PBO-10C-9 AC/DC Converter 9V 10W Equivalent & Substitute Parts

Part Overview

The PBO-10C-9 is an open frame AC/DC converter module manufactured by CUI Inc., designed to deliver 9V output at 1.1A maximum current with 10W power rating. This single-output converter accepts wide-range AC input (85–305 VAC) and DC input (100–430 VDC), making it suitable for household appliances and commercial ITE applications. The part is classified as obsolete, necessitating identification of active equivalent models to maintain design continuity and ensure ongoing component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete PBO-10C-9 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Output voltage must match: 9V
• Input voltage range must match or exceed: 85–305 VAC, 100–430 VDC
• Output current capacity must equal or exceed: 1.1A
• Power rating must equal or exceed: 10W

Mechanical Compatibility Criteria:

• Mounting type must be: Through Hole
• Package type must be compatible with 6-SIP or equivalent lead configuration
• Physical dimensions must fit within or be compatible with existing PCB layouts

Regulatory and Compliance Criteria:

• Approval agencies must include CE and cURus certifications as minimum
• RoHS compliance status must be maintained

The PBO-15C-9 qualifies as a direct substitute because it maintains identical output voltage (9V), identical input voltage range (85–305 VAC, 100–430 VDC), exceeds the output current requirement (1.67A vs. 1.1A), exceeds the power rating (15W vs. 10W), retains through-hole mounting, and holds all required regulatory certifications with enhanced compliance status (ROHS3 vs. RoHS Compliant).

Parameter Comparison

Engineering Selection Recommendations

The PBO-15C-9 is the manufacturer-recommended substitute for the obsolete PBO-10C-9. Selection of this substitute is supported by the following engineering factors:

Electrical Equivalence: The PBO-15C-9 maintains identical output voltage (9V) and input voltage range (85–305 VAC, 100–430 VDC), ensuring direct functional compatibility. The increased output current capacity (1.67A vs. 1.1A) and power rating (15W vs. 10W) provide design margin and do not introduce incompatibility with circuits designed for the original 10W module.

Regulatory and Compliance Status: The substitute part holds active product status with CE, cURus, and UL certifications, exceeding the minimum CE and cURus requirements of the original part. ROHS3 compliance supersedes the RoHS Compliant status of the original part, ensuring alignment with current environmental regulations.

Performance Enhancement: The PBO-15C-9 delivers improved line regulation (±0.5% vs. ±1%), improved load regulation (±1% vs. ±1.5%), and higher efficiency (82% vs. 80%), providing superior performance characteristics in the same functional category.

Physical Compatibility Consideration: The substitute part features a larger package footprint (44.5mm × 15.0mm × 24.0mm vs. 32.0mm × 15.0mm × 17.2mm). PCB layout verification is required to confirm that the increased length and height accommodate existing mounting holes and clearance requirements. The width dimension (15.0mm) remains identical.

Frequently Asked Questions (FAQ)

Q: Can the PBO-15C-9 directly replace the PBO-10C-9 in all applications?

A: The PBO-15C-9 is electrically compatible with applications designed for the PBO-10C-9, provided that PCB layout accommodates the larger physical dimensions (44.5mm length and 24.0mm height vs. 32.0mm and 17.2mm). The identical output voltage, input voltage range, and through-hole mounting type ensure functional compatibility. Physical verification of mounting hole spacing and component clearance is required before implementation.

Q: What is the significance of the higher power rating (15W vs. 10W) in the substitute part?

A: The increased power rating and output current capacity (1.67A vs. 1.1A) provide design margin and do not create incompatibility. Circuits designed for 1.1A at 9V will operate within the electrical specifications of the 15W module. The higher power rating indicates improved thermal performance and current delivery capability, which benefits system reliability.

Q: Are the regulatory certifications of the PBO-15C-9 equivalent to the original part?

A: The PBO-15C-9 exceeds the regulatory requirements of the PBO-10C-9. The original part holds CE and cURus certifications; the substitute adds UL certification. Both parts meet RoHS requirements, with the substitute meeting the enhanced ROHS3 standard. This represents an upgrade in regulatory compliance.

Q: What is the impact of improved line and load regulation in the substitute part?

A: The PBO-15C-9 provides tighter line regulation (±0.5% vs. ±1%) and load regulation (±1% vs. ±1.5%). These improvements result in more stable output voltage under varying input and load conditions. Applications sensitive to output voltage variation benefit from these enhanced specifications; applications tolerant of the original ±1% to ±1.5% variation remain fully compatible.

Q: Is the 16-SIP package of the substitute compatible with the 6-SIP footprint of the original part?

A: The package designations differ (16-SIP Module, 6 Leads vs. 6-SIP Module), and the physical dimensions are larger. The lead count and spacing must be verified against the original PCB design. While both are through-hole mounted modules, direct footprint compatibility cannot be assumed. PCB layout review is mandatory before component substitution.

Q: What inventory status should be considered when selecting between the main part and substitute?

A: The PBO-10C-9 is classified as obsolete with 1,088 pieces in stock. The PBO-15C-9 is active with 749 pieces in stock. For new designs and long-term production, the active PBO-15C-9 is the appropriate selection. For legacy system repairs requiring the exact original part, the remaining PBO-10C-9 inventory may be utilized if physical and electrical compatibility is confirmed.
