TLP118(TPL,E)
Toshiba Semiconductor and Storage
Needs validationhigh risk
A form-fit compatible downgrade with lower speed and transient immunity. Recommended by the mfr for replacing this part, not the other way around.
Best Alternatives to TLP2368(TPL,E
The Toshiba TLP2368(TPL,E) is a 20MBd high-speed open-collector optocoupler in an SO6 package. Finding a replacement requires careful matching of its speed, transient immunity, and wide operating temperature.
AI replacement insight
Electrical riskhigh
Alternatives have lower data rates and/or weaker transient immunity (CMTI), which may affect system timing and reliability.
Package risklow
Several alternatives exist in the same SO6 5-pin package, suggesting good physical compatibility.
Sourcing risklow
The TLP23xx family from Toshiba offers several related parts, though none are a perfect match.
Can it be replaced directly?
No direct, drop-in replacement for the TLP2368(TPL,E) with identical or better performance was identified. Alternatives require careful review of performance trade-offs.
Best replacement path
The TLP2363 is a potential functional alternative if a lower data rate (15Mbps) and max temperature (105°C) are acceptable. No direct upgrade was found.
Main risk
The primary risk in replacing the TLP2368 is performance degradation, as most alternatives have lower data rates or narrower operating conditions.
