PKB4810PINB Equivalent & Substitute Parts Reference

Part Overview

The Flex Power Modules PKB4810PINB is an isolated DC-DC converter module delivering a regulated 3.3V output at up to 25A with a 36V–75V input range, 83W output power, and 2.25kV isolation. It features adjustable output, remote on/off, and remote sense, targeting ITE (Commercial) applications, with through-hole mounting in an Eighth Brick package. The PKB4810PINB is classified as obsolete, which requires identification of appropriate equivalent or substitute DC-DC converter modules to ensure ongoing design, repair, and supply consistency.

Key Parameters

Substitute Part Grouping Explanation

The substitute part is selected strictly by matching the following parameters: DC-DC isolated module type, 1 output, input voltage range (36V–75V), output voltage (3.3V), package (Eighth Brick, Through Hole), equivalent or higher output current, equivalent or higher isolation voltage, feature set (Adjustable Output, Remote On/Off, Remote Sense), operating temperature including or exceeding that of the main part, compliance with the same safety approvals (CB, CSA, IEC, TUV, UL), RoHS3 compliance, MSL classification, REACH status, and 62368-1 standard.

Parameter Comparison

Engineering Selection Recommendations

Engineering selection is guided by the obsolete status of PKB4810PINB. Substitute selection uses the PKB4110DPI, which is RoHS3 compliant, covered by the same set of safety approvals (CB, CSA, IEC, TUV, UL), and maintains the same input/output electrical parameters, control features, and mechanical form factor as defined by the Eighth Brick package and through-hole mounting. The PKB4110DPI meets all listed compliance, environmental, and certification requirements present for the original part.

Frequently Asked Questions (FAQ)

Q1: What are the key substitution criteria between PKB4810PINB and PKB4110DPI?
A1: Substitute selection is determined strictly by matching DC-DC converter type, number of outputs, input voltage range, output voltage, output current (equal or higher), package (Eighth Brick, Through Hole), features, operating temperature range, regulatory approvals, RoHS/REACH status, and mechanical dimensions.

Q2: Is there any difference in output performance between PKB4810PINB and PKB4110DPI?
A2: Both parts supply a regulated 3.3V output; PKB4110DPI supports a higher maximum output current (40A vs. 25A) and higher output power (132W vs. 83W), with all other functional and electrical parameters held constant where specified.

Q3: Are PKB4810PINB and PKB4110DPI mechanically compatible?
A3: Both parts utilize the Eighth Brick form factor (Through Hole) with compatible size. The only dimensional variance is overall height (PKB4110DPI: 0.38" vs. PKB4810PINB: 0.32").

Q4: What approvals and compliance statuses do both parts share?
A4: Both have CB, CSA, IEC, TUV, and UL approvals, meet standard 62368-1, are classified as RoHS3 compliant, with “Not Applicable” MSL, “REACH Unaffected” status, ECCN EAR99, and share the same HTSUS code.

Q5: Can PKB4110DPI be used in ITE (Commercial) applications?
A5: PKB4110DPI is designed for ITE (Commercial) applications and includes the same application suitability as PKB4810PINB as explicitly specified.
