PTH04T231WAS Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments PTH04T231WAS is a non-isolated Point-of-Load (PoL) DC-DC converter module designed for ITE (Commercial) applications. It offers a single output voltage adjustable from 0.69V to 3.6V at up to 6A output current with remote on/off, OCP, OTP, and UVLO features. As this part is Obsolete, it is necessary to identify suitable substitute models with equivalent or compatible electrical and mechanical characteristics for continued production and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution is performed using only the provided electrical and mechanical parameters, certification status, and compliance data. Key parameters used in determining equivalency include type (Non-Isolated PoL Module), number of outputs, input voltage range, output voltage value and current, mounting type, RoHS/REACH status, and application suitability (ITE - Commercial). Only parts matching or exceeding critical performance characteristics, electrical ratings, and compliance requirements are included.

Parameter Comparison

Engineering Selection Recommendations

The PTH04T231WAS is classified as Obsolete, with ROHS3 and REACH compliance and an MSL rating of 3 (168 Hours). Substitute selection utilizes only parts with the same compliance status (ROHS3 Compliant, REACH Unaffected, MSL 3), same part category (Non-Isolated PoL Module), and matching application suitability (ITE - Commercial). All substitute options are additionally required to have an equivalent or narrower input voltage range within the same general classification per the provided parameters.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting a Non-Isolated PoL DC-DC converter?
A: The critical parameters are input voltage range, output voltage range and current, type, number of outputs, features, mounting type, and compliance information (RoHS/REACH/MSL).

Q: How does the package type affect substitutability?
A: Mechanical compatibility, including mounting style and package dimensions, must be verified based strictly on the listed package or case and mounting type.

Q: Are all substitute parts RoHS3 compliant and REACH unaffected?
A: Yes. Only parts with identical compliance status as the main part (ROHS3 Compliant and REACH Unaffected) are considered as valid substitutes.

Q: Are current rating and application relevant to part substitution?
A: Substitutes must match or exceed the specified current rating (6A) and must be intended for the same applications (ITE - Commercial).

Q: Does the substitute part TPSM82866AA0HRDMR support the same input voltage range?
A: TPSM82866AA0HRDMR supports a 2.4V - 5.5V input range, compared to the main part’s 2.2V - 5.5V input range.

Q: What about the output voltage range?
A: TPSM82866AA0HRDMR provides a fixed 1.2V output as opposed to the PTH04T231WAS which supports 0.69V to 3.6V. Only the provided values are considered when determining suitability.

Q: How is product status used in substitute selection?
A: Only parts with an 'Active' status are considered suitable substitutes for an 'Obsolete' part, ensuring supply continuity.
