The DO-201 axial footprint is common, so a replacement from another manufacturer with the same package and electrical window is possible but requires BOM-level validation. ## Temperature range and deployment context The through-hole DO-201AA axial package is a legacy form factor; it mounts in boards designed for wave-solder or hand-solder assembly, common in retrofit or long-life industrial equipment where SMD alternatives would require a layout change.","metaTitle":"1.5KE6.8-B Littelfuse Zener TVS, 1500W, DO-201, Obsolete","metaDescription":"Littelfuse 1.5KE6.8-B Zener TVS diode, 1500W peak pulse power, 5.8V standoff, DO-201 axial.
