MCT5200W Equivalent & Substitute Parts

Part Overview

The MCT5200W is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 5300Vrms isolation rating. This component features a single-channel configuration in a 6-DIP package with transistor output and integrated base connection. The MCT5200W is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT5200W is determined by the following critical parameters:

• Isolation Voltage Rating: Minimum 5300Vrms required for equivalent isolation performance
• Output Configuration: Transistor with base output mandatory for circuit compatibility
• Number of Channels: Single-channel configuration required
• Maximum Output Voltage: 30V maximum rating
• Maximum Output Current: 150mA per channel minimum
• Package Type: 6-DIP through-hole mounting
• Vce Saturation: 400mV maximum for switching performance equivalence

The MCT5210M is identified as a substitute part. However, the MCT5210M operates at 4170Vrms isolation voltage, which is lower than the MCT5200W specification of 5300Vrms. This represents a functional downgrade in isolation capability and is suitable only for applications where the lower isolation rating is acceptable.

Engineering Selection Recommendations

The MCT5200W is obsolete and no longer in active production. The MCT5210M is the identified substitute from onsemi's current product line and maintains active manufacturing status.

Critical Considerations for Substitution:

• Isolation Voltage Downgrade: The MCT5210M operates at 4170Vrms compared to the MCT5200W's 5300Vrms. Applications requiring the full 5300Vrms isolation specification cannot use this substitute without circuit redesign or additional isolation measures.

• Package Dimension Variance: The MCT5210M uses a 6-DIP package with 0.300" (7.62mm) body width versus the MCT5200W's 0.400" (10.16mm) width. PCB footprint compatibility must be confirmed before implementation.

• Operating Temperature Range: The MCT5210M supports -40°C to 100°C versus the MCT5200W's -55°C to 100°C. Applications requiring operation below -40°C cannot use the MCT5210M.

• Compliance Status: The MCT5210M carries RoHS3 compliance certification, whereas the MCT5200W status is not specified. The MCT5210M is REACH Unaffected, matching the MCT5200W classification.

Frequently Asked Questions (FAQ)

Q: Can the MCT5210M directly replace the MCT5200W in existing designs?

A: Direct replacement is not recommended without design review. The MCT5210M has a lower isolation voltage rating (4170Vrms vs. 5300Vrms) and different package body dimensions (0.300" vs. 0.400" width). PCB layout compatibility and isolation voltage requirements must be evaluated.

Q: What is the primary difference between these two parts?

A: The MCT5200W provides higher isolation voltage (5300Vrms) and operates across a wider temperature range (-55°C to 100°C). The MCT5210M is the active production alternative with lower isolation voltage (4170Vrms) and narrower temperature range (-40°C to 100°C).

Q: Are there package compatibility issues?

A: Yes. The MCT5200W uses a 6-DIP package with 0.400" body width, while the MCT5210M uses 0.300" body width. Existing PCB designs may require footprint modification or adapter solutions.

Q: Which part should be selected for new designs?

A: For new designs, the MCT5210M is the recommended choice as it is actively manufactured by onsemi. However, isolation voltage and operating temperature requirements must align with application specifications.

Q: What compliance certifications apply to the MCT5210M?

A: The MCT5210M is RoHS3 compliant and REACH Unaffected. These certifications support use in regulated markets and applications with environmental compliance requirements.
