Check each system separately and keep the exact model and conditions attached.
Needle system, needle size, bobbin identity, presser-foot attachment, embroidery frame and industrial subclass are separate questions. An answer about one does not establish the others.
A shared name or OEM number does not prove that a particular sales unit fits. An illustrated part reference and a reviewed exact-model application have different scopes. Package contents, substitutions and retail fitment need their own evidence.
If the source establishes an attachment procedure but no mount standard, use only the established answer. Read the safety conditions first and consult the applicable full procedure. Do not fill gaps from a sibling model.
The listed needle answer has its own operation and size conditions. It does not establish foot attachment, bobbin substitution or retail sales-unit fitment.
