Equivalent & Substitute Parts for ULE-3.3/20-D24P-C

Part Overview

The Murata Power Solutions ULE-3.3/20-D24P-C is an obsolete isolated DC-DC converter module. This device provides a single regulated 3.3V output at up to 20A from a 18V to 36V input range and is primarily used in ITE (Commercial) applications. With its obsolete product status, sourcing direct replacements may be increasingly difficult, necessitating the identification of compatible alternative parts with matching or superior electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined strictly based on key parameters: module type (Isolated Module), single output (1), output voltage (3.3V), output current (≥20A), input voltage range (must encompass or match 18V – 36V), isolation voltage (2.25 kV), mounting (Through Hole), package type (8-DIP Module), key functional features (Remote On/Off, OCP, OTP, UVLO), and RoHS compliance. Only alternatives matching these criteria are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The ULE-3.3/20-D24P-C is classified as obsolete, while the substitute, ESTW025A0F4Z, is listed as active and RoHS Compliant. Both devices offer equivalent isolation and application ratings and comply with environmental and export regulatory statuses as provided. Substitute selection is based solely on matching part status and compliance with the specified certifications.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine suitable substitutes for the ULE-3.3/20-D24P-C?
A1: Substitutes are determined strictly by matching key electrical ratings (input/output voltage and current, isolation voltage), mechanical compatibility (mounting, package size), operational features, and compliance with RoHS requirements.

Q2: Are mechanical package differences a concern during substitution?
A2: Both main and substitute parts use the through hole, 8-DIP Module format. Dimensional differences are specified for mechanical review.

Q3: Does the operating temperature range impact substitutability?
A3: Both the original and substitute part specify an identical operating temperature range of -40°C to 85°C.

Q4: Is functional feature coverage consistent between the original and substitute parts?
A4: Substitutes are selected to match or exceed functional features, including remote operation, protection functions, and enable controls as specified.

Q5: Is RoHS status maintained in substitution?
A5: Both the ULE-3.3/20-D24P-C and ESTW025A0F4Z are RoHS Compliant.
