Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1108E is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets; High Density)
• Position count (108 positions)
• Pitch specification (0.100" / 2.54mm)
• Physical configuration (4 rows, 27 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact finish specification (Gold plating)

The substitute part 50003-1108ELF meets all these criteria and is manufactured by the same supplier (Amphenol ICC), ensuring mechanical and electrical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1108ELF is the direct substitute for the obsolete 50003-1108E. Both parts share identical mechanical and electrical specifications, ensuring pin-for-pin compatibility and functional equivalence in PCB designs.

The primary distinction between these parts is product status and regulatory compliance. The 50003-1108E is obsolete and RoHS non-compliant, while the 50003-1108ELF is an active product with RoHS compliance certification. For new designs or systems requiring regulatory compliance with current environmental standards, the 50003-1108ELF is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, the 50003-1108ELF remains mechanically and electrically compatible.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1108ELF be used as a direct replacement for the 50003-1108E?
