MCT2ES1(TB) Equivalent & Substitute Parts

Part Overview

The MCT2ES1(TB) 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 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, current transfer ratio, switching characteristics, output voltage ratings, and thermal operating ranges while preserving the 6-SMD gull wing package format.

Key Parameters

Substitute Part Grouping Explanation

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

Isolation Voltage: The MCT2ES1(TB) specifies 5000Vrms isolation. Substitute parts must maintain isolation voltage at or above this threshold to preserve circuit safety margins.

Current Transfer Ratio: Minimum CTR of 20% @ 10mA is the baseline performance criterion. Substitute parts must meet or exceed this specification to ensure reliable signal transfer across the isolation barrier.

Switching Speed: Turn-on and turn-off times of 3µs establish the maximum acceptable propagation delay. Substitute parts with equal or faster switching characteristics are acceptable.

Output Configuration: The transistor with base output topology is mandatory. Only parts with identical output stage architecture qualify as substitutes.

Output Voltage Rating: Maximum output voltage of 80V defines the maximum collector-emitter voltage capability. Substitute parts must support this voltage level or higher.

Package Format: The 6-SMD gull wing surface mount package is required for mechanical and thermal compatibility in existing PCB layouts.

Thermal Range: Operating temperature range of -55°C to 110°C establishes the environmental operating envelope. Substitute parts must cover this full range or a superset thereof.

Compliance: RoHS3 compliance and MSL Level 1 rating are mandatory for supply chain and manufacturing process compatibility.

Parameter Comparison

Engineering Selection Recommendations

MCT2ES1(TB) Primary Selection: Use the MCT2ES1(TB) when the application requires the full 80V maximum output voltage rating and extended operating temperature range from -55°C to 110°C. This part is Active status with confirmed RoHS3 compliance and MSL Level 1 rating. Current inventory of 800 pcs supports immediate availability.

MCT2ESM Substitute Consideration: The MCT2ESM qualifies as a substitute when output voltage requirements do not exceed 30V and operating temperature range can be constrained to -40°C to 100°C. The MCT2ESM provides superior isolation voltage (7500Vpk versus 5000Vrms) and faster switching characteristics (2µs versus 3µs). This part is Active status with 5300 pcs in inventory. Both parts share identical current transfer ratio, forward current rating, saturation voltage, and 6-SMD gull wing package format.

Compliance Verification: Both parts carry EAR99 ECCN classification and 8541.49.8000 HTSUS code. RoHS3 compliance is confirmed for MCT2ES1(TB). Fairchild Semiconductor MCT2ESM compliance status should be verified against current component documentation.

Frequently Asked Questions (FAQ)

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

A: No. The MCT2ESM has a maximum output voltage of 30V compared to 80V for the MCT2ES1(TB). Applications requiring output voltages above 30V must use the MCT2ES1(TB). Additionally, the MCT2ESM operating temperature range (-40°C to 100°C) is narrower than the MCT2ES1(TB) range (-55°C to 110°C).

Q: What are the key electrical parameters that determine substitutability?

A: The critical parameters are: isolation voltage (minimum 5000Vrms), current transfer ratio (minimum 20% @ 10mA), output voltage rating (minimum 80V), maximum output current capability, switching speed (turn-on/turn-off times), and saturation voltage. All must meet or exceed the MCT2ES1(TB) specifications.

Q: Are the packages physically identical?

A: Yes. Both MCT2ES1(TB) and MCT2ESM use 6-SMD gull wing surface mount packages. PCB footprints and reflow soldering profiles are compatible.

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

A: 5000Vrms is the RMS (root mean square) voltage rating, while 7500Vpk is the peak voltage rating. These represent different measurement standards for isolation voltage. The MCT2ESM specification of 7500Vpk exceeds the MCT2ES1(TB) requirement of 5000Vrms, providing additional isolation margin.

Q: Can I use MCT2ES1(TB) in place of MCT2ESM?

A: Yes, provided the application does not require the faster switching speed of the MCT2ESM (2µs versus 3µs). The MCT2ES1(TB) has superior output voltage rating (80V versus 30V) and wider operating temperature range, making it suitable for more demanding applications.

Q: What inventory status should I verify before ordering?

A: Confirm current stock levels with your supplier. MCT2ES1(TB) has 800 pcs listed as new original in stock. MCT2ESM has 5300 pcs available. Verify these quantities match your procurement timeline and volume requirements.
