PTH03010WAS DC DC Converter Equivalent & Substitute Parts

Part Overview

The PTH03010WAS is a non-isolated Point-of-Load (PoL) module DC DC converter designed for commercial Information Technology Equipment (ITE) applications. This component delivers a single adjustable output voltage ranging from 0.8V to 2.5V at a maximum current of 15A, operating from a 2.95V to 3.65V input supply with 37W power capacity.

The original PTH03010WAS 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

Substitution eligibility for the PTH03010WAS is determined by strict alignment of electrical and mechanical parameters. The following criteria establish functional equivalence:

Electrical Compatibility Requirements:

• Input voltage range must match: 2.95V to 3.65V
• Output voltage range must match: 0.8V to 2.5V
• Maximum output current must equal or exceed: 15A
• Power rating must support: 37W minimum
• Single output configuration required
• Non-isolated PoL module topology required

Mechanical Compatibility Requirements:

• Surface mount mounting type
• 10-SMD module package type
• Physical dimensions compatible with 1.37" L × 0.62" W footprint

Functional Feature Requirements:

• Remote On/Off control capability
• Under-Voltage Lockout (UVLO) protection
• Operating temperature range: –40°C to +85°C minimum

The PTH03010WAS manufactured by Texas Instruments meets all established substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The Texas Instruments PTH03010WAS qualifies as a direct functional substitute for the obsolete ARTESYN PTH03010WAS based on complete electrical and mechanical parameter alignment.

Product Status Consideration: The Texas Instruments variant is classified as an active product with ongoing manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete ARTESYN original.

Compliance and Certification: The Texas Instruments PTH03010WAS achieves ROHS3 compliance, whereas the original ARTESYN part is non-compliant. This represents an improvement in environmental and regulatory alignment for new designs and production runs. The substitute also includes REACH Unaffected status, providing additional regulatory clarity.

Protection Feature Enhancement: The Texas Instruments version incorporates Over-Current Protection (OCP) and Over-Temperature Protection (OTP) in addition to the original Short-Circuit Protection (SCP) and UVLO features, providing enhanced system reliability.

Packaging and Handling: The substitute is supplied in tray packaging format. The Moisture Sensitivity Level increases from MSL 1 to MSL 3 (168 hours), requiring standard moisture control procedures during storage and handling consistent with industry practice for surface-mount components.

Physical Dimensions: Height dimension increases from 0.35" (8.9mm) to 0.38" (9.6mm), and width increases from 0.62" (15.7mm) to 0.62" (15.8mm). These minor dimensional variations remain within typical PCB layout tolerances for PoL module applications.

Frequently Asked Questions (FAQ)

Q: Can the Texas Instruments PTH03010WAS directly replace the ARTESYN PTH03010WAS in existing designs?

A: Yes. Both parts share identical electrical specifications: 2.95V–3.65V input, 0.8V–2.5V adjustable output, 15A maximum current, and 37W–38W power capacity. Both employ non-isolated PoL module topology in 10-SMD surface-mount packages with matching operating temperature ranges (–40°C to +85°C). The minor height and width dimensional increases (0.03" and 0.01" respectively) are within standard PCB layout tolerances.

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

A: The primary differences are: (1) Product Status—Texas Instruments is active while ARTESYN is obsolete; (2) RoHS Compliance—Texas Instruments achieves ROHS3 compliance versus non-compliance for ARTESYN; (3) Protection Features—Texas Instruments adds OCP and OTP protection; (4) Moisture Sensitivity—Texas Instruments is MSL 3 (168 hours) versus MSL 1 (unlimited) for ARTESYN; (5) Packaging—Texas Instruments is supplied in tray format.

Q: Are there any thermal or performance differences?

A: Both parts specify 93% efficiency and identical operating temperature ranges (–40°C to +85°C). The Texas Instruments variant includes additional thermal protection (OTP) not present in the original ARTESYN design.

Q: What is the impact of the increased Moisture Sensitivity Level?

A: The Texas Instruments part requires standard moisture control procedures during storage and handling, consistent with MSL 3 classification (168-hour floor life after moisture exposure). This is standard industry practice and does not impact performance or reliability when proper handling procedures are followed.

Q: Are there any supply chain advantages to using the Texas Instruments substitute?

A: Yes. The Texas Instruments PTH03010WAS is an active product with ongoing manufacturing support, ensuring consistent availability. The original ARTESYN part is obsolete and subject to supply constraints and potential discontinuation of remaining inventory.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The Texas Instruments PTH03010WAS achieves ROHS3 compliance and carries REACH Unaffected status, meeting current environmental and regulatory standards for commercial ITE applications.
