TIL117TVM Optoisolator Equivalent & Substitute Parts

Part Overview

The TIL117TVM is a single-channel optoisolator with transistor output and base connection, manufactured by onsemi. It provides 7500Vpk isolation voltage in a 6-DIP through-hole package. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring similar functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TIL117TVM is determined by the following critical parameters:

• Package compatibility: 6-DIP (0.400", 10.16mm) through-hole mounting
• Output configuration: Transistor with base connection
• Input type: DC
• Isolation voltage: Minimum 5000V (acceptable reduction from 7500Vpk)
• Current transfer ratio: Minimum 50% @ 10mA preferred; lower ratios acceptable with circuit design adjustment
• Output voltage rating: Minimum 30V
• Vce saturation: 400mV maximum
• Forward voltage (Vf): 1.2V typical
• Maximum forward current: 60mA DC

Substitute parts are grouped by isolation voltage capability and current transfer ratio performance. Active product status and RoHS3 compliance are preferred for new designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TIL117G

TIL117G is the direct equivalent from Isocom Components. It maintains the same isolation voltage (7.5Vpk), current transfer ratio (50% @ 10mA), output voltage rating (30V), and rise/fall time characteristics (2µs, 2µs) as the TIL117TVM. It is actively produced and RoHS3 compliant, making it the preferred choice for direct replacement in existing designs.

Secondary Substitutes: H11A5M-V, LTV-702VM

For applications where reduced isolation voltage is acceptable, H11A5M-V and LTV-702VM provide active product status and RoHS3 compliance. H11A5M-V offers 30% current transfer ratio with 5000Vrms isolation. LTV-702VM provides 40% to 320% current transfer ratio range with 5000Vrms isolation and specified current output of 50mA. Both support extended operating temperature ranges (-55°C to 110°C or -55°C to 100°C).

Tertiary Substitutes: H11A2M-V, H11A3M-V, H11A4M-V

These Everlight parts provide 5000Vrms isolation with varying current transfer ratios (20%, 20%, and 10% respectively). They are suitable for applications with lower current transfer ratio requirements and extended temperature operation. All are RoHS3 compliant and actively produced.

Isolation Voltage Consideration

The TIL117TVM specifies 7500Vpk isolation. Substitute parts with 5000Vrms isolation represent a reduction in isolation capability. Circuit design must confirm that 5000Vrms meets system isolation requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can H11A2M-V, H11A3M-V, or H11A4M-V replace TIL117TVM directly?

A: These parts are mechanically and functionally compatible (same 6-DIP package, transistor output with base, DC input). However, they provide 5000Vrms isolation versus the TIL117TVM's 7500Vpk. Circuit design must confirm that reduced isolation voltage is acceptable for the application. Current transfer ratios are lower (10–20% versus 50%), requiring circuit adjustment if higher gain is required.

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

A: Vpk (peak voltage) and Vrms (RMS voltage) are different measurement standards for isolation voltage. Direct comparison requires understanding the specific isolation test methodology used by each manufacturer. The TIL117TVM uses Vpk; substitute parts use Vrms. System isolation requirements must be evaluated against both specifications.

Q: Is TIL117G a direct replacement for TIL117TVM?

A: Yes. TIL117G maintains the same isolation voltage (7.5Vpk), current transfer ratio (50% @ 10mA), output voltage (30V), and switching characteristics (2µs rise/fall time). It is actively produced and RoHS3 compliant. Pin configuration and package dimensions are identical.

Q: Can I use LTV-702VM if my circuit requires higher output current?

A: LTV-702VM specifies 50mA current output per channel, compared to the TIL117TVM which does not specify this parameter. If your circuit requires 50mA output capability, LTV-702VM is suitable. However, isolation voltage is reduced to 5000Vrms, which must be confirmed acceptable for your application.

Q: What is the impact of different current transfer ratios on circuit design?

A: Current transfer ratio determines the output current relative to input current. The TIL117TVM specifies 50% minimum. Substitutes with lower ratios (10–40%) require higher input current to achieve the same output current. Circuit input drive capability must be evaluated before selection.

Q: Are all substitute parts RoHS3 compliant?

A: TIL117G, H11A2M-V, H11A3M-V, H11A4M-V, and LTV-702VM are all RoHS3 compliant. The original TIL117TVM does not specify RoHS status. For new designs subject to RoHS requirements, all listed substitutes are suitable.

Q: What is the operating temperature range difference?

A: The TIL117TVM operates from -40°C to 100°C. Most substitutes extend the lower limit to -55°C and upper limit to 110°C (Everlight parts) or 100°C (Lite-On and Isocom). Extended temperature range provides greater design flexibility for industrial and automotive applications.
