Equivalent & Substitute Parts for AXA003A0X4Z

Part Overview

The OmniOn Power AXA003A0X4Z is a Non-Isolated PoL Module DC DC Converter designed for ITE (Commercial) applications. This component features a single output voltage range of 0.8V to 5.5V with an output current of 3A, and operates from an input voltage of 8.3V to 14V. The device offers features such as Remote On/Off, OCP, OTP, and UVLO, and is provided in a 5-SIP Through Hole package. As the AXA003A0X4Z is now classified as obsolete, it is necessary to identify direct alternative models that fulfill equivalent electrical and mechanical requirements for design continuity.

Substitute Part Grouping Explanation

Substitution is based strictly on the following allowed parameters for this category: type (Non-Isolated PoL Module), single output configuration, input voltage range compatibility, output voltage range, maximum output current, required features (Remote On/Off, OCP, OTP, UVLO), operating temperature range, and mounting/package compatibility. Only parts meeting these criteria and explicitly listed as substitutes are considered equivalent.

Engineering Selection Recommendations

AXA003A0X4Z is obsolete. Substitute part PJT004A0X3-SRZ is active and RoHS compliant. Both parts belong to the Non-Isolated PoL Module product category and comply with ECCN EAR99 and HTSUS 8504.40.9580 classifications. Selection should align with available inventory and required compliance status as provided.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters for selecting a substitute for AXA003A0X4Z?
A1: Critical parameters include Non-Isolated PoL Module type, number of outputs, compatible input and output voltage ranges, maximum output current, required features such as Remote On/Off, OCP, OTP, UVLO, operating temperature range, and package/mounting type.

Q2: Are the substitute and original parts functionally equivalent?
A2: Both AXA003A0X4Z and PJT004A0X3-SRZ are Non-Isolated PoL Modules with similar voltage and current specifications, and both provide Remote On/Off, OCP, OTP, and UVLO features with -40°C to 85°C operating temperature range.

Q3: Does the package or mounting type differ between AXA003A0X4Z and PJT004A0X3-SRZ?
A3: Yes. AXA003A0X4Z uses a 5-SIP Through Hole package, while PJT004A0X3-SRZ uses a 17-SMD Surface Mount package. This difference should be accounted for in board design.

Q4: How does the efficiency compare between the main and substitute parts?
A4: AXA003A0X4Z has 91% efficiency, while PJT004A0X3-SRZ provides 94.6% efficiency.

Q5: Is RoHS compliance a factor in substitution?
A5: PJT004A0X3-SRZ is listed as RoHS compliant. AXA003A0X4Z does not explicitly state RoHS compliance in the provided parameters. Users should verify compliance requirements as indicated.
