Texas Instruments PT4584A Equivalent & Substitute Parts Reference

Part Overview

The PT4584A is a Texas Instruments Excalibur™ Series DC-DC converter module designed for ITE (Commercial) applications. It provides isolated power conversion from 18V to 60V DC input to a single 15V output at up to 2A (30W). This module's product status is Obsolete, making it necessary to find alternative models that strictly match electrical and mechanical parameters for direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PT4584A are determined by matching the following key parameters: input voltage range, output voltage and current, power rating, isolation voltage, application category, operating temperature range, mounting type, package/case, compliance (RoHS, REACH), and certification codes (ECCN, HTSUS). Substitute components listed meet or exceed the specifications in these fields and are provided only when product status allows direct replacement.

Parameter Comparison

Engineering Selection Recommendations

Due to the PT4584A’s obsolete product status, RP30-4815SFW from Recom Power is a viable substitute based on product status (active), RoHS3 compliance, REACH unaffected status, ECCN EAR99, and matching HTSUS codes. Both parts are certified to MSL 1 (unlimited) and meet the necessary operating temperature and application suitability requirements as specified.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters for substituting the PT4584A? A1: The primary substitution criteria are input voltage range, output voltage and current, power rating, isolation voltage, application category, operating temperature range, mounting type, and package/case.

Q2: Is the RP30-4815SFW compliant with relevant environmental and safety certifications required for direct replacement? A2: RP30-4815SFW is ROHS3 compliant, REACH unaffected, and holds identical ECCN and HTSUS certification codes as PT4584A. It is rated at MSL 1 (unlimited).

Q3: Does the substitute offer equivalent electrical performance at the operating temperature range specified? A3: Both PT4584A and RP30-4815SFW support an operating temperature range of -40°C to 85°C, ensuring directly comparable performance in the intended application category (ITE Commercial).

Q4: Are there any considerations regarding package differences when substituting? A4: PT4584A uses a 19-SIP module (3.00" x 1.19" x 0.50") while RP30-4815SFW uses a 6-DIP module (2.00" x 1.00" x 0.40"). Mechanical compatibility should be reviewed to align with existing board layouts and enclosures based strictly on the given package dimensions.

Q5: Are inventory levels significant for engineering substitution? A5: Both PT4584A and RP30-4815SFW have available inventory as specified, ensuring supply continuity for immediate replacement.
