Q1: What are the main features of the DF40C-50DS-0.4V(51)?
The DF40C-50DS-0.4V(51) is a high-density board-to-board mezzanine connector from Hirose's DF40 Series. It features 50 positions with a fine 0.4 mm contact pitch, a compact 1.5 mm mating height, surface-mount installation, gold-plated contacts, and support for transmission speeds up to 20 Gbps. The connector is designed for reliable signal integrity in compact electronic products and supports applications such as USB, PCIe, SATA, and MIPI interfaces. It is rated for 0.3 A current and operates across a temperature range of -55°C to +85°C.
Q2: What is the DF40C-50DS-0.4V(51) used for?
This connector is commonly used in compact electronic systems that require high-speed board-to-board interconnection. Typical applications include industrial controllers, embedded computing modules, communication equipment, portable devices, cameras, display modules, medical electronics, and other space-constrained designs. Its small footprint and high-speed performance make it suitable for connecting daughterboards, processor modules, and high-density PCBs.
Q3: Does the DF40C-50DS-0.4V(51) have alternative manufacturers and part numbers?
Yes. Similar board-to-board mezzanine connectors are available from manufacturers such as Molex, JAE, Samtec, Panasonic Industry, and TE Connectivity. Comparable part numbers should be selected based on the required pitch, number of positions, stacking height, current rating, transmission speed, and PCB footprint, so the best substitute should be verified against the exact design requirements. Industry engineers frequently compare Hirose DF40-series connectors with similar high-density mezzanine connector families from these manufacturers when designing compact systems.
Q4: Is technical support available for this part?
Yes. Technical support is available through Hirose Electric and authorized distributors. Support resources typically include datasheets, 2D and 3D models, PCB footprints, mating connector information, application guidance, and design documentation. Distributors such as Nantian Electronics can also assist with product selection, availability, datasheet access, and purchasing support.
