Key Parameters

Substitute Part Grouping Explanation

Substitution for the 51940-010 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets and blade sockets
• Number of positions: 31
• Pitch: 0.100" (2.54mm)
• Number of rows: 4
• Contact layout: 24 signal, 7 power
• Mounting type: Through hole
• Termination method: Press-fit, solder
• Contact finish: Gold or Gold, GXT™
• Contact finish thickness: 30.0µin (0.76µm)
• Color: Black
• Material flammability rating: UL94 V-0
• Operating temperature range: -20°C ~ 105°C
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 51940-010LF meets all these parameters and is therefore electrically and mechanically equivalent to the main part number.

Parameter Comparison

Engineering Selection Recommendations

The 51940-010LF is the direct substitute for the obsolete 51940-010. Both parts are electrically and mechanically identical across all specified parameters.

The 51940-010LF offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS compliance meets current environmental and regulatory requirements
• Tray packaging provides standard handling and storage for production environments

The 51940-010 is no longer in active production. Selection of the 51940-010LF is appropriate for new designs and replacement applications where the 51940-010 was previously specified.
