Epson Timing Devices - Pure SN and ROHS suffix

When looking at the part number format of Epson timing devices, there may be 2 suffix options – “ROHS” and “PURE SN” available, for example, MC-306 32.7680K-A: ROHS vs MC-306 32.7680K-A: PURE SN.


Both suffix are indicating ROHS Compliant.

“RoHS” parts may have some impurities but qualify under the exemption. “PURE SN” is pure tin with no impurities.
