Single- and dual-row THT
The reviewed straight and right-angle through-hole versions use PA6T bodies with gold-flash phosphor-bronze contacts. Check the chosen row layout, mating-post length and PCB footprint.

Specifications and configuration scope
Use these drawing values for initial selection. Check the row layout, mounting and dimensions for the exact configuration before ordering; matching pitch alone does not establish mating compatibility.
| Parameter | Drawing value / scope |
|---|---|
| Series | PH127 |
| Pitch | 1.27 mm |
| Current rating | 1 A AC/DC |
| Voltage rating | 250 V AC/DC |
| Withstanding voltage | 500 V AC for 1 minute |
| Temperature range | −25°C to +85°C |
| Insulation resistance | 500 MΩ minimum |
| Contact resistance | 20 mΩ maximum |
| Single-row drawing tables | 2–50 positions; select the applicable configuration table |
| Dual-row drawing tables | 2 × 2 through 2 × 50 positions; not every mounting or height combination |
Configuration selection
Choose the PH127 construction
The configurations below follow the supplied series drawings. They are not interchangeable options for every part. Include the required construction in your request.
Dual-row stacked SMT
The drawing with two insulating spacers specifies an LCP body and gold-flash phosphor-bronze contacts. Confirm both spacer dimensions and the required distance between them.
Dual-row SMT
Other straight dual-row SMT drawings specify PA6T with gold-flash phosphor-bronze contacts, including a locating-post version. Body, tail and locating dimensions must follow the selected drawing.

What to include in your request
A dimensioned drawing, BOM or marked-up sketch helps identify the required header configuration.
- Specify the number of rows and positions per row, not just the total contact count.
- Provide the mating-post length, solder-tail length, insulator height and any spacing between insulators.
- Identify THT or SMT mounting, mating direction and the PCB hole or pad layout. Matching pitch alone is insufficient.
- For PH127 SMT, identify the documented dual-row construction; do not infer single-row SMT availability from the THT tables.
- Include the sample quantity and expected production quantity. Ask for the matching drawing and any CAD or STEP file you need for review.
