Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11L13SD is determined by the following critical parameters:

• Isolation Voltage: The H11L13SD specifies 5300Vrms isolation. The substitute H11L1SR2VM provides 4170Vrms isolation, representing a 21% reduction in isolation capability.
• Output Configuration: Both parts feature open collector output with 50mA per channel capacity.
• Data Rate: Both parts operate at 1MHz maximum data rate.
• Package Type: Both parts use 6-SMD, Gull Wing surface mount packaging, ensuring mechanical and electrical compatibility.
• Input Type: Both parts accept DC input signals.
• Channel Count: Both parts provide single-channel isolation.

The H11L1SR2VM qualifies as a substitute where the reduced isolation voltage of 4170Vrms meets application requirements. This part is currently in active production status with improved compliance characteristics.

Engineering Selection Recommendations

The H11L1SR2VM serves as the primary substitute for the obsolete H11L13SD. Selection of this substitute is supported by the following factors:

• Product Status: The H11L1SR2VM maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete H11L13SD.
• Regulatory Compliance: The H11L1SR2VM achieves ROHS3 compliance, whereas the H11L13SD is RoHS non-compliant. This compliance improvement aligns with current manufacturing and environmental regulations.
• Isolation Voltage Consideration: Applications requiring the full 5300Vrms isolation specification of the H11L13SD cannot use the H11L1SR2VM without circuit redesign. The 4170Vrms rating of the substitute represents a lower isolation tier suitable for applications with reduced isolation requirements.
• Electrical Characteristics: Both parts maintain identical output current (50mA), data rate (1MHz), and package configuration, enabling direct mechanical substitution in compatible applications.

Frequently Asked Questions (FAQ)

Q: Can the H11L1SR2VM directly replace the H11L13SD in all applications?

A: Direct replacement is possible only in applications where the isolation voltage requirement does not exceed 4170Vrms. Applications specifically designed for 5300Vrms isolation require circuit evaluation before substitution.

Q: What is the primary advantage of using H11L1SR2VM over H11L13SD?

A: The H11L1SR2VM is in active production with ROHS3 compliance certification, whereas the H11L13SD is obsolete and RoHS non-compliant. This ensures supply availability and regulatory alignment for new designs and ongoing production.

Q: Are the package dimensions identical between these parts?

A: Both parts use 6-SMD, Gull Wing surface mount packaging. Mechanical compatibility is maintained for PCB layout and assembly processes.

Q: What is the difference in forward current specifications?

A: The H11L13SD specifies maximum DC forward current of 1.6mA, while the H11L1SR2VM specifies 30mA. The H11L1SR2VM provides higher input current capability, allowing operation with higher input drive currents.

Q: Is the H11L1SR2VM suitable for high-voltage isolation applications?

A: The H11L1SR2VM provides 4170Vrms isolation, suitable for industrial and consumer applications with standard isolation requirements. Applications requiring isolation above 4170Vrms require alternative component selection.
