Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1100H is determined by strict alignment with the following electrical and mechanical parameters:

• Connector Type & Style: Must be receptacle with female sockets in high-density configuration
• Position Count & Layout: Must maintain 100 positions in 4-row by 25-column arrangement
• Pitch Specification: Must match 0.100" (2.54mm) center-to-center spacing
• Mounting Configuration: Must support through-hole, right-angle PCB mounting
• Termination Method: Must use solder termination
• Contact Properties: Must feature gold plating at 30.0µin (0.76µm) thickness
• Series Compatibility: Must belong to the HPC™ series family

The substitute part identified below meets all these criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC 50003-1100HLF is the direct substitute for the obsolete 50003-1100H. Both connectors share identical electrical and mechanical specifications across all critical parameters: 100-position high-density configuration, 0.100" pitch, through-hole right-angle mounting, solder termination, and gold contact finish.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 50003-1100HLF maintains active product status with current manufacturing support and availability. Additionally, the 50003-1100HLF is RoHS compliant, whereas the 50003-1100H is RoHS non-compliant. Both parts carry identical export classification (EAR99) and tariff codes (8536.69.4040).

For new designs or ongoing production requiring this connector type, the 50003-1100HLF is the appropriate selection due to its active status and regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1100H and 50003-1100HLF mechanically interchangeable?

A: Yes. Both connectors feature identical mechanical specifications: 100 positions arranged in 4 rows by 25 columns, 0.100" pitch, through-hole right-angle mounting, and solder termination. They are mechanically and electrically interchangeable at the PCB interface level.

Q: What is the significance of the "LF" suffix in the 50003-1100HLF part number?

A: The "LF" designation indicates lead-free compliance, which correlates with the RoHS compliant status of this variant. The 50003-1100H does not carry this designation and is RoHS non-compliant.

Q: Can I use the 50003-1100HLF as a direct replacement in existing assemblies designed for the 50003-1100H?

A: Yes. The 50003-1100HLF is a direct substitute with identical form, fit, and function. No design modifications or PCB layout changes are required for substitution.

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

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The 50003-1100HLF represents the current active equivalent within the HPC™ series family.

Q: Are there any differences in contact finish or plating specifications between these parts?

A: No. Both connectors feature gold contact finish at 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and contact reliability.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 50003-1100H and 50003-1100HLF carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage or handling.
