Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11L2FM is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 4170Vrms (primary isolation specification)
• Number of Channels: 1 (single channel configuration)
• Output Type: Open Collector (logic output architecture)
• Data Rate: 1MHz (signal bandwidth requirement)
• Current - Output / Channel: 50 mA (load drive capability)
• Propagation Delay: 4µs maximum (timing specification)
• Rise / Fall Time: 100ns typical (signal integrity requirement)
• Voltage - Supply: 3V ~ 15V (operating voltage range)
• Operating Temperature: -40°C ~ 85°C (thermal operating range)
• Package / Case: 6-SMD, Gull Wing (physical form factor)

The H11L2SM meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The H11L2SM is the direct substitute for the H11L2FM. Both parts share identical electrical and mechanical specifications across all critical parameters. The H11L2SM is classified as Active product status, ensuring continued availability and manufacturing support. The H11L2SM is RoHS3 compliant, providing regulatory advantage over the obsolete H11L2FM. Both parts carry REACH Unaffected status and EAR99 export classification. The H11L2SM is supplied in Tube packaging format, whereas the H11L2FM packaging format is not specified. For new designs or production transitions, the H11L2SM is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can H11L2SM directly replace H11L2FM in existing designs?

A: Yes. The H11L2SM is electrically and mechanically equivalent to the H11L2FM across all specified parameters, including isolation voltage, output current, data rate, propagation delay, and package form factor.

Q: What is the primary reason to transition from H11L2FM to H11L2SM?

A: The H11L2FM is classified as obsolete, while the H11L2SM is active product. This ensures long-term availability, manufacturing continuity, and regulatory compliance for ongoing applications.

Q: Are there packaging differences between these parts?

A: The H11L2SM is supplied in Tube packaging. The H11L2FM packaging format is not specified in available documentation. Both parts use identical 6-SMD, Gull Wing surface mount packages.

Q: Does the H11L2SM meet current regulatory requirements?

A: Yes. The H11L2SM is RoHS3 compliant and carries REACH Unaffected status, meeting current regulatory standards for electronic components.

Q: Are the electrical characteristics identical between H11L2FM and H11L2SM?

A: Yes. Both parts specify identical isolation voltage (4170Vrms), output current (50 mA), data rate (1MHz), propagation delay (4µs), rise/fall time (100ns), supply voltage range (3V ~ 15V), and operating temperature range (-40°C ~ 85°C).
