Equivalent & Substitute Parts Reference: PTH05030WAS

Part Overview

The Texas Instruments PTH05030WAS is an obsolete non-isolated Point-of-Load (PoL) DC-DC converter module. It provides a single adjustable output from 0.8V to 3.6V, delivering up to 30A output current from a 4.5V to 5.5V input. Due to its obsolete status, sourcing suitable substitute parts is essential for ongoing support and designs requiring maintenance or redesign. Replacement parts must match critical electrical, mechanical, and compliance parameters to ensure functional compatibility.

Engineering Selection Recommendations

The PTH05030WAS is obsolete, and its replacement must align with available inventory, compliance requirements (RoHS3, REACH, ECCN EAR99), and matching regulatory codes. The TPSM82866AA0HRDMR from Texas Instruments meets these compliance and regulatory criteria as provided in the supplied information.

Frequently Asked Questions (FAQ)

Q1: What determines whether the TPSM82866AA0HRDMR is a suitable substitute for the PTH05030WAS?
A1: Suitability is determined strictly by consistent input voltage range, output configuration, mounting type, features, regulatory compliance (RoHS3, REACH), and relevant HTSUS/ECCN codes provided in the documentation.

Q2: Are there differences in package or mounting methods between the original and substitute parts?
A2: The PTH05030WAS uses a 13-SMD Module, whereas the TPSM82866AA0HRDMR uses a 23-PowerLFQFN Module, both intended for surface mount assembly. Only these details are considered, as provided.

Q3: What are the main functional differences based on the provided parameters?
A3: The PTH05030WAS delivers up to 30A at an adjustable output voltage (0.8–3.6V), while the TPSM82866AA0HRDMR provides 6A at 1.2V. Input voltage overlap is present as per provided specifications.

Q4: Are regulatory and environmental compliance aspects consistent across the suggested substitute?
A4: Both devices are ROHS3 Compliant and REACH Unaffected, sharing ECCN EAR99 and HTSUS 8504.40.9580 codes.

Q5: Do both devices support similar application usage?
A5: Both are non-isolated PoL DC-DC converter modules intended for ITE (Commercial) applications as specified.
