Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1180E is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets, High Density)
• Position count and arrangement (180 positions, 4 rows × 45 columns)
• Pitch specification (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Contact finish and thickness (Gold, 30.0µin)
• Mating guide feature presence

The substitute part 50003-1180ELF meets all these criteria and is manufactured by the same supplier within the same HPC™ series, ensuring mechanical and electrical compatibility with applications originally designed for the 50003-1180E.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1180ELF is the direct functional equivalent of the 50003-1180E. Both parts share identical mechanical and electrical specifications across all critical parameters. The primary distinction is product status and regulatory compliance:

The 50003-1180E is obsolete and RoHS non-compliant. The 50003-1180ELF is an active product with RoHS compliance certification. For new designs or systems requiring regulatory compliance with current environmental standards, the 50003-1180ELF is the appropriate selection. For legacy system maintenance where the original part specification must be preserved, the 50003-1180E remains available in current inventory (978 units).

Both parts are manufactured by Amphenol ICC (FCI) within the HPC™ series and are fully interchangeable at the mechanical and electrical interface level.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1180E and 50003-1180ELF mechanically interchangeable?

A: Yes. Both connectors have identical dimensions, pitch, mounting configuration, and contact arrangement. They are direct mechanical equivalents and will fit the same PCB footprint and mating connector.

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

A: The primary differences are product status and RoHS compliance. The 50003-1180E is obsolete and RoHS non-compliant. The 50003-1180ELF is an active product with RoHS compliance. All electrical and mechanical specifications are identical.

Q: Can I use the 50003-1180ELF as a replacement for the 50003-1180E in existing designs?

A: Yes. The 50003-1180ELF is a direct substitute with identical specifications. It is suitable for both new designs and replacement applications in existing systems.

Q: What does the "ELF" suffix in the part number indicate?

A: The "ELF" suffix indicates RoHS compliance and active product status. The base specification (50003-1180) remains unchanged.

Q: Are there any compatibility concerns with mating connectors?

A: No. Both parts feature identical contact geometry, pitch, and mating guide specifications. Any connector designed to mate with the 50003-1180E will mate with the 50003-1180ELF without modification.

Q: What is the current availability of these parts?

A: The 50003-1180E (obsolete) has 978 units in stock. The 50003-1180ELF (active) has 934 units in stock.
