Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 5033046040 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with center strip contacts
• Position Count & Pitch: 60 positions at 0.016" (0.40mm) pitch
• Row Configuration: 2-row arrangement
• Mounting Technology: Surface mount with identical board height
• Contact Material & Finish: Gold plating at 4.00µin thickness
• Series Compatibility: SlimStack 503304 series designation
• Compliance Standards: ROHS3 compliance and MSL rating

The substitute part 5033046042 maintains full equivalence across all electrical and mechanical parameters while differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5033046042 is the direct functional equivalent of the 5033046040. Both parts share identical electrical and mechanical specifications within the SlimStack 503304 series. The primary distinction is product status: the 5033046040 is obsolete while the 5033046042 remains in active production.

For new designs and ongoing production requirements, the 5033046042 is the appropriate selection. This part maintains full compatibility with existing mating connectors and PCB layouts designed for the 5033046040. The active product status ensures continued availability and supply chain stability.

The packaging difference—bulk versus tape and reel format—reflects manufacturing and handling preferences but does not affect electrical or mechanical performance. Selection between these formats should be based on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can the 5033046042 directly replace the 5033046040 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same connector type, position count, pitch, mounting configuration, contact finish, and board height. Direct substitution is valid for all applications.

Q: Why is the 5033046040 listed as obsolete?

A: Product obsolescence reflects Molex's manufacturing and support decisions. The 5033046042 remains in active production and serves the same functional purpose, making it the recommended alternative for ongoing supply.

Q: Does packaging format affect connector performance?

A: No. The difference between bulk and tape & reel packaging is a logistics and assembly consideration only. Both formats contain identical connector components with identical electrical and mechanical properties.

Q: Are there compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance, identical moisture sensitivity levels, and equivalent regulatory classifications (ECCN, HTSUS codes).

Q: What parameters must match for a part to be considered a true substitute?

A: Critical parameters include connector type, position count, pitch, row configuration, mounting technology, contact material and finish thickness, stacking height, and series designation. All of these parameters are identical between the 5033046040 and 5033046042.
