Equivalent & Substitute Parts for PTH04T240FAS

Part Overview

The Texas Instruments PTH04T240FAS is a Non-Isolated PoL (Point of Load) DC/DC Converter designed for ITE (commercial) applications. It features a single output with a wide adjustable output voltage range (0.7V to 2V), an input voltage range of 2.2V to 5.5V, up to 10A output current, and advanced protection features such as Remote On/Off, Over Current Protection (OCP), Over Temperature Protection (OTP), and Under Voltage Lockout (UVLO). The module is ROHS3 compliant and available in a surface-mount 11-SMD package. The product is classified as obsolete, necessitating the identification of suitable alternatives for designs requiring active lifecycle and ongoing support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on equivalence in key functional, electrical, and compliance parameters within the DC/DC converter category. Allowed parameters for substitution include: module type (Non-Isolated PoL), number of outputs, input voltage range, output voltage range, maximum output current, applicable features, mounting style, compliance status (RoHS3 and REACH), and application domain. Substitution is further restricted to parts that match or closely align with these parameters.

Parameter Comparison

Engineering Selection Recommendations

The PTH04T240FAS is classified as obsolete, whereas the substitute part TPSM82866AA0HRDMR is listed as active and available with full support. Both parts are ROHS3 compliant, REACH unaffected, and fall under ECCN EAR99. Both parts are MSL 3 (168 Hours). Selection between these parts should be based on the current availability status, environmental compliance, and lifecycle classification as provided.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting DC/DC converters in the Non-Isolated PoL Module category?
A1: Substitution is based on matching module type, number of outputs, input voltage range, output voltage range, maximum output current, mounting style, application, and compliance status (RoHS, REACH, ECCN, MSL).

Q2: How does the input and output voltage range impact substitute suitability?
A2: Acceptable substitutes must operate within the same or compatible input and output voltage ranges specified for the application.

Q3: Is the package type a critical consideration when selecting a substitute?
A3: Yes, package type and mounting style affect mechanical fit and compatibility on the PCB; these should match or be compatible with the design requirements.

Q4: Are compliance and lifecycle status important in substitute selection?
A4: Yes, product status (active vs. obsolete), RoHS compliance, REACH status, and MSL classification are essential for qualification in regulated and long-life designs.

Q5: Can substitutes differ in maximum output current or efficiency?
A5: Substitutes must meet or exceed the necessary current requirements; efficiency may vary but should be reviewed relative to system specifications.
