QLS25ZD-NTS2 Equivalent & Substitute Parts Reference

Part Overview

The QLS25ZD-NTS2 from Bel Power Solutions is an isolated DC-DC converter module designed for ITE (Commercial) applications. It offers a single 2.5V output at up to 25A, with a wide input range of 36V to 75V and a power rating of 63W. The module features remote on/off, OCP, OTP, OVP, and UVLO protections, is ROHS3 compliant, and operates over a wide temperature range. As the QLS25ZD-NTS2 is now obsolete, identifying suitable alternative models is essential for ongoing production support, maintenance, and new designs requiring compatible DC-DC converter solutions.

Substitute Part Grouping Explanation

Substitute components are determined strictly by matching or exceeding the original device’s key electrical and mechanical parameters. Substitute grouping is based on the following criteria: input voltage range (36V–75V), output voltage (2.5V), number of outputs (1), maximum output current (≥25A), power rating (≥63W), voltage isolation (1.5 kV), mounting type (through hole), package dimensions, thermal range, and regulatory compliance. Mechanical compatibility and RoHS/REACH compliance are also considered to ensure fit and regulatory alignment.

The substitute part also holds appropriate regulatory classifications. Selection can be based directly on these compliance, certification, and product status factors as provided.

Frequently Asked Questions (FAQ)

Q1: On what basis can the IQL48060A025V-008-R serve as a substitute for the QLS25ZD-NTS2?
A1: The IQL48060A025V-008-R matches the required input voltage range, output voltage, single output, voltage isolation, application type, mounting method, and basic regulatory compliance as the QLS25ZD-NTS2.

Q2: Are the mechanical dimensions and mounting fully compatible?
A2: Both modules have the same length and width and use through-hole, quarter brick packages. Height differs slightly.

Q3: Does the substitute have higher capability in any parameter?
A3: The IQL48060A025V-008-R provides higher output current (60A) and total power (150W) than the QLS25ZD-NTS2, while meeting or exceeding all other key specifications provided.

Q4: Is there any difference in compliance or environmental qualification?
A4: Both the QLS25ZD-NTS2 and IQL48060A025V-008-R are RoHS and REACH compliant; both share the same ECCN and HTSUS classifications.

Q5: What should be considered for inventory and product status?
A5: The QLS25ZD-NTS2 is obsolete; the IQL48060A025V-008-R is active and available in inventory.
