| Key distinction | Count positions and contacts separately. | Same position count can hide a different populated layout. | Handset and telephone-line connections are different questions. |
Illustrations are computer-generated with prior AI visual review; independent technical and rights review pending. A comparison is not a compatibility verdict.
All selected records are Connector records. Similar layer does not mean compatible, interchangeable or safe to mate.
Families represented: Telephone
Look here first
Not a size comparison. Illustrations fit the same display boxes; their physical dimensions are not shown to a common scale. No mating or compatibility verdict follows.
P111 / Front-oriented modular sketch
Role not specified
Visible clue: Four filled contact marks within a six-position outline
Filled versus unfilled marks illustrate population, not wire order.
Still check: The RJ11 trade label does not establish a complete wiring or equipment-role description.
P112 / Front-oriented modular sketch
Role not specified
Visible clue: Six filled contact marks within a six-position outline
Contact population is separate from signal assignment.
Still check: A shared housing is not proof of the same wiring, service or device role.
P113 / Housing-only modular symbol
Role not specified
Visible clue: Read the four-position housing label, not a contact pattern
The contact area is deliberately blank; do not infer four populated contacts.
Still check: No populated contacts are depicted. This cannot establish handset wiring or a telephone-line connection.
