Connector selection

Board-to-Board Connectors

Browse board interconnects, pin headers and female headers. Confirm the mating interface, PCB layout, installed height and mounting method.

LDZY B4000 connector series
Series example. Confirm the exact configuration and mating components before ordering.

Use the filters to compare available series. A series can appear in more than one connection category; its details and quotation request remain on the same product page. Matching pitch alone does not establish compatibility.

Start with the position of both boards

  1. Show the board arrangement.Provide a sketch of the PCB positions, mating direction and available space, including the required installed board spacing.
  2. Define both connector halves.Specify rows, positions per row and the intended mating components. For headers, include pin dimensions and socket engagement.
  3. Check both footprints.Review mounting, hole or pad layouts and connector dimensions on each PCB using the selected drawings.

Before requesting a quote

Review the complete interconnect between two PCBs

This category includes documented PCB connector pairs, pin headers and female headers. Compare the exact construction on both sides before selecting a series.

Installed geometry
Check the assembled board spacing, mating direction and clearance around both connectors. A housing height on one drawing does not establish the complete installed spacing.
Mating interface
Match contact arrangement, mating dimensions and engagement using both drawings. Equal pitch and contact count alone do not establish a compatible pair.
A documented PCB pair
The reviewed B3000 pair has two positions and right-angle SMT construction. Use its drawings for both PCB layouts; this example does not establish additional positions or mounting options.

B3000 drawing example. Review both pages for the documented two-position right-angle SMT pair. Open full PDF →

Prepare your configuration request

Include both connector references or drawings, rows, positions per row, board arrangement, installed spacing, mounting, PCB layouts, required ratings and quantity.

Standard connector samples are free, excluding freight. Typical production MOQ is 1,000–5,000 pieces per model or configuration. Packaging can follow your requirements.

For custom pin or female headers, typical production MOQ is 5,000 pieces per model or configuration. Samples are free when existing tooling supports the requested insulator height; otherwise sample charges are confirmed for the project. Free samples exclude freight.
