Mapping int to strings

I've got some ints (1-6) that I need to convert and map to say 1a, 2b, 3c, e.g. strings.

For normal mapping to ints I'd just use

SELECT SomeInts, case when SomeInts = 1 THEN 2 when SomeInts = 2 THEN 3 ELSE 999 END AS SomeIntsNEW FROM SomeTable

But if I try to change the first THEN to '2a' I get this:

Conversion failed when converting the varchar value '2y' to data type int.

I've tried various variants over cast/convert but none worked.

Whats the right syntax?

declare @t table (col1 int)
insert into @t values (1),(2),(3),(4),(5),(6)
select col1
,CASE
WHEN col1=1 THEN CONVERT(varchar,col1)+'a'
WHEN col1=2 THEN CONVERT(varchar,col1)+'b'
WHEN col1=3 THEN CONVERT(varchar,col1)+'c'
WHEN col1=4 THEN CONVERT(varchar,col1)+'d'
WHEN col1=5 THEN CONVERT(varchar,col1)+'e'
WHEN col1=6 THEN CONVERT(varchar,col1)+'f'
END conversion
from @t

Cheers
