Datasheet Part Audit
Worked for 20 sec
I’m inspecting the current symbol and PCB land pattern first, including all six terminals and stored properties, before validating them against the manufacturer drawing.
Worked for 3 mins 24 sec
The stored Datasheet URL is already the official Bourns PTL-series PDF, so no URL change is needed. The six-hole footprint pattern matches the datasheet’s nominal terminal layout; I’m documenting metadata and symbol-label issues now.

PTL30-10R0-103B2 Part Datasheet Audit
Manufacturer: Bourns Official datasheet: https://www.bourns.com/docs/Product-Datasheets/PTL.pdf
Audit complete. The existing Datasheet URL is already the official Bourns PTL datasheet, and the six-hole footprint geometry matches the nominal manufacturer layout. Main issues are mismatched terminal numbering (
B1/E1/L1 versus B/E/L), incomplete pin descriptions/types, WIPER_ naming, and missing metadata such as tolerance, LED details, travel, and temperature range.Full findings: PTL30-10R0-103B2 Part Datasheet Audit

Table
| Field | Stored value | Audit result |
|---|---|---|
| MPN | PTL30-10R0-103B2 | Correct |
| Manufacturer | Bourns | Correct |
| Description | Res Carbon Film POT 10K Ohm 20% 0.1W(1/10W) (45 X 9 X 17mm) Pin Thru-Hole | Substantially correct but incomplete; it omits the integrated red LED, 30 mm travel, 10 mm lever, no-detent option, and B2 taper. |
| Part Type | Resistors | Too broad; this is a slide potentiometer with LED. |
| Subtype | Carbon Film | Consistent with the stored description, but the official PTL datasheet does not explicitly identify the resistive-element material in the reviewed data. |
| Resistance | 10 kΩ | Correct (103). |
| Tolerance | Not stored | Datasheet: ±20%. |
| Power rating | Not stored as a property | Datasheet: 0.1 W for 30 mm linear taper; 0.05 W for 30 mm audio taper. The description's 0.1 W agrees if B2 is treated as linear taper. |
| Package/case | Not stored | Custom through-hole slide potentiometer body; nominal body 45.0 × 9.0 mm, with 30 mm travel and 10 mm lever option. |
| Pin count | 6 terminals/pads | Correct. |
| Datasheet URL | Official Bourns PTL.pdf | Correct. |
| Distributor identifiers | None stored | Missing, but not a datasheet mismatch. |

Symbol and pin audit
Datasheet terminals are
1, 2, 3, B, E, and L:1and3: ends of the potentiometer element2: wiperB: LED positive/anodeE: LED negative/cathodeL: dummy mechanical terminal
Table
| Current symbol label | Current pin number | Expected datasheet terminal | Result |
|---|---|---|---|
| CCW | 1 | 1 | Electrically plausible, but CCW is not the datasheet terminal name and direction depends on the mechanical/viewing convention. Prefer terminal name 1 with a clear pin description. |
| WIPER_ | 2 | 2 | Function is correct; trailing underscore is a naming defect. |
| CW | 3 | 3 | Electrically plausible, but CW is not the datasheet terminal name and direction depends on the mechanical/viewing convention. Prefer terminal name 3 with a clear pin description. |
| + | B1 | B (+) | Function/polarity is correct, but pin number should be B, not B1, to match the datasheet and footprint source. |
| - | E1 | E (-) | Function/polarity is correct, but pin number should be E, not E1. |
| DUMMY | L1 | L | Function is correct, but pin number should be L, not L1. |
All six terminals currently have
Pin Type: Unspecified and no stored pin descriptions. Recommended descriptions are: Potentiometer terminal 1, Wiper, Potentiometer terminal 3, LED anode (+), LED cathode (-), and Dummy/mechanical terminal; no electrical connection.Footprint audit
The footprint source contains six plated through holes:
- Left group: terminal 1 at (0, 0), L at (0, 2.5), E at (0, 5), and terminal 2 at (0, -2.5)
- Right group: terminal 3 at (40, 0) and B at (40, 5)
- Hole diameter: 1.1 mm
- Pad diameter: 1.65 mm
- Body outline: 45 × 9 mm nominal
This matches the datasheet's nominal six-hole arrangement, 40.0 mm longitudinal spacing, 2.5 mm terminal pitch, 1.1 mm holes, and 45 × 9 mm body envelope. The 1.65 mm pad diameter is library-defined rather than specified by Bourns; it provides a 0.275 mm radial annular ring around the nominal 1.1 mm drill. Fabricator capability and maximum lead tolerance should be checked before production.
Flagged mismatches and omissions
- Pin numbers
B1,E1, andL1do not match datasheet terminalsB,E, andL. The footprint source uses B1/E1/L1 internally, but the manufacturer nomenclature is B/E/L. - Symbol labels
CCWandCWare not manufacturer-defined terminal names. Use terminal numbers 1 and 3, with optional directional descriptions only if the viewing convention is explicitly established. WIPER_has an unwanted trailing underscore.- All pin types are unspecified and all pin descriptions are absent.
- Description is incomplete: integrated red LED and key ordering-code features are omitted.
- Part type is overly generic (
Resistors). A potentiometer/variable resistor classification would be more accurate. - Tolerance, operating temperature, travel, taper, LED color, and power rating are not stored as explicit properties.
- No explicit package/case property or distributor identifiers are present.
- The footprint has no separate PCB mounting holes beyond the six terminal holes. The datasheet drawing references M2 features on the component; confirm whether enclosure/panel mounting or mechanical clearance needs to be represented in the consuming board design.
Overall assessment
The MPN, manufacturer, resistance, pin count, official datasheet URL, main body dimensions, terminal-hole geometry, and electrical connectivity are fundamentally consistent with the Bourns datasheet. The main corrections are metadata completeness and exact terminal nomenclature rather than a gross electrical or footprint geometry error.
