Part Datasheet Audit
Thought for 9 sec
I’ll audit the part metadata, locate the official manufacturer datasheet if needed, update the Datasheet property, then compare the symbol, footprint, and pin definitions against the source.
Worked for 12 sec
I found the part-project terminals; I’m now checking project metadata and the exact pad geometry before comparing them with Panasonic’s RN-series documentation.

ARN10A12Z Part Datasheet Audit

Audit complete. The 15-terminal pin map and footprint geometry match Panasonic’s ARN10A12Z datasheet; the existing Datasheet URL was valid, so no update was needed. Main flags are unspecified pin types/descriptions, overly generic RF-relay metadata, and a footprint asset named for the ARN12A12 variant despite compatible geometry.

ARN10A12Z Part Datasheet Audit
Scope and source
Reviewed project metadata, all 15 schematic terminals, the symbol arrangement, the imported KiCad footprint, pad geometry, and the 3D-model reference. Cross-checked against Panasonic RN Relays catalog ASCTB71E 202407 and Panasonic's ARN10A12 product page.
- MPN: ARN10A12Z
- Manufacturer: Panasonic Industry
- Existing Datasheet URL: present and readable; no property update was required.
- Official product page: https://industry.panasonic.com/global/en/products/control/relay/device-hi/number/arn10a12
- Current Panasonic catalog copy used for cross-check: https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/8810/mech_eng_rn.pdf
Identity and ordering-code check
ARN10A12Z decodes correctly as:- RN microwave relay series
1: 1 Form C standard contacts0: single-side-stable operationA: surface-mount terminals12: 12 VDC rated coilZ: tape-and-reel, picked from the pin-13 side
The project MPN, manufacturer, mount style, and description's 1 Form C / single-side-stable claims are consistent. The description calls it a signal relay, but Panasonic classifies and markets it specifically as a 50-ohm microwave/RF relay; this is an imprecision rather than a wrong MPN.

Pin and symbol cross-check
The part correctly contains 15 physical terminals, numbered 1-16 with pin 11 omitted, exactly as shown by Panasonic.
Table
| Pin | Project label | Datasheet function | Result |
|---|---|---|---|
| 1 | COIL_+ | Polarized coil + | Match |
| 2 | GND_1 | RF ground | Match |
| 3 | COM | Common RF contact | Match |
| 4 | GND_2 | RF ground | Match |
| 5 | COIL_- | Polarized coil - | Match |
| 6 | GND_3 | RF ground | Match |
| 7 | N.O. | Normally-open RF contact | Match |
| 8 | GND_4 | RF ground | Match |
| 9 | NOT_CONNECTED_1 | Not connected for single-side-stable type | Match |
| 10 | GND_5 | RF ground | Match |
| 11 | absent | No terminal | Match |
| 12 | GND_6 | RF ground | Match |
| 13 | NOT_CONNECTED_2 | Not connected for single-side-stable type | Match |
| 14 | GND_7 | RF ground | Match |
| 15 | N.C. | Normally-closed RF contact | Match |
| 16 | GND_8 | RF ground | Match |
The schematic terminal numbering and left/right grouping are consistent with the datasheet top-view diagram. The pin-1 direction indicator is also present in the footprint.
Footprint cross-check
The imported footprint geometry agrees with Panasonic's recommended top-view land pattern:
- Body outline: 14.6 x 9.6 mm
- Main signal-pad centers: 8.89 mm spacing where specified
- Standard pads: 1.6 x 2.9 mm
- Four narrow pads: 0.8 x 3.17 mm
- Side pad center positions and overall pattern extents are consistent with the drawing
- Pads are numbered 1-10 and 12-16; no pad 11, as required
No functional pad-number, pad-count, or obvious land-pattern mismatch was found.
Mismatches and quality flags
- Pin metadata incomplete: every terminal has
Pin Type: Unspecified, and no usefulPin Descriptionis populated. Recommended types/descriptions are coil power/passive, RF contact passive, RF ground power/passive, and no-connect for pins 9 and 13. - Description is too generic: “Surface Mount Signal Relay” omits the defining microwave/RF, 50-ohm, and 8-GHz characteristics.
- Part Type is overly broad:
Electromechanical Componentsis valid but less useful than Relay / RF Relay classification. - Footprint asset naming mismatch: the embedded footprint is named
ARN12A12, which denotes the 2-coil-latching variant, while this part is ARN10A12Z. The package/land geometry is shared and appears correct, so this is a naming/provenance issue rather than a manufacturing mismatch. - Datasheet link provenance: a Datasheet URL is already set to an uploaded PDF copy rather than a Panasonic-domain URL. It is readable and contains the current Panasonic catalog, so it was not replaced under the user's conditional instruction.
- Symbol semantics: pins 9 and 13 are labeled
NOT_CONNECTED, which is correct for this operating variant, but explicit no-connect pin typing would improve ERC behavior.
Overall assessment
The MPN and core package/pin implementation are consistent with the Panasonic datasheet, and the footprint appears manufacturable. The main deficiencies are metadata quality and naming clarity, not electrical pin mapping or land-pattern geometry.
