MCT2ESVM Equivalent & Substitute Parts

Part Overview

The MCT2ESVM is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 7500Vpk isolation rating. This component features a single-channel transistor output configuration in a 6-SMD surface mount package. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT2ESVM is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of Channels: 1 (single channel required)
• Voltage - Isolation: 7500Vpk (minimum isolation rating)
• Output Type: Transistor with Base (functional output configuration)
• Mounting Type: Surface Mount (assembly compatibility)
• Package / Case: 6-SMD, Gull Wing (physical and electrical footprint)

Secondary Compatibility Parameters:

• Current Transfer Ratio (Min): 20% @ 10mA or higher
• Voltage - Output (Max): 30V or higher
• Current - Output / Channel: 50mA or higher
• Operating Temperature Range: Must encompass -40°C ~ 100°C or broader

The MCT2ESVM has two identified substitute parts: MCT2ESM (parametric equivalent from Fairchild Semiconductor) and MCT2ESMT&R (similar part from Isocom Components 2004 LTD). Both maintain the core functional and physical specifications required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

MCT2ESM (Fairchild Semiconductor) is the primary parametric equivalent for MCT2ESVM replacement. This part maintains identical electrical specifications across all critical parameters including isolation voltage (7500Vpk), current transfer ratio (20% @ 10mA), switching times (2µs), and output characteristics. The MCT2ESM is currently in active production status, ensuring long-term availability and supply chain stability. Both parts share identical operating temperature range (-40°C ~ 100°C) and package configuration (6-SMD, Gull Wing).

MCT2ESMT&R (Isocom Components 2004 LTD) is classified as a similar part rather than a direct parametric equivalent due to a critical specification deviation: the isolation voltage is rated at 7.5Vpk rather than 7500Vpk. This represents a significant reduction in isolation capability and makes this part unsuitable for applications requiring the full 7500Vpk isolation rating of the original MCT2ESVM. The MCT2ESMT&R does offer advantages in current transfer ratio (50% @ 10mA versus 20%) and extended operating temperature range (-55°C ~ 100°C), but these benefits do not offset the isolation voltage limitation. This part is suitable only for applications where lower isolation voltage is acceptable.

For direct replacement of MCT2ESVM in existing designs, MCT2ESM is the recommended selection based on complete parametric equivalence and active product status.

Frequently Asked Questions (FAQ)

Q: Can MCT2ESM be used as a direct replacement for MCT2ESVM?

A: Yes. MCT2ESM is a parametric equivalent with identical specifications for isolation voltage (7500Vpk), current transfer ratio (20% @ 10mA), switching times, output voltage and current ratings, and operating temperature range. Both parts use the same 6-SMD, Gull Wing package configuration, enabling direct substitution without circuit modification.

Q: Why is MCT2ESMT&R not recommended as a primary substitute?

A: MCT2ESMT&R has an isolation voltage rating of 7.5Vpk, which is significantly lower than the 7500Vpk requirement of MCT2ESVM. This part is suitable only for applications with lower isolation voltage requirements. Use MCT2ESMT&R only if your application can operate with reduced isolation voltage.

Q: Are there packaging differences between MCT2ESM and MCT2ESVM?

A: No. Both parts use identical 6-SMD, Gull Wing surface mount packaging, ensuring compatibility with existing PCB layouts and assembly processes.

Q: What is the significance of MCT2ESVM being obsolete?

A: The obsolete status of MCT2ESVM indicates that onsemi has discontinued production. MCT2ESM from Fairchild Semiconductor is the recommended active alternative, providing equivalent functionality with assured ongoing availability.

Q: Do switching time differences affect substitution suitability?

A: MCT2ESM maintains identical turn-on and turn-off times (2µs, 2µs) as MCT2ESVM. MCT2ESMT&R has slightly longer switching times (3µs, 3µs), which may impact circuit performance in timing-critical applications. Verify switching time requirements before selecting MCT2ESMT&R.

Q: What compliance certifications apply to these parts?

A: MCT2ESVM and MCT2ESM share ECCN EAR99 and HTSUS 8541.49.8000 classifications. MCT2ESMT&R includes additional RoHS3 compliance certification. All three parts are REACH Unaffected.
