MCT623SD Equivalent & Substitute Parts

Part Overview

The MCT623SD 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 unlimited moisture sensitivity rating. Alternative part numbers become necessary when specific packaging formats are required, inventory constraints exist, or supply chain optimization is needed while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The MCT62SD qualifies as a parametric equivalent to the MCT623SD based on strict electrical and mechanical compatibility. Substitution is valid when the following criteria are met:

Critical Matching Parameters:

• Isolation voltage: 5000Vrms (identical)
• Number of channels: 2 (identical)
• Current transfer ratio: 100% @ 5mA (identical)
• Output type: Transistor (identical)
• Maximum output voltage: 30V (identical)
• Maximum output current per channel: 30mA (identical)
• Switching times: 2.4µs turn-on and turn-off (identical)
• Vce saturation: 400mV maximum (identical)
• Operating temperature range: -55°C ~ 100°C (identical)
• Package type: 8-SMD, Gull Wing (identical)
• Compliance: ROHS3 Compliant, MSL 1 (identical)

The only difference between these parts is the packaging format: MCT623SD is supplied in Tape & Reel (TR) format, while MCT62SD is supplied in Cut Tape (CT) & Digi-Reel® format. This distinction affects procurement and handling but does not alter electrical performance or functional capability.

Parameter Comparison

Engineering Selection Recommendations

Both MCT623SD and MCT62SD are active products from onsemi with identical electrical specifications and compliance certifications. Selection between these parts should be based on packaging requirements and supply chain logistics:

MCT623SD (Tape & Reel): Suitable for high-volume automated assembly operations where continuous reel feeding is preferred.

MCT62SD (Cut Tape & Digi-Reel®): Suitable for lower-volume applications, mixed-component assembly, or when individual component handling is required.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing processes and storage conditions. No functional or performance trade-offs exist between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can MCT62SD replace MCT623SD in my circuit design? A: Yes. Both parts are electrically and mechanically identical. The MCT62SD operates with the same isolation voltage (5000Vrms), channel count (2), output characteristics (30V, 30mA), and switching performance (2.4µs). Substitution is valid for all functional requirements.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) supplies components on continuous reels for automated pick-and-place equipment. Cut Tape (CT) & Digi-Reel® provides components in shorter tape segments or alternative reel formats, typically for lower-volume or mixed-assembly applications. The components themselves are identical.

Q: Are there any compliance differences between MCT623SD and MCT62SD? A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. They meet the same regulatory and environmental standards.

Q: Can I use MCT62SD in a design originally specified for MCT623SD? A: Yes, provided your assembly process can accommodate Cut Tape & Digi-Reel® packaging. All electrical and thermal characteristics are identical, and both parts are active products with full manufacturer support.

Q: What parameters must match for these parts to be considered equivalent? A: Critical parameters include isolation voltage (5000Vrms), channel count (2), output type (transistor), maximum output voltage (30V), maximum output current (30mA), switching times (2.4µs), saturation voltage (400mV), operating temperature range (-55°C to 100°C), and package type (8-SMD, Gull Wing). All these parameters are identical between MCT623SD and MCT62SD.
