MCT2201300 Equivalent & Substitute Parts

Part Overview

The MCT2201300 is an optoisolator transistor with base output manufactured by onsemi, featuring 5300Vrms isolation voltage in a 6-DIP package. This component provides galvanic isolation for low-speed switching applications with a single transistor output channel. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new designs requiring similar isolation performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCT2201300 is determined by the following critical parameters:

• Isolation Voltage: Minimum 5300Vrms required for equivalent performance
• Output Configuration: Transistor with base output mandatory for circuit compatibility
• Package Type: 6-DIP form factor for mechanical fit
• Current Transfer Ratio: Minimum 100% @ 10mA for functional equivalence
• Output Voltage Rating: Minimum 30V to support existing circuit designs
• Output Current Capability: Minimum 50mA per channel
• Vce Saturation: Maximum 400mV for switching performance

Based on these criteria, the MCT2201 from onsemi qualifies as a direct substitute. The H11AV1VM from Fairchild Semiconductor provides functional substitution with trade-offs in isolation voltage (4170Vrms) and output voltage rating (70V), suitable only for applications where lower isolation voltage is acceptable.

Parameter Comparison

Engineering Selection Recommendations

MCT2201: This onsemi part provides identical electrical specifications to the MCT2201300 and maintains the same product family lineage. Both parts are obsolete, but MCT2201 offers higher inventory availability (2130 pcs vs 845 pcs). Selection is appropriate for designs requiring exact parameter matching and where onsemi component qualification is specified.

H11AV1VM: This Fairchild Semiconductor optoisolator is active in production, ensuring long-term availability. It meets the core isolation and output configuration requirements but operates at reduced isolation voltage (4170Vrms vs 5300Vrms) and provides higher maximum output voltage (70V vs 30V). This substitute is suitable for applications where the lower isolation voltage specification is acceptable and where active product status is required for supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can H11AV1VM replace MCT2201300 in all applications?

A: H11AV1VM is functionally compatible for transistor output isolation applications using the 6-DIP package. However, the reduced isolation voltage (4170Vrms vs 5300Vrms) means it is not suitable for high-voltage isolation circuits designed for the full 5300Vrms rating. Verify your circuit's isolation voltage requirement before substitution.

Q: What is the primary advantage of MCT2201 over MCT2201300?

A: MCT2201 provides identical electrical performance with higher inventory availability. Both are obsolete onsemi products within the same MCT2 base family, making MCT2201 the preferred substitute when exact parameter matching is required.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts use the 6-DIP (0.300", 7.62mm) package and are through-hole mounted, ensuring direct mechanical compatibility on PCBs designed for this form factor.

Q: What is the significance of the 400mV Vce Saturation specification?

A: Vce Saturation determines the voltage drop across the transistor output in saturation state. All three parts specify 400mV maximum, ensuring equivalent switching performance and power dissipation characteristics in the output stage.

Q: Why does H11AV1VM show higher maximum output voltage?

A: The H11AV1VM is rated for 70V maximum output voltage compared to 30V for the onsemi parts. This reflects different design specifications but does not affect substitution for circuits operating within the 30V range.
