Part Datasheet Review and Verification
Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
Thought for 4 sec
I’ll review the part metadata and existing symbol/footprint, find and attach the official datasheet if missing, then verify pins and summarize any mismatches.
Thought for 38 sec
The part already has an official Bel datasheet URL set, so I’ll use that for the cross-check rather than changing the property.
Worked for 1 min 45 sec
Reviewed the part against the official Bel datasheet already set in the Datasheet URL property; no update was needed. The schematic pinout and named footprint pads match the datasheet pin functions, with no electrical pin mismatches found.
Open items:
- Exact footprint pad geometry/hole spacing should still be manually checked against the mechanical drawing before release.
- Use conservative datasheet values: no-load power 0.15 W max and 76% typical efficiency for the 5 V model.

Mechanical / Package Check
Datasheet identifies two mounting styles:
- Blank suffix: straight pin
- Y1 suffix: bent pin
For PBO-5F-5 without Y1 suffix, the expected style is straight pin.
Straight-pin mechanical dimensions from datasheet:
- Body: 26.40 mm × 14.73 mm × 11.00 mm
- Natural convection cooling
- 6 through-hole/SIP-style connections
The project description states a compact 6-SIP open-frame through-hole package, matching the datasheet. The PCB layout contains 6 named pads corresponding to the six electrical terminals, plus additional unnamed mount/mechanical pads. I could confirm the presence and names of the six electrical pads, but the available layout inspection output did not expose detailed pad coordinates/diameters in a compact form, so exact hole spacing and pad geometry were not fully verified against the mechanical drawing.
Pin / Symbol Cross-Check
Datasheet pin connections:
Table
| Pin | Datasheet Function | Project Terminal | Project Pin Type | Result |
|---|---|---|---|---|
| 1 | AC (L) | AC(L) | Input | Match |
| 2 | AC (N) | AC(N) | Input | Match |
| 3 | +V(CAP) | +V(CAP) | Passive | Match |
| 4 | -V(CAP) | -V(CAP) | Passive | Match |
| 5 | -Vo | -VO | Output | Match |
| 6 | +Vo | +VO | Output | Match |
Footprint Cross-Check
Observed named layout pads:
- AC(L)
- AC(N)
- +V(CAP)
- -V(CAP)
- -VO
- +VO
These match the six datasheet pin functions and schematic terminals. Additional unnamed mount/mechanical pads are present; these may be acceptable if they represent mechanical support geometry, but they are not part of the six electrical pin list in the datasheet.
Mismatches / Issues Flagged
- No schematic pin-number/function mismatches found.
- No part metadata mismatch found for MPN, manufacturer, part type, or datasheet URL.
- Package description matches the expected 6-pin straight through-hole/SIP style for PBO-5F-5.
- Footprint electrical pad names match the datasheet pin functions.
- Exact footprint geometry could not be fully verified from the inspected layout output because pad dimensions/coordinates were not visible in the compact result. A manual mechanical drawing check is recommended before release.
- The project description says no-load power consumption is “<0.1 W”; the datasheet table gives 0.1 W typical and 0.15 W max, while features text says <0.1 W. For conservative specifications, use 0.15 W max.
- The project description says “high efficiency up to 76%”; the datasheet table gives 76% typical for the 5 V model, while the series feature list says up to 81% across the family. For this exact MPN, use 76% typical.
Recommendation
The symbol and named footprint terminals are suitable based on the datasheet pinout. Before publishing/manufacturing, verify the physical footprint against the datasheet mechanical drawing: straight-pin body outline, pin hole size, and pin spacings including the 24.00 mm and 16.00 mm reference dimensions shown in the datasheet.
