TLV810SDBZR Equivalent & Substitute Parts

Part Overview

The TLV810SDBZR is a single-channel power management supervisor IC manufactured by Texas Instruments, designed for reset and power-on reset applications. This component operates as a push-pull, totem pole output supervisor with a 2.93V voltage threshold and 120ms minimum reset timeout. The device is packaged in SOT-23-3 surface mount configuration.

The TLV810SDBZR carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV810SDBZR are qualified based on the following critical parameters that determine functional compatibility:

• Voltage Threshold: 2.93V (all substitutes match this specification)
• Output Configuration: Push-Pull, Totem Pole (all substitutes maintain this output type)
• Reset Logic: Active High (all substitutes maintain this reset behavior)
• Number of Voltages Monitored: 1 Channel (all substitutes are single-channel devices)
• Package / Case: SOT-23-3 (all substitutes use identical physical packaging)
• Mounting Type: Surface Mount (all substitutes are surface mount compatible)
• Operating Temperature Range: -40°C ~ 125°C (all substitutes support this range)
• Compliance: ROHS3 Compliant, MSL 1, REACH Unaffected (all substitutes meet these requirements)

Reset timeout specifications vary among substitutes (120ms, 130ms, 140ms minimum), which represents the primary parametric difference. All substitutes maintain electrical and mechanical compatibility with the original TLV810SDBZR design.

Parameter Comparison

Engineering Selection Recommendations

TLV810EA29DBZR (Texas Instruments, Active Status)

This part is the manufacturer-recommended substitute for the obsolete TLV810SDBZR. It maintains identical electrical specifications with a 130ms minimum reset timeout, representing a 10ms increase from the original. Active product status ensures long-term availability and ongoing manufacturer support. This part is suitable for new designs and production continuity applications.

TLV810SDBZT (Texas Instruments, Obsolete Status)

This parametric equivalent maintains the original 120ms reset timeout specification and identical electrical characteristics. However, it carries Obsolete product status, limiting its suitability for long-term supply chain planning. This part may be considered only when reset timeout precision at 120ms is a critical design requirement and TLV810EA29DBZR's 130ms specification is incompatible.

APX810S-29SA-7 (Diodes Incorporated, Active Status)

This cross-manufacturer substitute from Diodes Incorporated provides Active product status with identical electrical and mechanical compatibility. The 140ms minimum reset timeout represents a 20ms increase from the original specification. This part is suitable for applications where the extended reset timeout does not impact system performance and offers an alternative supply source from a different manufacturer.

Frequently Asked Questions (FAQ)

Q: Can TLV810EA29DBZR directly replace TLV810SDBZR in existing designs?

A: Yes. TLV810EA29DBZR maintains identical voltage threshold (2.93V), output configuration (push-pull, totem pole), reset logic (active high), and package (SOT-23-3). The reset timeout increases from 120ms to 130ms minimum. Designs must tolerate this 10ms increase in reset delay.

Q: What is the primary difference between the substitute parts?

A: The reset timeout specification varies: TLV810SDBZR and TLV810SDBZT specify 120ms minimum, TLV810EA29DBZR specifies 130ms minimum, and APX810S-29SA-7 specifies 140ms minimum. All other electrical and mechanical parameters remain identical.

Q: Are all substitute parts available in the same package?

A: Yes. All parts use SOT-23-3 surface mount packaging (TO-236-3, SC-59 designations). Pin configuration and PCB footprint compatibility is maintained across all substitutes.

Q: Which substitute should be selected for new production?

A: TLV810EA29DBZR is recommended for new production due to its Active product status and manufacturer recommendation. APX810S-29SA-7 provides an alternative from Diodes Incorporated with equivalent functionality and Active status.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All parts are ROHS3 Compliant, carry MSL 1 (Unlimited), and are REACH Unaffected. Compliance certifications are identical across all substitutes.

Q: Can APX810S-29SA-7 be used interchangeably with Texas Instruments parts?

A: Yes, from an electrical and mechanical standpoint. APX810S-29SA-7 maintains identical voltage threshold, output configuration, reset logic, and package specifications. The 140ms reset timeout must be evaluated for system compatibility.
