MCT2ETVM Equivalent & Substitute Parts

Part Overview

The MCT2ETVM is an optoisolator transistor with base output manufactured by onsemi, rated for 7500Vpk isolation voltage in a 6-DIP through-hole package. This component provides galvanic isolation for single-channel signal transmission with integrated base output control. The part is currently obsolete, making equivalent substitutes necessary for new designs or component replenishment in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT2ETVM is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Package / Case: 6-DIP (0.400", 10.16mm) — ensures mechanical and electrical pin compatibility
• Number of Channels: 1 — single-channel isolation requirement
• Output Type: Transistor with Base — functional output configuration
• Mounting Type: Through Hole — PCB assembly method compatibility
• Input Type: DC — signal input specification

Performance Tolerance Parameters:

• Voltage - Isolation: Minimum 7500Vpk (MCT2ETVM specification) — substitutes with lower isolation ratings (5000Vrms) represent reduced isolation capability
• Current Transfer Ratio (Min): 20% @ 10mA or higher — ensures adequate signal transmission efficiency
• Voltage - Output (Max): 30V or higher — output voltage handling capability
• Current - Output / Channel: 50mA or higher — output current capacity
• Vce Saturation (Max): 400mV — transistor saturation performance
• Operating Temperature: Must encompass or exceed -40°C ~ 100°C range

Substitute parts are grouped by isolation voltage rating. Parts meeting all mandatory criteria with isolation ratings below 7500Vpk are classified as functional equivalents with reduced isolation margin.

Engineering Selection Recommendations

Primary Substitute: MCT2EG

MCT2EG is the direct equivalent listed in the MCT2ETVM substitutes field. Manufactured by Isocom Components, this part maintains the same base product number (MCT2) and shares identical package, output type, and saturation characteristics. MCT2EG is currently active and ROHS3 compliant, providing long-term availability and regulatory compliance for new designs.

Secondary Substitutes: Everlight H11A Series (H11A2M-V, H11A3M-V, H11A5M-V)

The Everlight H11A2M-V, H11A3M-V, and H11A5M-V are functionally compatible alternatives with 5000Vrms isolation rating. These parts are active products with ROHS3 compliance and extended operating temperature ranges (-55°C ~ 110°C). H11A5M-V offers the highest current transfer ratio (30% @ 10mA) among this group, matching the MCT2ETVM minimum specification. H11A2M-V and H11A3M-V provide 20% current transfer ratio, equivalent to MCT2ETVM. H11A4M-V is not recommended due to reduced current transfer ratio (10% @ 10mA).

Alternative Substitute: LTV-702VM

LTV-702VM from Lite-On Inc. provides 5000Vrms isolation with the highest current transfer ratio range (40% ~ 320% @ 10mA) and matching output current capacity (50mA). This part is active and ROHS3 compliant. Operating temperature range (-55°C ~ 100°C) encompasses the MCT2ETVM specification.

Isolation Voltage Consideration:

All substitute parts operate at 5000Vrms isolation, which is lower than the MCT2ETVM 7500Vpk rating. Applications requiring the full 7500Vpk isolation margin must evaluate whether 5000Vrms isolation is sufficient for the intended circuit design.

Frequently Asked Questions (FAQ)

Q: Can MCT2EG directly replace MCT2ETVM without circuit modification?

A: MCT2EG shares the same base product number, package, output configuration, and key electrical parameters (30V max output, 50mA output current, 400mV saturation). Pin-for-pin compatibility is maintained. No circuit modification is required for mechanical and functional substitution.

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

A: These are different measurement standards for isolation voltage. 7500Vpk (peak voltage) and 5000Vrms (root mean square voltage) represent different isolation specifications. Applications designed for 7500Vpk isolation should evaluate whether 5000Vrms meets the required safety or performance margin for the specific circuit.

Q: Why is H11A4M-V not recommended as a substitute?

A: H11A4M-V has a minimum current transfer ratio of 10% @ 10mA, which is below the MCT2ETVM specification of 20% @ 10mA. This reduced transfer ratio may result in insufficient signal transmission efficiency in circuits designed for the higher 20% minimum specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MCT2EG, all Everlight H11A variants (H11A2M-V, H11A3M-V, H11A4M-V, H11A5M-V), and LTV-702VM are ROHS3 compliant. The original MCT2ETVM compliance status is not specified in the provided data.

Q: Do substitute parts support the same operating temperature range?

A: Substitute parts support extended temperature ranges. MCT2EG, LTV-702VM, and all Everlight H11A variants operate from -55°C to 100°C or -55°C to 110°C, which encompasses or exceeds the MCT2ETVM range of -40°C to 100°C.

Q: Which substitute offers the best current transfer ratio performance?

A: LTV-702VM provides the highest current transfer ratio (40% minimum @ 10mA) and maximum range (320% @ 10mA). H11A5M-V offers 30% minimum @ 10mA. Both exceed the MCT2ETVM 20% minimum specification, providing improved signal transmission efficiency.

Q: Are all substitutes available in the same 6-DIP package?

A: Yes. All substitute parts are packaged in 6-DIP (0.400", 10.16mm) through-hole configuration, ensuring mechanical compatibility with existing PCB layouts designed for MCT2ETVM.
