Equivalent & Substitute Parts for ISE0303A-TR

Part Overview

ISE0303A-TR is a DC-DC converter manufactured by XP Power, categorized as an isolated module with 1W output power, 3.3V output voltage, and surface mount packaging (8-SMD, 5 Leads). The converter is designed for ITE (Commercial) applications, features short circuit protection, and operates in a -40°C to 105°C temperature range. The part is RoHS3 compliant and holds inventory status as "Obsolete."
Given the obsolete status, identification of equivalent or substitute DC-DC converter modules with matching electrical and mechanical parameters is required to ensure continued system functionality and compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships are strictly established based on matching electrical and mechanical parameters provided for this DC-DC converter category. The key substitution criteria are: isolated module type, single output, input voltage range (2.97V to 3.63V), output voltage (3.3V), maximum output current (303mA), output power (1W), voltage isolation, features (SCP), application (ITE, commercial), package (8-SMD Module, 5 Leads), mounting type (surface mount), operating temperature range (-40°C to 105°C), and compliance status (RoHS/MSL/HTSUS). Only parts with parameters equal to or exceeding the original are considered. No additional criteria or assumptions are applied.

Engineering Selection Recommendations

The ISE0303A-TR is marked obsolete. The direct substitute PES1-S3-S3-M-TR from CUI Inc. maintains key electrical, mechanical, compliance, and environmental parameters as required. Substitute maintains RoHS compliance and MSL 1 (unlimited). The substitute part presents an active product status and is available in compatible packaging and casing.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are applied for ISE0303A-TR?
A1: Substitutes must strictly match or exceed the following: isolated module type, single output, input voltage range (2.97V to 3.63V), output voltage (3.3V), output current (303mA), power rating (1W), surface mount packaging (8-SMD, 5 Leads), specified features, application (ITE), and compliance standards.

Q2: Are the substitute parts pin-to-pin compatible with the original?
A2: The substitute PES1-S3-S3-M-TR uses the same 8-SMD Module, 5 Leads package and surface mount configuration as ISE0303A-TR.

Q3: Does the substitute meet the environmental and compliance requirements?
A3: PES1-S3-S3-M-TR is RoHS compliant and has MSL 1 (unlimited), matching the original’s compliance profile.

Q4: Will the substitute support the original’s operating environment?
A4: The substitute supports an operating temperature range of -40°C to 105°C (with derating), consistent with the original part's range.

Q5: Is there a size or dimension difference to consider?
A5: Both parts maintain the same length and width; PES1-S3-S3-M-TR has a height of 7.3mm compared to the original's 7.0mm. Both use the same standard surface mount footprint.

Q6: Is there a difference in performance characteristics?
A6: The substitute matches or exceeds the original electrical parameters, including efficiency, voltage isolation, and maximum ratings as provided.
