stopped brightness potentiometer — Alps Alpine — C470643 — board-l RV1 — rec-c470643

Everything below is projected from this project's stored component evidence. Values keep the exact wording, conditions, units and verdicts they were recorded with — nothing here is re-typed, corrected, or combined into an overall judgement about the part.

Coverage

Coverage is stated one domain at a time and is never rolled up. A domain marked open is a question that has not been answered; it is not a finding that the part is unsuitable. A record with no open domains has not thereby been declared safe.

identity and documented component characteristics

Coverage ID: cov-c470643-identity
Status: COVERED

Reason: Exact component identity and retained authoritative evidence; installation and firmware are separate.

Facts in this domain:

installed-seating-and-contact-life

Coverage ID: cov-c470643-open-0
Status: OPEN

Reason: Prototype the insertion part in the project 1.6 mm PCB; catalog notation Insertion (t: 2 mm) is retained without treating it as a mandatory substrate thickness; verify mounting, retention, underside clearance, contact behavior and operational life. Manufacturer catalog lists Manual soldering while JLCPCB lists Wave Soldering; resolve the permitted process before fabrication.

Facts in this domain:

fact-c470643-mounting
fact-c470643-life

Blocked by: no blocking fact is recorded. What is missing has not been reduced to a specific recorded fact, so the reason above is the whole of what is known.

adc-acquisition-calibration-and-firmware

Coverage ID: cov-c470643-open-1
Status: OPEN

Reason: The source impedance and RC values are design calculations; verify ADC sampling, reference, errata, endpoint/inversion calibration, startup and actual programmed behavior.

Facts in this domain:

fact-c470643-adc-design
fact-c470643-firmware-target

Blocked by: no blocking fact is recorded. What is missing has not been reduced to a specific recorded fact, so the reason above is the whole of what is known.

Facts

Each fact keeps its value, its unit, the conditions it holds under, where it came from and how far it has been confirmed as separate fields, because they are separate claims. A value without its conditions is not the same fact, and a verdict is about the evidence for the value, not about the part.

RECOMMENDED_OPERATION

The range the manufacturer intends the part to be used in. Always narrower than the absolute maximum.

PROJECT_STATE

A value this project recorded about how the part is used here — a chosen operating point, a net assignment, or a derived figure. Not a manufacturer specification.

`fact-c470643-mounting`	Integral black 14 mm knob (drawing diameter 14 +/-0.2 mm); 0.9 mm knob thickness; catalog notation Insertion (t: 2 mm); manual soldering	`NONE`	The project retains a 1.6 mm PCB: seating, retention and solderability require prototype validation; no added knob.

`fact-c470643-stops`	270 degrees +/-10 degrees; stopper strength 70 mN m	`NONE`	Physical stops; clockwise electrical endpoint depends on the viewing/mounting orientation and must be verified on the assembled unit.

`fact-c470643-adc-design`	10 kOhm +/-30% gives 7-13 kOhm; worst-case divider Thevenin resistance 3.25 kOhm plus R27 100 Ohm = 3.35 kOhm before the parallel 100 kOhm bias. R22 loads the transfer curve and biases an open wiper low; nominal R22 x C22 decay time is 10 ms.	`NONE`	Engineering calculation from selected values; open wiper is not a guaranteed fault detector. ADC acquisition/reference/errata and endpoint calibration remain prototype gates.

Interactions

Behaviour that is not a property of this part alone. Each interaction names the records it spans, the conditions it holds under, and how far it has been confirmed. An interaction that spans several parts appears on every one of their pages, under the same identifier, because it is equally a fact about each.

Records involved: rec-c470643 (this record)
Conditions: Generated connectivity does not establish physical fit, contact behavior or installed firmware; validate the assembled prototype.
Verdict: NEEDS BENCH

Cross-component rules

Rules that span several parts at once and are published in full on the integration page. Each rule's verdict below is that rule's own — it is a statement about the cross-component question, not about this part — and the exact wording of what the rule refuses to conclude is published with the rule itself.

Legend

What the recorded terms on this page mean, in ordinary words. The exact terms above are the ones that count; these descriptions explain them and never replace them.

Verdict

Recorded term	What it means
`CONFIRMED - distributor identity only`	A distributor listing confirms which part this is, and nothing more. It carries no electrical, thermal or lifetime authority.
`NOT APPLICABLE`	The parameter does not apply to this part as it is used here.
`PASS - primary-source confirmed`	Confirmed against the manufacturer's own document for this exact part.

Provenance

Recorded term	What it means
`DISTRIBUTOR-IDENTITY`	Taken from a distributor listing. Identity information only.
`PRIMARY-SPEC`	Taken from the manufacturer's own specification document.
`PROJECT-CHOICE`	A decision made by this project. No vendor asserts it.

Fact class

Recorded term	What it means
`GUARANTEED_ELECTRICAL`	A parameter the manufacturer guarantees over the stated conditions, usually with minimum, typical and maximum values.
`PROJECT_STATE`	A value this project recorded about how the part is used here — a chosen operating point, a net assignment, or a derived figure. Not a manufacturer specification.
`RECOMMENDED_OPERATION`	The range the manufacturer intends the part to be used in. Always narrower than the absolute maximum.

Coverage status

Recorded term	What it means
`COVERED`	Every question this domain asks is answered by the facts listed against it.
`OPEN`	Unresolved. Open means the question has not been answered, not that the part is unsafe — the reason states what is missing.

Source availability

Recorded term	What it means
`AVAILABLE`	The document was retrieved and is on record.

Source authority

Recorded term	What it means
`DISTRIBUTOR_IDENTITY`	A distributor listing. Establishes which part this is, nothing more.
`MANUFACTURER_PRIMARY`	The manufacturer's own document for this exact part.
`PROJECT_GENERATOR`	A document this project generated, such as a schematic or netlist export.

Identity state

Recorded term	What it means
`VERIFIED`	The exact orderable part has been confirmed against a source.

Source state

Recorded term	What it means
`AVAILABLE`	At least one document backing this line was retrieved.

Unit

Recorded term	What it means
`NONE`	The value is not a physical quantity, so it carries no unit. Recorded as `NONE`.
