Straight and right-angle THT
Single- and dual-row THT drawings use gold-flash brass contacts. Bodies are PA6T or PBT depending on the version; straight single-row uses PBT and the reviewed straight dual-row uses PA6T.

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 | PH254 |
| Pitch | 2.54 mm |
| Current rating | 3 A AC/DC |
| Voltage rating | 250 V AC/DC |
| Withstanding voltage | 1,500 V AC for 1 minute |
| Temperature range | −25°C to +85°C |
| Insulation resistance | 1,000 MΩ minimum |
| Contact resistance | 20 mΩ maximum |
| Single-row drawing tables | 2–40 positions; select the applicable configuration table |
| Dual-row drawing tables | 2 × 2 through 2 × 40 positions; not every mounting or height combination |
Configuration selection
Choose the PH254 construction
The configurations below follow the supplied series drawings. They are not interchangeable options for every part. Include the required construction in your request.
Stacked through-hole headers
The drawings include straight single- and dual-row stacked THT versions. Single-row uses PBT; dual-row lists PBT or PA6T. Confirm the insulator spacing and mating-post length for the intended board separation.
Configuration-specific SMT
The verified right-angle single-row SMT and straight dual-row SMT drawings specify PA6T bodies with gold-flash brass contacts. Do not infer every row-and-angle combination from these two constructions.

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 SMT, identify right-angle single-row or straight dual-row construction and provide the matching footprint.
- Include the sample quantity and expected production quantity. Ask for the matching drawing and any CAD or STEP file you need for review.
