Equivalent & Substitute Parts for PBO-8-5-B

Part Overview

The PBO-8-5-B is an open frame AC/DC converter manufactured by CUI Inc. It provides a single 5V DC output at up to 1.6A from a wide input range (85 ~ 305 VAC, 100 ~ 430 VDC). With a power output of 8W, through hole, right angle mounting and a 16-SIP module package, this converter is suitable for household appliances and commercial ITE applications. The product status is listed as obsolete, making it necessary to identify substitute models to fulfill ongoing requirements for electrical and mechanical integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based on direct equivalence and compliance with essential electrical and mechanical parameters. Key parameters include matching input voltage range, output voltage (5V), mounting type, package/case dimensions, approval certifications, and RoHS compliance. Substitute parts must provide at least the same or higher current output and conform to the same standards and agency listings as specified.

Parameter Comparison

Engineering Selection Recommendations

Substitute selection for PBO-8-5-B is primarily justified by product obsolescence and inventory availability. The recommended substitute, PBO-15C-5-B, matches all essential compliance and certification standards (CE, cURus, UL), retains the same RoHS and ECCN status, and aligns with mechanical mounting and package specifications. The substitute provides a higher output current and power, meeting or exceeding original application requirements within the defined standards and regulations.

Frequently Asked Questions (FAQ)

Q1: What criteria were used for identifying substitute parts for PBO-8-5-B?
Substitute identification is based strictly on matching input and output voltage, current rating, mounting type, package/case, approval agency certifications, and RoHS compliance.

Q2: Can PBO-15C-5-B be used as a direct replacement in applications designed for PBO-8-5-B?
PBO-15C-5-B shares equivalent input voltage range, output voltage, mounting style, and package format, with matching or superior output current and power ratings.

Q3: Are there differences in agency approvals between the main and substitute part?
PBO-15C-5-B includes an additional UL approval, supplementing CE and cURus certifications present on PBO-8-5-B.

Q4: Do the mechanical dimensions of the substitute part ensure direct compatibility?
Both devices use the 16-SIP module, 6 leads format. The substitute is marginally wider, but retains the same length and height for layout compatibility.

Q5: What compliance statuses do both products share?
Both are RoHS compliant, have the same ECCN, and meet standards 60335-1 and 62368-1. The substitute also lists unaffected REACH status.
