TIL113S Equivalent & Substitute Parts

Part Overview

The TIL113S is an optoisolator with Darlington output and base connection, manufactured by onsemi. This component provides 5300Vrms isolation in a 6-SMD surface mount package. The TIL113S is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TIL113S is determined by the following critical parameters:

• Isolation Voltage: Minimum 5300Vrms (equal or greater)
• Output Configuration: Darlington with Base
• Number of Channels: 1 channel
• Package Type: 6-SMD, Gull Wing surface mount
• Input Type: DC
• Maximum Output Voltage: 30V or greater
• Operating Temperature Range: Must encompass or match -55°C ~ 100°C
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Two substitute parts are identified:

Direct Equivalent: TIL113SM (onsemi) — Active product with identical base design but reduced isolation voltage (4170Vrms). Suitable where lower isolation voltage is acceptable.

Similar Alternative: TIL113SMT&R (Isocom Components 2004 LTD) — Active product with matching isolation voltage (5300Vrms) and identical package, supplied in Tape & Reel format.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring 5300Vrms isolation: TIL113SMT&R is the primary substitute. It maintains the full isolation voltage specification of the obsolete TIL113S, operates across the identical temperature range (-55°C ~ 100°C), and is supplied as an active product. The Tape & Reel packaging format is standard for production environments.

For applications tolerating 4170Vrms isolation: TIL113SM is an alternative from the same manufacturer (onsemi). This part is active and RoHS3 compliant. The reduced isolation voltage and narrower operating temperature range (-40°C ~ 100°C) must be evaluated against circuit requirements. Higher output current capability (150mA vs. 30mA in TIL113SMT&R) may provide design flexibility.

Both substitute parts maintain the Darlington with Base output configuration, 6-SMD Gull Wing package, and MSL 1 rating. All parts carry REACH Unaffected status and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can TIL113SM replace TIL113S directly?

A: TIL113SM is functionally compatible in package and output type but operates at 4170Vrms isolation versus the TIL113S specification of 5300Vrms. Substitution is valid only if circuit isolation requirements do not exceed 4170Vrms. The operating temperature range is also narrower (-40°C ~ 100°C vs. -55°C ~ 100°C).

Q: What is the difference between TIL113SM and TIL113SMT&R?

A: Both are onsemi-derived designs. TIL113SM is supplied in Bulk packaging, while TIL113SMT&R is supplied in Tape & Reel format. TIL113SMT&R is manufactured by Isocom Components 2004 LTD and maintains the full 5300Vrms isolation voltage. TIL113SM has reduced isolation voltage (4170Vrms) but higher output current (150mA).

Q: Are all substitute parts RoHS compliant?

A: TIL113SM and TIL113SMT&R are both ROHS3 compliant. The original TIL113S RoHS status is not specified in the provided data.

Q: Does packaging format affect electrical performance?

A: No. Bulk and Tape & Reel packaging formats contain identical components. The format difference reflects supply chain and assembly process requirements only.

Q: What is the minimum isolation voltage I can accept?

A: This depends on your circuit design. The TIL113S specifies 5300Vrms. If your application requires this full isolation rating, use TIL113SMT&R. If your design allows 4170Vrms, TIL113SM is acceptable.
