50003-1220E Equivalent & Substitute Parts

Part Overview

The 50003-1220E is a 220-position high-density backplane connector receptacle manufactured by Amphenol ICC (FCI). This through-hole, right-angle mounted connector features female sockets with gold-plated contacts and is designed for PCB applications requiring high-density interconnection. The part is currently classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50003-1220E is determined by strict equivalence across the following parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Total position count (220 positions)
• High-density connector style classification
• Contact pitch (0.100" / 2.54mm)
• Physical configuration (4 rows, 55 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact material and finish (Gold plating)
• Series designation (HPC™)

The 50003-1220ELF qualifies as a direct substitute based on complete alignment with all these parameters. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1220ELF is the direct active equivalent for the obsolete 50003-1220E. Both parts share identical electrical and mechanical specifications, ensuring functional interchangeability in PCB applications.

The 50003-1220ELF offers two significant advantages:

• Active product status ensures ongoing availability and manufacturer support
• RoHS compliance certification meets current environmental and regulatory requirements, whereas the 50003-1220E is RoHS non-compliant

For new designs or system refreshes, the 50003-1220ELF is the appropriate selection. For legacy systems currently using the 50003-1220E, the 50003-1220ELF provides a compliant replacement without requiring PCB redesign or connector interface modifications.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1220E and 50003-1220ELF mechanically interchangeable?

A: Yes. Both parts are identical in physical dimensions, mounting configuration, and contact arrangement. The 4×55 position layout, 0.100" pitch, through-hole right-angle mounting, and solder termination are identical across both parts.

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

A: The primary differences are product status and RoHS compliance. The 50003-1220E is obsolete and RoHS non-compliant. The 50003-1220ELF is an active product with RoHS compliance certification. All electrical and mechanical parameters are equivalent.

Q: Can I use the 50003-1220ELF as a direct replacement in existing assemblies?

A: Yes. The 50003-1220ELF is a direct substitute with no design or assembly modifications required. It maintains the same contact pitch, position count, mounting method, and termination type.

Q: Why does the part number include "ELF" in the suffix?

A: The "ELF" suffix indicates RoHS compliance and active product status. This distinguishes it from the obsolete non-compliant version.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical contact finish (gold plating at 30.0µin), moisture sensitivity rating (MSL 1), and export classification (EAR99). Electrical performance is equivalent.
