It uses a surface-mount, top-mounting style with a 25° insertion angle, making it suitable for applications where the memory module sits parallel to the motherboard and loads at an angle for retention. The 144-circuit count matches the standard DDR1/DDR2 SODIMM interface. The connector accepts a card thickness of 0.039\" (1.00mm) and stands 0.196\" (4.00mm) above the board when mated—this stack height is the z-height budget you need to clear the enclosure lid or adjacent components. For BOM lines that call out this exact order code, sourcing runs through independent distribution channels. The board layout and mating half (standard 144-pin SODIMM module) are well-defined, so a pin-compatible substitute would require the same pitch and keying—verify against the original design-in. The board guide and latches (listed features) help align the module during insertion and lock it against vibration-induced unseating. The 25° insertion angle is a mechanical constraint for the module loading path—ensure the enclosure has enough clearance above the connector to pivot the memory module in and out. The white housing color is a visual aid for assembly verification on the line.","metaTitle":"Molex 0546977001 SODIMM Connector – 144-Pin, SMT, Obsolete","metaDescription":"Molex 0546977001 – 144-position SODIMM connector, SMT, top mount, gold contacts.
