H11AV2FVM Equivalent & Substitute Parts

Part Overview

The H11AV2FVM is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 7500Vpk isolation rating. This component features a single-channel configuration with transistor output and integrated base connection, suitable for DC input applications. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the H11AV2FVM is based on the following critical parameters that define functional equivalence:

• Single-channel optoisolator configuration
• Transistor output with base connection
• Minimum current transfer ratio of 50% @ 10mA
• Maximum output voltage of 70V
• Vce saturation maximum of 400mV
• DC input type
• Maximum forward current of 60mA
• Forward voltage in the range of 1.18V to 1.2V

The H11AV2X qualifies as a substitute part despite differences in isolation voltage rating (5300Vrms versus 7500Vpk) and packaging format (6-DIP through-hole versus 6-SMD surface mount), as it maintains all critical electrical parameters within acceptable tolerances for the optoisolator transistor with base output category.

Engineering Selection Recommendations

The H11AV2X represents an active product alternative to the obsolete H11AV2FVM. Selection between these components depends on system-level requirements:

Isolation Voltage Consideration: The H11AV2FVM provides 7500Vpk isolation, while the H11AV2X provides 5300Vrms isolation. Applications requiring the higher isolation specification of the main part cannot use the substitute without circuit redesign or isolation verification.

Mounting and Assembly: The H11AV2FVM uses surface-mount technology (6-SMD), while the H11AV2X uses through-hole technology (6-DIP). PCB layout and assembly process compatibility must be evaluated independently.

Compliance Status: The H11AV2X carries RoHS3 compliance certification, whereas the H11AV2FVM status is not specified. Both parts are REACH Unaffected and classified under ECCN EAR99.

Temperature Range: The H11AV2X supports an extended lower operating temperature (-55°C versus -40°C), providing broader environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the H11AV2X directly replace the H11AV2FVM in existing designs?

A: Direct replacement requires verification of isolation voltage requirements. If the application circuit design depends on the 7500Vpk isolation specification, the H11AV2X with 5300Vrms isolation is not suitable. Additionally, the different mounting technologies (surface mount versus through-hole) require PCB redesign.

Q: What are the critical electrical parameters that must match for substitution?

A: The following parameters must remain within specification: single-channel configuration, transistor output with base connection, minimum 50% current transfer ratio at 10mA, maximum 70V output voltage, 400mV maximum Vce saturation, and 60mA maximum forward current.

Q: How do the isolation voltage ratings compare?

A: The H11AV2FVM specifies 7500Vpk isolation, while the H11AV2X specifies 5300Vrms isolation. These represent different measurement standards and cannot be directly compared without conversion. Applications with high-voltage isolation requirements must confirm the H11AV2X meets the minimum isolation threshold.

Q: Are there packaging considerations for substitution?

A: Yes. The H11AV2FVM is a 6-SMD surface-mount component, while the H11AV2X is a 6-DIP through-hole component. PCB footprint, assembly equipment, and soldering process compatibility differ significantly between these package types.

Q: What is the inventory status of these parts?

A: The H11AV2FVM is obsolete with 1029 pieces available in current stock. The H11AV2X is an active product with 746 pieces available in current stock.
