Substitute Part Grouping Explanation

Substitute parts for the MCT61G are identified based on strict equivalence across the following critical parameters:

• Number of Channels: 2
• Voltage - Isolation: 5300Vrms
• Current Transfer Ratio (Min): 50% @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 30V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 400mV
• Operating Temperature: -25°C ~ 100°C
• Package / Case: 8-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole

The MCT61XG maintains identical electrical and mechanical specifications across all critical parameters, confirming full parametric equivalence within the MCT61 series.

Parameter Comparison

Engineering Selection Recommendations

Both MCT61G and MCT61XG are active products manufactured by Isocom Components 2004 LTD with identical compliance certifications. Both parts are ROHS3 compliant and carry REACH Unaffected status. Selection between these parts is based on inventory availability and supply chain requirements, as electrical and mechanical specifications are equivalent. The MCT61XG currently maintains higher inventory levels (1109 Pcs vs 792 Pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can MCT61XG be used as a direct replacement for MCT61G?

A: Yes. The MCT61XG is a parametric equivalent with identical electrical characteristics across all critical parameters including isolation voltage, current transfer ratio, output voltage, output current, and saturation voltage. Both parts use the same 8-DIP through-hole package.

Q: Are there any differences in compliance or certifications between MCT61G and MCT61XG?

A: No. Both parts carry identical RoHS3 compliance and REACH Unaffected status. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What determines substitutability for MCT61 series optoisolators?

A: Substitutability is determined by equivalence in isolation voltage (5300Vrms), number of channels (2), current transfer ratio (50% @ 5mA minimum), output type (transistor), maximum output voltage (30V), maximum output current per channel (50mA), maximum Vce saturation (400mV), operating temperature range (-25°C ~ 100°C), and package configuration (8-DIP through-hole).

Q: Can these parts be used in applications requiring different isolation voltages?

A: No. Both MCT61G and MCT61XG are rated for 5300Vrms isolation. Applications requiring different isolation specifications require alternative part numbers outside this equivalence group.

Q: Are there package or pinout differences between MCT61G and MCT61XG?

A: No. Both parts use identical 8-DIP (0.400", 10.16mm) through-hole packaging with the same pinout configuration.
