I reviewed the part against its existing project metadata and the official Molex datasheet/drawing, using the datasheet as the source of truth and checking for exact pin-count alignment as recommended in the part-review workflow
Overall result
- Datasheet URL already exists, so no datasheet-property update was needed.
- MPN and manufacturer match the datasheet.
- Part Type = Connector and Designator Prefix = J are appropriate.
- The part is mostly structurally correct, but there are a few metadata and symbol-quality issues to fix.
Project properties found
| Property | Current value | Review |
|---|---|---|
| Manufacturer Part Number | 503182-1832 | Matches datasheet |
| Manufacturer Name | Molex | Matches datasheet |
| Part Type | Connector | Correct |
| Designator Prefix | J | Correct |
| Datasheet URL | https://www.molex.com/pdm_docs/sd/5031821832_sd.pdf | Already set |
| Package / Case Code | Missing | Should be added |
| Description | Memory Card Connectors Micro SD NormalUltra SM8CktEmbsTpPkg | Understandable but poor quality / not datasheet-style |
Key specs from the official datasheet/drawing
| Item | Datasheet value |
|---|---|
| Part | Molex 503182-1832 |
| Function | microSD card connector |
| Loaded circuits | 8 |
| Mounting style | Surface mount |
| Pitch | 1.10 mm |
| Height | 1.45 mm |
| Card detect switch | Yes |
| Shielded | Yes |
| Current rating | 0.5 A per contact max |
| Voltage rating | 10 V max |
| Operating temperature | -25 C to +85 C |
| Durability | 10,000 cycles |
| Contact resistance | 100 mOhm max |
| Insulation resistance | 1000 MOhm min |
The symbol has the expected 8 signal contacts and their names align with the datasheet pinout:
- pin 1 = DATA2
- pin 2 = CD/DAT3
- pin 3 = CMD
- pin 4 = VDD
- pin 5 = CLK
- pin 6 = VSS
- pin 7 = DAT0
- pin 8 = DAT1
So the electrical pin naming and numbering are correct.
Issues found
| Area | Finding | Severity |
|---|---|---|
| Pin descriptions | No explicit Pin Description property is set on the terminals | Medium |
| Pin types | All terminals are set to Unspecified | Medium |
| Naming consistency | Symbol uses DATA2 while datasheet uses DATA 2; functionally okay, but not exact text match | Low |
| Mechanical pads | There are 7 extra pads labeled MP1-MP7, but they are not described as shield, detect, ground, or mechanical hold-down pads | Medium |
| Detect switch clarity | Datasheet indicates a card detect switch, but the current symbol/terminal naming does not clearly identify which extra pads belong to the switch | High |
- The footprint contains 15 pads total:
- 8 signal pads
- 7 additional pads
- That overall structure is plausible for this connector family because the datasheet indicates:
- 8 loaded circuits
- shield / retention features
- card detect switch
- keep-out / solder-prohibition / switch areas in the recommended PCB layout
Issues / flags
| Area | Finding | Severity |
|---|---|---|
| Package metadata | No Package / Case Code property is present | Medium |
| Footprint semantic labeling | Extra pads are only labeled MP1-MP7, so the footprint does not clearly document which are shell, ground, or switch contacts | Medium |
| Recommended-pattern verification | I could confirm the pad-count structure, but not fully verify pad geometry/dimensions from the current project data alone | Low |
| Description of special areas | No project metadata captures important footprint notes like switch keep-out area, solder prohibition area, or stencil notes | Low |
- Add Package / Case Code such as:
- microSD SMT, 1.45 mm height, 1.10 mm pitch
- Improve the description to something like:
- microSD card connector, 8 circuits, SMT, push-push, 1.45 mm height, with card-detect switch
- Add Pin Description to all 8 signal pins.
- Set Pin Type appropriately:
- DATA/CMD/CLK pins: likely Bi-Directional or Unspecified if you want to stay conservative for SD multifunction behavior
- VDD: Power In
- VSS: Ground
- Classify MP1-MP7 explicitly as:
- shield / shell / hold-down / switch pads as applicable from the drawing
- Identify which of MP1-MP7 are:
- mechanical retention tabs
- shield/ground tabs
- card-detect switch pads
- Add that meaning to each pad's description so the part is easier to reuse correctly.
- MPN, manufacturer, connector type, datasheet URL
- 8-pin electrical interface naming/numbering
- Footprint pad-count structure is believable for the part
- No Package / Case Code property
- No pin descriptions
- All pin types left as Unspecified
- Mechanical/detect/shield pads are not semantically identified
- Project description should be cleaned up
If you want, I can turn this into a concrete fix list for the part and update the missing metadata and terminal properties next.
