TLE2426ILP Equivalent & Substitute Parts
Part Overview
The TLE2426ILP is a ground reference (virtual) voltage reference IC from Texas Instruments, designed for adjustable output applications requiring precision voltage references. This device operates across a 4V to 40V input range with adjustable output from 2V to 20V, delivering up to 20mA output current with ±1% tolerance. The TLE2426ILP is classified as Last Time Buy, indicating limited future availability. Identifying equivalent and substitute parts is essential for design continuity and long-term supply chain planning.

Substitute Part Grouping Explanation
Substitution eligibility for the TLE2426ILP is determined by strict alignment across the following critical parameters:
- Reference Type: Ground Reference (Virtual)
- Output Type: Adjustable
- Voltage Output Range: 2V to 20V
- Output Current: 20mA
- Tolerance: ±1%
- Temperature Coefficient: 35ppm/°C Typical
- Noise Performance: 120µVrms (10Hz to 10kHz)
- Input Voltage Range: 4V ~ 40V
- Supply Current: 400µA
- Package: TO-92-3
- Mounting: Through Hole
- Compliance: ROHS3 Compliant
The TLE2426CLP qualifies as a manufacturer-recommended substitute, meeting all electrical and mechanical specifications. Operating temperature range differences do not preclude substitution when application requirements fall within the narrower temperature window of the substitute part.

Engineering Selection Recommendations
The TLE2426CLP is the manufacturer-recommended substitute for the TLE2426ILP. Both parts maintain identical electrical specifications across all critical parameters including output voltage range, current capacity, tolerance, temperature coefficient, and noise performance. Both devices are ROHS3 compliant and share the same TO-92-3 through-hole package.
The primary distinction is operating temperature range. The TLE2426ILP supports -40°C to 85°C, while the TLE2426CLP operates within 0°C to 70°C. Selection between these parts depends on application temperature requirements. For applications operating exclusively within 0°C to 70°C, the TLE2426CLP provides equivalent performance. For applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C, the TLE2426ILP is required.
Both parts carry Last Time Buy status, indicating limited future availability from the manufacturer. Long-term supply planning should account for this constraint.
Frequently Asked Questions (FAQ)
Q: Can TLE2426CLP replace TLE2426ILP in all applications?
A: The TLE2426CLP provides electrical equivalence across all specified parameters. Substitution is valid only when the application operates within the TLE2426CLP temperature range of 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must use the TLE2426ILP.
Q: Are the packages identical between TLE2426ILP and TLE2426CLP?
A: Yes. Both parts use the TO-92-3 (TO-226AA) through-hole package with identical pinout and mechanical dimensions. PCB layout and component placement require no modification for substitution.
Q: What is the significance of Last Time Buy status?
A: Last Time Buy indicates the manufacturer will not produce additional quantities beyond current inventory. Both the TLE2426ILP and TLE2426CLP carry this status. Design teams should evaluate long-term supply requirements and consider alternative voltage reference architectures if extended production timelines are anticipated.
Q: Are both parts RoHS compliant?
A: Yes. Both TLE2426ILP and TLE2426CLP are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
Q: Do the parts have identical noise performance?
A: Yes. Both parts specify 120µVrms noise in the 10Hz to 10kHz bandwidth, ensuring equivalent performance in noise-sensitive applications.
