Key Parameters

Substitute Part Grouping Explanation

The 51940-110LF qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type matches: Receptacle with female sockets and blade sockets
• Position count identical: 15 positions
• Pitch specification identical: 0.100" (2.54mm)
• Row configuration identical: 4 rows
• Contact layout identical: 8 Signal, 7 Power
• Mounting method identical: Through Hole with solder termination
• Physical features identical: Board Lock and Guide Pin
• Contact finish specification identical: Gold plating at 30.0µin thickness
• Thermal operating range identical: -20°C to 105°C
• Flammability rating identical: UL94 V-0

The primary distinction between these parts is product status and regulatory compliance, not functional or mechanical capability.

Parameter Comparison

Engineering Selection Recommendations

The 51940-110LF is the appropriate selection for new designs and ongoing procurement. This part maintains identical electrical and mechanical specifications to the obsolete 51940-110 while offering active product status and RoHS compliance. The LF designation indicates lead-free termination processing, aligning with current environmental and regulatory standards. For applications requiring RoHS non-compliant components, the original 51940-110 remains functionally equivalent but is subject to obsolescence constraints and limited availability.

Frequently Asked Questions (FAQ)

Q: Are the 51940-110 and 51940-110LF mechanically interchangeable?

A: Yes. Both connectors share identical physical dimensions, pitch, row configuration, mounting method, and contact layout. PCB footprints and mating interfaces are identical.

Q: What is the functional difference between these parts?

A: There is no functional difference. Both parts provide identical electrical performance, contact configuration, and thermal operating range. The differences are limited to product lifecycle status and RoHS compliance.

Q: Why does the 51940-110LF have an "LF" suffix?

A: The LF designation indicates lead-free termination processing, reflecting compliance with RoHS directives and modern manufacturing standards.

Q: Can I use 51940-110LF in place of 51940-110 in existing designs?

A: Yes. The 51940-110LF is a direct functional and mechanical substitute. No design modifications are required.

Q: What is the packaging difference?

A: The 51940-110 packaging is not specified in available data. The 51940-110LF is supplied in Tray packaging. Confirm packaging requirements with your procurement specification.

Q: Are there any compliance considerations for substitution?

A: The 51940-110LF is RoHS Compliant and REACH Affected. If your application requires RoHS non-compliant components, the original 51940-110 remains available but is obsolete. Verify compliance requirements with your design documentation.
