TLV809I50DBVR Equivalent & Substitute Parts

Part Overview

The TLV809I50DBVR is an active low reset supervisor IC manufactured by Texas Instruments, designed for single-channel power supply monitoring in Surface Mount applications. This Power Management (PMIC) device operates across the industrial temperature range of -40°C to 85°C and is classified as Active product status with ROHS3 compliance. The TLV809I50DBVR is supplied in Cut Tape (CT) & Digi-Reel® packaging with 35,200 units currently in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when alternative packaging formats are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV809I50DBVR is determined by strict equivalence across the following critical parameters: voltage threshold (4.55V), output configuration (Push-Pull, Totem Pole), reset logic (Active Low), reset timeout (120ms minimum), operating temperature range (-40°C to 85°C), package type (SOT-23-3), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Parametric equivalents maintain identical electrical and mechanical specifications across all monitored parameters. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) and inventory availability. Parametric equivalents include TLV809I50DBVT, TLV809I50DBZR, and TLV809I50DBZT, all manufactured by Texas Instruments under the TLV809 base product series.

Cross-manufacturer substitutes from the TPS3809 series (TPS3809I50DBVR and TPS3809I50DBVT) maintain identical functional parameters and are also manufactured by Texas Instruments, differing only in base product designation while preserving all electrical characteristics and compliance status.

The manufacturer-recommended substitute APX809S-46SA-7 from Diodes Incorporated represents a functional alternative with allowable parameter variations: voltage threshold of 4.63V (versus 4.55V), reset timeout of 140ms minimum (versus 120ms minimum), and extended operating temperature range of -40°C to 125°C (versus -40°C to 85°C). These variations remain within acceptable substitution tolerances for single-channel supervisor applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued regulatory support and manufacturing availability. Texas Instruments parametric equivalents (TLV809I50DBVT, TLV809I50DBZR, TLV809I50DBZT, TPS3809I50DBVR, TPS3809I50DBVT) are direct functional replacements with identical electrical specifications and are recommended for applications requiring strict parameter matching.

Selection between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging formats depends on assembly process requirements and volume handling procedures. TLV809I50DBZR offers the highest inventory availability (73,850 units) among parametric equivalents in Cut Tape format.

The APX809S-46SA-7 from Diodes Incorporated is suitable for applications where the extended operating temperature range (-40°C to 125°C) provides design margin or where slightly higher voltage threshold (4.63V) and reset timeout (140ms) are acceptable. This part is classified as manufacturer-recommended and maintains equivalent compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can TLV809I50DBVT be used as a direct replacement for TLV809I50DBVR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (4.55V threshold, 120ms reset timeout, -40°C to 85°C operating range). The only difference is packaging format: TLV809I50DBVR uses Cut Tape (CT) & Digi-Reel® while TLV809I50DBVT uses Tape & Reel (TR). Selection depends on assembly equipment compatibility.

Q: What is the difference between TLV809 and TPS3809 series parts?

A: Both series are manufactured by Texas Instruments and maintain identical functional parameters for the I50 threshold variant. The base product designation differs, but electrical characteristics, compliance status, and performance specifications are equivalent. Both are suitable for direct substitution.

Q: Is APX809S-46SA-7 a direct replacement?

A: APX809S-46SA-7 is a functional alternative with allowable parameter variations. The voltage threshold is 4.63V (0.08V higher), reset timeout is 140ms minimum (20ms longer), and operating temperature extends to 125°C (40°C higher). These variations are acceptable for most single-channel supervisor applications but should be verified against specific circuit requirements.

Q: What packaging format should I select?

A: Cut Tape (CT) & Digi-Reel® packaging is suitable for lower-volume or manual assembly processes. Tape & Reel (TR) packaging is optimized for high-speed automated assembly equipment. Both formats contain identical components; selection depends on manufacturing process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the manufacturer-recommended APX809S-46SA-7, maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance across all substitution options.
