Equivalent & Substitute Parts Reference for PBO-3-S15-B

Part Overview

The PBO-3-S15-B is an AC/DC Converter manufactured by CUI Inc. in the Open Frame configuration, belonging to the PBO-3 (3W) series. It provides a single 15V output at up to 200mA, accepting input voltages of 85 ~ 305 VAC or 70 ~ 430 VDC. The device offers a 3W output with an efficiency of 78% and is specified for operation from -40°C to 85°C (with derating). The part has been designated as Obsolete, requiring the identification of substitute and equivalent models for designs needing ongoing component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching core electrical and mechanical parameters: single 15V output, 3W power rating, 200mA maximum output current, input range including 85 ~ 305 VAC, operating temperature -40°C ~ 85°C, through hole mounting, and RoHS compliance. The substitute part, PSK-3D-15, is identified by the manufacturer, meets these criteria regarding input range, output characteristics, mounting type, power rating, and compliance.

Parameter Comparison

Engineering Selection Recommendations

The PBO-3-S15-B is obsolete; for ongoing designs and production, select an active status component. PSK-3D-15 maintains RoHS and MSL 1 (Unlimited) compliance and carries agency approvals (CE, cURus). Substitution maintains compliance with relevant technical and safety standards provided. Certification schemes differ and must align with project requirements based on the provided standards data.

Frequently Asked Questions (FAQ)

Q1. What are the main substitution criteria between PBO-3-S15-B and PSK-3D-15?
A1. Substitution is based on identical output voltage (15V), maximum output current (200mA), power (3W), input voltage ranges (VAC overlap: 85 ~ 305), through hole mounting, RoHS status, and operating temperature.

Q2. Can I substitute an open frame module with an enclosed type as with PBO-3-S15-B and PSK-3D-15?
A2. Both modules are PCB mount. Module enclosure type (Open Frame vs Enclosed) influences only form factor and application environment, not electrical compatibility when other parameters are maintained.

Q3. Are there differences in mechanical package dimensions or layouts to consider?
A3. Yes. PBO-3-S15-B uses a 12-SIP module, 6 leads, 1.38" x 0.71" x 0.43". PSK-3D-15 uses a 5-DIP module, 4 leads, 1.00" x 1.00" x 0.69". Pin layout and board fit must conform based strictly on available mechanical data.

Q4. Do input voltage differences affect substitution eligibility?
A4. Both modules operate with 85 ~ 305 VAC input; ensure input voltage range requirements are within the overlap specified.

Q5. Is regulatory compliance maintained with the substitute PSK-3D-15?
A5. The PSK-3D-15 meets CE and cURus certifications, and is ROHS3 compliant; standards and agency approval numbers differ and must be matched per mandatory compliance needs.

Q6. What about obsolete versus active part selection?
A6. For ongoing designs, select active components. PSK-3D-15 is active, maintaining supply chain availability, whereas PBO-3-S15-B is obsolete.
