  "account": "TE Connectivity part number 1888247 is a 20-position SFP+ connector for board-side termination, not an SFP cage. The same part is described with two different numbers, 1888247-1 and 1888247-2, which differ only in the thickness of gold plating in the mating area. TE groups these products under the SFP+ Product Family: Cages, Connectors, Cable Assemblies.\n\nThe SFP+ connector's 20-pad edge interfaces with the host board, while the cage mechanically aligns the module, provides EMI shielding, and is press-fit or soldered around the connector's footprint. Suppliers sell either standalone connectors, standalone cages, or combined cage-and-connector assemblies.\n\nTo find an alternative to the TE 1888247 SFP cage, you should instead search for an equivalent 20-position SFP+ connector and a cage that fits the same footprint. TE's product pages list the specified values for these two dash numbers: product type (connector), positions (20), centerline (0.8 mm), termination (surface mount), data rate (max 16 Gb/s), maximum contact current (0.5 A), operating temperature (-55 to 85 °C), and plating (gold thickness).\n\nWhen considering alternatives, verify the connector's pitch and termination, data rate, plating, and temperature range. Confirm the cage fit, and verify the candidate as a functional alternative through samples in your design, including footprint, module insertion, and signal integrity at your data rate.",
  "summary": "TE Connectivity part number 1888247 is a 20-position SFP+ board-side connector (receptacle) , not an SFP cage. On TE's product pages, both 1888247-1 and 1888247-2 are described as \"SFP+, Connector, .8mm [.031in] Centerline, Power & Signal\" with surface-mount termination and a maximum data rate of 16 Gb/s. The metal cage that guides the pluggable module and shields the port is a separate part. So…",
