Pandas version checks

  • [x] I have checked that this issue has not already been reported.

  • [x] I have confirmed this bug exists on the latest version of pandas.

  • [ ] I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import pandas as pd
import numpy as np
import datetime
pd.DataFrame([np.nan], dtype='datetime64[ns]').replace(np.nan, datetime.datetime(3000,1,1))

Issue Description

code above gives this error, likely because the datetime is too big for datetime64[ns]:

pd.DataFrame([np.nan], dtype='datetime64[ns]').replace(np.nan, datetime.datetime(3000,1,1))
