We are looking for a drop in replacement for a ST62T10CB6 which wwe can't buy anymore

[ICohe.1]

The ST62T10CB6 is an OTP but the replacement may be any chip with the same footprint. 

We can edit the program if it will be required.

Any idea ?

If you can't find in the secondary market you might want to consider a design refresh using current parts.

If you have an existing business relationship with ST contact your local sales office, or FAE, to see if the have a migration path for the obsolete parts, or can suggest a design house with experience doing migration projects.
