The integrated ground bus plane provides a low-inductance return path for high-speed signals, reducing loop area and common-mode noise. No official replacement part number is published. The 40-position, 0.050\" pitch Micro-Strip footprint is not a standard commodity, so a board redesign to an active series (e.g., TE's 0.050\" pitch Mezalok or a 1.27 mm pitch header from another manufacturer) may be the long-term path.","metaTitle":"5536279-1 TE Connectivity Micro-Strip 40-Pin Receptacle","metaDescription":"5536279-1 TE Connectivity AMP Micro-Strip board-to-board receptacle, 40 positions, 0.050\" pitch, 30 µinch gold mating finish.
