MCT5210 Equivalent & Substitute Parts

Part Overview

The MCT5210 is an optoisolator transistor with base output manufactured by Vishay Semiconductor Opto Division. This component provides galvanic isolation up to 5300Vrms with a single channel configuration in a 6-DIP package. The device is designed for applications requiring high-voltage isolation with transistor output capability and integrated base connection for enhanced control. The MCT5210 maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications requiring long-term availability and environmental compliance.

Alternative models become necessary when addressing specific application requirements such as higher output voltage ratings, increased output current capacity, or improved switching characteristics that may better match system design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCT5210 is evaluated based on the following critical parameters that define functional equivalence:

Isolation Voltage: The MCT5210 provides 5300Vrms isolation. Substitute parts must maintain isolation voltage at or above 5000Vrms to ensure equivalent or superior galvanic separation capability.

Package Configuration: Both the main part and substitutes must use 6-DIP (0.300", 7.62mm) through-hole mounting to ensure direct pin-compatible replacement without PCB redesign.

Output Type: The transistor with base output configuration must be preserved to maintain control characteristics and circuit compatibility.

Operating Temperature Range: The -55°C ~ 100°C range must be supported to ensure operation across the specified environmental conditions.

Compliance Standards: RoHS3 compliance and EAR99 ECCN classification must be maintained for regulatory and export consistency.

The CNY17-3-000E from Broadcom Limited qualifies as a substitute based on these parameters, offering comparable isolation voltage (5000Vrms), identical package format, matching output type, and equivalent temperature range with full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the MCT5210 and CNY17-3-000E maintain Active product status with full RoHS3 compliance and EAR99 ECCN classification, ensuring regulatory consistency and long-term supply availability. The MCT5210 provides higher isolation voltage (5300Vrms versus 5000Vrms), while the CNY17-3-000E offers enhanced output voltage capability (70V versus 30V), lower saturation voltage (300mV versus 400mV), and specified output current rating (150mA). Selection between these parts depends on whether the application prioritizes maximum isolation voltage or requires higher output voltage and current specifications. Both components support the full -55°C ~ 100°C operating temperature range and use identical 6-DIP through-hole packaging, enabling direct substitution at the board level.

Frequently Asked Questions (FAQ)

Q: Can the CNY17-3-000E directly replace the MCT5210 on existing PCBs?

A: Yes. Both components use identical 6-DIP (0.300", 7.62mm) through-hole packaging with matching pin configurations for transistor output with base connection. No PCB modification is required for physical replacement.

Q: What is the isolation voltage difference between these parts?

A: The MCT5210 provides 5300Vrms isolation, while the CNY17-3-000E provides 5000Vrms. Both exceed 5000Vrms minimum isolation requirements. The MCT5210 offers 300Vrms additional margin if maximum isolation voltage is a critical design parameter.

Q: Does the CNY17-3-000E offer performance advantages?

A: The CNY17-3-000E provides higher maximum output voltage (70V versus 30V), lower saturation voltage (300mV versus 400mV), and specified output current capability (150mA). These characteristics may improve performance in applications requiring higher output voltage swing or current delivery.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the MCT5210 and CNY17-3-000E are RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1), meeting environmental and regulatory requirements for industrial applications.

Q: What is the operating temperature range for both components?

A: Both parts operate across -55°C ~ 100°C, ensuring compatibility across industrial and commercial temperature specifications.

Q: Are there differences in current transfer ratio specifications?

A: Yes. The MCT5210 specifies 70% minimum CTR at 3mA input current, while the CNY17-3-000E specifies 100% minimum CTR at 10mA input current with 200% maximum at the same current level. Application input current requirements determine which specification is more suitable.
