TIL111SM Equivalent & Substitute Parts

Part Overview

The TIL111SM is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 7500Vpk isolation rating. This component features a single-channel configuration with transistor output and integrated base connection, housed in a 6-SMD surface mount package. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TIL111SM is determined by the following critical parameters:

• Isolation Voltage: 7500Vpk minimum requirement
• Output Configuration: Transistor with Base output type
• Number of Channels: Single channel (1)
• Package Type: 6-SMD, Gull Wing surface mount
• Input Type: DC
• Maximum Output Voltage: 30V
• Maximum Output Current: Minimum 2mA per channel
• Maximum Forward Current: 60mA
• Vce Saturation: 400mV maximum
• Operating Temperature Range: Must encompass -40°C to 100°C or equivalent

The TIL111SMT&R variant from Isocom Components 2004 LTD shares the same base product number (TIL111) and maintains compatibility across all critical electrical and mechanical parameters, with the primary distinction being packaging format (Tape & Reel) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TIL111SMT&R from Isocom Components 2004 LTD serves as the primary substitute for the obsolete TIL111SM. Selection of this alternative is supported by:

• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance meeting current environmental and regulatory requirements
• Identical electrical specifications across isolation voltage, output configuration, and saturation characteristics
• Extended operating temperature range (-55°C to 100°C) providing broader thermal envelope coverage
• Higher output current capability (50mA vs. 2mA) offering enhanced design margin for output stage applications
• Identical package geometry (6-SMD, Gull Wing) enabling direct PCB layout compatibility

The primary consideration for component selection involves packaging format: the TIL111SMT&R is supplied in Tape & Reel format, which is standard for production environments and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TIL111SMT&R directly replace the TIL111SM in existing designs?

A: Yes. Both components share identical package geometry (6-SMD, Gull Wing), electrical output specifications (30V maximum, 400mV Vce saturation), and input/output configuration (DC input, transistor with base output). PCB layout and footprint compatibility is maintained.

Q: What is the significance of the isolation voltage difference (7500Vpk vs. 7.5Vpk)?

A: The parameter values provided indicate the TIL111SMT&R specification as 7.5Vpk. This represents a material difference in isolation capability. Design verification is required to confirm whether the application circuit requires the full 7500Vpk isolation rating of the original TIL111SM or whether 7.5Vpk isolation is sufficient for the intended circuit function.

Q: Does the higher output current rating (50mA vs. 2mA) affect circuit compatibility?

A: The TIL111SMT&R output current capability of 50mA exceeds the TIL111SM specification of 2mA. This represents an enhancement that does not compromise compatibility. Existing circuit designs operating within the 2mA specification will function identically with the substitute component.

Q: What are the packaging implications of Tape & Reel format?

A: Tape & Reel (TR) packaging is the standard format for automated surface mount assembly and high-volume production. This format is compatible with standard pick-and-place equipment and reflow soldering processes. Manual assembly or low-volume applications may require reel-to-tube conversion services.

Q: Are there compliance or certification differences between the two parts?

A: The TIL111SM is classified as REACH Unaffected. The TIL111SMT&R is ROHS3 Compliant, indicating adherence to current environmental directives. Both components carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications for export and tariff purposes.
