TLC7701QP Equivalent & Substitute Parts

Part Overview

The TLC7701QP is a power management integrated circuit (PMIC) functioning as a supervisor with push-pull, totem pole output configuration. Designed for single-channel voltage monitoring applications, this through-hole 8-DIP component provides active high/active low reset functionality with a 1.1ms minimum reset timeout. The device is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and support long-term product availability for applications requiring supervisor functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC7701QP is determined by the following critical parameters:

• Functional Category: Single-channel voltage supervisor with reset output
• Voltage Monitoring Capability: 1-channel configuration
• Output Type: Push-pull or open drain/open collector configurations are functionally compatible for reset signal generation
• Reset Logic Polarity: Active high/active low capability
• Operating Temperature Range: -40°C to 125°C compatibility
• Regulatory Compliance: ROHS3 and REACH compliance maintained
• Manufacturer Continuity: Texas Instruments as primary source

The TPS3760A012DYYR qualifies as a substitute based on equivalent single-channel voltage monitoring, compatible reset functionality, matching temperature range, and identical regulatory compliance. The transition from through-hole to surface-mount packaging and from push-pull to open drain output represents a design-level change requiring circuit board layout and signal conditioning evaluation.

Engineering Selection Recommendations

TLC7701QP (Primary Part)

• Recommended for existing designs with through-hole assembly processes and push-pull output requirements
• Last Time Buy status requires immediate action for long-term inventory planning
• ROHS3 and REACH compliant for regulated applications

TPS3760A012DYYR (Substitute Part)

• Recommended for new designs or redesigns incorporating surface-mount technology
• Active product status ensures long-term supply chain continuity
• ROHS3 and REACH compliant for regulated applications
• Requires circuit board layout modification and signal conditioning evaluation due to output type and timing differences
• Voltage threshold difference (0.8V vs. 1.1V) must be evaluated against application requirements
• Reset timeout specification (100µs maximum vs. 1.1ms minimum) represents a significant functional difference requiring application validation

Frequently Asked Questions (FAQ)

Q: Can TPS3760A012DYYR directly replace TLC7701QP in existing PCB designs? A: No. The TPS3760A012DYYR uses a different package (SOT-23-14 surface mount vs. 8-DIP through hole), different output configuration (open drain vs. push-pull), and different electrical specifications. PCB redesign and circuit adaptation are required.

Q: What are the key electrical differences between these parts? A: The primary differences are voltage threshold (1.1V vs. 0.8V), output type (push-pull totem pole vs. open drain), reset logic (active high/active low vs. active low only), and reset timeout (1.1ms minimum vs. 100µs maximum). These differences require application-level evaluation.

Q: Are both parts compliant with environmental and regulatory standards? A: Yes. Both TLC7701QP and TPS3760A012DYYR are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the TLC7701QP marked as Last Time Buy? A: Last Time Buy status indicates the manufacturer is discontinuing this product. Customers must plan inventory accordingly and evaluate substitute parts for future production needs.

Q: What mounting considerations apply to substitution? A: TLC7701QP uses through-hole mounting (8-DIP package), while TPS3760A012DYYR uses surface-mount technology (SOT-23-14). This requires different assembly processes, PCB footprints, and soldering methods.

Q: How do the reset timeout specifications affect substitution? A: TLC7701QP specifies 1.1ms minimum reset timeout, while TPS3760A012DYYR specifies 100µs maximum. This 10x difference in timing behavior requires validation against application power-on sequencing and system initialization requirements.
