Equivalent & Substitute Parts Reference: PTH05010YAST

Part Overview

The Texas Instruments PTH05010YAST is a DC-DC converter designed as a Non-Isolated PoL Module, providing 1 output voltage adjustable from 0.55V to 1.8V with a maximum output current of 15A. The accepted input voltage range is 4.5V to 5.5V. Key features include Remote On/Off, Over-Current Protection (OCP), and Under-Voltage Lockout (UVLO). The component is supplied in a surface mount, 10-SMD module package, making it suitable for commercial ITE applications. With the product status marked as Obsolete, engineers must identify substitute models to maintain design support and supply continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based strictly on provided electrical and mechanical parameters. The allowed parameters for substitution include: input voltage range, output voltage range, maximum output current, number of outputs, features set, series, mounting type, package/case type, size/dimensions, operating temperature range, and regulatory compliance (RoHS, REACH, MSL). All listed substitute parts must match these parameters to qualify as direct replacements.

Parameter Comparison

Engineering Selection Recommendations

The PTH05010YAST part is marked as Obsolete and RoHS non-compliant, while the PTH05010YAZ is Active and ROHS3 Compliant. Both parts feature identical electrical and mechanical parameters and adhere to REACH Unaffected status. Engineers should select substitute parts with comparable performance, compliance levels, and regulatory certifications based on application requirements and supply continuity.

Frequently Asked Questions (FAQ)

Q1: What are the key substitution criteria for DC-DC converter modules like PTH05010YAST?
A1: The key substitution criteria include input voltage range, output voltage range, output current rating, number of outputs, features, package type, mounting type, size/dimensions, operating temperature, and regulatory compliance parameters.

Q2: Is PTH05010YAZ a direct substitute for PTH05010YAST based on provided parameters?
A2: Yes. PTH05010YAZ matches all electrical, mechanical, and compliance parameters outlined for PTH05010YAST.

Q3: What package type and mounting considerations must be matched?
A3: Both parts use a 10-SMD Module package and are designed for surface mount installation. Mechanical compatibility is maintained.

Q4: How does RoHS and MSL status affect substitute selection?
A4: RoHS compliance may be required for certain regulatory environments. PTH05010YAZ is ROHS3 Compliant with MSL 3, while PTH05010YAST is RoHS non-compliant with MSL 1. Selection depends on compliance requirements for the intended application.

Q5: When should an engineer review product status and inventory information in substitution?
A5: Product status (Obsolete vs. Active), alongside current inventory levels, should be considered to ensure continuous supply and adherence to lifecycle requirements.
