MCT5210W Equivalent & Substitute Parts

Part Overview

The MCT5210W 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 and is rated for 150mA output current with transistor-based output architecture including base connection.

The MCT5210W is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT5210W is determined by the following critical parameters:

• Isolation Voltage Rating: The substitute must meet or exceed the 5300Vrms isolation requirement
• Output Configuration: Must be transistor with base output to maintain circuit compatibility
• Number of Channels: Single-channel configuration required
• Output Current Capability: Minimum 150mA per channel
• Maximum Output Voltage: 30V rating
• Package Type: 6-DIP through-hole mounting
• Vce Saturation: Maximum 400mV specification

The MCT5210M is identified as a substitute part. However, the MCT5210M features a lower isolation voltage rating of 4170Vrms, which does not meet the minimum 5300Vrms requirement of the MCT5210W. This represents a downgrade in isolation performance and does not qualify as a direct substitute for applications requiring the full 5300Vrms isolation specification.

Engineering Selection Recommendations

The MCT5210W is obsolete and no longer in production. The MCT5210M is the identified substitute part and is currently in active production status with ROHS3 compliance certification.

Selection of MCT5210M as a replacement requires engineering evaluation of the following factors:

• Isolation Voltage Downgrade: The MCT5210M provides 4170Vrms isolation versus the 5300Vrms of the MCT5210W. Applications requiring the full 5300Vrms isolation rating cannot use MCT5210M without circuit redesign or additional isolation measures.
• Operating Temperature Range: The MCT5210M operates from -40°C to 100°C, compared to -55°C to 100°C for MCT5210W. Applications requiring operation below -40°C are not compatible with MCT5210M.
• Package Dimensions: The MCT5210M uses a 6-DIP (0.300", 7.62mm) body versus 6-DIP (0.400", 10.16mm) for MCT5210W. PCB layout and socket compatibility must be verified.
• Compliance Status: MCT5210M holds ROHS3 compliance and REACH Unaffected status, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can MCT5210M directly replace MCT5210W in all applications?

A: No. The MCT5210M has a lower isolation voltage rating (4170Vrms versus 5300Vrms). Direct substitution is only possible in applications where the lower isolation voltage is acceptable. Applications requiring 5300Vrms isolation cannot use MCT5210M without circuit modification.

Q: What is the difference in package dimensions between these parts?

A: MCT5210W uses a 6-DIP package with 0.400" (10.16mm) body width, while MCT5210M uses a 6-DIP package with 0.300" (7.62mm) body width. PCB footprints and through-hole socket specifications must be verified for compatibility.

Q: Are there compliance differences between MCT5210W and MCT5210M?

A: MCT5210M is ROHS3 compliant, while MCT5210W status is not specified in the provided data. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: What is the operating temperature range difference?

A: MCT5210W operates from -55°C to 100°C, while MCT5210M operates from -40°C to 100°C. Applications requiring operation below -40°C require MCT5210W or alternative components rated for lower temperatures.

Q: How do the current transfer ratios compare?

A: MCT5210W specifies 60% minimum CTR at 3mA, while MCT5210M specifies 70% minimum CTR at 3mA. MCT5210M provides superior current transfer efficiency.
