MCT2ES1(TA) Equivalent & Substitute Parts

Part Overview

The MCT2ES1(TA) is an optoisolator transistor with base output manufactured by Everlight Electronics Co Ltd. This component provides galvanic isolation up to 5000Vrms with a single channel configuration in a 6-SMD surface mount package. The device is classified as Active product status with full RoHS3 compliance and MSL Level 1 rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across isolation voltage, switching characteristics, output voltage ratings, and package specifications. The MCT2ESM from Fairchild Semiconductor represents an available alternative with enhanced isolation voltage performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT2ES1(TA) is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Number of Channels: Must equal 1
• Output Type: Must be Transistor with Base
• Package / Case: Must be 6-SMD, Gull Wing
• Mounting Type: Must be Surface Mount
• Input Type: Must be DC
• Vce Saturation (Max): Must not exceed 400mV
• Current Transfer Ratio (Min): Must meet or exceed 20% @ 10mA

Performance Enhancement Parameters:

• Voltage - Isolation: Substitute may exceed 5000Vrms (higher isolation is acceptable)
• Voltage - Output (Max): Substitute may be lower than 80V (conservative design acceptable)
• Operating Temperature Range: Substitute range may be narrower than -55°C ~ 110°C
• Turn On / Turn Off Time: Substitute may be faster (lower values acceptable)

The MCT2ESM meets all mandatory criteria while providing enhanced isolation voltage at 7500Vpk and improved switching speed characteristics.

Frequently Asked Questions (FAQ)

Q: Can MCT2ESM directly replace MCT2ES1(TA) in all applications?

A: Direct replacement is possible only when the application does not require the full -55°C to 110°C operating temperature range and the output voltage requirement does not exceed 30V. The MCT2ESM provides enhanced isolation voltage and faster switching characteristics, making it suitable for most standard applications within its specified temperature range.

Q: What is the difference between 5000Vrms and 7500Vpk isolation ratings?

A: The MCT2ES1(TA) specifies 5000Vrms (root mean square AC voltage), while the MCT2ESM specifies 7500Vpk (peak voltage). These represent different measurement standards for isolation voltage. The MCT2ESM provides higher isolation capability, which is beneficial for high-voltage applications but not required for designs already qualified to 5000Vrms.

Q: Are the 6-SMD packages identical between both parts?

A: Both parts use 6-SMD, Gull Wing surface mount packages. Mechanical compatibility is confirmed for PCB footprint and reflow soldering processes. No package redesign is required for substitution.

Q: What is the impact of the narrower operating temperature range in MCT2ESM?

A: The MCT2ESM operates from -40°C to 100°C compared to MCT2ES1(TA) at -55°C to 110°C. Applications requiring operation below -40°C or above 100°C must use the MCT2ES1(TA). Standard industrial and commercial temperature range applications (-40°C to 85°C) are fully supported by both parts.

Q: How do the switching times compare?

A: MCT2ESM provides faster switching with 2µs turn-on/turn-off time and 2µs/1.5µs rise/fall time compared to MCT2ES1(TA) at 3µs for all parameters. This improvement allows MCT2ESM to support higher frequency switching applications.

Q: What is the significance of the 80V vs 30V output voltage rating difference?

A: MCT2ES1(TA) supports collector-emitter voltage up to 80V, while MCT2ESM is rated to 30V. Applications requiring switching of voltages above 30V must use MCT2ES1(TA). Most standard logic-level switching applications operate well within 30V, making MCT2ESM suitable for these designs.

Q: Are both parts RoHS3 compliant?

A: MCT2ES1(TA) is explicitly RoHS3 compliant with MSL Level 1 rating. Compliance information for MCT2ESM is not provided in the available specifications. Verify RoHS3 compliance status with Fairchild Semiconductor for applications requiring regulatory certification.
