Substitute Part Grouping Explanation

Substitution of the 641219-4 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 4 positions at 0.156" (3.96mm) pitch
Termination Method: IDC cable termination for 22 AWG wire
Mechanical Interface: Free-hanging in-line mounting with locking ramp fastening
Electrical Properties: Gold contact finish at specified thickness
Series Designation: MTA-156 series compatibility

Parts meeting all these criteria are classified as direct substitutes. Variations in product status, packaging, or compliance certifications do not affect functional interchangeability when these core parameters remain identical.
