Part Audit Review
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 9 sec
I’ll audit the part metadata, source the official manufacturer documentation if needed, then verify the symbol, footprint, and pin mapping and correct only the Datasheet property if it is missing.

Audit complete. The official TE Connectivity datasheet URL was already set, so no property update was needed; the five-pad/two-locating-hole footprint broadly matches the drawing, but pin descriptions, package metadata, and definitive relay-contact numbering are missing, with a minor 3.5 mm vs. ~3.6 mm pad-land discrepancy.

Identification and metadata
Table
| Field | Current value | Assessment |
|---|---|---|
| Manufacturer part number | 1393310-3 | Matches TE Connectivity internal number for VCF4-1000 |
| Manufacturer | TE Connectivity | Matches official source |
| Description | VCF4-1000=FROM SEC RELAY SOCKET 5 POS THROUGH HOLE | Functionally correct but contains the opaque manufacturer shorthand FROM SEC; clearer wording would be “VCF4-1000 5-position through-hole PCB socket for Mini ISO relays” |
| Part type | Connectors / Other | Acceptable; “Relay Socket” would be more specific if available |
| Mount | Through Hole | Correct |
| Pin/terminal count | 5 | Correct for the five electrical relay contacts |
| Package | No explicit package/case property found; footprint asset is 13933103.kicad_mod | Package metadata is incomplete, although the footprint is present |
| Datasheet URL | Official TE Connectivity document-delivery URL for VCF4-X0000-A001 | Already set; no update was required |
| Lifecycle | Active on the official TE product page | Consistent |
Official documentation reviewed
- TE Connectivity product page: https://www.te.com/en/product-1393310-3.html
- TE Connectivity datasheet: https://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv&DocNm=VCF4-X0000-A001&DocType=Data+Sheet&DocLang=English&PartCntxt=1393310-3&DocFormat=pdf
The official product page identifies VCF4-1000, TE internal number 1393310-3, as active. The family/accessory datasheet identifies it as a PC board socket for Mini ISO relays, with five electrical holes and two locating pins.
Key mechanical specifications
- Socket body envelope shown: approximately 24.0 mm x 26.5 mm.
- Five electrical PCB holes, nominal drawing diameter approximately 2.3 mm.
- Two non-electrical locating holes/pins, nominal diameter approximately 2.1 mm.
- Key contact-location dimensions shown include approximately 9.5 mm, 8.4/8.445 mm, 17.9 mm, and locating-pin offsets around 2.0 mm / 16.0 mm and 6.5 mm.
- Manufacturer assembly note: solder the socket with the relay already inserted to keep insertion force away from the PCB.
The accessory datasheet does not specify independent socket voltage/current ratings; usable electrical ratings are governed by the compatible relay/contact system and application.
Symbol review
- The symbol has five terminals numbered 1 through 5, matching the electrical contact count.
- It is drawn as five generic terminals rather than a relay-socket outline. This is electrically usable, but the symbol does not communicate the Mini ISO relay contact arrangement.
- All pins use Pin Type: Unspecified and have no meaningful pin names or descriptions.
- The reviewed TE accessory datasheet does not provide a definitive numbered contact-function table, so functions such as coil, common, normally open, and normally closed cannot be safely assigned from this document alone.
- No electrical-to-mechanical pin-numbering mismatch could be proven from the available official datasheet, but the mapping remains unverified.
Footprint review
The footprint contains five plated through-hole pads and two non-plated locating holes:
Table
| Feature | Footprint | Datasheet comparison |
|---|---|---|
| Electrical pads | 5 | Matches |
| Locating holes | 2 NPTH | Matches |
| Electrical drill | 2.3368 mm | Consistent with the nominal 2.3 mm drawing value; small difference is plausibly source precision/tolerance |
| Electrical pad diameter | 3.5 mm | Drawing appears to show about 3.6 mm land diameter; footprint is about 0.1 mm smaller |
| Locating drill | 2.1082 mm | Matches nominal 2.1 mm |
| Pad 1 position | (0, 0) mm | Datum-compatible |
| Pad 2 position | (9.500, 8.445) mm | Matches drawing dimensions |
| Pad 3 position | (17.907, 0) mm | Matches approximately 17.9 mm |
| Pad 4 position | (9.500, -8.445) mm | Matches drawing dimensions |
| Pad 5 position | (9.906, 0) mm | Geometrically plausible, but exact association with the manufacturer’s contact numbering is not confirmed by the available datasheet text |
| Locating holes | (2.007, -6.5) and (16.002, 6.5) mm in source coordinates | Matches the nominal 2.0/16.0 mm and 6.5 mm offsets, allowing for footprint-axis orientation |
The body/silkscreen geometry broadly follows the manufacturer outline. The courtyard is larger than the nominal body, which is appropriate for assembly clearance.
Mismatches and risks
- Pin descriptions are missing: pins 1–5 are unnamed, unspecified, and lack functional descriptions.
- Contact-function mapping is not verified: the official accessory datasheet reviewed does not establish which numbered socket hole corresponds to relay terminals 30, 85, 86, 87, or 87a.
- Package metadata is incomplete: no explicit Package or Package/Case Code property is present even though a footprint exists.
- Description quality: current text includes manufacturer shorthand and could be clearer.
- Minor pad-land discrepancy: 3.5 mm footprint pads appear about 0.1 mm smaller than the approximately 3.6 mm drawing value. The 2.3368 mm drill leaves about 0.58 mm annular ring per side, so it remains physically plausible, but the land dimension should be confirmed against a dimensioned product drawing/tolerance source before high-volume release.
- Footprint numbering risk: geometry is a close match, but pad-number orientation cannot be fully validated without an official pin-numbered bottom-view drawing or the exact mating relay drawing.
Recommended corrections
- Keep the existing Datasheet URL; it is official and valid.
- Add an explicit package description such as TE VCF4-1000, 5-position THT relay socket, 2 locating pins.
- Replace the description with clear user-facing wording while retaining VCF4-1000 and 1393310-3.
- Obtain the exact mating Mini ISO relay/contact-number drawing before adding functional pin names or declaring the pad-number mapping verified.
- Consider increasing electrical pad diameter from 3.5 mm to the documented nominal land diameter only after confirming the drawing’s tolerance and whether the 3.6 mm callout is the recommended PCB land rather than a product feature.
