H11AV2AM Equivalent & Substitute Parts

Part Overview

The H11AV2AM 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 in a 6-DIP through-hole package and is classified as obsolete. Due to its obsolete status, identifying functionally compatible substitute parts is essential for ongoing system maintenance, redesign efforts, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The CNY173SM is identified as a substitute for the H11AV2AM based on the following substitution criteria:

Matching Parameters:

• Single-channel optoisolator configuration
• Transistor with base output topology
• Maximum output voltage of 70V
• Vce saturation maximum of 400mV
• Operating temperature range of -40°C ~ 100°C
• Moisture sensitivity level 1 (Unlimited)
• Same manufacturer (onsemi)
• Same ECCN and HTSUS classifications

Differing Parameters:

• Isolation voltage: CNY173SM provides 4170Vrms (lower than H11AV2AM's 7500Vpk)
• Current transfer ratio: CNY173SM offers 100-200% @ 10mA (higher than H11AV2AM's 50% minimum)
• Switching speed: CNY173SM has faster turn-on/turn-off times (2µs/3µs vs. 15µs/15µs)
• Mounting type: CNY173SM is surface mount (6-SMD) versus through-hole for H11AV2AM
• Product status: CNY173SM is active

Substitution is valid when isolation voltage requirements do not exceed 4170Vrms and when surface-mount packaging is acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

The CNY173SM serves as a functional substitute for the H11AV2AM under the following conditions:

Isolation Voltage Compatibility: Applications requiring isolation voltages up to 4170Vrms can utilize the CNY173SM. Systems designed for the H11AV2AM's 7500Vpk isolation capability must retain the original part or identify alternatives with equivalent or higher isolation ratings.

Packaging Considerations: The transition from 6-DIP through-hole to 6-SMD surface-mount requires PCB redesign. This substitution is practical for new designs or board revisions but not for direct socket replacement in existing through-hole layouts.

Performance Enhancement: The CNY173SM provides superior switching characteristics (2µs/3µs turn-on/turn-off versus 15µs/15µs) and higher current transfer ratio (100-200% versus 50% minimum), which may improve system performance in applications tolerant of lower isolation voltage.

Compliance and Availability: The CNY173SM is an active product with current manufacturing status, ensuring long-term availability and supply chain stability. Both parts share identical ECCN (EAR99), HTSUS (8541.49.8000), and REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can the CNY173SM directly replace the H11AV2AM in existing PCBs?

A: Direct socket replacement is not possible due to different package types. The H11AV2AM uses 6-DIP through-hole mounting, while the CNY173SM uses 6-SMD surface-mount. PCB redesign is required for substitution.

Q: What is the primary limitation of using CNY173SM as a substitute?

A: The CNY173SM provides 4170Vrms isolation voltage, which is lower than the H11AV2AM's 7500Vpk rating. Applications requiring higher isolation voltage must use alternative parts with equivalent or superior isolation specifications.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share identical ECCN, HTSUS, and REACH compliance classifications. The CNY173SM includes RoHS3 compliance, while the H11AV2AM's RoHS status is not specified in the provided data.

Q: What are the advantages of the CNY173SM over the H11AV2AM?

A: The CNY173SM offers faster switching times (2µs/3µs versus 15µs/15µs), higher current transfer ratio (100-200% versus 50% minimum), and active product status ensuring ongoing availability and support.

Q: Is the CNY173SM suitable for high-speed switching applications?

A: Yes. The CNY173SM's 2µs turn-on and 3µs turn-off times make it suitable for applications requiring faster response compared to the H11AV2AM's 15µs switching characteristics.

Q: What packaging options are available for through-hole applications if CNY173SM is unsuitable?

A: The provided data includes only the CNY173SM as a documented substitute. For through-hole package requirements, consult the H11A base product family or equivalent optoisolator series with 6-DIP packaging.
