Part Review and Datasheet Update

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.

I reviewed the part against TE Connectivity’s official 2452796-1 customer drawing and updated the project’s Datasheet URL to the correct TE source. Main findings: the symbol/footprint are mostly consistent, but DETECTION_SWITCH should likely be SW/pin 7, all terminal pin types are still Unspecified, pin descriptions are missing, shell grounds use G1/G2/G3 instead of datasheet nos. 8–10, and explicit no-pattern/via keepouts are not represented.

2452796-1 Part Review
Source status
  • Project MPN: 2452796-1
  • Manufacturer: TE Connectivity
  • Existing project Datasheet URL before review: Mouser-hosted PDF ENG_CD_2390874_A1-3395045.pdf
  • Issue found: that PDF extraction identifies TE Connectivity 9-2390874-4, not 2452796-1.
  • Correct official source used for review: TE Connectivity customer drawing C-2452796 Rev C, NANO SIM CARD CONNECTOR — HINGE TYPE.
  • I updated the project Datasheet URL property to the official TE customer drawing URL.

Schematic symbol review
Matches
  • The symbol has 10 terminal elements, matching the 10 connector land pads/terminals in the TE drawing.
  • The six SIM contacts are present: VCC/C1, RST/C2, CLK/C3, GND/C5, VPP/C6, and I/O/C7.
  • Three shell/ground terminals are present: GROUND_1/G1, GROUND_2/G2, GROUND_3/G3.
  • A card-detect terminal is present.
Mismatches / issues
  1. Card-detect pin number mismatch
    • Datasheet: connector no. 7, pin name SW / S/W.
    • Project: DETECTION_SWITCH has Pin Number SW1.
    • Recommendation: use SW or connector number 7 consistently. The official drawing does not show SW1.
  2. Ground pad numbering differs from datasheet convention
    • Datasheet: connector nos. 8–10 are GND pads.
    • Project: ground shell pads are numbered G1, G2, G3.
    • This is understandable for readable pad labels, but if strict manufacturer numbering is desired, use 8, 9, 10 as Pin Number and keep the designators as GROUND_1/2/3 or GND_8/9/10.
  3. Pin Type properties are all Unspecified
    • Recommended mappings:
      • VCC/C1: Power In
      • RST/C2: Input
      • CLK/C3: Input
      • GND/C5: Ground
      • VPP/C6: Power In or Passive/Unspecified depending on intended SIM usage
      • I/O/C7: Bi-Directional
      • SW: Passive or Output/Unspecified depending on symbol convention for mechanical switch contact
      • Ground shell pads: Ground
  4. Pin Description properties are missing
    • Suggested short descriptions:
      • VCC: SIM supply
      • RST: SIM reset
      • CLK: SIM clock
      • GND: SIM ground
      • VPP: SIM programming voltage
      • I/O: SIM data I/O
      • DETECTION_SWITCH: Card detect switch
      • GROUND_1/2/3: Shell ground
Footprint review
Matches
  • Project footprint has 10 SMD pads, matching the official drawing.
  • SIM signal pad sizes match the drawing: 0.8 mm × 1.0 mm.
  • SIM signal pad x-order matches the recommended PCB layout: C1, C5, C2, C6, C3, C7.
  • Signal pad pitch is 1.27 mm, matching the drawing.
  • Side/shell pad size matches the drawing: 1.3 mm × 1.8 mm.
  • The footprint contains pads corresponding to SW and three ground/shell pads.
Mismatches / issues
  1. Coordinate Y orientation appears flipped relative to the KiCad source vs extracted Flux pad nodes
    • The embedded KiCad footprint lists signal pads at y = -6.75 mm and G1/SW1 at y = +6.25 mm.
    • Flux computed pad nodes show the same geometry with opposite Y signs for individual pad nodes.
    • This may be a coordinate-system import/display transform rather than a real footprint error, because the embedded KiCad asset itself looks consistent.
  2. Ground pad labels use G1/G2/G3, while TE drawing identifies connector nos. 8–10 as GND
    • Electrically acceptable if documented, but strict datasheet numbering would be clearer as 8/9/10 or GND_8/GND_9/GND_10.
  3. No explicit keepout/no-pattern regions were found as PCB keepout objects
    • TE drawing calls out cross-hatched areas as “NO PATTERN AND VIA HOLE IN THIS AREA.”
    • The current footprint has copper pads and silkscreen/fab geometry, but I did not see dedicated keepout zones represented in the layout node list.

DescriptionSIM Card Connectors, 4FF SIM Compatible Card, 7 Position, 7 Loaded Positions, Signal, -40 85 CMostly consistent with TE product-page summary, but the customer drawing itself shows 10 PCB land pads including shell/ground pads and switch terminal
Package or Case CodeNot setRecommend adding a package/footprint descriptor such as “Nano SIM hinge connector, SMD, 10-pad”
Part TypeNot set at project levelRecommend adding “Connector” if the part metadata supports it
Overall conclusion
The part is mostly consistent with the official TE Connectivity drawing: MPN/manufacturer match, symbol pin count matches the 10 connector land pads, and the footprint pad sizes/order match the recommended PCB layout. The main issues are metadata/detail issues: the previous datasheet link was for the wrong part, DETECTION_SWITCH uses SW1 instead of datasheet SW/connector no. 7, all symbol terminals have Pin Type = Unspecified, pin descriptions are missing, shell grounds use G1/G2/G3 instead of datasheet connector nos. 8–10, and the manufacturer keepout/no-pattern zones are not represented as explicit keepouts.
