Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 1889130000 is determined by the following critical parameters:

• Pitch (Contact Spacing): 5.08mm (0.200") — ensures mechanical and electrical alignment with mating connectors
• Number of Positions: 19 — maintains circuit density and connector footprint compatibility
• Connector Type & Orientation: 90° orientation with free-hanging (in-line) mounting configuration
• Electrical Ratings: Voltage and current specifications must meet or exceed application requirements
• Termination Method: Screw-clamping technology for secure wire attachment
• Regulatory Compliance: REACH and ECCN classifications must remain consistent

The substitute part 1949970000 satisfies these core parameters, providing functional equivalence for applications previously utilizing the 1889130000.
