No easy answer.
First -- the DA3CB1AA had a "button" force of 90 grams.
The replacement series is DB3CB1AA which has a "button" force of 150gr.
The DB5 has a "button" force of 70 gr.
What max force really should be is anybody's guess.
The plain DB3CB1AA is a button type switch with no actuator provided. It expects the user to provide or reuse the existing actuator.
The DB3CB1LB mentioned above is the exact same switch but with an actuator preinstalled. This actuator is what drops the button force from 150gr to about 62gr... and the actuator that is installed is probably not the one you want anyways.
There is no Cherry (ZF) direct replacement for the original DA3's but the DB's are closest, electrically. C&K switches have three options for actuation force. The C&K LCGD part would have been a better choice except these have been obsoleted and are no longer available.
Low current switches (i.e. DB3C) tend to have a lower 'on' resistance than the higher current switches (i.e. DB5C) and are more suited for switch matrixes. Downside to low current switches -- they cannot be used for high current locations such as directly controlling flippers (although some people try this anyways).
The higher current switches (i.e. DB5C) tend to have a higher 'on' resistance than the lower current switches and are not intended for switch matrixes. Tradeoff -- higher button force versus higher switch resistance. Problem with the ZF switches -- they no longer post the 'on' resistance for their switches.
