Equivalent & Substitute Parts Reference for PT6409P

Part Overview

Texas Instruments PT6409P is a non-isolated Point-of-Load (PoL) DC DC Converter delivering 2.5V at 3A output from a 4.5V to 5.5V input range. It is designed for ITE (Commercial) applications with a through hole mounting type and a 12-SIP Module package. This model is part of the PT6400 series and is currently classified as obsolete. For continued production, maintenance, or design-in support, identification of suitable substitute parts is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for DC DC converter modules is strictly defined by identical or compatible electrical and mechanical parameters. These include: type (Non-Isolated PoL Module), number of outputs (1), output voltage (2.5V), maximum output current (3A), input voltage range (minimum ≤ required, maximum ≥ required), mounting type (Through Hole), package (12-SIP Module), and compliance with RoHS and REACH standards as well as matching MSL classification for manufacturing compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection of R-532.5PA as a substitute for PT6409P is justified based on full compliance with RoHS3, unaffected REACH status, identical MSL rating, and matching electrical and mechanical specifications specifically across input voltage (overlapping range), output voltage, output current, mounting method, package type, and application category. R-532.5PA is active and available in inventory, making it suitable for immediate replacement needs for designs utilizing PT6409P.

Frequently Asked Questions (FAQ)

Q1: What are the primary parameters considered for DC DC converter substitution?
Key parameters include output voltage, output current, input voltage range, number of outputs, mounting type, package type, and regulatory compliance (RoHS, REACH, MSL).

Q2: Does PT6409P and its substitute R-532.5PA support the same mounting and package dimensions?
Both components use through hole mounting and a 12-SIP Module package, supporting direct mechanical compatibility.

Q3: Are compliance and certification statuses equivalent?
Both models are ROHS3 Compliant, REACH Unaffected, and rated MSL 1 (Unlimited), ensuring manufacturing and regulatory equivalence.

Q4: Is there an input voltage range difference?
PT6409P operates from 4.5V to 5.5V. R-532.5PA accepts a wider input range from 4.5V to 18V, fully covering the PT6409P requirement.

Q5: Can R-532.5PA be used in all PT6409P application scenarios?
Based strictly on input voltage, output voltage, output current, mounting type, package, and compliance, R-532.5PA is specified for ITE (Commercial) applications equivalent to PT6409P.
