Equivalent & Substitute Parts Reference: PKB5110WPIHS

Part Overview

The Flex Power Modules PKB5110WPIHS is an isolated DC-DC converter module featuring a single 3.3V, 30A output, suitable for ITE (Commercial) applications. The product offers adjustable output, baseplate, remote On/Off, and remote sense functions. This model is obsolete, necessitating identification of suitable substitute parts that strictly match key electrical, mechanical, and compliance parameters for continued system integration.

Substitute Part Grouping Explanation

Substitute parts are grouped strictly by matching essential electrical, environmental, compliance, and mechanical parameters. The criteria are:

Output Voltage and Current
Input Voltage Range
Power Rating
Isolation Voltage
Number of Outputs
Features
Operating Temperature Range
Efficiency
Mounting Type
Package/Case Dimensions
Compliance (Approval Agency, Standard Number, RoHS, REACH)
Product Availability Status

These parameters determine direct interchange based on system needs and regulatory requirements.

Engineering Selection Recommendations

Substitute selection is based on verifying product status to avoid obsolete components and confirming the required compliance credentials (RoHS, REACH, and approval agencies per 62368-1). Both PKB4110CPIHS and PKB4110DPI are active with equivalent regulatory status and matching package/mechanical parameters.

Frequently Asked Questions (FAQ)

Q1: What are the main substitution criteria for PKB5110WPIHS?
A1: Substitution must match output configuration, input voltage range, isolation voltage, package type, approval agency compliance, operating temperature, RoHS/REACH status, and mounting type.

Q2: Can PKB4110CPIHS and PKB4110DPI be directly used in place of PKB5110WPIHS?
A2: PKB4110DPI provides a matching output voltage and current range and meets mechanical, compliance, and environmental parameters. PKB4110CPIHS meets all parameters except for output voltage.

Q3: What are the package and mounting considerations for these DC-DC converter modules?
A3: All referenced parts use the Eighth Brick through hole package with dimensions consistent to replace PKB5110WPIHS mechanically.

Q4: Are all substitutes compliant with the same regulatory standards?
A4: All substitutes are compliant with RoHS3, REACH, and standard number 62368-1, with approval agency credentials listed in the parameter comparison.

Q5: What is the significance of product status in selecting substitutes?
A5: Only active products should be selected to ensure continued availability and support. PKB5110WPIHS is obsolete; PKB4110CPIHS and PKB4110DPI are active.
