Help. I have gotten three voltage regulators from the normal Porsche Parts suppliers and none fit. The distance from edge of case to the first spade is .25 inches on my original regulator. The catalogs all show same regulator for 911, 914, and 914-6. The ones I have received vary from .4 from the edge to .65 from the edge all with same PN so will not fit in area to plug into. Anyone know the actual part to buy? My original has numbers on it in this order 0 190 601 006 AD 1/14V. The replacements show up as PN 901 603 206 02 Yes I can rewire, or maybe take both apart and move the guts, but trying to keep original and not have a wire harness to convert to get wires to new regulator. Thank you for your help. TimAttached Image

I was going to recommend the Bosch transistorized voltage regulator for you (043-903-803-B) but holy crap, PP has them for $250!! That's insane, maybe if they were made of solid gold. I see that Airhead Parts has them for $138.85, cheaper but still outrageous. If you can find a cheaper source, this Bosch regulator is the best one.

Looks like Hella offers an equivalent for a fraction of the price, $32.33

https://www.vividracing.com/catalog/-p-1513...8W4caAqI08P8HAQ

Pelican Parts has the same Hella regulator for $34. I've never used one, maybe someone here who has can comment. Looking at the comments on PP there seem to be fitting problems, not dissimilar from what you've experienced.

That replacement one you have looks like the cheap auto parts store version, I never had much luck with those, they were barely better than the old mechanical Bosch units (like your old one).

Thank you for your help. The Airhead site shows as: OE Bosch Solid State Version 0192062007. Type 2 Bus w/AL75 or AL108 Alternators, Type 4 69-74. Replaces Bosch 0190600016.

At least they have the Bosche PN listed and it is close as 600 vs. 601.

Be careful, not all will fit correctly.
I know I bought one of Ebay that was supposed to fit a 914, but nothing lined up right. So yes a fitment issue.

I have ordered the one from airhead taking the chance same company, same engine, alternator vs. generator, and same years in the hope it may work. The guy at Airhead was very helpful and measured distance to the pins and looks close.

How MANY old style do you want? I have 6 NOS Bosch old style ones. I have a source for 10 more if they are needed. They are universal fit and have large holes. A large washer takes care of the problem.

FYI: None of the aftermarket fit right. Bosch early and the late 1/2 size are the only ones that fit correctly

Here's a pic of the half height, transistorized Bosch regulator installed in my car. Fit was no issue.

Here's another possible VR that looks similar to the $$$ transistorized Bosch unit. Anyone try one of these?

I purchased one of those too, pin location was off .15 inch so would not fit in location.

Thank you everyone for your help! The Airhead PN 043-903-803B arrived, fit great, and the gages appear to be calibrated correctly, so it appears to be a functioning replacement.

Does anyone know if the replacement electronic ones last more than a few years as the original made it 45 years. Thinking might buy one of the OEM replacements just to have on shelf. Thank you all again. Tim

Mine's been reliable, it should be more reliable than the OEM mechanical regulator.

I try to have a spare of just about every part I can get. Every year more things go NLA and the price of replacement goes up. Keeping a stock of parts on hand can help ease the pain, and also helps when you need to do troubleshooting.

No the Beru ones have the same dimensional problems and won't fit with the plastic relay board cover in place.

I bought a NOS Bosch regulator in the end and am relieved to read others problems posted here I thought I was alone struggling with this issue.
