MCT2ES(TB)-V Equivalent & Substitute Parts

Part Overview

The MCT2ES(TB)-V 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 transistor output configuration in a 6-SMD surface mount package. The device is actively produced and RoHS3 compliant, making it suitable for industrial isolation applications requiring DC input control.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for optoisolator transistor devices. Substitution becomes necessary due to inventory availability, supply chain optimization, or design flexibility requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MCT2ES(TB)-V is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Single-channel optoisolator configuration
• Transistor output with base connection
• DC input type
• 6-SMD surface mount package with gull wing leads
• Minimum current transfer ratio of 20% @ 10mA
• Vce saturation maximum of 400mV
• Active product status with current manufacturing

Secondary Compatibility Parameters:

• Isolation voltage rating (minimum 5000Vrms required)
• Maximum output voltage rating (minimum 80V required)
• Operating temperature range overlap
• RoHS compliance status

The MCT2ESM from Fairchild Semiconductor qualifies as a substitute based on matching the primary criteria while exceeding isolation voltage specifications and maintaining compatible electrical characteristics.

Engineering Selection Recommendations

MCT2ES(TB)-V (Primary Selection):

• Everlight Electronics manufacture with active product status
• RoHS3 compliant
• Extended operating temperature range (-55°C ~ 110°C) suitable for industrial environments
• Maximum output voltage rating of 80V accommodates higher voltage switching applications
• 706 units in stock

MCT2ESM (Substitute Selection):

• Fairchild Semiconductor manufacture with active product status
• Higher isolation voltage rating (7500Vpk) provides additional safety margin
• Faster switching characteristics (2µs turn-on/off, 2µs/1.5µs rise/fall times)
• Lower maximum output voltage rating (30V) limits application scope to lower voltage circuits
• Reduced operating temperature range (-40°C ~ 100°C) excludes extreme cold environments
• 5300 units in stock

Selection Basis: Use MCT2ES(TB)-V for applications requiring output voltages above 30V or operating temperatures below -40°C or above 100°C. Use MCT2ESM when faster switching response is prioritized and output voltage requirements do not exceed 30V within the -40°C ~ 100°C operating window.

Frequently Asked Questions (FAQ)

Q: Can MCT2ESM replace MCT2ES(TB)-V in all applications?

A: No. The MCT2ESM has a maximum output voltage rating of 30V compared to 80V for the MCT2ES(TB)-V. Applications requiring output voltages above 30V must use the MCT2ES(TB)-V. Additionally, the MCT2ESM operating temperature range (-40°C ~ 100°C) is narrower than the MCT2ES(TB)-V range (-55°C ~ 110°C).

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are: single-channel configuration, transistor output with base, 20% minimum current transfer ratio at 10mA, 400mV maximum Vce saturation, DC input type, and 6-SMD gull wing package. Both parts match these specifications.

Q: Does the MCT2ESM provide better isolation performance?

A: The MCT2ESM isolation rating is 7500Vpk compared to 5000Vrms for the MCT2ES(TB)-V. The MCT2ESM exceeds the isolation requirement, providing additional safety margin in high-voltage isolation applications.

Q: Are there temperature-related substitution restrictions?

A: Yes. The MCT2ESM operating range is -40°C ~ 100°C, which excludes the lower temperature extreme of -55°C specified for the MCT2ES(TB)-V. Applications requiring operation below -40°C must use the MCT2ES(TB)-V.

Q: How do switching speeds compare between these parts?

A: The MCT2ESM has faster switching characteristics with 2µs turn-on/off times and 2µs/1.5µs rise/fall times, compared to 3µs for all timing parameters on the MCT2ES(TB)-V. This makes MCT2ESM suitable for higher-frequency switching applications within its voltage and temperature constraints.

Q: Are both parts RoHS compliant?

A: The MCT2ES(TB)-V is explicitly RoHS3 compliant. RoHS compliance status for the MCT2ESM is not provided in the available specifications.

Q: What is the package compatibility between these parts?

A: Both parts use identical 6-SMD surface mount packages with gull wing leads, ensuring PCB layout and footprint compatibility.
