• Connector Type: Receptacle with center strip contacts
• Number of Positions: 60 positions
• Pitch: 0.016" (0.40mm)
• Number of Rows: 2 rows
• Mounting Type: Surface mount
• Contact Finish: Gold plating
• Height Above Board: 0.102" (2.60mm)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The Molex 0546840604 meets all these critical parameters and is classified as an active product with current manufacturing support. This part belongs to the SlimStack 54684 series and maintains full electrical and mechanical compatibility with the obsolete 0544770608.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0546840604 is the manufacturer-recommended substitute for the obsolete 0544770608. Both parts maintain identical electrical and mechanical specifications for the critical connector parameters: 60 positions, 0.016" pitch, 2-row configuration, surface mount design, and gold contact finish.

The 0546840604 offers the advantage of active product status with current manufacturing support and availability. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The contact finish thickness differs between the two parts (10.0µin versus 4.00µin), but both maintain gold plating suitable for the connector application. The substitute part supports both 4.6mm and 4mm mated stacking heights, providing additional flexibility compared to the main part's 4mm specification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0546840604 be used as a direct replacement for the 0544770608?
