Both share the 2.50 mm pitch, shrouded 4-wall design, and tin-plated contacts. The 1744418-7 offers 7 circuits versus 3, and its friction lock mates with the standard Economy Power 2.5 receptacle latch — the locking ramp on the 3-position variant requires a different receptacle housing. For a 7-circuit BOM line, the 1744418-7 is the direct match.
Design engineers need full electrical and mechanical specs to validate fit.
Sourcing buyers need immediate purchasing options to fill BOM lines.
Compliance verification is mandatory for many industry and regional applications.
Cross-reference helps find drop-in replacements and second-source options.
Budgeting and cost comparison directly affect procurement decisions.
Pin configuration is critical for PCB layout and connection planning.
