Engineering Selection Recommendations

The Molex 0908140508 is the direct substitute for the obsolete Molex 0934050508. Both components are manufactured by Molex and maintain identical electrical specifications, mechanical dimensions for mating interfaces, contact configurations, and compliance certifications.

The substitute part offers the following advantages:

Active product status with current manufacturing availability
Identical electrical ratings (1.2A, 250V)
Identical contact pitch (1.27mm) and mating contact length (2.15mm)
Identical shrouding, fastening, and termination specifications
Full compliance with ROHS3 and REACH requirements
UL94 V-0 flammability rating maintained
Standard Tape & Reel packaging for production environments

The insulation height difference (0.203" vs. 0.252") reflects design evolution within the Picoflex series and does not affect electrical or mechanical compatibility for standard board-to-cable applications. Both components are rated for automotive, general purpose, industrial, and medical applications.
