The MAX1556 was placed on the board. These two parts work\ndifferently WRT to the programming pins D1, D2.\nIf the MAX1556A had been used we would have been fine.\n\nI see no stock not his part at Mouser or Digikey or Newark, or anyone in the\nUS so far. I do see inventory in ASIA. If they will sell a small quantity of\nsay 16 we should be able to swap out the parts. Shipping cost will be $40 to\n$60.\n\nThis part is now Obsolete at Analog Devices.\n\nI think these part was used on earlier AMSAT boards. I would like to know if\nthere is any inventory available before ordering the parts from Asia? We\nneed a minimum of 8 but I would like to have 16 to be sure we get them\nsoldered on the boards.\n\nBob\n\n\n-----------------------------------------------------------\n\npacsat-dev mailing list -- [email protected] View archives of this\nmailing list at\nhttps://mailman.amsat.org/hyperkitty/list/[email protected]\nTo unsubscribe send an email to [email protected] Manage all of\nyour AMSAT-NA mailing list preferences at https://mailman.amsat.org\n\n", "attachments": [] }
