50003-1280E Equivalent & Substitute Parts

Part Overview

The 50003-1280E is a 280-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 models essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1280E is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (280 positions)
• Connector style classification (High Density HPC)
• Pitch specification (0.100" / 2.54mm)
• Physical configuration (4 rows, 70 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact material and finish (Gold plating)

The 50003-1280ELF meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and compliance certification, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1280ELF is the direct active equivalent of the obsolete 50003-1280E. Both parts share identical electrical and mechanical specifications, including connector configuration, pitch, mounting method, and contact characteristics.

The 50003-1280ELF offers two significant advantages:

1. Active product status ensures ongoing availability and manufacturer support
2. RoHS compliance certification meets current environmental and regulatory requirements

For new designs or system replacements, the 50003-1280ELF is the appropriate selection. For legacy systems currently using the 50003-1280E, the 50003-1280ELF provides direct functional compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1280ELF be used as a direct replacement for the 50003-1280E?

A: Yes. Both parts are mechanically and electrically identical. The 50003-1280ELF is the active production equivalent with RoHS compliance certification.

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

A: The 50003-1280E is obsolete and RoHS non-compliant. The 50003-1280ELF is the active equivalent with RoHS compliance. All connector specifications, dimensions, and electrical characteristics are identical.

Q: Are there any compatibility concerns when substituting the 50003-1280ELF for the 50003-1280E?

A: No compatibility concerns exist. The parts are functionally equivalent and share identical pitch, position count, mounting configuration, and contact specifications.

Q: Does the RoHS compliance difference affect connector performance?

A: RoHS compliance reflects material composition and environmental standards, not connector performance. Both parts deliver identical electrical and mechanical function.

Q: What is the position count and configuration of these connectors?

A: Both connectors feature 280 positions arranged in 4 rows and 70 columns with 0.100" (2.54mm) pitch spacing.
