Amphenol ICC 50003-1100F High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1100F is a 100-position high-density backplane receptacle connector featuring female sockets configured for through-hole, right-angle mounting on printed circuit boards. This connector is part of the HPC™ series and utilizes a 0.100" (2.54mm) pitch arrangement across 4 rows and 25 columns. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1100F is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Connector style classification (High Density)
• Position count (100 positions)
• Pitch specification (0.100" / 2.54mm)
• Physical configuration (4 rows × 25 columns)
• Mounting orientation (Through Hole, Right Angle)
• Termination method (Solder)
• Contact finish specification (Gold plating)
• Series compatibility (HPC™)

The 50003-1100FLF meets all these criteria and qualifies as a direct functional substitute. The primary distinction between these parts is product status and regulatory compliance, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1100FLF is the direct equivalent substitute for the 50003-1100F. Both parts are manufactured by Amphenol ICC within the HPC™ series and share identical electrical and mechanical specifications across all critical parameters.

Selection between these parts should be based on the following factors:

For new designs or applications requiring regulatory compliance, the 50003-1100FLF is the appropriate choice due to its active product status and RoHS compliance certification.

For legacy system maintenance or applications where the original 50003-1100F specification is mandated, the 50003-1100F remains available in inventory (950 units) despite its obsolete classification.

The 50003-1100FLF maintains full backward compatibility with existing PCB layouts, mating connectors, and system architectures designed for the 50003-1100F, as all physical and electrical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1100FLF be used as a direct replacement for the 50003-1100F in existing assemblies?

A: Yes. The 50003-1100FLF is a direct functional equivalent. All electrical and mechanical parameters are identical, including position count, pitch, mounting configuration, and contact specifications. PCB layouts and mating connectors require no modification.

Q: What is the difference between the 50003-1100F and 50003-1100FLF?

A: The parts are electrically and mechanically identical. The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. compliant). The "FLF" designation indicates the RoHS-compliant variant.

Q: Are there any compatibility concerns when substituting the 50003-1100FLF for the 50003-1100F?

A: No compatibility concerns exist. Both parts use the same HPC™ series platform, identical 0.100" pitch, 100-position configuration, and gold-plated contacts. Mating connectors, PCB footprints, and electrical performance are fully compatible.

Q: Why is the 50003-1100F classified as obsolete?

A: The 50003-1100F has been superseded by the RoHS-compliant 50003-1100FLF variant. Amphenol ICC has transitioned production to the compliant version to meet current regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both the 50003-1100F and 50003-1100FLF carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are these connectors suitable for through-hole PCB assembly?

A: Yes. Both parts are specified for through-hole, right-angle mounting and are terminated via solder. They are compatible with standard PCB assembly processes.
