TPS40061PWPR Equivalent & Substitute Parts

Part Overview

The TPS40061PWPR is an active buck regulator controller IC manufactured by Texas Instruments, designed for step-down DC-DC conversion applications. This device functions as a positive output transistor driver with integrated control features including current limiting, enable control, frequency adjustment, and soft start capability. The part is currently in active production status with 2600 units available in new original inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS40061PWPR is determined by strict equivalence across the following critical parameters:

• Topology & Function: Buck regulator controller with step-down positive output configuration
• Electrical Performance: Supply voltage range 10V ~ 55V, switching frequency up to 1MHz, 98% maximum duty cycle
• Control Architecture: Transistor driver output with current limit, enable, frequency control, and soft start features
• Synchronization Capability: Integrated clock sync and synchronous rectifier support
• Package Compatibility: 16-PowerTSSOP (16-HTSSOP) surface mount package with identical pinout and thermal characteristics
• Compliance & Status: Active product status, ROHS3 compliant, REACH unaffected, MSL 2 rating

The TPS40060PWPR meets all substitution criteria as a parametric equivalent within the same product family.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS40061PWPR and TPS40060PWPR are active production devices from Texas Instruments with identical electrical specifications and package compatibility. Selection between these parts should be based on:

• Packaging Format Requirements: The TPS40061PWPR is supplied in Tape & Reel (TR) format, while the TPS40060PWPR is available in Cut Tape (CT) and Digi-Reel® formats. Choose based on assembly line requirements and quantity needs.
• Inventory Availability: The TPS40060PWPR has higher stock availability (4371 units) compared to the TPS40061PWPR (2600 units), which may influence lead time considerations.
• Regulatory Compliance: Both parts meet ROHS3 compliance and REACH unaffected status, suitable for applications requiring environmental regulation adherence.
• Moisture Handling: Both parts carry MSL 2 rating with 1-year floor life, requiring standard moisture control during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the TPS40060PWPR directly replace the TPS40061PWPR in existing designs?

A: Yes. Both devices are parametric equivalents with identical electrical specifications, control features, and 16-HTSSOP package pinout. Direct substitution is supported without circuit modification.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (Tape & Reel versus Cut Tape/Digi-Reel) and current inventory levels. Electrical performance and package dimensions are identical.

Q: Are there any compatibility concerns with PCB assembly equipment?

A: No. Both parts use the same 16-PowerTSSOP surface mount package with 0.173" width and 4.40mm dimensions, compatible with standard pick-and-place equipment.

Q: Do both parts support the same control features?

A: Yes. Both the TPS40061PWPR and TPS40060PWPR include current limit, enable, frequency control, and soft start functionality with identical operating characteristics.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 85°C (TA), suitable for industrial and commercial temperature environments.

Q: Are there supply voltage limitations?

A: Both parts accept supply voltage from 10V to 55V (Vcc/Vdd), with maximum duty cycle of 98% and switching frequency up to 1MHz.

Q: Which part should I select for new designs?

A: Selection should be based on packaging format preference and availability. Both parts are active production devices with equivalent performance and compliance status.
