Molex 0744410021 SFP+ Receptacle Connector – Equivalent & Substitute Parts

Part Overview

The Molex 0744410021 is a 20-position SFP+ receptacle connector designed for surface mount, right-angle solder termination applications. This connector is part of the Z-Axis Pluggable 74441 series and features a board guide for mechanical stability. The part is currently classified as obsolete, making identification of active equivalent components essential for ongoing production and design continuity. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or board layout modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0744410021 is based on strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

• Connector type: SFP+ (20-position)
• Mounting configuration: Surface mount, right-angle orientation
• Termination: Solder-based connection
• Contact finish: Gold plating at 30.0µin thickness
• Mechanical feature: Board guide integration
• Compliance: ROHS3 certification and MSL 1 rating

The Molex 0744410010 meets all these requirements and is classified as an active product, making it the direct functional equivalent for the obsolete 0744410021.
