PTH05060WAS DC DC Converter Equivalent & Substitute Parts

Part Overview

The PTH05060WAS is a non-isolated Point-of-Load (PoL) module DC DC converter designed for commercial Information Technology Equipment (ITE) applications. This component delivers 36W of power with a single adjustable output ranging from 0.8V to 3.6V at 10A maximum current, operating from a 4.5V to 5.5V input supply.

The original PTH05060WAS manufactured by ARTESYN / Advanced Energy is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this converter topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PTH05060WAS are identified based on strict electrical and mechanical parameter matching within the non-isolated PoL module category. The substitution criteria are:

Electrical Parameters (Critical):

• Input voltage range: 4.5V – 5.5V
• Output voltage range: 0.8V – 3.6V
• Maximum output current: 10A
• Power rating: 36W
• Single output configuration
• Operating temperature range: –40°C to +85°C
• Efficiency: 94%

Mechanical Parameters (Critical):

• Mounting type: Surface Mount
• Package type: 10-SMD Module
• Form factor compatibility within specified dimensions

Functional Features:

• Remote On/Off capability
• Under-Voltage Lockout (UVLO) protection
• Short-Circuit Protection (SCP) or Over-Current Protection (OCP)

Parts meeting all electrical and mechanical parameters are classified as direct substitutes. Variations in protection features, product status, compliance certifications, and packaging configurations are noted but do not disqualify substitution eligibility when core electrical specifications align.

Parameter Comparison

Engineering Selection Recommendations

The Texas Instruments PTH05060WAS represents a direct electrical and mechanical substitute for the obsolete ARTESYN PTH05060WAS. Both components share identical electrical specifications across input voltage, output voltage range, current capacity, power rating, and operating temperature range.

Product Status Consideration: The Texas Instruments variant is classified as Active, providing assured long-term availability and continued manufacturer support. The ARTESYN original is Obsolete, making the Texas Instruments substitute the appropriate selection for new designs and ongoing production.

Compliance and Certifications: The Texas Instruments version includes ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for commercial ITE applications. Both variants carry identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications.

Protection Features: The Texas Instruments variant includes Over-Temperature Protection (OTP) in addition to the Over-Current Protection (OCP) present in the ARTESYN design, providing enhanced thermal management. Both retain Remote On/Off and UVLO functionality.

Packaging and Handling: The Texas Instruments part is supplied in Tray packaging with MSL 3 (168 Hours) moisture sensitivity, compared to the ARTESYN MSL 1 (Unlimited). Standard moisture control procedures during storage and assembly are required for the Texas Instruments variant.

Dimensional Compatibility: Physical dimensions are equivalent within manufacturing tolerance (ARTESYN: 25.4mm × 15.7mm × 8.9mm; Texas Instruments: 25.3mm × 15.8mm × 9.6mm), ensuring PCB layout and thermal management compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Texas Instruments PTH05060WAS directly replace the ARTESYN PTH05060WAS in existing designs?

A: Yes. Both components meet identical electrical specifications for input voltage (4.5V–5.5V), output voltage range (0.8V–3.6V), maximum output current (10A), power rating (36W), and operating temperature range (–40°C to +85°C). Physical dimensions are equivalent within manufacturing tolerance, and both use 10-SMD Module surface mount packaging. The Texas Instruments variant is the appropriate selection due to its Active product status.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product Status—ARTESYN is Obsolete while Texas Instruments is Active; (2) Protection Features—Texas Instruments includes Over-Temperature Protection (OTP) in addition to Over-Current Protection (OCP); (3) Compliance—Texas Instruments includes ROHS3 and REACH certifications; (4) Moisture Sensitivity—ARTESYN is MSL 1 (Unlimited) while Texas Instruments is MSL 3 (168 Hours); (5) Packaging—ARTESYN is supplied in bulk while Texas Instruments is supplied in Tray format.

Q: Are there any thermal or reliability concerns when switching from ARTESYN to Texas Instruments?

A: Both components operate at 94% efficiency and share identical thermal operating ranges (–40°C to +85°C). The Texas Instruments variant includes additional Over-Temperature Protection, which enhances thermal management. Dimensional differences are minimal (less than 1mm in height) and do not affect thermal performance or PCB layout compatibility.

Q: What moisture handling procedures apply to the Texas Instruments variant?

A: The Texas Instruments PTH05060WAS carries MSL 3 (168 Hours) moisture sensitivity. Components must be stored in dry conditions and used within 168 hours of package opening. Standard moisture control procedures, including desiccant storage and baking if necessary, apply per IPC-A-610 guidelines.

Q: Are both parts suitable for ITE (Commercial) applications?

A: Yes. Both the ARTESYN and Texas Instruments PTH05060WAS are specified for ITE (Commercial) applications. The Texas Instruments variant includes ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for commercial equipment.

Q: What is the significance of the part number PTH05060W (36W) series designation?

A: The PTH05060W series designation indicates the 36W power class and non-isolated PoL module topology. Both the ARTESYN and Texas Instruments variants belong to this series, confirming functional equivalence and design compatibility.

Q: Can the output voltage be adjusted on both variants?

A: Yes. Both components provide adjustable output voltage from 0.8V to 3.6V, enabling configuration for specific load requirements within this range. Remote On/Off control is available on both variants.
