TLVH431ILPE3 Equivalent & Substitute Parts

Part Overview

The TLVH431ILPE3 is a shunt voltage reference IC manufactured by Texas Instruments, designed for adjustable voltage regulation applications. This component provides a fixed output of 1.24V with a maximum output of 18V and supports 70 mA output current. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The TLVH431ILPE3 operates across the industrial temperature range of -40°C to 85°C and is housed in a TO-92-3 through-hole package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLVH431ILPE3 is determined by strict equivalence across the following critical parameters:

Reference Type: Shunt voltage reference architecture must remain constant.

Output Type: Adjustable output configuration must be maintained.

Voltage Range: Output voltage specifications (1.24V minimum, 18V maximum) must be identical or exceed the original part requirements.

Current Rating: Output current capacity of 70 mA and cathode current of 100 µA must be met or exceeded.

Package Configuration: TO-92-3 through-hole package is required for mechanical and thermal compatibility.

Operating Temperature Range: -40°C to 85°C industrial range must be supported.

Compliance Standards: RoHS3 compliance and REACH unaffected status must be maintained.

The TLVH431AILP qualifies as a direct substitute based on these parameters. While tolerance improves to ±1% (compared to ±1.5% in the original), all other electrical and mechanical specifications remain equivalent or superior.

Parameter Comparison

Engineering Selection Recommendations

The TLVH431AILP is the qualified substitute for the obsolete TLVH431ILPE3. Both parts maintain identical electrical specifications across voltage output range, current capacity, and operating temperature. The substitute part offers improved tolerance performance at ±1% versus ±1.5%, providing enhanced voltage regulation accuracy without compromising any functional requirement.

From a procurement perspective, the TLVH431AILP carries Last Time Buy status, indicating limited future availability. The substitute maintains full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

Pin-to-pin compatibility and package equivalence (TO-92-3) enable direct board-level substitution without circuit redesign or PCB modification.

Frequently Asked Questions (FAQ)

Q: Can the TLVH431AILP be used as a direct replacement for the TLVH431ILPE3?

A: Yes. Both parts are shunt voltage reference ICs with identical output voltage range (1.24V to 18V), current ratings (70 mA output, 100 µA cathode), operating temperature (-40°C to 85°C), and TO-92-3 package configuration. The substitute offers improved tolerance (±1% versus ±1.5%).

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

A: No. Both parts use the TO-92-3 (TO-226AA) through-hole package with identical pinout and mechanical dimensions, enabling direct PCB substitution.

Q: What is the significance of the tolerance difference between ±1.5% and ±1%?

A: The TLVH431AILP provides tighter voltage regulation accuracy. Applications requiring higher precision voltage reference performance benefit from the improved tolerance specification.

Q: Why is the TLVH431ILPE3 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured. The TLVH431AILP (Last Time Buy status) represents the available alternative for continued design support and procurement.

Q: Are compliance certifications identical between the two parts?

A: Yes. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met in either configuration.
