• Input Voltage Range: 4V ~ 40V
• Supply Current: 400 µA
• Operating Temperature Range: 0°C ~ 70°C
• Package: TO-92-3
• Compliance: ROHS3 Compliant

The TLE2426CLP meets all specified electrical and mechanical parameters and is classified as a parametric equivalent. Both parts share the same base product number (TLE2426) and are manufactured by Texas Instruments, ensuring functional interchangeability within the defined parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

The TLE2426CLP is a direct parametric equivalent to the TLE2426CLPE3. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are packaged in the same TO-92-3 configuration. Both parts maintain ROHS3 compliance and are classified as Last Time Buy products.

Selection between these parts should be based on inventory availability and supply chain considerations. The TLE2426CLPE3 currently has 1957 units in stock, while the TLE2426CLP has 1489 units available. For applications requiring long-term supply assurance, either part may be selected without modification to circuit design or PCB layout, as they are functionally and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the TLE2426CLP be used as a direct replacement for the TLE2426CLPE3?

A: Yes. The TLE2426CLP is a parametric equivalent with identical electrical specifications, output characteristics, input requirements, and package configuration. No circuit modifications are required.

Q: Are there any differences in the TO-92-3 package between these parts?

A: No. Both parts use the same TO-226-3 / TO-92-3 (TO-226AA) package specification. Pin configuration and mechanical dimensions are identical, allowing direct PCB substitution.

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

A: Last Time Buy indicates that Texas Instruments will discontinue production of these parts. Existing inventory represents the final availability. For long-term production requirements, alternative voltage reference solutions should be evaluated in parallel with current stock utilization.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLE2426CLPE3 and TLE2426CLP are ROHS3 compliant and meet environmental regulatory requirements for electronic component manufacturing and use.

Q: What are the critical parameters that define substitutability for this part?

A: Substitutability is determined by: reference type (ground reference virtual), output type (adjustable), voltage range (2V to 20V), output current (20 mA), tolerance (±1%), temperature coefficient (35 ppm/°C), noise specification (120 µVrms), input voltage range (4V to 40V), supply current (400 µA), operating temperature range (0°C to 70°C), and package type (TO-92-3). Any deviation in these parameters disqualifies a part as a direct substitute.
