TIL111300 Optoisolator Equivalent & Substitute Parts

Part Overview

The TIL111300 is a 6-DIP optoisolator with transistor output and base connection, manufactured by onsemi. This component provides 5300Vrms isolation and is designed for applications requiring galvanic isolation with transistor-based switching capability. The TIL111300 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TIL111300 is determined by the following critical parameters:

• Package compatibility: 6-DIP (0.300", 7.62mm) through-hole mounting
• Output configuration: Transistor with base connection
• Isolation voltage: Minimum 5300Vrms or equivalent peak voltage rating
• Output characteristics: Maximum 30V output, 2mA per channel
• Input type: DC input
• Operating temperature range: Must support the required application temperature window
• Single channel: 1-channel configuration

The TIL111300 has two identified substitutes within the onsemi TIL111 family:

Direct Substitute - TIL111VM: Active product with higher isolation voltage (7500Vpk), identical package, and compatible electrical characteristics. Suitable for direct replacement in new designs.

Similar Substitute - TIL111: Base model with identical isolation voltage (5300Vrms) and electrical specifications to the TIL111300. Obsolete status limits availability but maintains full parameter compatibility.

Parameter Comparison

Engineering Selection Recommendations

TIL111VM is the primary substitute for new designs. As an active product with ROHS3 compliance, it provides long-term availability and regulatory alignment. The higher isolation voltage (7500Vpk versus 5300Vrms) offers enhanced safety margins in isolation-critical applications. The reduced maximum forward current (60mA versus 100mA) and narrower operating temperature range (-40°C to 100°C versus -55°C to 100°C) must be evaluated against specific application requirements.

TIL111 maintains identical electrical and thermal specifications to the TIL111300 but shares obsolete status, limiting its viability for sustained production. This part is suitable only where existing inventory is available and long-term supply is not required.

Frequently Asked Questions (FAQ)

Q: Can TIL111VM directly replace TIL111300 in existing designs?

A: Yes. Both parts share identical package geometry (6-DIP), output configuration (transistor with base), and critical electrical parameters (30V max output, 2mA per channel, 400mV Vce saturation, 10µs rise/fall time). The higher isolation voltage of TIL111VM (7500Vpk) is compatible with applications designed for 5300Vrms isolation.

Q: What is the difference between 5300Vrms and 7500Vpk isolation ratings?

A: These represent different measurement standards for isolation voltage. Both ratings indicate the maximum voltage that can be safely applied across the isolation barrier. The TIL111VM's 7500Vpk rating provides equivalent or superior isolation performance compared to the TIL111300's 5300Vrms rating.

Q: Does the reduced maximum forward current of TIL111VM (60mA vs 100mA) affect compatibility?

A: The forward current specification applies to the LED input side of the optoisolator. If the application drives the LED with less than 60mA, no compatibility issue exists. Applications requiring more than 60mA forward current must be re-evaluated for the TIL111VM.

Q: Is TIL111VM suitable for applications requiring -55°C operation?

A: No. TIL111VM operates from -40°C to 100°C. Applications requiring -55°C minimum temperature must use TIL111300 or TIL111 if available, or select an alternative optoisolator family with extended low-temperature ratings.

Q: Are there any compliance differences between these parts?

A: TIL111VM is ROHS3 compliant, while TIL111300 and TIL111 compliance status is not specified. All three parts are REACH Unaffected. For applications subject to RoHS requirements, TIL111VM is the appropriate selection.

Q: Can TIL111 be used as a substitute?

A: TIL111 is electrically and mechanically identical to TIL111300 but shares obsolete status. It is suitable only where existing inventory is available and immediate replacement is not required. For new production, TIL111VM is the recommended substitute.
