Amphenol ICC 50003-1164E High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1164E is a 164-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 mounting applications requiring high-density interconnection in a 4-row by 41-column layout with 0.100" (2.54mm) pitch spacing.

The 50003-1164E carries an obsolete product status, making identification of active equivalent parts essential for ongoing system support, maintenance, and new design implementations. The primary substitute maintains identical electrical and mechanical specifications while offering current product availability and improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50003-1164E is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 164-position receptacle with female sockets
• Mechanical Layout: 4 rows × 41 columns at 0.100" (2.54mm) pitch
• Mounting Orientation: Through-hole, right-angle configuration
• Electrical Interface: Solder termination with gold-plated contacts at 30.0µin thickness
• Physical Features: Mating guide inclusion

The substitute part 50003-1164ELF maintains complete equivalence across all specified electrical and mechanical parameters. The primary distinction between the main part and its substitute lies in product lifecycle status and regulatory compliance, not in form, fit, or function.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1164ELF is the direct active equivalent for the obsolete 50003-1164E. Selection between these parts is determined by application requirements and regulatory constraints:

Use 50003-1164ELF when:

• New designs require RoHS compliance
• System procurement mandates active product status
• Long-term supply chain continuity is required
• Regulatory frameworks require compliant component sourcing

Use 50003-1164E when:

• Legacy system maintenance requires exact original part matching
• Existing inventory stock is available and acceptable
• Non-compliant component status does not conflict with application requirements

Both parts are manufactured by Amphenol ICC (FCI) and maintain identical form, fit, and function across all specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1164E and 50003-1164ELF mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through-hole, right-angle), position count (164), row/column configuration (4×41), and pitch spacing (0.100"). PCB layout and mating interface compatibility are identical.

Q: What is the significance of the "ELF" suffix in the 50003-1164ELF part number?

A: The "ELF" designation indicates RoHS compliance status. The 50003-1164ELF meets RoHS regulatory requirements, while the 50003-1164E does not. All other specifications remain equivalent.

Q: Can I use the 50003-1164ELF as a direct replacement in existing assemblies designed for the 50003-1164E?

A: Yes. The 50003-1164ELF provides complete functional and mechanical equivalence. No PCB redesign, retooling, or assembly process modification is required.

Q: Are there any electrical performance differences between these two connectors?

A: No. Both parts feature identical contact finish (gold at 30.0µin thickness), solder termination, and mating guide features. Electrical performance characteristics are equivalent.

Q: What is the current inventory status for these parts?

A: The 50003-1164E has 956 pieces in stock (obsolete status). The 50003-1164ELF has 875 pieces in stock (active status). Availability may vary by distributor and region.

Q: Are both parts classified under the same HTSUS and ECCN codes?

A: Yes. Both the 50003-1164E and 50003-1164ELF share identical HTSUS code (8536.69.4040) and ECCN classification (EAR99).
