Actually I have this hash but I don't know what cryptographic hash function generated it.

4753305A7A673D7A5A442156 I know password is 12345678 I extracted this pass from PLC device

Mitsubishi

Are you sure that there is no salt? –  Lucas Kauffman Jul 3 '12 at 14:38
    
There's no way to tell what the hash algorithm is by analysing the data. However, it does seem (after some Googling) that Mitsubishi's PLCs use a proprietary hash algorithm. Only way to find out would be to reverse engineer the PLC. –  Polynomial Jul 3 '12 at 15:05

Flagged as offtopic, but is also probably unanswerable. Suggest following @Polynomial's guidance and hunting down info on Mitsubishi PLCs –  Rory Alsop Jul 3 '12 at 15:44
    
Closed while I was providing some direction. If you think they implemented an existing hash, you might look at some cryptographic hash functions that output 96-bits. Such as Robert Jenkins hash, square hash, openswan truncates sha256 to 96bits, ipsec truncates sha1 or md5 to 96-bits. –  Phillip Nordwall Jul 3 '12 at 15:53
