Particle Electron / Asset tracker components


I’m looking at the getting a project I’ve made into a single pcb - but the company doing this is having trouble finding these components
• Kaweei S25432-36G-M71-1F
• Kaweei P1163-0140R
• Murata SAFB1G56KB0F0A

Can any point me in a direction of what they are and any alternatives preferably able in the UK
