TIL117FR2VM Equivalent & Substitute Parts

Part Overview

The TIL117FR2VM 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 with transistor output and base connection, housed in a 6-SMD surface mount package. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TIL117FR2VM is determined by the following critical parameters:

• Voltage - Isolation Rating: 7500Vpk minimum required
• Number of Channels: Single channel configuration
• Output Type: Transistor with Base output
• Current Transfer Ratio: 50% @ 10mA minimum
• Mounting Type: Surface Mount preferred for form factor compatibility
• Package Type: 6-SMD, Gull Wing for direct PCB compatibility

Substitute parts must maintain these electrical and mechanical specifications to ensure functional equivalence. Parts that deviate from these core parameters may require circuit redesign or board layout modifications.

Parameter Comparison

Engineering Selection Recommendations

TIL117SR2VM (Fairchild Semiconductor) is the primary direct substitute for TIL117FR2VM. Both parts maintain identical electrical specifications including 7500Vpk isolation voltage, 50% minimum current transfer ratio, and matching switching characteristics. The TIL117SR2VM is currently in active production status, ensuring supply chain availability. Both components use identical 6-SMD, Gull Wing surface mount packaging, enabling direct PCB replacement without layout modifications. Bulk packaging is available for the Fairchild variant.

TIL117 (Texas Instruments) serves as a secondary substitute option with important trade-offs. While maintaining the same output type and current transfer ratio, the TIL117 features a lower isolation voltage rating of 5000Vrms compared to the 7500Vpk requirement. Additionally, this part uses through-hole 6-DIP packaging rather than surface mount, requiring PCB redesign and board layout changes. The TIL117 offers extended operating temperature range (-55°C to 110°C) and higher maximum output voltage (80V). This option is suitable only when isolation voltage reduction and packaging conversion are acceptable for the application. The TIL117 is also obsolete.

For new designs and production continuity, TIL117SR2VM is the recommended equivalent. For applications where isolation voltage can be reduced and through-hole mounting is feasible, TIL117 provides an alternative path.

Frequently Asked Questions (FAQ)

Q: Can TIL117SR2VM replace TIL117FR2VM directly on the PCB?

A: Yes. Both parts share identical electrical specifications and 6-SMD, Gull Wing surface mount packaging. Direct PCB substitution is possible without layout modifications.

Q: What is the key difference between TIL117FR2VM and TIL117?

A: The primary differences are isolation voltage rating (7500Vpk vs. 5000Vrms), packaging type (6-SMD surface mount vs. 6-DIP through-hole), and maximum output voltage (30V vs. 80V). The TIL117 requires PCB redesign if substituted.

Q: Why is TIL117SR2VM preferred over TIL117?

A: TIL117SR2VM maintains the same isolation voltage specification and surface mount packaging as the original TIL117FR2VM, eliminating the need for circuit or board redesign. TIL117SR2VM is also in active production, ensuring supply availability.

Q: Are there any compliance or certification differences between these parts?

A: All three parts share the same ECCN (EAR99) and HTSUS (8541.49.8000) classifications. TIL117 is RoHS non-compliant, while TIL117FR2VM and TIL117SR2VM have REACH Unaffected status.

Q: Can I use TIL117 in a design requiring 7500Vpk isolation?

A: No. The TIL117 isolation rating of 5000Vrms is insufficient for applications requiring 7500Vpk isolation. Using this part would compromise isolation performance and safety margins.

Q: What packaging considerations apply when selecting a substitute?

A: TIL117FR2VM and TIL117SR2VM both use 6-SMD, Gull Wing surface mount packaging and are directly interchangeable on existing PCBs. TIL117 requires different board layout due to 6-DIP through-hole packaging, making it unsuitable for direct replacement without redesign.
