H11N1FVM Equivalent & Substitute Parts

Part Overview

The H11N1FVM is a logic output optoisolator manufactured by onsemi, designed for high-voltage isolation applications requiring 4170Vrms isolation rating. This component features a single channel with open collector output, 5MHz data rate capability, and operates across a -40°C to 85°C temperature range. The H11N1FVM is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11N1FVM is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 4170Vrms (exact match required)
• Number of Channels: 1 channel (exact match required)
• Output Configuration: Open Collector topology (exact match required)
• Output Current Rating: 50 mA per channel (exact match required)
• Data Rate: 5MHz (exact match required)
• Propagation Delay: 330ns maximum for both tpLH and tpHL (exact match required)
• Supply Voltage Range: 4V ~ 15V (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 6-SMD, Gull Wing surface mount (exact match required)

The H11N1SVM meets all substitution criteria as a direct functional equivalent, with identical electrical specifications and mechanical compatibility.
