Equivalent & Substitute Parts for VWRAS2-D48-D9-SIP

Part Overview

The VWRAS2-D48-D9-SIP from CUI Inc. is an isolated module DC-DC converter, delivering two outputs: +9V and -9V at up to 111mA each from a 36V–72V input. Rated at 2W, packaged in an 8-SIP Module with 7 leads, and RoHS compliant, it is intended for ITE (Commercial) applications and features short circuit protection. With an obsolete product status, it is necessary to identify substitute models to ensure continued availability and maintain compatibility with existing systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is strictly based on the following electrical and mechanical parameters: input voltage range (36V–72V), output voltages (+9V and -9V), output current (111mA per channel), power rating (2W), isolation voltage (≥1.5kV), features (SCP), temperature range (-40°C ~ 85°C), mounting type (Through Hole), and package (8-SIP Module, 7 Leads). Only models matching these criteria are classified as direct substitutes within the isolated module DC-DC converter product category.

Parameter Comparison

Engineering Selection Recommendations

The VWRAS2-D48-D9-SIP is classified as obsolete. The RS-4809D/H2 from Recom Power matches the core electrical, mechanical, and compliance parameters, including RoHS and REACH certifications, operating temperature range, mounting, package case, and output specifications. It is designated as an active product and directly meets the requirements for substitute selection.

Frequently Asked Questions (FAQ)

Q1: What defines compatibility for VWRAS2-D48-D9-SIP substitute selection?
Substitute models must match input voltage, output configuration, current capability, power rating, isolation voltage, footprint, and compliance certifications.

Q2: Is the RS-4809D/H2 mechanically compatible with VWRAS2-D48-D9-SIP?
Both models use the 8-SIP Module with 7 leads and have nearly equivalent physical dimensions, enabling direct mechanical interchangeability.

Q3: Are there differences in electrical performance between VWRAS2-D48-D9-SIP and RS-4809D/H2?
Both deliver identical output voltages and currents; differences include a higher isolation voltage and efficiency in RS-4809D/H2, within acceptable substitution parameters.

Q4: Does substituting affect environmental or compliance status?
Both parts are RoHS and REACH compliant; RS-4809D/H2 holds ROHS3 Compliant status.

Q5: Must new qualification testing be performed when switching parts?
Selection is based strictly on matching provided parameters. No further criteria are presented in this engineering reference page.
