I have a buck converter circuit I am using for a project. A PCB using the circuit will be made and assembled by JLCPCB (I have already used them for another PCB I designed and had them make with very satisfactory results). The design for the new board (from Texas Instrument WEBENCH Design Report and using a TLV62569DBV IC) calls for an Abracon ASPI-0530HI-2R2 35.0 mOhm Inductor
This item is not available from JLCPCB so a substitute I have identified from the JLCPCB (LCSC) parts list is the Bourns
OR the TDK
Both of these have very similar characteristics in some areas but vary in others and I am not sure if I am reading the results properly so hope someone may be able to help me understand.
The DCR (or RDC??) appears to be 35 mOhm and inductance is 2.2uH both as required. But the Saturation Current (Isat) and Tmp Rise Current (Irms) appear to be significantly lower than the Abracon ASPI-0530HI-2R2. Should I be too concerned about these differences as long as the DRC and Inductance are OK or are they a vital part of the spec and must be met? If they are vital then I will have to continue my search and currently there appears to be a shortage of components so finding an available, adequate substiute is difficult.
Bob I am hoping you may have a comment on this.
