The FOD2200, EL2200, HCPL-2200, and HCPL-2200-000E are all supplied in 8-DIP (0.300", 7.62mm) through-hole packages, ensuring mechanical compatibility on existing PCBs.

Q: What is the difference between HCPL-2200 and HCPL-2200-000E?

A: Both parts are electrically identical with 3750Vrms isolation and 2.5MBd data rate. The primary difference is RoHS compliance: HCPL-2200-000E is ROHS3 compliant, while HCPL-2200 is RoHS non-compliant. For new designs, HCPL-2200-000E is the preferred variant.

Q: Can I use HCPL-2200 variants if my application originally used FOD2200?

A: HCPL-2200 variants are suitable only if your circuit design accommodates 3750Vrms isolation voltage and 1kV/µs common mode transient immunity. Applications requiring the full 5000Vrms isolation and 10kV/µs CMTI of the original FOD2200 must use the EL2200 substitute.

Q: What supply voltage range do these optoisolators support?

A: The FOD2200, HCPL-2200, and HCPL-2200-000E support 4.5V to 20V supply voltage. The EL2200 operates at a fixed 20V supply, which may require circuit modification if your design uses variable supply voltages below 20V.
