MCT623S Equivalent & Substitute Parts

Part Overview

The MCT623S is an optoisolator with transistor output manufactured by onsemi, designed for applications requiring galvanic isolation up to 5000Vrms across 2 channels. This component is classified as an active product with full RoHS3 compliance and REACH unaffected status. Alternative part numbers may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The MCT62S qualifies as a parametric equivalent to the MCT623S based on strict alignment of all critical electrical and mechanical parameters. Substitution is valid when the following parameters match identically:

• Number of Channels: 2
• Voltage - Isolation: 5000Vrms
• Current Transfer Ratio (Min): 100% @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 30V
• Current - Output / Channel: 30mA
• Vce Saturation (Max): 400mV
• Operating Temperature: -55°C ~ 100°C
• Mounting Type: Surface Mount
• Package / Case: 8-SMD, Gull Wing
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The primary distinction between MCT623S and MCT62S is packaging format: MCT623S is supplied in Bulk packaging, while MCT62S is supplied in Tube packaging. This difference does not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both MCT623S and MCT62S are active products with identical RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and procurement logistics. MCT623S in Bulk packaging is suitable for high-volume manufacturing environments with integrated component handling systems. MCT62S in Tube packaging is appropriate for standard pick-and-place assembly operations and lower-volume production runs. Both parts meet all regulatory and environmental compliance requirements for equivalent circuit performance.

Frequently Asked Questions (FAQ)

Q: Can MCT62S replace MCT623S in existing designs? A: Yes. MCT62S is a parametric equivalent with identical electrical specifications and mechanical compatibility. The only difference is packaging format (Tube vs. Bulk).

Q: Are there any performance differences between MCT623S and MCT62S? A: No. Both parts have identical isolation voltage (5000Vrms), channel count (2), output current (30mA per channel), and operating temperature range (-55°C ~ 100°C).

Q: What is the significance of the packaging difference? A: Packaging format affects component handling and assembly logistics but does not impact electrical performance or PCB footprint. Bulk packaging is optimized for automated high-volume lines, while Tube packaging is standard for conventional assembly processes.

Q: Are both parts RoHS3 compliant? A: Yes. Both MCT623S and MCT62S are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity).

Q: Can these parts be used interchangeably on the same PCB? A: Yes. Both parts use identical 8-SMD Gull Wing package geometry and have matching pinouts, allowing direct substitution without PCB redesign.
