Already found the diode - but thanks.

Thanks - I just updated my post #19 to add the diameter. It's in inches though - I don't have any tool that measures in metric.

[redwire]

Just to get the sizes right: dia. X height, LS means lead spacing. These are always in Metric though.
Originals look like CapXon KM series rated 2,000hrs life. So I took those dimensions as a start:

C3, C10 - 100uF 16V 6.3x11mm LS=2.5mm
C4 - 470uF 25V 8x11.5 or 10x12.5, LS=3.5mm
C5 - 1,000uF 25V 10x20mm LS=5mm; but looks bigger, is this a 12.5mm part (1/2")???
C13, C14 - 0.47uF 50V electrolytic 5x11mm LS=2.5mm?
D11 - 1N5231B 5.1V 0.5W zener
U4 - L78L08ACZ voltage regulator 8V 0.1A
Relays - Siemens T7CV5D-12-02, 10A 250VAC, 12VDC coil.

If this is right, we can give some possible part numbers for the caps.

C4 - 470uF 25V 8x11.5 or 10x12.5, LS=3.5mm (I get 9mm X 16mm tall)

C5 - 1,000uF 25V 10x20mm LS=5mm; but looks bigger, is this a 12.5mm part (1/2")??? (I get 13mm X 21mm tall)

The black skinned caps are marked "KM" and the orange skinned pair (C13 and C14) are marked "LL" - I'm not absolutely accurate on the sizes. I'm using a measuring tape, then converting decimal to metric. So, I'm close, but could be off slightly.

See dark red text above embedded in your reply

Caps come in standard (Metric) size categories. Look for these long life parts:

C3, C10 - 100uF 16V 6.3x11mm LS=2.5mm bent to 3.5mm (OK to sub 25V parts)
Nichicon ULD1C101MED1TD
Chemi-con ELE-160ELL101MF11D or ELE-250ELL101MF11D (25V).
Rubycon 25YXM100MEFR6.3X11
---------------------------------------------------------------------------------
C4 - 470uF 25V 10x12.5mm LS=5mm (long life parts are usually taller like 16 or 20mm)
Rubycon 25ZLH470MEFC10X12.5
Nichicon UHE1E471MPD6TD or UHE1E471MPD6.
Chemi-con EKY-250ELL471MJ16S
Panasonic EEU-FR1E471
---------------------------------------------------------------------------------
C5 - 1,000uF 25V 12.5x23mm LS=5mm; more common size is 10x20mm
Chemi-con EKY-250ETD102MK20S 12.5x20
Nichicon UHW1E102MPD 10x20
Panasonic EEU-FR1E102 10x20
Rubycon 25ZLH1000MEFC10X23 10x23
---------------------------------------------------------------------------------
C13, C14 - 0.47uF 50V electrolytic 5x11mm, instead use 0.47uF 50V polyester (these have no polarity) w/leads splayed out a bit, like Kemet
---------------------------------------------------------------------------------

Does the polyester cap still need to be Low Leakage like the original caps? I can't find one that has that spec (at all). Thanks for looking up the others.

[redwire]

A film capacitor inherently has much less leakage current than any electrolytic capacitor, so I see no penalty to using them aside from the lead spacing being a bit bigger at 5mm.

[stj]

some polyester are tall and square if you look hard enough - those can fit inplace without any lead bending
dont skip looking at 63v and 100v ones to find a good size/shape

[redwire]

The board has 5mm hole spacing, with the original 0.47uF having their leads bent out to that. So 5mm I think is fine. I did see some 2.5mm polyester caps but no stock anywhere. Wild guess they are for filtering the temperature sensors.

I found some Nichicon .47uf, 50V, low leakage electrolytic caps on DigiKey. The only difference was they are rated 1,000 hour (vs 2,000 hour).

Would these be a better choice than a poly film cap?

[stj]

no

I found only one polyester cap (with the correct specs) on Mouser - aside from the mounting style, do you think it's a good replacement for the original electrolytic 0.47uf, 50V, 105c Cap that is no longer available?

Here's the link: https://www.mouser.com/ProductDetail...d%2FkdEg%3D%3D

50v is uncommon for film caps - you should have used 63v in your search.
a better fit for less than a third of the price

[redwire]

Yes, best at Mouser is Kemet R82 series: 0.47uF 63V polyester $0.37 LS=5mm
https://www.mouser.com/ProductDetail...5Rakrliw%3D%3D

alternate Epcos/TDK B32529C0474 https://www.mouser.com/ProductDetail...vfa9fnmw%3D%3D but there are many offerings with 5%, 10% tolerance packaged in bulk, ammo pack, adding to the head spinning list.

Thank you - that is a much better fit physically.

Thank you (for all your help). I just put the KEMET cap in my cart and will order it.
