MCT2200 Equivalent & Substitute Parts

Part Overview

The MCT2200 is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 5300Vrms isolation rating. This component features a single channel configuration in a 6-DIP package and is rated for DC input with transistor output including base connection. The MCT2200 is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT2200 optoisolator is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use 6-DIP (0.300", 7.62mm) through-hole mounting to ensure direct board-level compatibility without layout modifications.

Output Configuration: The substitute must provide transistor output with base connection, maintaining the same control interface and signal characteristics.

Isolation Voltage: The substitute's isolation voltage rating must meet or exceed the application requirement. The MCT2200 specifies 5300Vrms isolation.

Input/Output Electrical Characteristics: Current transfer ratio, output voltage rating, output current capability, and saturation voltage must be compatible with the circuit design parameters.

Operating Temperature Range: The substitute must support the full operating temperature range of -55°C to 100°C.

Input Type: DC input configuration must be maintained.

Based on these criteria, the 4N25-000E from Broadcom Limited is identified as a substitute part, though with specific parameter trade-offs documented in the comparison table below.

Engineering Selection Recommendations

The MCT2200 is obsolete, necessitating alternative component identification for new procurement and design continuity.

The 4N25-000E is an active product from Broadcom Limited and maintains package and functional compatibility with the MCT2200. Both components share identical 6-DIP through-hole packaging, single-channel configuration, transistor-with-base output topology, and operating temperature range.

Key Differences:

The 4N25-000E has a lower isolation voltage rating of 2500Vrms compared to the MCT2200's 5300Vrms. This substitution is valid only for applications where the circuit isolation requirement does not exceed 2500Vrms.

The 4N25-000E provides higher output current capability (100mA versus 50mA) and lower forward voltage drop (1.2V typical versus 1.25V typical), offering improved performance in output drive applications.

The 4N25-000E exhibits higher Vce saturation (500mV maximum versus 400mV maximum), which may impact switching efficiency in low-voltage output stages.

The 4N25-000E is ROHS3 compliant, supporting modern supply chain and environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 4N25-000E directly replace the MCT2200 in all applications?

A: Direct replacement is possible only if the circuit isolation voltage requirement does not exceed 2500Vrms. The MCT2200 provides 5300Vrms isolation, which is higher than the 4N25-000E. Applications requiring the full 5300Vrms isolation rating cannot use the 4N25-000E as a substitute.

Q: Are the 6-DIP packages identical between MCT2200 and 4N25-000E?

A: Both components use 6-DIP (0.300", 7.62mm) through-hole packaging. Pin-to-pin compatibility is maintained, allowing direct board-level substitution without layout modifications.

Q: What are the differences in switching speed between these parts?

A: The MCT2200 specifies turn-on and turn-off times of 2µs each. The 4N25-000E specifies rise and fall times of 3µs each. These timing parameters are measured under different conditions and are not directly comparable, but the 4N25-000E exhibits slightly slower switching characteristics.

Q: Does the higher output current of the 4N25-000E affect circuit design?

A: The 4N25-000E provides 100mA output current capability versus the MCT2200's 50mA. This higher capability does not negatively affect circuits designed for the MCT2200, as the 4N25-000E can supply equal or greater current without modification.

Q: What compliance certifications apply to each part?

A: The 4N25-000E is ROHS3 compliant. Both parts are REACH unaffected and classified under ECCN EAR99 for export control purposes.

Q: Are there inventory considerations for these parts?

A: The MCT2200 is obsolete with 4200 pieces available in current inventory. The 4N25-000E is an active product with 3000 pieces in stock, providing ongoing availability for future procurement.
