H11L1TM Equivalent & Substitute Parts

Part Overview

The H11L1TM 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, 1MHz data rate capability, and operates across a -40°C to 85°C temperature range. The H11L1TM is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11L1TM is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 4170Vrms (exact match required)
• Number of Channels: 1 channel configuration
• Output Type: Open collector topology
• Output Current Rating: 50 mA per channel
• Data Rate: 1MHz minimum
• Propagation Delay: 4µs maximum (tpLH and tpHL)
• Supply Voltage Range: 3V ~ 15V compatibility
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 6-DIP through-hole mounting
• Input Type: DC input

The H11L1TVM meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent despite differences in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The H11L1TVM is the direct substitute for the H11L1TM based on complete electrical and mechanical parameter equivalence. The primary distinction is product status: the H11L1TM is obsolete while the H11L1TVM maintains active status with onsemi. Both components carry identical REACH and ECCN classifications, confirming regulatory equivalence. The H11L1TVM is supplied in tube packaging, whereas the H11L1TM packaging specification is not detailed. Both components are RoHS compliant or unaffected by RoHS requirements. Selection of the H11L1TVM for new designs or system replacements is supported by its active product status and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the H11L1TVM directly replace the H11L1TM in existing applications?

A: Yes. The H11L1TVM meets all electrical specifications of the H11L1TM, including isolation voltage (4170Vrms), output current (50 mA), data rate (1MHz), propagation delay (4µs), and supply voltage range (3V ~ 15V). Both components use identical 6-DIP through-hole packaging and operate across -40°C to 85°C.

Q: What is the primary reason for substitution?

A: The H11L1TM is classified as obsolete. The H11L1TVM is the active equivalent from the same manufacturer, ensuring continued availability and manufacturer support.

Q: Are there compliance differences between these parts?

A: No. Both components share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). Regulatory compliance is equivalent.

Q: Does packaging differ between the two parts?

A: The H11L1TVM is supplied in tube packaging. Both components use the same 6-DIP (0.400", 10.16mm) through-hole package format, ensuring mechanical compatibility in PCB designs.

Q: Are the timing characteristics identical?

A: Yes. Propagation delay (4µs maximum for both tpLH and tpHL), rise time (100ns typical), and fall time (100ns typical) are identical between the H11L1TM and H11L1TVM.
