Frequently Asked Questions (FAQ)

Q: Can TLE2426CD replace TLE2426CDG4 in existing designs?

A: Yes. The TLE2426CD is electrically and mechanically equivalent to the TLE2426CDG4. All electrical parameters, including output voltage range (2V to 20V), output current (20 mA), tolerance (±1%), and package specifications (8-SOIC) are identical. Direct substitution is possible without circuit modification.

Q: Are there any package or pinout differences between these parts?

A: No. Both the TLE2426CDG4 and TLE2426CD use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). Pinout and mounting requirements are identical for surface-mount applications.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy indicates that the TLE2426CDG4 will not be manufactured beyond a specified date. Identifying and qualifying the TLE2426CD as a substitute ensures supply continuity for new production runs and future design iterations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TLE2426CDG4 and TLE2426CD are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements for environmental and hazardous substance restrictions.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is based on matching: reference type (Ground Reference Virtual), output type (Adjustable), voltage range (2V to 20V), output current (20 mA), tolerance (±1%), temperature coefficient (35ppm/°C), noise performance (120µVrms), input voltage range (4V to 40V), and operating temperature range (0°C to 70°C).
