Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 5033043040 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with center strip contacts
• Electrical Interface: 30-position contact arrangement
• Contact Pitch: 0.016" (0.40mm) spacing
• Row Configuration: 2-row layout
• Mounting Technology: Surface mount (SMD)
• Contact Material & Finish: Gold plating at 4.00µin thickness
• Physical Envelope: Mated stacking height of 0.7mm and height above board of 0.027" (0.68mm)
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The substitute part Molex 5033043042 maintains identical specifications across all these parameters. The primary distinction is packaging format and product status, not functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5033043042 is the direct functional equivalent to the obsolete 5033043040. Both parts share identical electrical and mechanical specifications, ensuring drop-in compatibility in existing designs. The 5033043042 carries active product status with ROHS3 compliance and MSL 1 rating, making it suitable for new production and legacy system support.

The primary difference between these parts is packaging format: the 5033043040 is supplied in bulk packaging, while the 5033043042 is supplied in Tape & Reel format with Pick and Place features. This distinction affects procurement and assembly processes but does not impact functional performance or physical compatibility.

For applications requiring bulk packaging, component sourcing should prioritize the 5033043042 as the active equivalent, with packaging conversion handled through distribution channels if necessary. The active status of the 5033043042 ensures long-term availability and supply chain stability compared to the obsolete 5033043040.
