IL252-X016 Equivalent & Substitute Parts

Part Overview

The IL252-X016 is an optoisolator transistor with base output manufactured by Vishay Semiconductor Opto Division. This component provides 5300Vrms isolation in a 6-DIP through-hole package and is designed for AC/DC input applications with transistor output capability. The IL252-X016 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL252-X016 is determined by the following critical parameters:

• Isolation Voltage: The substitute must maintain isolation capability at or above the application requirement. The IL252-X016 provides 5300Vrms isolation.
• Output Configuration: The substitute must feature transistor output with base connection to maintain circuit compatibility.
• Number of Channels: Single-channel configuration is required.
• Input Type Compatibility: AC/DC input capability must be preserved.
• Maximum Output Voltage: 30V maximum output voltage specification must be met or exceeded.
• Package Type: Through-hole 6-DIP mounting is the mechanical requirement.
• Current Transfer Ratio: Minimum 100% @ 10mA ensures consistent signal transfer characteristics.
• Compliance Standards: RoHS3 compliance is mandatory for modern supply chain requirements.

The H11AA4TVM from onsemi is identified as a manufacturer-recommended substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The H11AA4TVM is an active product from onsemi and serves as the manufacturer-recommended substitute for the obsolete IL252-X016. Both components are ROHS3 compliant and share identical electrical characteristics for current transfer ratio, output voltage, saturation voltage, and forward current specifications.

The primary design consideration is isolation voltage: the H11AA4TVM provides 4170Vrms isolation compared to the IL252-X016's 5300Vrms. Selection of the H11AA4TVM is appropriate for applications where the required isolation voltage does not exceed 4170Vrms. For applications requiring isolation above 4170Vrms, alternative components with higher isolation ratings must be evaluated.

The operating temperature range of the H11AA4TVM (-40°C ~ 100°C) is narrower than the IL252-X016 (-55°C ~ 100°C). Applications requiring operation below -40°C must account for this specification difference.

Package dimensions differ slightly: the H11AA4TVM uses a 0.400" (10.16mm) DIP spacing compared to the IL252-X016's 0.300" (7.62mm) spacing. PCB layout verification is required to confirm mechanical compatibility with existing footprints.

Frequently Asked Questions (FAQ)

Q: Can the H11AA4TVM directly replace the IL252-X016 in all applications?

A: Direct replacement is possible only when the application isolation voltage requirement does not exceed 4170Vrms. The H11AA4TVM provides lower isolation voltage than the IL252-X016. Verify your circuit's isolation voltage specification before substitution.

Q: What is the significance of the different DIP package dimensions?

A: The IL252-X016 uses 0.300" (7.62mm) DIP spacing while the H11AA4TVM uses 0.400" (10.16mm) spacing. These are standard DIP variants. PCB footprints must be verified for mechanical compatibility. Standard 6-DIP sockets may accommodate both variants, but board-level routing and component placement must be confirmed.

Q: Are both components RoHS3 compliant?

A: Yes, both the IL252-X016 and H11AA4TVM are ROHS3 compliant, meeting modern environmental and supply chain requirements.

Q: What is the impact of the operating temperature range difference?

A: The IL252-X016 operates from -55°C to 100°C, while the H11AA4TVM operates from -40°C to 100°C. If your application requires operation below -40°C, the H11AA4TVM is not suitable. Verify your system's minimum operating temperature specification.

Q: Are the electrical characteristics identical between these components?

A: The components share identical current transfer ratio (100% @ 10mA), maximum output voltage (30V), Vce saturation (400mV), and maximum forward current (60mA) specifications. The primary electrical difference is isolation voltage: 5300Vrms versus 4170Vrms.

Q: What does "transistor with base output" mean for substitution purposes?

A: Both components feature a transistor output stage with accessible base connection, enabling direct circuit compatibility. This output configuration is essential for applications requiring base-driven control. Substitutes must maintain this output type.
