FIELD REFERENCE / EXACT COMPACT COAX

Keep the part number.
Keep the viewpoint.

SMB and DIN 1.0/2.3 move from family recognition to named component studies. A familiar outline still does not settle the board layout, mating part or operating limit.

01 / IDENTITY

A full part number.

142144 and 282100-75 are the two illustrated component identities. The separately listed 282100 does not inherit the -75 image.

02 / VIEWPOINT

A side, not a pinout.

The SMB board-side study faces toward its PCB terminals. It is not a view into the mating interface.

03 / SOURCE

A conflict, not a verdict.

For 282100-75, the product page and linked drawing report different frequency limits. Both values remain visible.

TWO EXACT COMPONENTS / THREE PHYSICAL VIEWS

Inspect view & provenance

SMB gains its first registered specimen and first source-observed physical view. DIN gains an exact 282100-75 study alongside its retained family illustration. The two SMB viewpoints count as two assets, not two connector forms. No scale, thread specification, terminal map or manufacturing footprint is supplied. All new views are supplementary.

What this round does not close

The exact 50-ohm 282100 drawing was not visually inspected; the 75-ohm component image is not its substitute. Earlier compact-coax family-level rating conflicts remain in their original references. No installation instruction, equipment-specific match, engineering dimension or independent review is implied.

Eight canonical claims and five source observations deepen two existing connector forms. Three exact-part exterior studies and one concept are original qualitative vectors. Manufacturer originals are not redistributed. Review the measured gaps →
