PKU4511PI Equivalent & Substitute Parts Reference

Part Overview

The Flex Power Modules PKU4511PI is an isolated DC-DC converter module designed for ITE (Commercial) applications, providing 1 output at 5V, 10A, with a power rating of 50 W. The module features adjustable output, remote on/off and remote sense, with enable (active low) control. It is ROHS3 compliant and REACH unaffected. With certifications including CB, CSA, IEC, TUV, and UL (62368-1), it is suitable for high-reliability standards. The PKU4511PI is now classified as “Obsolete,” necessitating the identification of substitute products that match its key electrical, mechanical, and regulatory parameters for continued design and maintenance support.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is strictly governed by matching electrical and mechanical parameters, regulatory compliance, and certification. Critical parameters that allow substitution within the Sixteenth Brick DC-DC Isolated Module category include:

• Output configuration (number of outputs, voltage, current, power rating)
• Input voltage range
• Isolation voltage
• Control features and certifications
• Mounting type and package dimensions
• Environmental compliance (RoHS, REACH)
• Certification (CB, CSA, IEC, TUV, UL, Standard 62368-1) Matching these criteria ensures direct pin-for-pin or functionally equivalent replacement within the given application context.

Parameter Comparison

Engineering Selection Recommendations

Selection of PKU5511ESI as a substitute for PKU4511PI is enabled by product status, with PKU4511PI marked as “Obsolete” and PKU5511ESI as “Active.” Both modules comply with ROHS3, REACH, and maintain identical international regulatory certifications (CB, CSA, IEC, TUV, UL to 62368-1). Substitute selection remains valid in applications requiring adherence to compliance and approval agency criteria provided in the input.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a substitute DC-DC converter module in the Sixteenth Brick category?
Only the input voltage range, output voltage and current, power rating, isolation voltage, control features, package, mounting type, certifications, and environmental compliance parameters provided should be matched.

Q2: Can PKU5511ESI replace PKU4511PI in commercial ITE applications?
PKU5511ESI matches the critical parameters, certification, compliance status, and package size as provided, enabling its use as a substitute in ITE (Commercial) applications.

Q3: Does the mounting type affect interchangeability between PKU4511PI (Through Hole) and PKU5511ESI (Surface Mount)?
Mounting type is a dimension of mechanical compatibility; both parts are Sixteenth Brick format, but must be selected in accordance with the required board assembly process as specified in the input.

Q4: Do both modules meet RoHS and REACH requirements?
Both PKU4511PI and PKU5511ESI are ROHS3 compliant and REACH unaffected according to the provided parameters.

Q5: Are certification and approval agency parameters aligned for substitute use?
Both modules are certified to CB, CSA, IEC, TUV, UL in accordance with standard number 62368-1, fulfilling regulatory and approval criteria for direct substitution.
