ISO7841: Inquiry about pcb solder mask

Part Number: ISO7841

Hi team,

Good day!

My customer is using NSI8241W0-DSWWR. The package is SOP16(600mil) as below. They are using the clearance& creepage optimized version pcb.

ISO7841FDWWR is p2p material. The pcb solder mask is as below. Is there any problem if customer use ISO7840FDWWR directly to replace NSI8241W0-DSWWR using its clearance optimized version pcb?

Regards,

Victoria
