Engineering Selection Recommendations

Selection between 1PMT5933C/TR13 and 1PMT5933BT1G can be based solely on product status (active), RoHS and REACH compliance, ECCN, and HTSUS designation. The substitute 1PMT5933BT1G (onsemi) is ROHS3 compliant and REACH unaffected, while the main part 1PMT5933C/TR13 (Microchip Technology) is RoHS non-compliant. Both have unlimited moisture sensitivity level and identical regulatory status (EAR99, HTSUS 8541.10.0050).
