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).++## Key specifications++| Parameter | Value | Source |+|---|---|---|+| Positions | 4, single row | datasheet p.1 |+| Pitch | 2.54 +-0.05 mm | p.1 |+| Pin | 0.64 +-0.15 mm square | p.1 |+| Pin length | 11.54 +-0.2 mm total: 6.0 mating, 2.54 insulator, 3.0 tail | p.1 |+| Insulator | 10.16 +-0.35 x 2.54 +-0.15 mm, 2.54 +-0.15 mm high | p.1 |+| Recommended hole | 1.10 +-0.15 mm, pl (pin 1 to End) 7.62 +-0.1 mm | p.1 |+| Rated current | 3 A | p.2 |+| Working voltage | 250 V AC | p.2 |+| Withstanding voltage | 500 V AC, 1 min | p.2 |+| Contact resistance | 20 mOhm max | p.2 |+| Insulation resistance | 1000 MOhm min | p.2 |+| Insulator material | PA6T, black, UL94 V-0 | p.2 |+| Contacts | copper alloy, gold plated, stamped | p.2 |+| Operating temperature | -40 to +105 C | p.2 |+| Durability | 25 mating cycles | p.2 |+| Approvals | RoHS, REACH, UL E323964 | p.2 |+| Soldering | wave, peak 250 to 260 C, 10 s max (EN 61760-1) | p.4 |+| Packaging | bag of 1000 | p.3 |++## 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.++## Ordering++| Distributor | Part number | Stock (2026-11-10) | Price |+|---|---|---|---|+| Mouser | [710-61300411121](https://www.mouser.com/ProductDetail/Wurth-Elektronik/61300411121?qs=PhR8RmCirEYQcLLqXD8rAA%3D%3D) | 115,305 | $0.19 (1), $0.102 (100) |+| DigiKey | [732-5317-ND](https://www.digikey.com/en/products/detail/w%C3%BCrth-elektronik/61300411121/4846827) | 120,886 | $0.18 (1), $0.1047 (100) |+| JLCPCB / LCSC | [C5184785](https://jlcpcb.com/parts/componentSearch?searchTxt=C5184785) (extended part) | 1,544 | $0.2216 (1) |++Stock and prices are a snapshot from Adom Parts Search on the date shown.++## CAD files++| File | What it is |+|---|---|+| `61300411121.kicad_sym` | KiCad symbol: KiCad's Conn_01x04, renamed, with MPN, manufacturer, datasheet, Mouser, DigiKey, LCSC and wiki fields |+| `61300411121.kicad_mod` | KiCad footprint: KiCad's PinHeader_1x04_P2.54mm_Vertical with the datasheet's 1.10 mm hole and 1.80 mm pads; pad 1 square at the origin, pads along +Y |+| `61300411121.step` | 3D model the footprint binds (`${KIPRJMOD}/61300411121.step`): KiCad 10.0's PinHeader_1x04_P2.54mm_Vertical.step, byte-identical |+| `61300411121-etched.step`, `61300411121-etched.glb` | The same model with a virtual part-number mark on the insulator side wall |+| `61300411121.glb` | GLB of the plain model |+| `61300411121-hero.glb` | The wiki's 3D view: the etched model with the footprint's pad outlines, silkscreen, pin 1 dot and pin names as separate reference layers |+| `61300411121.lbr` | Fusion 360 / EAGLE library with MPN and order attributes |+| `61300411121.adom-lbr.json` | adom-lbr hub file, for Altium export (`adom-lbr export-altium`) |+| `docs/61300411121-datasheet.pdf` | Wurth Elektronik datasheet, rev 003.000 (2023-01-08) |++## 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++| Data | Source | Reference | Evidence |+|---|---|---|---|+| Identity, dimensions, hole pattern, end labels | Wurth Elektronik datasheet 61300411121 | rev 003.000, 2023-01-08, p.1 | [datasheet p.1](/adom/61300411121/render/docs/figures/61300411121-ds-p1.png) |+| Materials, electrical ratings, approvals | same datasheet | p.2 | [datasheet p.2](/adom/61300411121/render/docs/figures/61300411121-ds-p2.png) |+| Symbol | KiCad 10.0 Connector_Generic:Conn_01x04 | CC-BY-SA-4.0, KiCad library exception | `provenance/provenance.json` |+| Footprint | KiCad 10.0 PinHeader_1x04_P2.54mm_Vertical, hole and pad changed to the datasheet | datasheet p.1 | `provenance/footprint-vs-datasheet.json` |+| 3D model | KiCad 10.0 PinHeader_1x04_P2.54mm_Vertical.step, unmodified | sha256 a74079b8d06b... | `provenance/model-vs-datasheet.json` |+| Order numbers, stock, prices | Mouser, DigiKey, JLCPCB through Adom Parts Search | 2026-11-10 | this page |++`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.
