PKB4717PINB Equivalent & Substitute Parts Reference Guide

Part Overview

Flex Power Modules PKB4717PINB is a DC DC converter classified as an isolated module, specifically designed for ITE (Commercial) applications. It offers a single output of 7.2V at up to 10.5A, with an input voltage range from 36V to 75V and a maximum power output of 76W. The product features adjustable output, remote on/off, remote sense, and is mounted using through-hole technology in an Eighth Brick package. The PKB4717PINB is currently marked as obsolete, making the identification of equivalent or substitute models imperative for continued design, production, and maintenance processes.

Substitute Part Grouping Explanation

Substitutes for PKB4717PINB are identified strictly on the following parameters: input voltage range (36V to 75V), output configuration (single output), isolation voltage (2.25 kV), application (ITE commercial), control features (Enable, Active Low), product compliance and certifications (CB, CSA, IEC, TUV, UL, RoHS3, REACH), and standard number (62368-1). Substitute models must match these required parameters to ensure functional and mechanical compatibility in engineering applications.

Engineering Selection Recommendations

PKB4717PINB is designated as obsolete. Substitute selection is based on product status (Active), equivalent compliance (ROHS3, REACH, CB, CSA, IEC, TUV, UL), and identical standard number (62368-1). Substitute models meeting these requirements do not introduce compliance or certification disparity.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for approved substitute selection of PKB4717PINB?
A1: Input voltage range (36V to 75V), output configuration (single output), isolation voltage (2.25 kV), application (ITE commercial), control features (Enable, Active Low), and compliance certifications (CB, CSA, IEC, TUV, UL, ROHS3, REACH, 62368-1).

Q2: How does package type affect PKB4717PINB substitution?
A2: PKB4717PINB uses an Eighth Brick through-hole package, while substitutes like PKU4717ESI use Sixteenth Brick surface mount. Mechanical integration depends strictly on these supplied package dimensions and mounting type.

Q3: Are substitutes for PKB4717PINB guaranteed to match output power and voltage?
A3: Substitute models only provide the output power and voltage values specified in the part listing. Users should confirm the stated electrical specifications against system requirements.

Q4: What certifications are retained in equivalent substitute models?
A4: Certifications and approvals specified (CB, CSA, IEC, TUV, UL, ROHS3, REACH) are matched in substitute models per provided parameters.

Q5: Is moisture sensitivity level (MSL) a substitution concern for PKB4717PINB?
A5: Packaging and MSL information are included as supplied. PKB4717PINB is noted as not applicable, while substitute PKU4717ESI is specified as MSL 3 (168 hours). Selection should adhere to these stated levels.
