Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCT2ES1(TA)-V are identified based on the following critical parameters that define functional compatibility:

Primary Compatibility Criteria:

• Single channel optoisolator configuration
• Transistor output with base terminal access
• DC input type
• 6-SMD surface mount package with gull wing leads
• Isolation voltage rating (minimum 5000Vrms or equivalent peak voltage specification)
• Current transfer ratio minimum 20% @ 10mA
• Vce saturation maximum 400mV
• Operating temperature range overlap capability

Substitution Logic: The MCT2ESM qualifies as a substitute part because it maintains identical channel count, output type, input type, package configuration, and critical electrical parameters. While the MCT2ESM features higher isolation voltage (7500Vpk), lower maximum output voltage (30V vs 80V), and a narrower operating temperature range (-40°C to 100°C vs -55°C to 110°C), these differences represent enhanced or equivalent performance in isolation capability with trade-offs in output voltage headroom and temperature extremes. The matching current transfer ratio, Vce saturation specification, and identical package form factor establish direct substitution viability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

MCT2ES1(TA)-V Selection Criteria:

• Primary choice for applications requiring maximum output voltage capability (80V)
• Extended operating temperature range (-55°C to 110°C) for extreme environment applications
• Everlight Electronics sourcing preference or supply chain continuity
• RoHS3 compliance requirement with MSL Level 1 moisture sensitivity

MCT2ESM Selection Criteria:

• Applications where higher isolation voltage (7500Vpk) provides additional safety margin
• Faster switching performance required (2µs turn-on/off vs 3µs)
• Output voltage requirements within 30V maximum specification
• Operating temperature range -40°C to 100°C acceptable for application
• Fairchild Semiconductor sourcing preference or alternative supply chain
• Applications where 50mA output current specification is sufficient

Both parts maintain Active product status and identical package configuration, supporting direct PCB layout compatibility. Selection between these optoisolators should be based on specific application voltage, temperature, and switching speed requirements rather than general substitution preference.

Frequently Asked Questions (FAQ)

Q: Can MCT2ESM directly replace MCT2ES1(TA)-V on existing PCBs?

A: Yes, direct PCB replacement is supported. Both components use identical 6-SMD gull wing package configuration with matching pin assignments for single-channel optoisolator transistor output with base terminal. No layout modifications are required.

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

A: MCT2ES1(TA)-V provides 5000Vrms isolation, while MCT2ESM provides 7500Vpk isolation. These represent different measurement standards (RMS vs peak) but both exceed 5000V isolation capability. MCT2ESM offers higher isolation margin for safety-critical applications.

Q: Are there output voltage limitations when substituting MCT2ESM for MCT2ES1(TA)-V?

A: Yes. MCT2ESM maximum output voltage is 30V compared to MCT2ES1(TA)-V at 80V. Applications requiring output voltages above 30V must use MCT2ES1(TA)-V. Verify circuit design output voltage requirements before substitution.

Q: How do switching speeds compare between these optoisolators?

A: MCT2ESM provides faster switching performance with 2µs turn-on/off time and 2µs/1.5µs rise/fall times, compared to MCT2ES1(TA)-V at 3µs for all timing parameters. MCT2ESM is suitable for higher-frequency switching applications.

Q: What are the operating temperature range implications for substitution?

A: MCT2ES1(TA)-V operates from -55°C to 110°C, while MCT2ESM operates from -40°C to 100°C. For applications requiring operation below -40°C or above 100°C, MCT2ES1(TA)-V is required. Standard industrial temperature range applications (-40°C to 85°C) support either part.

Q: Do both parts meet the same compliance standards?

A: Both parts are Active status products with identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. MCT2ES1(TA)-V specifies RoHS3 compliance with MSL Level 1. Verify specific compliance documentation for MCT2ESM if regulatory requirements are critical to application.

Q: Is current transfer ratio performance identical between these parts?

A: Yes, both parts specify minimum 20% current transfer ratio @ 10mA. Vce saturation is also identical at 400mV maximum. These core transistor output characteristics are matched between MCT2ES1(TA)-V and MCT2ESM.
