TIL113W Equivalent & Substitute Parts

Part Overview

The TIL113W is an optoisolator with Darlington output and base connection, rated for 5300Vrms isolation voltage. Manufactured by onsemi, this component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring similar functionality.

The TIL113W provides galvanic isolation between input and output circuits with a single channel configuration, suitable for applications requiring high voltage isolation with Darlington output topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TIL113W are qualified based on the following criteria:

• Single channel Darlington output optoisolator configuration
• 6-DIP through-hole package matching 0.400" (10.16mm) spacing
• Isolation voltage rated at 5000Vrms or higher
• Current transfer ratio minimum of 300% @ 10mA
• Operating temperature range of -55°C to 100°C
• DC input type with Darlington output topology including base connection
• Vce saturation characteristics compatible with 1.2V to 1.25V range

The TIL113M and TIL113G meet these substitution criteria with variations in maximum output voltage and switching characteristics.

Parameter Comparison

Engineering Selection Recommendations

TIL113M (Fairchild Semiconductor) is an active product with documented availability and meets all core substitution parameters. This part provides higher maximum output voltage (55V vs 30V) and equivalent Vce saturation performance. Fairchild Semiconductor components maintain standard industry compliance certifications.

TIL113G (Isocom Components 2004 LTD) is an active product with matching isolation voltage (5300Vrms) and output voltage specifications (30V). This part carries RoHS3 compliance certification and is supplied in tube packaging. Current transfer ratio specifications are not provided for this variant.

Both substitute parts maintain the 6-DIP package footprint and operating temperature range of the original TIL113W, enabling direct socket compatibility in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can TIL113M replace TIL113W in all applications?

A: TIL113M is electrically compatible for applications operating at output voltages up to 30V. The higher maximum output voltage rating (55V) of TIL113M does not affect compatibility in lower voltage circuits. Verify that your application does not depend on the specific switching time characteristics (TIL113W: 350ns turn-on, 55µs turn-off vs TIL113M: 5µs turn-on, 100µs maximum turn-off).

Q: What is the difference between TIL113M and TIL113G?

A: Both parts share the same 6-DIP package and operating temperature range. TIL113M specifies a 300% minimum current transfer ratio at 10mA, while TIL113G does not provide this specification. TIL113G provides rise and fall time data (60µs, 53µs) not specified for TIL113M. TIL113G carries RoHS3 compliance; TIL113M compliance status is not documented in provided data.

Q: Are there package compatibility concerns?

A: All three parts use identical 6-DIP (0.400", 10.16mm) through-hole packages. Direct socket substitution is mechanically feasible without PCB redesign.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For maximum output voltage headroom, TIL113M provides 55V capability. For matching original isolation voltage and output specifications with RoHS3 compliance, TIL113G is suitable. Both parts are active products with documented availability.
