MCT62H Equivalent & Substitute Parts

Part Overview

The MCT62H is a 2-channel optoisolator with transistor output manufactured by Vishay Semiconductor Opto Division. It provides 5300Vrms isolation voltage and is designed for applications requiring high-voltage signal isolation in Through Hole 8-DIP packaging. The product is currently in Last Time Buy status, making identification of equivalent alternatives necessary for long-term design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT62H is determined by the following critical parameters:

• Package Compatibility: 8-DIP (0.300", 7.62mm) Through Hole mounting
• Channel Configuration: 2-channel transistor output optoisolator
• Isolation Voltage: Minimum 5000Vrms (MCT62H specifies 5300Vrms)
• Output Characteristics: Transistor output with maximum output voltage and current ratings
• Operating Temperature Range: Must support the application's thermal requirements
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The LTV-829 qualifies as a substitute based on matching package type, channel count, output type, and regulatory status. However, differences in isolation voltage, output voltage rating, and operating temperature range must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The LTV-829 is electrically and mechanically compatible with the MCT62H for applications where the following conditions are met:

• Maximum output voltage requirement does not exceed 35V (LTV-829 limit vs. MCT62H 70V)
• Isolation voltage requirement is satisfied by 5000Vrms (LTV-829 vs. MCT62H 5300Vrms)
• Minimum operating temperature requirement is -25°C or higher (LTV-829 lower limit vs. MCT62H -55°C)
• Current transfer ratio of 50% minimum is acceptable for the application (LTV-829 vs. MCT62H 100% minimum)

Both parts maintain ROHS3 compliance, MSL Level 1 rating, and identical Through Hole 8-DIP packaging, supporting direct PCB layout compatibility. The LTV-829 is currently in Active product status, providing long-term availability compared to the MCT62H Last Time Buy designation.

Frequently Asked Questions (FAQ)

Q: Can the LTV-829 directly replace the MCT62H on existing PCBs?

A: Yes, the LTV-829 is pin-compatible and uses identical 8-DIP (0.300", 7.62mm) Through Hole packaging. No PCB layout modifications are required.

Q: What is the primary difference in isolation voltage between these parts?

A: The MCT62H provides 5300Vrms isolation, while the LTV-829 provides 5000Vrms. Applications requiring isolation voltage above 5000Vrms must use the MCT62H or identify alternative parts with higher ratings.

Q: How do the current transfer ratios compare?

A: The MCT62H guarantees a minimum of 100% current transfer ratio at 5mA input current. The LTV-829 guarantees a minimum of 50% at the same input current. Applications with tight CTR requirements should account for this difference in circuit design.

Q: Are there temperature range limitations with the LTV-829?

A: The LTV-829 operates from -25°C to 100°C, while the MCT62H operates from -55°C to 100°C. Applications requiring operation below -25°C must use the MCT62H or select an alternative part with extended low-temperature range.

Q: What is the maximum output voltage difference?

A: The MCT62H supports maximum output voltage of 70V, while the LTV-829 supports 35V. Applications requiring output voltage above 35V must use the MCT62H or identify alternative parts with higher voltage ratings.

Q: Do both parts meet the same regulatory requirements?

A: Yes, both the MCT62H and LTV-829 are ROHS3 compliant, carry EAR99 ECCN classification, and have MSL Level 1 (Unlimited) moisture sensitivity rating.
