Chainsaw Chain Cross Reference Chart | Stihl, Oregon, Carlton & Husqvarna
Chainsaw Chain Cross Reference Chart
Every Alpine Chain Co. model code tells you the chain’s exact specification. This chainsaw chain cross reference chart decodes the Alpine system and maps each size to its Stihl, Husqvarna and Oregon equivalent, so you can match your old chain to ours with confidence. It's part of our complete chainsaw chain size guide — if you'd rather look up your chain by saw brand and model, start there.
How to use this chart: find your current chain's brand code in one of the columns below (or work out your pitch and gauge first), then read across to the matching Alpine size. The two tables cover semi-chisel (-S) and full-chisel (-F) chains separately.
How to read an Alpine Chain Specification Code
- Prefix = pitch: NN (Nano) = 1/4" · LT (Lite) = 3/8" LP · EN (Endurance) = .325" · PF (Performance) = 3/8"
- Number = gauge: 43 = .043" (1.1mm) · 50 = .050" (1.3mm) · 58 = .058" (1.5mm) · 63 = .063" (1.6mm)
- Suffix = cutter: -S = semi-chisel · -F = full-chisel
Example: an EN58-S is a .325" pitch, .058" gauge, semi-chisel chain.

Reading the other brands’ codes
Stihl: RM and PM families are semi-chisel; RS and PS are full-chisel. Oregon: BPX, DPX, PX and AP families are semi-chisel; LPX and EXL are full-chisel.
A dash (—) means that brand doesn’t offer a direct factory equivalent in that size — match on pitch, gauge and cutter type instead. NN43-F, NN50-F, LT43-F and EN43-F have no mainstream OEM equivalent, and our PF63-SM skip-tooth milling chain is an Alpine-specific configuration.
Pitch and gauge must both match your bar exactly — they are stamped on the bar near the mount. Chain length varies with your bar; each Alpine product page lists the lengths available for that size.
Found your equivalent? Find your exact chain
Once you know your Alpine size, match it to your saw exactly. Enter your model in Search by Chainsaw, or use Search by Bar Stamp if you have your pitch, gauge and drive-link count to hand.
