The whole point of a custom typeface is that it’s unique; the following suggestions are decent substitutes based on overall form and proportions, but may miss on some of the details (DIN comes closest on both the numerals and the letters).

Thanks KThomps. I keep coming back to DIN for my project, and then avoiding it again b/c I'm worried that when the text is read by Germans it will conjure street signs. But I like the Parachute families. Thanks.

You could commission a custom font from Lineto, or another foundry. Or you could modify Typ 1451, but: it's not easy to do a clean job; you have to make sure the results don't leak out to the world.

DIN does indeed have too much baggage.

Some more food for the mind jilljill: Netto, Isonorm, Rubrik, Speak, Chevin, Mic32 New, Dosis (good for text?), Bariol (see Dosis)
