PTH03050WAST DC DC Converter Equivalent & Substitute Parts

Part Overview

The PTH03050WAST is a non-isolated Point-of-Load (PoL) module DC DC converter manufactured by Texas Instruments. This surface-mount device delivers a single regulated output of 0.8 to 2.5V at 6A maximum current from a 2.95V to 3.65V input supply. The module is designed for commercial Information Technology Equipment (ITE) applications and includes integrated protection features including remote on/off control, output current protection (OCP), over-temperature protection (OTP), and under-voltage lockout (UVLO).

The PTH03050WAST is classified as an active product with full RoHS3 compliance and REACH unaffected status. Alternative part numbers within the same product family are available to accommodate different packaging and inventory requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the PTH03050WAST is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Must Match Exactly):

• Input voltage range: 2.95V to 3.65V
• Output voltage range: 0.8V to 2.5V
• Maximum output current: 6A
• Single output configuration
• Operating temperature range: -40°C to 85°C
• Efficiency: 94%

Mechanical Parameters (Must Match Exactly):

• Package type: 6-SMD Module
• Physical dimensions: 22.1mm × 12.7mm × 9.1mm
• Mounting type: Surface Mount

Compliance & Certification (Must Match Exactly):

• RoHS3 Compliant
• REACH Unaffected status
• Moisture Sensitivity Level 3

Functional Features (Must Match Exactly):

• Remote On/Off capability
• Output Current Protection (OCP)
• Over-Temperature Protection (OTP)
• Under-Voltage Lockout (UVLO)

The only allowable variation is in packaging format (Tape & Reel versus Tray), which does not affect electrical performance or mechanical compatibility on the PCB.

Parameter Comparison

Engineering Selection Recommendations

The PTH03050WAS is a direct electrical and mechanical equivalent to the PTH03050WAST. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and carry the same active product status with full RoHS3 compliance and REACH unaffected certification.

The sole difference between these parts is the packaging format: PTH03050WAST is supplied in Tape & Reel format, while PTH03050WAS is supplied in Tray format. This distinction affects only the delivery and handling method and does not impact PCB assembly compatibility, electrical performance, or thermal characteristics.

Selection between these two part numbers should be based on procurement requirements and assembly line equipment compatibility. Tape & Reel packaging is suitable for automated pick-and-place assembly systems, while Tray packaging is appropriate for manual assembly or alternative handling processes. Both formats maintain identical moisture sensitivity levels and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can PTH03050WAS be used as a direct replacement for PTH03050WAST on a PCB?

A: Yes. The PTH03050WAS is electrically and mechanically identical to the PTH03050WAST. Both parts have the same 6-SMD module footprint, identical pin configuration, and matching electrical specifications. The only difference is the packaging format (Tray versus Tape & Reel), which does not affect PCB assembly or performance.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel (TR) packaging supplies components wound on a continuous tape within a reel, optimized for automated assembly equipment. Tray packaging supplies components in a static-dissipative tray, suitable for manual assembly or alternative handling methods. Both formats contain the same component with identical specifications.

Q: Are there any electrical performance differences between PTH03050WAST and PTH03050WAS?

A: No. Both parts deliver identical electrical performance with 6A maximum output current, 0.8V to 2.5V output voltage range, 94% efficiency, and the same protection features (Remote On/Off, OCP, OTP, UVLO).

Q: Do both parts have the same compliance certifications?

A: Yes. Both PTH03050WAST and PTH03050WAS are RoHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 3, 168 hours).

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

A: Both parts operate across the same temperature range of -40°C to 85°C, suitable for commercial ITE applications.

Q: Can I mix PTH03050WAST and PTH03050WAS in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably in the same design and assembly process. The packaging format difference does not affect PCB compatibility or performance.

Q: What are the physical dimensions of these modules?

A: Both parts have identical dimensions of 22.1mm length × 12.7mm width × 9.1mm height in a 6-SMD module package format.

Q: Are there any input voltage or output current limitations I should be aware of?

A: Both parts operate with a 2.95V to 3.65V input range and deliver up to 6A maximum output current. Output voltage is adjustable from 0.8V to 2.5V. These specifications are identical for both part numbers.
