Equivalent & Substitute Parts for PTH04T221WAS

Part Overview

The Texas Instruments PTH04T221WAS is a Non-Isolated PoL Module DC-DC Converter with a single output, capable of delivering 0.69 ~ 3.6V at up to 16A, accepting input voltages from 2.2V to 5.5V. The module features remote On/Off, Overcurrent Protection (OCP), Over Temperature Protection (OTP), and Under Voltage Lockout (UVLO), designed for ITE (Commercial) applications. Product status is obsolete, making it necessary to identify alternative or substitute models for continued design support and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on matching functional category, input voltage range, output voltage (number and range), output current, mounting type, and key compliance certifications. Parameters used for substitution include: non-isolated PoL module type, surface mount configuration, number of outputs, input and output voltage ratings, output current, operating temperature, and compliance (RoHS, REACH, MSL).

Parameter Comparison

Engineering Selection Recommendations

Selection priorities are determined by product status, regulatory compliance, and certifications. The main part, PTH04T221WAS, is obsolete, requiring migration to an active part. The substitute part TPSM82866AA0HRDMR is active, maintains ROHS3 compliance, MSL level, REACH status, ECCN, and HTSUS classification. These criteria are sufficient for inventory procurement and compliance requirements.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters in substituting Non-Isolated PoL Module DC DC Converters?
A: Key substitution parameters include input voltage range, output voltage rating, maximum output current, mounting type, number of outputs, and regulatory compliance (RoHS, REACH, ECCN, MSL).

Q: Does the substitute TPSM82866AA0HRDMR support the same mechanical mounting as PTH04T221WAS?
A: Both parts are designed for surface-mount applications. Specific footprint details are provided in the official part specifications.

Q: Are there any differences in environmental, safety, or compliance requirements between these parts?
A: Both parts are ROHS3 compliant, REACH unaffected, MSL 3 (168 Hours), and share ECCN and HTSUS classifications.

Q: Is the operating temperature range compatible?
A: The substitute part TPSM82866AA0HRDMR supports a wider temperature range (-40°C ~ 125°C) compared to the -40°C ~ 85°C range of PTH04T221WAS.

Q: How does part obsolescence impact long-term supply?
A: Obsolete status on the PTH04T221WAS requires migration to active parts such as TPSM82866AA0HRDMR to ensure uninterrupted supply chain and ongoing design support.

Q: Are packaging and moisture sensitivity specifications compatible?
A: Both parts have an MSL value of 3 (168 Hours), suitable for industry-standard storage and handling procedures.
