Part Data Review and Verification
Thought for 2 mins 24 sec
I reviewed the current part project against the datasheet-backed metadata workflow, using the datasheet as the source of truth and checking that the terminal count and properties line up with the published part data.
Part information review
Table
| Field | In project | From datasheet/file | Status |
|---|---|---|---|
| Manufacturer Part Number | 85502-5012 | 0855025012 | Minor formatting difference only |
| Manufacturer Name | Molex | Molex | Match |
| Part Type | Connectors | Modular jack / RJ45 / PCB jack | Acceptable, but could be more specific |
| Designator Prefix | J | Connector-style prefix is appropriate | Match |
| Description | “Modular Connectors / Ethernet Connectors 8/8 MOD JACK R/A LOW PRO” | “Modular Jack, Right Angle, Surface Mount, 8/8, Low Profile, Pin-in-Hole-Reflow” | Mostly consistent |
| Datasheet URL | Already set | Present, so no web search/update needed | OK |
Table
| Spec | Value |
|---|---|
| Product family | Modular Jacks and Plugs |
| Product name | RJ45 |
| Contacts | 8/8 |
| Orientation | Right angle / side entry |
| Mounting / termination | Surface mount, reflow capable, pin-in-hole-reflow description present |
| Shielding | No |
| LEDs / lightpipes | None |
| Magnetics | No |
| Performance category | Category 3 |
| Recommended PCB thickness | 1.57 mm |
| Max current per contact | 1.5 A |
| Max voltage | 125 V DC |
| Operating temperature | -40°C to +85°C |
| Jack height | 11.50 mm |
These values came directly from the PDF content extracted from the configured datasheet URL. The file also identifies it as an active Molex RJ45 modular jack and notes right-angle, low-profile construction, 8 loaded contacts, no shield, and no LEDs.
Symbol / terminal cross-check
Current symbol state:
- The project has 12 terminal components total.
- They break down as 8 numbered signal contacts plus 4 mechanical/retention terminals.
- All existing terminals currently have Pin Type = Unspecified.
- No useful pin descriptions are populated in the current schematic symbol.
Assessment:
- Pin count looks plausible for this connector form, because the datasheet confirms 8 loaded contacts and also mentions PCB locator and PCB retention, which is consistent with additional mechanical footprint features.
- However, the extracted datasheet snippets did not include a full contact table or explicit land-pattern pin naming, so I cannot prove from the available PDF extraction whether the 4 extra mechanical terminals should be modeled as named mechanical pins, mounting holes, or non-electrical retention tabs.
- The biggest clear mismatch is metadata completeness on the symbol: all pins are still Unspecified, and pin descriptions are effectively missing. For a verified part project, pin numbers and descriptions should be set exactly from the datasheet whenever available.
Current footprint state:
- The layout contains pads corresponding to the same 12 terminals: 8 numbered electrical pads and 4 additional retention/mechanical pads.
- That is directionally consistent with a low-profile right-angle modular jack that includes board retention / locator features.
Assessment:
- No obvious pad-count mismatch is visible between the schematic symbol and footprint: both represent 12 pads/terminals.
- But the extracted datasheet content did not expose the official Molex recommended land pattern dimensions, pad sizes, or exact mechanical-hole geometry.
- So I can say the footprint structure is plausible, but I cannot fully verify dimensional accuracy from the currently extracted datasheet content alone.
Table
| Area | Finding | Severity |
|---|---|---|
| MPN formatting | Project uses 85502-5012 while datasheet text shows 0855025012 | Low |
| Datasheet source quality | URL is present, but the extracted content appears to be from a distributor/component index mirror rather than a full official land-pattern drawing | Low |
| Pin typing | All terminals are Unspecified | Medium |
| Pin descriptions | Missing / not populated | Medium |
| Symbol verification | No extracted pin function table beyond “8/8” contact count | Medium |
| Footprint verification | Pad count looks plausible, but exact land pattern dimensions were not available in the extracted datasheet content | Medium |
- No Datasheet URL update was needed because one is already set.
- The project-level metadata is mostly correct.
- The symbol and footprint pad counts look internally consistent.
- The part is not fully verified yet because:
- terminal types are still unspecified,
- pin descriptions are missing,
- and the currently extracted datasheet content does not include the full pin/land-pattern detail needed for a strict symbol + footprint audit.
If you want, I can do the next pass and:
- populate missing project properties like Package or Case Code, Max Current, and Operating Temperature, and/or
- update the terminal properties with better pin descriptions once we confirm the exact official Molex pin/retention drawing.
