Electrical characteristics
| Parameter | Value |
|---|---|
| Voltage rating | 300 V AC |
| Current rating | 8.0 A at 3.50 mm pitch |
| Operating temperature | -40°C to +105°C |
| Contact resistance | 8 mΩ maximum [initial] |
| Insulation resistance | 500 VDC min.; 500 Megohms max |
| Dielectric withstanding voltage | 2.5 kV, 60 Hz for 1 minute |
| Temperature rise | +30°C maximum per stated test |
| Surge voltage | 4.0 kV, 5 times |
Absolute maximum ratings
| Result | Note |
|---|---|
| No explicit “Absolute Maximum Ratings” table found | This document does not present a separate abs-max section |
Recommended operating conditions
| Result | Note |
|---|---|
| No separate “Recommended Operating Conditions” table found | The usable operating limits provided are 300 V AC, 8.0 A, and -40°C to +105°C |
Pin descriptions
| Result | Note |
|---|---|
| No explicit per-pin functional descriptions found | This is consistent with a simple 4-position passive header; pins are positional only: 1-4 |
Package / mechanical dimensions
| Parameter | Value |
|---|---|
| Connector style | Vertical PCB header |
| Pitch | 3.50 mm |
| Circuit count | 4 |
| A dimension | 15.40 mm |
| B dimension | 10.50 mm |
| PCB hole diameter | Ø 1.30 mm typ. |
Special features
| Result | Note |
|---|---|
| No dedicated “special features” section found | The document is primarily dimensional/specification-oriented |
4) Symbol and footprint cross-check
Footprint vs datasheet
| Check | Result | Details |
|---|---|---|
| Circuit count | Pass | Footprint asset shows 4 pads, matching 4 circuits |
| Pitch | Pass | Footprint uses 3.500001 mm spacing, matching datasheet 3.50 mm |
| End-to-end pad span | Pass | Pad 1 to Pad 4 span is 10.500002 mm, matching datasheet dimension B = 10.50 mm |
| Drill diameter | Pass | Footprint drill 1.2954 mm closely matches datasheet Ø 1.30 mm typ. |
| Mounting style | Pass | Footprint is through-hole, matching the connector drawing |
Symbol vs datasheet
| Check | Result | Risk |
|---|---|---|
| Pin count representation | Fail / suspicious | The schematic currently shows duplicated 1, 2, 3, 4 terminals across two sub-symbol groups, which does not match a normal single 4-circuit part representation |
| Pin typing | Fail | All pins are Unspecified; for a passive connector they should be Passive |
| BOM abstraction | Fail / suspicious | BOM view reports 8 Terminal entries rather than one coherent 4-circuit connector representation |
Flagged issues
| Severity | Issue | Why it matters |
|---|---|---|
| High | Symbol appears duplicated | Could create incorrect connectivity, confusing pin mapping, and a misleading published part |
| Medium | Pin electrical types are unspecified | Can weaken ERC usefulness and make downstream integration less reliable |
| Low | Metadata is incomplete in a connector-specific way | No richer package code / structured pin descriptions, though this is less critical than the symbol issue |
- The footprint looks correct for the Molex 395011004.
- The symbol looks problematic: it appears to represent the same 4 pins twice, which is the main issue that could cause design confusion or incorrect use of the published part.
