Hi All,

I just ran across something that was brought to my attention about the MSL
rating for a Microchip TQFP80 part, PN# PIC24FJ256GA108-I/PT
<https://analytics.supplyframe.com/trackingservlet/track/?r=gPVv3S5fz9WS0muSSENj7rO6t8VXvQgK1rcMoyYTG0FvQlD0DIEzVjQKFnEXzjwd-qWoH4WrGz915jp9zrn-G-x_qSIVtc8zbLug-SAwCiq0p74rp1VjbJ2KwYhfTKtPqXxcTKsKZYCGGxofwy72prM2kZSCtGHPF0yQzQAytU_QVib44Cu-IBWW40DIyeoDrEQTNcmOi-iuSYSbwoo9uOWkwMsYOgLpgGtKwmlenCQ2qMUd-IluZU4hJMiMAwmQlvALZwlfnfe9p0y3-ada-0yro_rIN4ri1yG9W-ZAXgWcwuQI3v44ByozahmNdDu-pP83qBz7C1LvOj23z4u80ql5EFxO_M1uaNi8HamPkYIv5nst4jWzwTx9kLe371AdpR1Zade37d-Lbj994RtcoMlt-_tywF_Sm-fI_q-cK0pdzb47WLG3M1qI1PK3dWAQdVdSoATlHSFiOVsTCt_saqPqKUpH5GxSz0S4qHYNHBJVeAvg0srqjam2tMTKtH_4ep6RpxaZMva-9pU_Ey3iAJVT9HvW2kqUcoDZQO-bB3n0i_E50WvzT7FtGb8AY1fX6J8wP7q1t6XJ9Y4gX2enmlUGVq5roSzf_LM_4qzxpZ1mlezG7b5aZxH2oGmw_vefrS7sZbKNHTFjh_Gdgyz4FHrdsp4ysX9vdVTIZyEMa-IrUGN_7E6JEROsA7dEt5NZikg5mrq17ntQe8y7r5_MjRGjrWr9d7d57c8NJ-HE_WJMCK9KvwQMbI2rzs_fn0ogzAshEeM8su_nJNSXQoJ6-WVWH9LR26AGY4y0d3PuCaOSBGsxFFiaSHOaBnl8Zc4tVZjXxT68gr9bJ8R3-PsNm7SjxGiIymxAijZ7Qb4quJc>
the part came in from Future and they put a MSL1 label on it and the
package wasn't sealed. One of our more knowledgeable technicians wanted to
double check the rating because he knows that QFP's are normally MSL3 or
higher. The Digikey page calls this a MSL3 part, but if you go to Avnet's
page it gives this a 1/3 MSL rating...what is that? I have never heard of a
1/3 MSL rating. I have also looked at the 305-page datasheet and can't find
a MSL rating in the Microchip documentation. Has anybody ever seen this
before?
