PT4502N Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments PT4502N is a DC-DC isolated converter module delivering a single 5V output at up to 4A from an 18V–40V input range, rated at 20W. It features a 1.5 kV isolation rating and integrated UVLO (Under Voltage Lock Out) protection. The PT4502N is classified as obsolete, necessitating the identification and use of equivalent or substitute DC-DC converter parts to ensure continued system operation and design support where the original module is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of DC-DC converter modules is determined solely by matching primary electrical, mechanical, and compliance parameters as outlined in the input. The following parameters are strictly used to justify substitute groupings: input voltage range, output voltage, output current, output power, isolation voltage, mounting type, number of outputs, application class, temperature range, and relevant compliance statuses. Only modules precisely matching or exceeding these specifications are grouped as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of the RP20-4805SFW as a substitute for the PT4502N follows from matching key product status (active), RoHS3 compliance, REACH unaffected status, and MSL grade. The substitute module meets or exceeds the relevant compliance standards and critical inventory availability requirements. Selection does not introduce any additional evaluation criteria.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for the PT4502N to be substituted?
A1: Input voltage range, output voltage, output current, output power rating, isolation voltage, number of outputs, compliance certifications (RoHS, REACH), operating temperature, and mounting type.

Q2: Is the package or mounting method compatible between PT4502N and RP20-4805SFW?
A2: Both PT4502N and RP20-4805SFW utilize through-hole mounting; package styles differ but fall within the same general module implementation category.

Q3: What product statuses must be considered when selecting a substitute?
A3: The substitute should have an active product status when replacing an obsolete product to ensure continuity of supply.

Q4: How do compliance standards affect substitution?
A4: Substitute parts must meet or exceed the RoHS3 and REACH compliance required by the original module.

Q5: Does the operating temperature range need to match exactly?
A5: Operating temperature must fall within or cover all application-specific requirements as dictated by the module specifications provided.

Q6: Does efficiency affect substitution?
A6: Efficiency is a critical parameter and must be compared directly; both modules meet or exceed each other’s efficiency levels as stated in their specifications.
