Amphenol ICC 50003-1284E High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1284E is a 284-position high-density backplane connector featuring female sockets in a through-hole, right-angle configuration. This receptacle connector is part of the HPC™ series and is designed for PCB-mounted applications requiring high-density interconnection. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1284E is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets, High Density)
• Position count and configuration (284 positions, 4 rows × 71 columns)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact finish and thickness (Gold, 30.0µin)
• Series compatibility (HPC™)

The substitute part 50003-1284ELF meets all these criteria and maintains full electrical and mechanical compatibility with the original part number.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1284ELF is the direct functional equivalent of the 50003-1284E. Both parts share identical electrical and mechanical specifications, including connector configuration, pitch, mounting method, and contact characteristics.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The original 50003-1284E is obsolete and does not meet RoHS compliance requirements. The 50003-1284ELF is an active product that maintains full compatibility while meeting current RoHS standards.

For new designs and ongoing system support where component availability is required, the 50003-1284ELF is the appropriate selection. For legacy systems currently using the 50003-1284E, direct substitution is mechanically and electrically valid.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1284E and 50003-1284ELF mechanically interchangeable?

A: Yes. Both parts feature identical mounting configurations (through-hole, right-angle), position counts (284), and pitch specifications (0.100"). They mount identically on PCBs and mate with the same complementary connectors.

Q: What is the difference between these part numbers?

A: The 50003-1284ELF is the active production equivalent of the obsolete 50003-1284E. The primary differences are product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant). All electrical and mechanical parameters are identical.

Q: Can I use the 50003-1284ELF as a replacement in existing assemblies designed for the 50003-1284E?

A: Yes. The 50003-1284ELF provides direct substitution. No design modifications or PCB layout changes are required.

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

A: The "ELF" suffix indicates RoHS compliance and active production status within Amphenol ICC's product nomenclature. The base part number 50003-1284 remains consistent across both versions.

Q: Are there any lead time or availability differences between these parts?

A: The 50003-1284E is obsolete and availability is limited to existing inventory. The 50003-1284ELF is an active product with standard lead times and ongoing manufacturing availability.

Q: What certifications apply to the 50003-1284ELF?

A: The 50003-1284ELF meets RoHS compliance requirements. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and share identical ECCN (EAR99) and HTSUS (8536.69.4040) designations.
