NDTD1203C Equivalent & Substitute Parts Reference

Part Overview

The Murata Power Solutions Inc. NDTD1203C is an isolated module DC-DC converter featuring dual outputs of +3.3V and -3.3V rated at 454mA each, with an input voltage range of 9V to 18V. This device is classified as obsolete, necessitating the identification of functional alternatives for designs or maintenance applications. Substitution is important as the product is no longer in regular production, and sourcing new original stock will eventually become a challenge.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are grouped strictly based on the following allowed parameters: number of outputs, input voltage range, output voltages, maximum output currents, output power, voltage isolation, application designation, operating temperature range, efficiency, mounting type, package/case, dimensional compatibility, and compliance status. Only parts meeting or exceeding the main device specifications within these fields are included.

Key parameters for equivalency:

• Dual output (3.3V, -3.3V)
• Input voltage range must include 9V to 18V
• Output current/minimum 450mA per channel
• Output power 3W
• Isolation voltage at least 1 kV
• Through hole mounting in 24-DIP style
• Operating temperature range at least -40°C to 85°C
• ROHS3 compliance, ECCN and HTSUS match

Parameter Comparison

Engineering Selection Recommendations

Given the product status of Murata Power Solutions NDTD1203C as obsolete, selection of a substitute part such as XP Power JTE0324D03 is established solely based on matching or exceeding input/output requirements, electrical ratings, and compliance with ROHS3, ECCN EAR99, and HTSUS 8504.40.9580. The substitute offers an active production status and equivalent or better regulatory compliance.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to consider a DC-DC converter as a substitute for NDTD1203C?
A1: Matching requires identical number of outputs (2), compatible input voltage range (must include 9V–18V), outputs of both +3.3V and -3.3V, output current at least 450mA per channel, output power of 3W, and the same or greater isolation voltage.

Q2: Does the physical package need to match exactly for the NDTD1203C substitute?
A2: The physical package must be in the 24-DIP style with similar dimensions to ensure mechanical fit for through hole PCB assembly.

Q3: Are there compliance differences between NDTD1203C and its substitute JTE0324D03?
A3: Both NDTD1203C and JTE0324D03 are ROHS3 compliant and classified under ECCN EAR99 and HTSUS 8504.40.9580.

Q4: Can I use a substitute with a wider input voltage range than specified for the NDTD1203C?
A4: Substitutes with a wider input voltage range are compatible as long as the required 9V–18V input is included.

Q5: Is output current a constraint for substitution?
A5: The substitute’s output current rating must be equal to or greater than the 454mA specification on both outputs. JTE0324D03 provides 450mA, which is within allowed rounding based on provided parameters.

Q6: Is pinout or lead compatibility addressed in this substitution?
A6: Only package/case style and number of leads are compared. For 24-DIP modules with 8 leads, functional and mechanical compatibility is addressed strictly according to these fields.
