H11AV1FM Equivalent & Substitute Parts

Part Overview

The H11AV1FM is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 4170Vrms isolation rating. This component features a single-channel configuration with transistor output and is packaged in a 6-SMD surface mount format. The H11AV1FM is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across isolation voltage, current transfer ratio, output characteristics, and thermal operating range.

Substitute Part Grouping Explanation

Substitute parts for the H11AV1FM are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Voltage - Isolation: Minimum 4170Vrms (equal or higher acceptable)
• Current Transfer Ratio: 100% to 300% @ 10mA range
• Output Type: Transistor with Base configuration
• Vce Saturation: Maximum 400mV
• Operating Temperature Range: Must encompass -40°C to 100°C minimum
• Input Type: DC
• Number of Channels: 1

Two substitute parts meet these criteria with varying package configurations and manufacturer sources. The H11AV1SM maintains identical electrical specifications and surface mount packaging. The H11AV1X provides higher isolation voltage (5300Vrms) with modified package format (6-DIP through-hole) and extended temperature range (-55°C to 100°C).

Parameter Comparison

Engineering Selection Recommendations

H11AV1SM (Fairchild Semiconductor): This substitute provides direct electrical and mechanical compatibility with the H11AV1FM. Both components share identical isolation voltage (4170Vrms), current transfer ratio specifications, output voltage ratings, and saturation characteristics. The H11AV1SM is classified as active product status, ensuring continued availability and supply chain stability. Surface mount packaging (6-SMD, Gull Wing) matches the original design footprint, requiring no PCB layout modifications. This substitute is the preferred choice for direct replacement in existing designs.

H11AV1X (Isocom Components 2004 LTD): This substitute offers enhanced isolation voltage (5300Vrms) and extended operating temperature range (-55°C to 100°C), providing additional design margin for demanding applications. However, the through-hole 6-DIP package format differs from the surface mount configuration of the H11AV1FM, requiring PCB redesign and assembly process changes. The H11AV1X is suitable for new designs where package format flexibility exists and enhanced isolation performance is beneficial. RoHS3 compliance status is documented for this part.

Frequently Asked Questions (FAQ)

Q: Can H11AV1SM be used as a direct replacement for H11AV1FM without PCB modifications?

A: Yes. The H11AV1SM maintains identical electrical specifications (4170Vrms isolation, 100-300% current transfer ratio, 400mV Vce saturation) and surface mount packaging (6-SMD, Gull Wing). No circuit design changes or PCB layout modifications are required.

Q: What are the key differences between H11AV1SM and H11AV1X substitutes?

A: The H11AV1SM provides direct package and electrical compatibility with identical 4170Vrms isolation voltage and surface mount format. The H11AV1X offers higher isolation voltage (5300Vrms) and extended temperature range (-55°C to 100°C) but requires through-hole mounting (6-DIP package), necessitating PCB redesign.

Q: Is the H11AV1X suitable for applications requiring the original H11AV1FM specifications?

A: The H11AV1X meets all core electrical requirements (transistor output, 100-300% current transfer ratio, 400mV Vce saturation, 70V output voltage). However, the different package format (6-DIP through-hole versus 6-SMD surface mount) requires PCB layout changes and assembly process modifications.

Q: What is the impact of the H11AV1FM obsolescence status?

A: The H11AV1FM is classified as obsolete, meaning onsemi no longer manufactures or supports this component. Active substitute parts (H11AV1SM and H11AV1X) ensure continued availability and supply chain reliability for new production and design updates.

Q: Are there compliance or certification differences between the substitute parts?

A: The H11AV1X is documented as ROHS3 compliant. Compliance documentation for H11AV1SM is not specified in available data. Both substitute parts carry EAR99 ECCN classification and REACH Unaffected status, matching the original H11AV1FM.

Q: Which substitute part should be selected for new designs?

A: For new designs, H11AV1SM is recommended if surface mount packaging and 4170Vrms isolation voltage meet application requirements. H11AV1X is suitable if enhanced isolation voltage (5300Vrms) or extended temperature range (-55°C to 100°C) provides design advantages and through-hole mounting is acceptable.
