PBO-10-24-B Equivalent & Substitute Parts

Part Overview

The PBO-10-24-B is an open frame AC/DC converter manufactured by CUI Inc., rated for 10W output power with a single 24V output at 420mA maximum current. This unit accepts input voltage ranges of 85–305 VAC or 100–430 VDC and is designed for household appliances and ITE (commercial) applications. The product is classified as obsolete, necessitating identification of active equivalent models to maintain design continuity and ensure long-term component availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PBO-10-24-B is based on the following electrical and mechanical compatibility criteria:

Electrical Compatibility Requirements:

• Identical input voltage range: 85–305 VAC, 100–430 VDC
• Identical output voltage: 24V
• Output current capacity equal to or greater than 420mA
• Operating temperature range: −40°C to 85°C (With Derating)

Mechanical Compatibility Requirements:

• Open frame construction
• Single output configuration
• 16-SIP Module, 6 Leads package
• Through Hole mounting capability

Regulatory and Compliance Requirements:

• CE and cURus certifications (minimum)
• RoHS compliance
• Compliance with standards 60335-1 and 62368-1

The PBO-15C series converters meet all electrical and mechanical requirements for direct substitution. Both substitute models provide higher power ratings (15W versus 10W) and increased output current capacity (625mA versus 420mA), ensuring full backward compatibility with existing circuit designs while offering improved performance headroom.

Parameter Comparison

Engineering Selection Recommendations

PBO-15C-24-B is the primary substitute for the obsolete PBO-10-24-B. This model maintains identical mounting configuration (Through Hole, Right Angle) and package form factor, enabling direct mechanical and electrical replacement without PCB redesign. The PBO-15C-24-B carries active product status, ensuring long-term availability and supply chain continuity. It holds CE, cURus, and UL certifications, exceeding the regulatory compliance of the original part. The improved line regulation (±0.5% versus ±1%) and load regulation (±1% versus ±1.5%) provide enhanced output stability.

PBO-15C-24 serves as a secondary substitute option. This variant differs in mounting type (Through Hole only, without right angle specification) and offers ROHS3 compliance. Selection of this model requires verification that the application circuit board layout accommodates standard through-hole mounting without the right-angle configuration. Both substitute models provide 625mA output current capacity, exceeding the original 420mA specification, and deliver superior efficiency (85% versus 82%).

Frequently Asked Questions (FAQ)

Q: Can the PBO-15C-24-B directly replace the PBO-10-24-B without PCB modifications?

A: Yes. The PBO-15C-24-B maintains identical input voltage range (85–305 VAC, 100–430 VDC), output voltage (24V), package type (16-SIP Module, 6 Leads), and mounting configuration (Through Hole, Right Angle). No circuit redesign is required.

Q: What is the difference between PBO-15C-24-B and PBO-15C-24?

A: The primary difference is mounting type. The PBO-15C-24-B specifies Through Hole, Right Angle mounting, matching the original PBO-10-24-B configuration. The PBO-15C-24 specifies Through Hole mounting only. Selection depends on PCB layout requirements. Both models are electrically identical with 625mA output current capacity and 15W power rating.

Q: Is the higher output current (625mA versus 420mA) compatible with existing designs?

A: Yes. The substitute models provide increased current capacity while maintaining identical output voltage and input specifications. Existing load circuits drawing up to 420mA operate within the substitute models' rated capacity with additional performance margin.

Q: What regulatory certifications do the substitute models carry?

A: Both PBO-15C-24-B and PBO-15C-24 hold CE, cURus, and UL certifications. The original PBO-10-24-B held CE and cURus certifications only. The additional UL certification on substitute models provides expanded regulatory coverage.

Q: Are there any dimensional differences between the main part and substitutes?

A: Yes. The PBO-15C-24-B dimensions are 1.75" L × 0.94" W × 0.59" H (44.5mm × 24.0mm × 15.0mm), compared to the PBO-10-24-B at 1.75" L × 0.88" W × 0.59" H (44.5mm × 22.5mm × 15.0mm). The width differs by 0.06" (1.5mm). The PBO-15C-24 dimensions are 1.75" L × 0.59" W × 0.94" H (44.5mm × 15.0mm × 24.0mm). Verify PCB layout clearances before final selection.

Q: What is the RoHS compliance status of the substitute models?

A: The PBO-15C-24-B is RoHS Compliant. The PBO-15C-24 is ROHS3 Compliant. Both meet or exceed the RoHS compliance level of the original PBO-10-24-B.
