Compatible chips with AMB29f400-70SE

I have 2 of these chips both read/erase etc fine but writing either don't start or sticks at 14% so looking to see what other chips I can use as replacements

First need ERASE Flash!!!

Check connection on Adapter and clean the pins from Flash

I can say, my Willem Programmer with adapter PSOP44 Read & Write Perfect.
Do it many time with the same 29F400BB -70SE
