PT4223C Equivalent & Substitute Parts Reference

Part Overview

The PT4223C from Texas Instruments is an obsolete isolated DC-DC converter module designed for ITE (Commercial) applications. It provides a regulated 5V output at up to 2A with input voltage range from 36V to 75V and incorporates features such as remote On/Off, overcurrent protection (OCP), short-circuit protection (SCP), and undervoltage lockout (UVLO). Due to its obsolete status, it is necessary to identify alternative models that match the critical electrical, mechanical, and compliance requirements for continued system compatibility and design support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Texas Instruments PT4223C are chosen strictly based on matching the following key electrical and mechanical parameters: input voltage range, output voltage, output current, power rating, number of outputs, isolation voltage, mounting type, compliance status (RoHS and REACH), and application (ITE Commercial). Substitute parts must also provide required features such as remote On/Off, OCP, and SCP to ensure functional equivalence within intended use cases.

Engineering Selection Recommendations

Selection of substitute parts for the PT4223C should prioritize product status and regulatory compliance. The PT4223C is obsolete, while the recommended substitute, REC10-4805SRW/H2/A/M/SMD from Recom Power, is an active product and maintains necessary RoHS3 and REACH compliance, with a matching ECCN and HTSUS classification. Substitute selection should always reference the provided certifications and status to ensure continued conformity with regulatory requirements.

Frequently Asked Questions (FAQ)

Q1: What are the mandatory criteria for substituting PT4223C in ITE (Commercial) applications?
A1: Substitution requires matching input voltage range, output voltage, output current, power rating, isolation voltage, number of outputs, mounting type, features, and compliance parameters.

Q2: Is the REC10-4805SRW/H2/A/M/SMD directly compatible with systems designed for PT4223C?
A2: REC10-4805SRW/H2/A/M/SMD matches the main electrical and mechanical parameters, including voltage, output, type, and compliance-related characteristics defined for PT4223C.

Q3: Does the package differ between PT4223C and REC10-4805SRW/H2/A/M/SMD?
A3: PT4223C uses a 10-SMD module package, while REC10-4805SRW/H2/A/M/SMD uses a 24-SMD module, 18 leads. Dimensional and pinout verification based on provided mechanical parameters is necessary within the constraints of matching only listed features.

Q4: What compliance standards are met by both PT4223C and REC10-4805SRW/H2/A/M/SMD?
A4: Both products are ROHS3 compliant and unaffected by REACH. They also share similar ECCN (EAR99) and HTSUS codes.

Q5: How should thermal and efficiency differences be considered when selecting alternatives?
A5: Only provided operating temperature and efficiency parameters may be compared: PT4223C operates at up to 85°C with 85% efficiency, while REC10-4805SRW/H2/A/M/SMD operates up to 75°C with 87% efficiency. Use only these provided attributes for selection – do not extrapolate or infer suitability beyond supplied values.
