Yamaha 300-series nozzles: identifiers and selection
Review the source-listed 309A SMT placement nozzle with ordering reference KHN-M7790-A1X. The 309A identification belongs with its full KHN code. A 301A or 302A listing is a separate selection, even when a supplier puts all 300-series nozzles in one catalogue. Start with the installed nozzle code and head documentation; then compare the contact face, pickup opening and clearance around the component.

02 / Check before ordering
Match the installed part
The family page groups related variants; it does not imply that variants are interchangeable.
- The 309A identification belongs with its full KHN code. A 301A or 302A listing is a separate selection, even when a supplier puts all 300-series nozzles in one catalogue. Start with the installed nozzle code and head documentation; then compare the contact face, pickup opening and clearance around the component.
- Record the complete installed part number, including every prefix and revision suffix. Include the machine and head identifiers plus photographs of the installation position.
- Request a quotation for the selected code and quantity. Ask the supplier to disclose maker, condition, exact revision, included items and available inspection evidence before acceptance.

04 / Care and handling
Maintenance and handling guidance
Keep the nozzle identifier attached to its maintenance record. Record the symptom, tip condition and machine or head position before changing parts, so a repeated pickup fault can be investigated without losing its history.
Use the machine maker's procedure for this exact nozzle. This reference does not establish an approved cleaning chemical, ultrasonic setting, air pressure, lubricant or replacement interval. Segregate suspect tips and require documented inspection before returning them to production.

Questions about this family
Can the family variants replace each other?
No interchangeability conclusion is made here. The variant table preserves source-listed identifiers; require the applicable parts manual or written technical cross-reference for the installed head and revision.
Are all variants photographed?
Only 309A has a retained source-listed image in this draft. Other variants, where listed, have no matched picture; missing angles and label views remain open evidence requests.
Is this an available, tested or genuine unit?
Availability, condition, origin and functional test results have not been verified. Send the exact part code and quantity for a unit-specific enquiry; this reference page is not an inventory offer.
