## Notes

- This is not a full family table. It carries the rows of three maker sheets whose dimensions could be read: one Panduit butt splice (BSN14-C), the six JST bullet-terminal lines (SGM / SGF in -4 and -5 sizes) and one TE PIDG spade (12-10 AWG, #6 / M3.5 stud). Ring terminals have their own page (ring-tongue-terminals-by-stud-and-wire) and FASTON blades are on faston-quick-connect-tabs.
- JST's sheet labels the dimensions only as 'D (dia.)', 'L' and 'S' in its diagrams; the text read does not say what L and S measure, so they are shown by those letters. D is 3.5 to 3.96 mm on these lines. Other makers sell bullets as '4 mm' and '5 mm' bullet diameter (RS listings); whether JST's -4 / -5 suffix is that class is not stated in the sheet.
- TE's spade page lists the stud diameter and overall length but no tongue width or fork opening, so a spade or fork footprint cannot be drawn from it. Fork terminals, hook terminals and the other Panduit / TE sizes were not tabulated: the sheets read did not print them as readable tables.
- Wire ranges are the sheets' own AWG and mm2 figures. The Panduit sheet lists the 16-14 AWG splice as blue.
- No file: none of the sheets read give a drawn profile as numbers. Maker CAD: Panduit and TE publish per-part CAD on their product pages; not linked because no page was read that carries the drawing.

## Questions

**How long is a 16-14 AWG butt splice?**

The Panduit BSN14-C is 1.15 in (29.2 mm) long and 0.2 in (5.1 mm) wide, strip length 9/32 in (7.1 mm).

**What diameter is a bullet terminal?**

JST's SGM / SGF bullet lines print D = 3.5 to 3.96 mm and L = 15.9 to 17.5 mm; the -4 and -5 suffixes are JST's size classes.

**How long is a PIDG spade for 12-10 AWG?**

TE 2-326859-1: overall length 27.81 mm for a #6 / M3.5 stud, tongue thickness 1.02 mm.
