Equivalent & Substitute Parts for VIBLSD1-S12-S9-SIP

Part Overview

The VIBLSD1-S12-S9-SIP by CUI Inc. is an isolated DC-DC converter module, offering 1 output of 9V at up to 111mA, designed for ITE (Commercial) applications. It features single output, through-hole mounting, 1W power rating, and a 1kV isolation voltage. Product status is active, with RoHS compliance and unlimited moisture sensitivity level (MSL 1). The need for alternatives primarily arises from requirements for identical electrical parameters, compliance, and similar mechanical footprints when integrating into existing designs or ensuring supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for the VIBLSD1-S12-S9-SIP DC-DC converter is based strictly on the following parameters:

• Voltage input range (11.4V - 12.6V)
• Output voltage (9V)
• Output current (max 111mA)
• Power rating (1W)
• Number of outputs (1)
• Isolation voltage (minimum 1kV)
• Through-hole mounting and SIP package with compatible physical dimensions
• Operating temperature range (-40°C ~ 85°C)
• RoHS compliance and unlimited moisture sensitivity level

Substitutes included are confirmed to match or exceed these electrical, thermal, mechanical, and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both VIBLSD1-S12-S9-SIP and PQME1-S12-S9-S are active products from CUI Inc., with RoHS compliance and unlimited moisture sensitivity levels. The substitute part PQME1-S12-S9-S presents comparable electrical and mechanical characteristics, with a higher isolation voltage (1.5kV vs. 1kV) and similar efficiency. Both parts conform to commercial ITE applications, and each maintains consistent product compliance parameters (ECCN, HTSUS, RoHS). Select based on the required certifications and compatibility with relevant standards.

Frequently Asked Questions (FAQ)

Q: What determines a valid substitute for VIBLSD1-S12-S9-SIP?
A: Equivalent substitutes must match the main part's input/output voltage and current ratings, power rating, isolation voltage, physical SIP package type and dimensions, mounting method, operating temperature range, regulatory compliance, and moisture sensitivity level.

Q: Are mechanical package differences significant during substitution?
A: Substitute PQME1-S12-S9-S uses a 7-SIP module versus the main part's 6-SIP, but both modules use 4 leads and feature similar dimensions. Compatibility should be confirmed according to specified package dimensions.

Q: Do both parts comply with RoHS and similar international requirements?
A: Both VIBLSD1-S12-S9-SIP and PQME1-S12-S9-S are RoHS compliant and have a moisture sensitivity level of 1 (Unlimited).

Q: Is the isolation voltage difference between parts relevant for substitution?
A: PQME1-S12-S9-S features a higher isolation voltage (1.5kV) than the VIBLSD1-S12-S9-SIP (1kV), which meets or exceeds the main part's requirement.

Q: Are efficiency and operating temperature ranges matched between the alternatives?
A: Both converters support the specified operating temperature range of -40°C to 85°C. PQME1-S12-S9-S offers a slightly higher efficiency (73%) compared to VIBLSD1-S12-S9-SIP (72%).

Q: Can output and input parameters be relied on as identical between these parts?
A: Both parts provide one output at 9V/111mA, with input voltage ranges of 11.4V to 12.6V, matching required operational specifications.
