Substitute Part Grouping Explanation

Substitution of the 51940-082 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets and blade sockets
• Position count: 62 total positions with 34 positions loaded
• Pitch specification: 0.100" (2.54mm)
• Row configuration: 4 rows
• Mounting method: Through hole
• Termination style: Press-fit and solder capable
• Contact layout distribution: 44 signal and 18 power positions
• Contact finish specification: Gold or Gold, GXT™ at 30.0µin thickness
• Physical color: Black
• Flammability rating: UL94 V-0
• Temperature operating range: -20°C to 105°C

The substitute part 51940-082LF maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 51940-082LF is the direct substitute for the obsolete 51940-082. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, and contact layout.

The primary distinction between these parts is product lifecycle status and compliance posture. The 51940-082LF carries active product status, ensuring ongoing manufacturer support and availability. The 51940-082LF is RoHS compliant and REACH affected, whereas the 51940-082 is RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the 51940-082LF is the appropriate selection. For legacy system maintenance where the original non-compliant specification is mandated, the 51940-082 remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the 51940-082LF be used as a direct replacement for the 51940-082?

A: Yes. Both connectors are electrically and mechanically identical across all specified parameters including position count, pitch, mounting type, termination method, contact layout, and operating temperature range. The primary differences are product status and compliance certifications.

Q: What is the difference between the 51940-082 and 51940-082LF?

A: The 51940-082LF is the active production variant of the 51940-082. The LF designation indicates RoHS compliance and REACH compliance status. The 51940-082 is obsolete and RoHS non-compliant. Packaging differs: the 51940-082 is supplied in bulk, while the 51940-082LF is supplied in trays.

Q: Are there any compatibility concerns when substituting the 51940-082LF for the 51940-082?

A: No compatibility concerns exist. The connectors maintain identical physical dimensions, pin configurations, contact specifications, and electrical ratings. PCB layouts and mating connector designs require no modification.

Q: What is the significance of the "LF" suffix in the part number?

A: The "LF" suffix indicates lead-free and RoHS compliant manufacturing. This designation confirms the part meets current environmental and regulatory requirements for electronic components.

Q: Does the change in packaging from bulk to tray affect functionality?

A: No. Packaging format affects only handling, storage, and logistics. The connector itself remains functionally identical regardless of packaging configuration.
