Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIL113SM optoisolator is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 4170Vrms minimum
• Number of Channels: 1 channel configuration
• Output Configuration: Darlington with Base output stage
• Current Transfer Ratio: 300% @ 10mA minimum
• Maximum Output Current: 150mA per channel
• Maximum Output Voltage: 30V
• Package Type: 6-SMD, Gull Wing surface mount
• Input Type: DC
• Operating Temperature Range: -40°C to 100°C minimum

Components meeting all these parameters are considered direct equivalents. The TIL113SM base product number serves as the reference for this substitution group.

Parameter Comparison

Engineering Selection Recommendations

The TIL113SM is an active product with full ROHS3 compliance and REACH unaffected status, making it suitable for current design implementations. The component carries MSL Level 1 classification, indicating unlimited shelf life without moisture sensitivity constraints.

Selection of equivalent parts should prioritize components with identical isolation voltage rating (4170Vrms), matching Darlington output configuration with base connection, and equivalent current transfer ratio performance. The 6-SMD Gull Wing package format is critical for PCB assembly compatibility and must be maintained in any substitution decision.

Compliance certifications (ROHS3, REACH unaffected) and regulatory classifications (ECCN: EAR99, HTSUS: 8541.49.8000) should be verified for the substitute component to ensure regulatory alignment with the original design specification.

Frequently Asked Questions (FAQ)

Q: What defines a direct equivalent for the TIL113SM? A: A direct equivalent must match all critical parameters: 4170Vrms isolation voltage, single channel Darlington with base output, 300% minimum current transfer ratio, 150mA output current capability, 30V maximum output voltage, and 6-SMD Gull Wing package configuration.

Q: Can the TIL113SM be substituted with a different output type optoisolator? A: No. The Darlington with base output configuration is specific to this device. Substitutes with different output stages (open collector, photodiode, or triac output) are not compatible and will not function as intended in the circuit.

Q: Is the 6-SMD package interchangeable with other package formats? A: No. The 6-SMD Gull Wing package is specific to this component family. Different package types require PCB redesign and are not considered direct substitutes.

Q: What is the significance of the 4170Vrms isolation rating? A: The isolation voltage rating determines the maximum voltage differential that can be safely applied across the optoisolator's isolation barrier. Substitutes must meet or exceed this specification to maintain circuit safety and reliability.

Q: Are there any temperature range considerations for substitution? A: Yes. The operating temperature range of -40°C to 100°C must be maintained in any substitute component. Applications requiring extended temperature operation require components with expanded temperature specifications.

Q: What does MSL Level 1 mean for component handling? A: MSL Level 1 indicates unlimited moisture sensitivity level, meaning the component has no moisture-related shelf life limitations and does not require special storage or baking procedures prior to assembly.
