Description
Standard 10-pin (2x5) shrouded male IDC box header with 2.54mm (0.1”) pitch. The 4-wall shrouded housing provides mechanical protection, polarization, and alignment for mating IDC ribbon cable connectors — preventing incorrect insertion.
These are the PCB-side connector for Eurorack modular synthesizer power distribution, where the 10-pin format carries ±12V and GND rails. They’re also widely used for AVR ISP programming headers, generic ribbon cable interfaces, and any board-to-cable application needing a keyed, strain-relieved connection.

Pin Descriptions (2x5 Through-Hole, Eurorack Power Standard)
| Pin | Name | Function |
|---|---|---|
| 1 | -12V | Negative 12V supply (red stripe side) |
| 2 | GND | Ground |
| 3 | GND | Ground |
| 4 | GND | Ground |
| 5 | GND | Ground |
| 6 | GND | Ground |
| 7 | GND | Ground |
| 8 | GND | Ground |
| 9 | +12V | Positive 12V supply |
| 10 | +12V | Positive 12V supply |
Note: Pinout above is the Doepfer/Eurorack power standard. For ISP or other applications, pin assignments differ — always verify with your specific application’s schematic. Pin 1 is on the side of the polarizing key notch.
Applications
- Eurorack modular synthesizer module power connectors (PCB side)
- AVR 10-pin ISP programming headers
- JTAG debug interfaces
- Generic ribbon cable board-to-cable connections
- Development board expansion headers
- Test jig interfaces

GND ──── Pin 2–8 ────────── GND (multiple)
+12V ──── Pin 9–10 ────────── +12V

Pin 3: NC Pin 4: GND
Pin 5: RST Pin 6: GND
Pin 7: SCK Pin 8: GND
Pin 9: MISO Pin 10: GND
Technical Notes
- The red stripe on IDC ribbon cable always goes to Pin 1 — for Eurorack this means -12V. Double-check before powering a module.
- Housing notch/key is on the Pin 1 side — it physically prevents reversed insertion with a keyed cable connector.
- Add a ferrite bead on the +12V and -12V lines on module PCBs to reduce bus noise.
- These are unshrouded on the cable side — use a matching 10-pin IDC female ribbon connector to complete the assembly.

Notes
Generic part; On Shore Technology 302-S101 and Würth Elektronik 61201021621 are functionally identical drop-in equivalents with the same footprint. All share standard 2.54mm pitch and 4-wall shrouding. The 16-pin Eurorack variant (2x8) is in Cabinet-3, Bin-55.
