ORIGINAL ROLAND P/N / MANUFACTURER P/N [QUAN] |
OPERATING FORCE (gf/NEWTON) |
MODERN DAY REPLACEMENT P/N |

(1)
|
The Roland P/N in the JV‑880 Service Manual is a typo listed as P/N: 13169684 and should be P/N: 13169697. The incorrect P/N has four leads and will not physically fit into the PCB. The Mitsumi P/N: SOR‑123HS and PANASONIC replacement P/N's are correct
|
|
(2) |
Mouser and other suppliers are starting to phase out this original ALPS replacement switch but a few places still sell these P/N's. ALPS: SKHVBD (100gf), SKHVBE (160gf) or SKHVBF (260gf). I have used the high quality PANASONIC modern day replacements on the U‑20 and JV‑880 with excellent results. However, these also have been scheduled for obsolescence and will be discontinued by the manufacturer very soon so... get 'em while they're hot!. If you can't find any Panasonic tact switch replacements, the B3F‑6020 & B3F‑6022 are good alternates |
|

This solitary RESET button for the S-550 is located inside the case on the Main PCB and is only used for testing and/or servicing. It rarely needs to be replaced because of non‑use
|
|
(4) |
I have found several typos in the Roland Service Manuals. Corrections have been made whenever possible but there is still a chance some errors exist. All entries with "Replacement DIY here" are accurate because I have replaced these tact switches myself and have verified the replacement P/N's. The S‑750 and S‑770 "Replacement Notes" are speculative |
|
(5) |
When I replaced the tact switches on my W‑30, the position of the Panel Board was slightly lower than expected. To make sure the tact switches worked properly when the buttons were pressed, I had to place a 1mm tall plastic spacer under each one while soldering them in place. I'm not sure if all W‑30's are like this or not?!? Please see the W‑30 tact switch reference image posted at the S‑50/S‑550 DIY webpage here |

 Things To Note
- The reason I have so many alternate replacements listed is because I prefer a harder press Operating Force of 260gf. I like to hear that solid 'Click!' whenever I make a selection
- I highly recommend mouser.com as a source for purchasing new tact switch replacements. Mouser offers large discounts for quantities of 10+ and 100+ and their prices are extremely low compared to the vultures selling full sets on eBay. When ordering, always get a few extra tact switches because... shit happens! In the past, I have received a few which were missing one or more PCB pins due to a quality control issue or damage due to a shipping mishap
- For unknown reasons, tact switch manufacturer ALPS has recently tripled their prices on some products. Most of the "Replacement DIY" links will show alternate part numbers from tact switch manufacturer OMRON
- With the exception of a few synth and sampler models, Roland used ALPS brand tact switches exclusively on models manufactured from the mid-1980's through the late 1990's. OMRON and PANASONIC are also high quality brands to use as replacements
- While searching for modern replacements, I discovered that OMRON has a series of High-Reliability Gold-Plated tact switches. If you are totally obsessed with your synths and samplers, these are for you. The OMRON B3F‑1000‑G, B3F‑3000‑G & B3F‑5001 series are resistive to corrosive gas and priced at $3 per switch!!!
