MCT5200 Equivalent & Substitute Parts

Part Overview

The MCT5200 is an optoisolator transistor with base output manufactured by onsemi, rated for 5300Vrms isolation voltage in a 6-DIP package. This component provides galvanic isolation for single-channel DC input applications with transistor output capability. The MCT5200 is classified as obsolete, making identification of functionally equivalent substitute parts essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT5200 is determined by the following critical parameters:

• Isolation Voltage: Minimum 5300Vrms to maintain equivalent isolation performance
• Output Type: Transistor with Base configuration required for circuit compatibility
• Package / Case: 6-DIP (0.300", 7.62mm) for mechanical and electrical pin compatibility
• Mounting Type: Through Hole for PCB assembly compatibility
• Number of Channels: Single channel (1) configuration
• Input Type: DC input requirement
• Output Voltage & Current Ratings: Maximum 30V output, minimum 150mA per channel capability

Based on these criteria, the following parts qualify as substitutes:

Direct Substitutes (Matching All Critical Parameters):

• 4N35: onsemi, 5300Vrms isolation, transistor with base, 6-DIP package, through hole, obsolete status

Functional Substitutes (Meeting Core Requirements with Parameter Variations):

• 4N35-000E: Broadcom Limited, 3550Vrms isolation, transistor with base, 6-DIP package, through hole, active status
• MCT5210M: onsemi, 4170Vrms isolation, transistor with base, 6-DIP package, through hole, active status

Parameter Comparison

Engineering Selection Recommendations

4N35 (onsemi): This part matches the MCT5200 across all critical electrical and mechanical parameters, including isolation voltage, output type, and package configuration. Both parts share obsolete status. Selection of 4N35 provides direct functional equivalence with no parameter compromises.

4N35-000E (Broadcom Limited): This part maintains package and output type compatibility but operates at reduced isolation voltage (3550Vrms versus 5300Vrms). The 4N35-000E is active status and ROHS3 compliant, offering supply continuity advantages. Selection requires verification that the lower isolation voltage meets circuit requirements.

MCT5210M (onsemi): This part maintains onsemi manufacturer continuity and active product status with ROHS3 compliance. Isolation voltage is reduced to 4170Vrms, and minimum operating temperature is limited to -40°C (versus -55°C). Current transfer ratio is specified at lower input current (3mA versus 10mA). Selection requires confirmation that reduced isolation voltage and temperature range are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can MCT5210M replace MCT5200 in all applications?

A: MCT5210M shares the same package, output type, and maximum output ratings. However, isolation voltage is reduced from 5300Vrms to 4170Vrms, and the minimum operating temperature is -40°C instead of -55°C. Substitution is valid only if the application does not require the higher isolation voltage or lower temperature operation.

Q: What is the primary difference between 4N35 and 4N35-000E?

A: Both parts provide 5300Vrms isolation and 6-DIP package compatibility. The 4N35-000E is manufactured by Broadcom Limited (versus onsemi for 4N35), carries active product status, and is ROHS3 compliant. The 4N35-000E is the preferred choice for new designs requiring compliance documentation.

Q: Is the 4N35-000E suitable for high-isolation applications?

A: The 4N35-000E provides 3550Vrms isolation, which is lower than the MCT5200 specification of 5300Vrms. Applications requiring 5300Vrms isolation should use 4N35 or MCT5200. The 4N35-000E is suitable for applications with isolation requirements at or below 3550Vrms.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts (4N35, 4N35-000E, and MCT5210M) are supplied in 6-DIP (0.300", 7.62mm) through-hole packages, ensuring direct PCB compatibility with MCT5200 designs without layout modifications.

Q: Which substitute part offers the best long-term supply availability?

A: MCT5210M and 4N35-000E both carry active product status, indicating ongoing manufacturing and supply availability. The 4N35 and MCT5200 are both obsolete. For new designs or long-term production, MCT5210M (onsemi) or 4N35-000E (Broadcom Limited) are recommended.
