The Molex 0877159106 is a 64-position PCI Express card edge connector from the 87715 series, designed to accept standard PCIe add-in cards. It uses a 1.00 mm pitch with dual read-out contacts across two rows, meaning the connector reads signals from both sides of the card edge — the standard arrangement for PCIe x16 slots that need 64 differential pairs plus power and sideband signals.
Contact Finish and Termination
Termination is through-hole with staggered solder tails, which eases board routing by breaking the pin field into two rows that can be fanned out on inner layers. The specified card thickness is 0.062" (1.57 mm), matching standard PCB thickness for PCIe add-in cards.
