Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50003-1168E is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 168 positions (non-negotiable)
• Pitch Specification: 0.100" (2.54mm) center-to-center spacing
• Connector Configuration: 4 rows × 42 columns
• Mounting Orientation: Through-hole, right-angle geometry
• Contact Type: Female sockets with gold finish
• Termination Method: Solder attachment
• Series Compatibility: HPC™ series

The 50003-1168ELF meets all these criteria as a direct functional equivalent. The primary distinction is product status: the original part is obsolete, while the substitute is active in production.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1168ELF is the direct substitute for the 50003-1168E. Both parts are manufactured by Amphenol ICC (FCI) within the HPC™ series and share identical electrical and mechanical specifications across all critical parameters.

The 50003-1168ELF offers two additional advantages:

• Product Status: Active production status ensures ongoing availability and supply chain reliability.
• RoHS Compliance: The substitute meets RoHS requirements, whereas the original part does not. This distinction is significant for applications subject to environmental regulations or customer compliance mandates.

For new designs, field replacements, and production continuity, the 50003-1168ELF is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1168E and 50003-1168ELF mechanically interchangeable?

A: Yes. Both parts share identical mounting geometry, pitch, position count, and row/column configuration. They are direct mechanical equivalents.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The 50003-1168E is obsolete and RoHS non-compliant. The 50003-1168ELF is active in production and RoHS compliant.

Q: Can I use the 50003-1168ELF as a replacement in existing designs?

A: Yes. The substitute maintains full electrical and mechanical compatibility with the original part specification.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical characteristics. Both parts deliver identical electrical performance.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold-plated contacts with a thickness of 30.0µin (0.76µm), ensuring consistent contact resistance and reliability.

Q: Are there any packaging or lead time considerations?

A: The 50003-1168ELF is actively manufactured and stocked. The 50003-1168E is obsolete and may have limited availability. For new procurement, the 50003-1168ELF is the recommended choice.
