Part Metadata 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.
Thought for 4 sec
I’ll inspect the part metadata, find and attach the official datasheet if missing, then compare symbol pins, footprint, and descriptions against the datasheet.
Worked for 3 mins 4 sec
Reviewed the JST BM06B-GHS-TBT part metadata, symbol, footprint, and datasheet. The datasheet URL was already set, so I left it unchanged; no clearly indexed official JST direct PDF was found via web search.
Key flags: symbol pin descriptions are blank, and the footprint signal pads are 0.6 × 1.7 mm while the datasheet extraction indicates 0.6 × 1.35 mm recommended pads. Full findings are in the project document:

BM06B-GHS-TBT Part Review
Reviewed project metadata
- Project / part name: BM06B-GHS-TBT
- Published part UID: de2bfc6e-2870-41c5-9622-a6b65b3d8aa7
- Manufacturer: JST
- Manufacturer Part Number: BM06B-GHS-TBT(LF)(SN)(N)
- Description: CONN HEADER GH TOP 6POS 1.25MM
- Part Type: Connectors
- Designator Prefix: J
- Datasheet URL: 6063c7632738cca6577bca80e6737cfcdd7254f921183d6963ceeb32649508f4.pdf
The Datasheet URL was already populated. I searched the web for an official JST-hosted direct PDF; common results point to distributor/mirror-hosted JST GH-series datasheets (Mouser, LCSC, DigiKey, AllDataSheet, Datasheet.Online), but no clearly indexed direct official JST PDF URL was found. I therefore did not overwrite the existing datasheet URL.
Key datasheet specs
- Series: JST GH connector, 1.25 mm pitch, disconnectable crimp-style wire-to-board connector.
- Header style: BM...GHS... SMT top-entry header.
- Circuits / signal pins: 6.
- Pitch: 1.25 mm.
- Electrical rating: 1.0 A AC/DC using AWG 26 wire; 50 V AC/DC.
- Temperature range: -40 °C to +105 °C.
- Contact resistance: 30 mΩ max initial, 50 mΩ max after test.
- Insulation resistance: 100 MΩ min.
- Withstanding voltage: 500 VAC for 1 minute.
- Applicable wire: AWG 30 to AWG 26, 0.05 to 0.13 mm²; insulation OD 0.76 to 1.0 mm.
- Matching housing: GHR-06V-S.
- Crimp contact: SSHL-002T-P0.2.
- Header contact/reinforcement material: copper alloy, tin plated.
- Header housing: heat-resistant PA, natural/ivory.
- 6-circuit dimensions: A = 6.25 mm, B = 10.75 mm.
- Recommended PCB footprint, top-entry type: signal pad pitch 1.25 ±0.05 mm; signal pad width 0.6 ±0.05 mm; signal pad length 1.35 ±0.1 mm; reinforcement pads 1.0 ±0.1 mm × 2.8 ±0.1 mm.
Schematic symbol cross-check
Observed symbol terminals:
Table
| Symbol terminal | Pin Number property | Pin Type | Pin description |
|---|---|---|---|
| 1 | 1 | Unspecified | Not set |
| 2 | 2 | Unspecified | Not set |
| 3 | 3 | Unspecified | Not set |
| 4 | 4 | Unspecified | Not set |
| 5 | 5 | Unspecified | Not set |
| 6 | 6 | Unspecified | Not set |
Result: The symbol has the correct 6 electrical terminals and pin numbers 1–6. Since this is a passive connector with no predefined signal functions,
Unspecified pin type is acceptable. Pin descriptions are not populated; adding generic descriptions such as Contact 1 through Contact 6 would improve clarity but is not an electrical mismatch.Footprint cross-check
Observed KiCad footprint data:
- SMD signal pads: 1–6.
- Signal pad coordinates: x = +3.125, +1.875, +0.625, -0.625, -1.875, -3.125 mm; y = -0.3 mm.
- Signal pad pitch: 1.25 mm.
- Signal pad size: 0.6 mm × 1.7 mm.
- Retention / reinforcement pads: pads 7 and 8, each 1.0 mm × 2.8 mm, at x = ±4.975 mm, y = 3.05 mm.
- Fab outline: 10.75 mm × 4.25 mm.
Result: The footprint matches the datasheet on pin count, 1.25 mm pitch, 0.6 mm signal pad width, 1.0 mm × 2.8 mm reinforcement pads, and 10.75 mm body/reference width. The signal pad length is 1.7 mm in the footprint, while the datasheet extraction reports 1.35 ±0.1 mm. This may be an intentional land-pattern extension or may reflect a different interpretation of the drawing; it should be reviewed against the original dimensional figure before production.
Mismatches / issues flagged
- Datasheet URL is not an official JST direct URL; it is a stored uploaded PDF. Web search did not reveal a clearly indexed direct official JST PDF, so it was left unchanged.
- Symbol pin descriptions are blank. This is not electrically wrong for a generic connector, but should ideally be filled as
Contact 1–Contact 6or assigned user-specific signal names in a design instance. - Footprint signal pad length is 1.7 mm versus datasheet-extracted recommended length of 1.35 ±0.1 mm. Width, pitch, retention pads, and outline match. Verify the original JST land-pattern drawing before release.
- Footprint has mechanical pads 7 and 8, while the schematic has only 6 electrical terminals. That is expected for this connector because pads 7/8 are reinforcement tabs, not electrical contacts.
Overall assessment
The part is broadly consistent with the JST BM06B-GHS-TBT(LF)(SN)(N) datasheet: metadata, pin count, top-entry SMT connector style, pitch, signal pad ordering, and reinforcement pads all align. The only substantive item to verify is the footprint signal pad length before manufacturing.
