**Wurth Elektronik** · WR-PHD pin header · 1x04, 2.54 mm pitch, THT vertical, gold

61300411121 is a 4-position, single-row, straight through-hole pin header from Wurth Elektronik's WR-PHD series: 0.64 mm square gold-plated copper-alloy pins on a black PA6T insulator, rated 3 A and 250 V AC. Each pin is 11.54 mm long: 6.0 mm mating length above a 2.54 mm insulator and a 3.0 mm solder tail. It mates with standard 2.54 mm female sockets and jumper housings for 0.64 mm square posts.

This page carries a KiCad symbol and footprint, a Fusion/EAGLE library, STEP and GLB 3D models, the datasheet, and the order numbers. The footprint follows the datasheet's recommended hole; the 3D model is **KiCad's generic 1x04 2.54 mm header model**, not Wurth Elektronik's own CAD (see 3D model below).

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Pin_1 | passive | Contact 1 of 4, the end the datasheet labels "1"; square pad 1 |
| 2 | Pin_2 | passive | Contact 2 of 4 |
| 3 | Pin_3 | passive | Contact 3 of 4 |
| 4 | Pin_4 | passive | Contact 4 of 4, the end the datasheet labels "End" |

The datasheet prints no signal names, only the end labels 1 and End (p.1). The header itself is symmetric; contact 1 is whichever end is soldered into the square pad. Pin_1 to Pin_4 is KiCad's connector naming, kept so the symbol matches KiCad's Conn_01x04.

## Footprint

![Footprint beside the datasheet's recommended hole pattern](/adom/61300411121/render/provenance/evidence/footprint-vs-datasheet.png)

The datasheet's hole-pattern view (p.1) is the WR-PHD **series** drawing: it shows ten holes from 1 to End with the length as the symbol pl. The value for this 4-pin part is in the Pattern Properties table: pl = 7.62 mm. The drawing also gives only the hole, 1.10 +-0.15 mm, not a copper pad. Read from the table, the pattern is four 1.10 mm holes at 2.54 mm; the 1.80 mm pad keeps the 0.35 mm annular ring of KiCad's own 2.54 mm header (1.0 mm drill, 1.7 mm pad). A nominal 0.64 mm square pin has a 0.905 mm diagonal, leaving about 0.2 mm in the hole. Every check is in `provenance/footprint-vs-datasheet.json`.

## 3D model

![The 3D model from six views](/adom/61300411121/render/provenance/evidence/model-views.png)

The model is KiCad's generic `PinHeader_1x04_P2.54mm_Vertical.step` (kicad StepUp, KiCad 10.0 library), unmodified. It was measured against every dimension the datasheet prints and all are inside the tolerances: pins 0.64 mm square at 2.54 mm, 11.54 mm long with 6.0 mm above and 3.0 mm below a 2.54 x 2.54 x 10.16 mm insulator (`provenance/model-vs-datasheet.json`). It is Z up, the insulator seated on z = 0 with the tails below, contact 1 on pad 1 at the origin, so the footprint binds it with no offset or rotation.

Wurth Elektronik's own STEP for this part was **not** obtained: we-online.com refuses automated downloads. Details the drawing does not dimension (the insulator's chamfers and notches) may differ from the real part. Anyone who downloads Wurth's model through a browser is welcome to compare and add it.

The part number on the etched copy (61300 / 411121 on the pin-1 end of the side wall) is a virtual identification mark drawn by Adom. The real header carries no printed part number.

`provenance/provenance.json` lists every file on this page with its sha256, source, authoring class (manufacturer original, KiCad library verbatim, KiCad library derived, Adom derived, Adom authored), tool and license. The tools that made and checked the files are in `provenance/tools/`.

The Adom parts factory declined to build this part on its own because its two readings of the land pattern disagreed; the series drawing above, with the part's value only in a table, is the likely reason. This page was built and checked by hand instead.
