Substitute Part Grouping Explanation

Substitute parts for the TLV809K33DBVT are grouped based on strict parametric equivalence. All identified substitutes maintain the following critical parameters:

Single-channel voltage monitoring with 2.93V threshold
Push-pull, totem pole output configuration
Active low reset logic with 120ms minimum timeout
SOT-23-3 surface mount package
ROHS3 compliance and unlimited MSL rating
Operating temperature range of -40°C to 85°C

Substitutes are differentiated by packaging format (Tape & Reel versus Cut Tape & Digi-Reel), product status (Active versus Obsolete), and base product series designation. All Texas Instruments TLV809 and TPS3809 variants listed maintain full parametric compatibility. The Diodes Incorporated APX809S-29SA-7 is included as a manufacturer-recommended alternative with extended operating temperature range and slightly longer reset timeout.

Engineering Selection Recommendations

All Texas Instruments TLV809 and TPS3809 series parts listed maintain full parametric equivalence with the TLV809K33DBVT and are suitable for direct substitution in active designs. These parts are in active product status with ROHS3 compliance and unlimited MSL rating.

The TPS3809K33DBVRG4 is available in inventory but carries obsolete product status and should be avoided for new designs or long-term supply chain planning.

The APX809S-29SA-7 from Diodes Incorporated is a manufacturer-recommended alternative that provides extended operating temperature range (-40°C to 125°C) and slightly longer reset timeout (140ms minimum). This part is suitable for applications requiring higher temperature operation while maintaining all other functional parameters.

Packaging format selection (Tape & Reel versus Cut Tape & Digi-Reel) depends on procurement and assembly requirements and does not affect electrical or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute TLV809K33DBVT with TPS3809K33DBVT?

A: Yes. Both parts share identical electrical parameters including 2.93V threshold voltage, 120ms reset timeout, push-pull totem pole output, and SOT-23-3 package. The primary difference is packaging format. TPS3809K33DBVT is supplied in Cut Tape & Digi-Reel format while TLV809K33DBVT is supplied in Tape & Reel format.

Q: What is the difference between TLV809K33DBVR and TLV809K33DBZR?

A: Both parts are electrically identical with matching threshold voltage, reset timeout, and output configuration. The difference is in the packaging format: TLV809K33DBVR is supplied in Cut Tape & Digi-Reel format, while TLV809K33DBZR is supplied in Tape & Reel format.

Q: Is APX809S-29SA-7 a direct replacement for TLV809K33DBVT?

A: APX809S-29SA-7 is functionally compatible with matching voltage threshold, output type, and package. However, it differs in two parameters: extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) and longer reset timeout (140ms minimum versus 120ms minimum). These differences make it suitable for applications requiring higher temperature operation.

Q: Should I use TPS3809K33DBVRG4 for new designs?

A: No. TPS3809K33DBVRG4 is in obsolete product status. For new designs, select from active status parts such as TLV809K33DBVT, TLV809K33DBVR, TPS3809K33DBVT, or TPS3809K33DBVR.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance profile of the TLV809K33DBVT.

Q: What packaging format should I select?

A: Packaging format selection depends on your procurement and assembly process. Tape & Reel (TR) format is standard for high-volume automated assembly. Cut Tape (CT) & Digi-Reel format is suitable for lower-volume or mixed-component orders. Electrical and functional performance is identical regardless of packaging format.
