MK 251 42 Z is listed in the Headers, Male Pins range at ChipApex. The manufacturer field lists Fischer Elektronik. Its product description is Solder and plug pins, D0.5 mm. Review the specifications below when checking this part for your BOM.
The MK 251 42 Z is a through-hole right-angle pin header manufactured by Fischer Elektronik. It features 42 contacts arranged in two rows with a 2.54 mm (0.100 inch) pitch. The connector utilizes CuZn-alloy contacts with tin-plated surfaces and Ni+≥0.2µm Au or Ni+46µm Sn finishes. Designed for board-to-board and wire-to-board connections, it supports reliable rectangular PCB interconnections.
Verify the specific contact surface finish required for your application, as the product line offers both Ni+≥0.2µm Au and Ni+46µm Sn options. Confirm that the 42-contact, two-row configuration matches your design requirements. Ensure compatibility with standard 2.54 mm pitch mating connectors to guarantee proper mechanical and electrical engagement during assembly.
Select this component when a right-angle, through-hole header with 42 positions is required. The 2.54 mm pitch ensures compatibility with standard PCB layouts. Consider the contact material and plating options based on environmental conditions and mating cycle requirements. This model is suitable for applications needing robust, precision-engineered connections in electronic assemblies.
The MK 251 series consists of precision-engineered solder and plug pins specifically designed for reliable rectangular PCB connections. These components feature a 0.5 mm diameter pin design, ensuring stable electrical performance. Fischer Elektronik manufactures this series to meet high-quality standards for the electrical and electronic industry, offering various contact counts and configurations within the same structural family.
Compatible substitutes include other Fischer Elektronik MK 251 series headers with different contact counts, such as MK 251 18 Z. Ensure any replacement maintains the 2.54 mm pitch, two-row layout, and through-hole right-angle mounting style to preserve mechanical fit and electrical connectivity.
