PKB4910API Equivalent & Substitute Parts Reference

Part Overview

The Flex Power Modules PKB4910API is an isolated DC-DC converter module with a single 3.3V output at up to 30A, rated for 99W. It features an 8th brick package, through-hole mounting, and extensive safety approvals for ITE (Commercial) use. The status of the PKB4910API is Last Time Buy, which indicates it is approaching end-of-life and ongoing production is not guaranteed. Identifying suitable equivalent or substitute models is essential to ensure continued design manufacturability, inventory resilience, and long-term product support in applications where this power level and package are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for DC-DC converter modules within the isolated module product category is governed by exact alignment of electrical and mechanical parameters. The key parameters used to determine substitutability are: input voltage range, output voltage, maximum output current, power rating, voltage isolation rating, features (adjustable output, remote on/off, remote sense), mounting type (through hole), package size (Eighth Brick), safety approvals, RoHS and REACH compliance, operating temperature, and control features. Only parts that match or exceed these criteria are included as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between PKB4910API and PKB4110DPI should be based on continued product status and regulatory compliance. PKB4910API is Last Time Buy and PKB4110DPI is Active, supporting long-term design continuity. Both parts share full RoHS3 and REACH compliance, identical industry certifications (62368-1, CB, CSA, IEC, TUV, UL), and matching HTSUS/ECCN classifications. Use only the provided parameters when considering alternatives for continued compliance and supply chain stability.
