MCT52013S Equivalent & Substitute Parts

Part Overview

The MCT52013S 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 with transistor output and integrated base connection, suitable for DC input applications. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT52013S is determined by the following critical parameters:

• Isolation Voltage Rating: Minimum 5300Vrms required for equivalent isolation performance
• Output Configuration: Transistor with base output mandatory for circuit compatibility
• Number of Channels: Single channel requirement
• Package Type: 6-SMD, Gull Wing surface mount configuration
• Output Voltage & Current Ratings: Maximum 30V output, 150mA per channel minimum
• Vce Saturation: Maximum 400mV specification
• Input Type: DC input requirement
• Operating Temperature Range: Must support -55°C to 100°C minimum

The MCT5210SM from Fairchild Semiconductor meets the core functional requirements of output type, package configuration, and electrical ratings. However, the isolation voltage rating of 4170Vrms is below the MCT52013S specification of 5300Vrms, and the operating temperature range is limited to -40°C ~ 100°C, restricting its use to applications not requiring the full lower temperature performance of the original part.

Parameter Comparison

Engineering Selection Recommendations

The MCT52013S is obsolete and no longer available from the original manufacturer. The MCT5210SM provides functional compatibility for applications where the reduced isolation voltage rating of 4170Vrms is acceptable and operating temperatures do not require performance below -40°C.

For applications requiring the full 5300Vrms isolation specification or extended low-temperature operation to -55°C, alternative optoisolator transistor with base output components from active product lines must be evaluated against the complete parameter set. The MCT5210SM is currently in active production status, ensuring supply chain availability for new implementations within its specified parameter limits.

Frequently Asked Questions (FAQ)

Q: Can MCT5210SM directly replace MCT52013S in all applications?

A: No. The MCT5210SM has a lower isolation voltage rating (4170Vrms vs. 5300Vrms) and a narrower operating temperature range (-40°C to 100°C vs. -55°C to 100°C). Substitution is only valid for applications that do not require these higher specifications.

Q: What are the key differences between these two parts?

A: The primary differences are isolation voltage rating, operating temperature range, and current transfer ratio specifications. Both parts share identical package configuration, output voltage/current ratings, and Vce saturation characteristics.

Q: Are the packages physically identical?

A: Yes. Both MCT52013S and MCT5210SM use 6-SMD, Gull Wing surface mount packages, allowing for direct PCB footprint compatibility.

Q: What should I do if my application requires 5300Vrms isolation?

A: The MCT5210SM cannot be used. Consult the active optoisolator product lines from onsemi, Fairchild Semiconductor, or other manufacturers for components meeting the full 5300Vrms isolation specification.

Q: Is the MCT5210SM suitable for low-temperature applications below -40°C?

A: No. The MCT5210SM operating temperature range begins at -40°C. For applications requiring operation at -55°C, the original MCT52013S specification or alternative components with extended low-temperature ratings must be used.
