MCT6G Optoisolator - Equivalent & Substitute Parts

Part Overview

The MCT6G is a dual-channel optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 5300Vrms and is designed for applications requiring electrical isolation between input and output circuits. The part is currently in active production status with 768 units available in stock. Alternative part numbers within the same series may be required due to inventory constraints, design revisions, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT6G is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5300Vrms
• Number of Channels: 2
• Output Type: Transistor
• Current Transfer Ratio (Min): 20% @ 10mA
• Maximum Output Voltage: 30V
• Maximum Output Current per Channel: 50mA
• Vce Saturation (Max): 400mV
• Package Type: 8-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole
• Operating Temperature Range: -25°C ~ 100°C

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The MCT6XG meets all specified criteria and is therefore a valid substitute for the MCT6G.

Parameter Comparison

Engineering Selection Recommendations

The MCT6XG is a direct parametric equivalent to the MCT6G. Both parts are manufactured by Isocom Components 2004 LTD within the MCT6 series and share identical electrical and mechanical specifications. Both parts maintain active product status and comply with ROHS3 and REACH requirements. Selection between MCT6G and MCT6XG may be based on inventory availability, with MCT6XG currently showing higher stock levels (856 units versus 768 units). No functional or performance differences exist between these parts for applications requiring dual-channel optoisolation at 5300Vrms with transistor output in 8-DIP through-hole packaging.

Frequently Asked Questions (FAQ)

Q: Can MCT6XG be used as a direct replacement for MCT6G in existing designs?

A: Yes. The MCT6XG meets all electrical and mechanical parameters of the MCT6G, including isolation voltage, channel count, output type, current ratings, and package specifications. No circuit modifications are required.

Q: Are there any differences in compliance or certifications between MCT6G and MCT6XG?

A: No. Both parts carry identical ROHS3 compliance status and REACH unaffected designation. Both are classified under the same ECCN and HTSUS codes.

Q: What determines whether a part can substitute for the MCT6G?

A: Substitution eligibility requires matching all critical parameters: 5300Vrms isolation voltage, 2-channel configuration, transistor output type, 20% minimum current transfer ratio, 30V maximum output voltage, 50mA per-channel output current, 400mV maximum Vce saturation, 8-DIP through-hole package, and -25°C to 100°C operating temperature range.

Q: Is the 8-DIP package compatible with existing PCB layouts designed for MCT6G?

A: Yes. Both MCT6G and MCT6XG use identical 8-DIP (0.400", 10.16mm) through-hole packaging and are mechanically interchangeable on PCBs designed for this package type.

Q: What is the difference between MCT6G and MCT6XG part numbers?

A: The part numbers differ only in the suffix designation (G versus XG). All electrical specifications, performance characteristics, and compliance certifications are identical between these variants within the MCT6 series.
