The two most common aftermarket communication adapters are the NEXIQ USB Link and the DG Technologies DPA5. Customers quite often ask us: What’s the difference? Well, we’re here to break it down for you.
The Nexiq USB Link is manufactured by Nexiq, which is owned by Snap On. This is by far the most common adapter, as they have a very large distribution network and brand name recognition. Below is our list of Pro’s and Con’s on this adapter:
Pro’s
1.Aftermarket cable ends are readily available all over the Internet around $30 each.
2.You can buy them anywhere – Your Snap On Heavy Duty Truck Scanner, dealerships, Internet, etc…
3.If repairs are needed after warranty has expired (12 months), Nexiq repairs them at reasonable pricing.
Con’s
1.Only has a 12-month warranty
2.No diagnostic software included
3.There are TONS of Chinese clones/knock offs so be careful where you buy from
4.The most expensive aftermarket adapter available
5.Item is manufactured out of plastic (Not as durable as others)
The DPA5 adapter is manufactured by DG Technologies, which was previously called Dearborn Technologies. While a smaller company, they do a lot of business directly with manufacturers such as Case New Holland, Detroit, and more.
Pro’s
1.Priced competitively ($75 or so less than a Nexiq)
2.Standard 2-year warranty and extended warranties available
3.Made out of metal, so very durable
4.Comes with aftermarket diagnostic software
Con’s
1.Customers are unfamiliar with the name
2.Does not support J2534, which means it will not work with 2005 & older Fords
3.Cable ends beyond the standard 6/9 pin cable are more expensive ($55 each)
So there you have it, the major differences between the adapters explained. So what is the best option for you? Honestly, it depends on if you want name brand recognition (Nexiq USB Link) or something that costs less money and has a better warranty (DG Technologies DPA5).
