TPS3514D Equivalent & Substitute Parts

Part Overview

The TPS3514D is a multi-voltage supervisor IC manufactured by Texas Instruments, designed for power management applications requiring monitoring of three independent voltage rails. This device features open drain or open collector output configuration with active low reset functionality and a 200ms minimum reset timeout. The TPS3514D is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is essential for design continuity, long-term supply chain planning, and ensuring system reliability in applications where the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS3514D is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of voltages monitored (3 channels required)
• Voltage threshold values (3.3V, 5V, 12V compatibility)
• Output configuration (Open Drain or Open Collector)
• Reset logic polarity (Active Low)
• Reset timeout specification (200ms minimum)
• Package compatibility (14-SOIC form factor)
• Operating temperature range (-40°C ~ 85°C minimum)

Substitute Categories:

Parametric Equivalent: TPS3513D matches all critical electrical and mechanical parameters of the TPS3514D, including 3-channel voltage monitoring, identical threshold values, output configuration, reset characteristics, and 14-SOIC packaging. This part provides direct functional equivalence with identical performance specifications.

Functional Alternative: TPS3808G01DBVR is a single-channel supervisor with adjustable/selectable voltage thresholds and reset timeout. While this part shares the same output configuration (Open Drain or Open Collector), active low reset logic, and RoHS3 compliance, it differs fundamentally in channel count (1 vs. 3) and threshold flexibility. This part is suitable only for applications where single-channel monitoring is acceptable or where adjustable thresholds provide design advantages.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent):

The TPS3513D is the recommended substitute for the TPS3514D in applications requiring identical electrical and mechanical specifications. Both parts are Last Time Buy status devices with equivalent performance characteristics. The TPS3513D maintains the same 3-channel voltage monitoring architecture, fixed threshold values (3.3V, 5V, 12V), and 14-SOIC packaging. Current inventory availability of 3550 units supports near-term procurement requirements. Both parts meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

For Functional Alternative (Single-Channel Applications):

The TPS3808G01DBVR is suitable only for applications where single-channel voltage monitoring is sufficient. This part offers extended operating temperature range (-40°C ~ 125°C) and adjustable/selectable voltage thresholds and reset timeout, providing design flexibility not available in the fixed-threshold TPS3514D. However, the SOT-23-6 package requires PCB layout modification, and the single-channel architecture eliminates multi-rail monitoring capability. This part is Active status with significantly higher inventory availability (120310 units), supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the TPS3513D be used as a direct replacement for the TPS3514D?

A: Yes. The TPS3513D is a parametric equivalent with identical electrical specifications, including 3-channel voltage monitoring, fixed thresholds (3.3V, 5V, 12V), open drain/open collector output, active low reset, 200ms reset timeout, and 14-SOIC packaging. No circuit modifications are required.

Q: What are the key differences between the TPS3514D and TPS3808G01DBVR?

A: The TPS3808G01DBVR is a single-channel supervisor with adjustable thresholds and reset timeout, compared to the TPS3514D's fixed 3-channel architecture. The TPS3808G01DBVR uses SOT-23-6 packaging instead of 14-SOIC and supports extended temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C). This part is suitable only for applications requiring single-channel monitoring.

Q: Why is the TPS3514D classified as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued or is discontinuing production. This classification necessitates identifying equivalent parts for future designs and supply chain planning. The TPS3513D provides parametric equivalence for continued availability.

Q: Are package changes required when substituting the TPS3514D?

A: The TPS3513D uses identical 14-SOIC packaging, requiring no PCB modifications. The TPS3808G01DBVR uses SOT-23-6 packaging, which requires PCB layout changes and is suitable only for single-channel applications.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. The TPS3513D and TPS3808G01DBVR are both ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited) moisture sensitivity rating, matching the TPS3514D compliance profile.

Q: What is the inventory status for substitute parts?

A: TPS3513D has 3550 units in stock (Last Time Buy status). TPS3808G01DBVR has 120310 units in stock (Active status), providing superior long-term availability for new designs.
