Substitute Part Grouping Explanation

Substitution eligibility for the 51940-084 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets and blade sockets
• Position count: 19 positions with 13 positions loaded
• Pitch spacing: 0.100" (2.54mm)
• Row configuration: 4 rows
• Contact layout: 12 signal, 7 power
• Mounting method: Through hole with solder termination
• Contact finish specification: Gold or Gold, GXT™ at 30.0µin thickness
• Physical color: Black
• Flammability rating: UL94 V-0
• Operating temperature range: -20°C to 105°C
• Series designation: PwrBlade®

The substitute part 51940-084LF meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

The 51940-084LF is the direct substitute for the obsolete 51940-084. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance.

The 51940-084LF is classified as active and carries RoHS compliance certification, whereas the 51940-084 is obsolete and RoHS non-compliant. For new designs or ongoing production requiring compliance with current environmental regulations, the 51940-084LF is the appropriate selection. The 51940-084LF is supplied in tray packaging, which is standard for production quantities.
