Equivalent & Substitute Parts for PKB5110WPI

Part Overview

The Flex Power Modules PKB5110WPI is an isolated DC-DC converter designed for commercial ITE applications. It offers a single regulated output of 3.3V at up to 30A with a wide input voltage range of 18V to 75V. Key features include remote on/off control, remote sense, and adjustable output. The device is housed in an Eighth Brick package with through-hole mounting and supports multiple international safety standards. The PKB5110WPI is listed as obsolete, making it necessary for engineers to identify alternative models with matching electrical, mechanical, and regulatory specifications to ensure continuity in new designs or maintenance of existing systems.

Selection should be based on availability and confirmed regulatory compliance as per documented parameters.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting PKB5110WPI in an application?
A1: The substitution criteria require matching electrical parameters (input voltage range, output voltage, output current, isolation rating), mechanical details (Eighth Brick package, through-hole mounting, dimensions), application category (ITE commercial), control features (Enable, Active Low), safety approvals, RoHS/REACH compliance, and operating temperature range.

Q2: Can PKB4110CPI or PKB4110DPI be used in the same board layout as PKB5110WPI?
A2: Both PKB4110CPI and PKB4110DPI utilize the Eighth Brick package and through-hole mounting. Their physical dimensions and packaging enable mechanical compatibility with layouts designed for PKB5110WPI.

Q3: Are the substitute parts environmentally compliant like PKB5110WPI?
A3: PKB4110CPI and PKB4110DPI are listed as ROHS3 Compliant and REACH Unaffected, matching the environmental compliance status of PKB5110WPI.

Q4: Do the substitute parts have the same safety standard approvals?
A4: PKB4110CPI and PKB4110DPI are certified by CB, CSA, IEC, TUV, and UL, conforming to standard number 62368-1 as required for PKB5110WPI.

Q5: Is there a difference in operating temperature or efficiency between the original and substitute models?
A5: Both substitutes offer higher maximum operating temperatures (-40°C ~ 125°C) and improved efficiency compared to PKB5110WPI (-40°C ~ 110°C, 90%). These can be confirmed in specification matching.
