Compatibility first

Reviewed answers at a glance

These states come from the cited public evidence, not from model-code patterns. Unknown is never treated as incompatible.

Compatibility field map

What is established—and what is still separate

A core answer does not complete every physical axis. Each field below is shown only when current accepted OEM evidence establishes it; all other axes remain explicitly unestablished.

Bobbin

Bobbin class or system
Not established in current accepted evidence
Exact OEM Bobbin part
Not established in current accepted evidence
Bobbin material and dimensions
Not established in current accepted evidence
Loading style
Not established in current accepted evidence
Bobbin case
Not established in current accepted evidence
Hook system
Not established in current accepted evidence

Important: loading style does not establish Bobbin class, hook orientation, or interchangeability.

Needle

Needle system or type
DC×27

Supported sizes

Exact OEM Needle part
Not established in current accepted evidence
Needle count and insertion

Twin or special-use limits
Not established in current accepted evidence

Important: a recommendation is not an exclusive system requirement unless the OEM says so.

Presser foot

Attachment or mount
Not established in current accepted evidence
Shank or presser-bar geometry
Not established in current accepted evidence
Holder or ankle
Not established in current accepted evidence
Adapter requirement
Not established in current accepted evidence
Stitch-width and clearance limits
Not established in current accepted evidence
Dual-feed or walking-feed system
Not established in current accepted evidence

Important: a Snap-On attachment does not establish shank height, holder geometry, stitch-width family, or broad foot fitment.

Machine facets and OEM groups

Cited machine facets

Identity and compatibility badges

Identity families, physical traits, and OEM accessory groups stay separate. A group badge applies only to its named program and domains.

Unknown is not incompatible. A missing answer means the current official evidence does not support one yet.

Specifications

Documented machine facts

Multiple cited representations for one field share one row. SewGraph preserves every value and exact proof passage; it does not guess which representation is “raw” or “normalized” when the public projection does not label that distinction.
