Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 423563 is determined by the following critical parameters:

Position Count: 80 positions is the primary functional requirement. Substitute parts must maintain this exact position specification.

Cable Exit Configuration: 180-degree cable exit is a mechanical requirement that determines physical installation orientation and cable routing. Substitute parts must provide identical exit angle.

Shielding Requirement: Shielded construction is specified for electromagnetic interference protection. Substitute parts must maintain shielded design.

Accessory Type: Two-piece backshell construction provides the functional equivalent to the original component.

The TE Connectivity AMP Connectors part number 749196-2 satisfies all these critical parameters and is classified as an active product with current manufacturing status.
