Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1064H is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle with female sockets in high-density configuration
• Position Count & Layout: 64 positions in 4×16 arrangement
• Pitch & Spacing: 0.100" (2.54mm) center-to-center spacing
• Mounting Configuration: Through-hole, right-angle orientation
• Termination Method: Solder attachment to PCB
• Contact Material & Finish: Gold plating at specified thickness
• Series Compatibility: HPC™ series designation

The substitute part 50003-1064HLF meets all these criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1064HLF is the direct functional equivalent of the 50003-1064H with two significant advantages:

Product Status: The 50003-1064HLF maintains active production status, ensuring continued availability and manufacturer support. The 50003-1064H is obsolete and subject to supply discontinuation.

Regulatory Compliance: The 50003-1064HLF is RoHS compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. The 50003-1064H is RoHS non-compliant and may face restrictions in new designs or procurement.

Both parts share identical electrical and mechanical specifications, including connector configuration, pitch, mounting method, and contact characteristics. Selection of the 50003-1064HLF is appropriate for applications requiring current product availability and regulatory compliance without design modification.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1064H and 50003-1064HLF mechanically interchangeable?

A: Yes. Both connectors feature identical 64-position high-density configuration, 0.100" pitch, through-hole right-angle mounting, and solder termination. They are mechanically and electrically interchangeable without PCB redesign.

Q: What does the "LF" suffix in 50003-1064HLF indicate?

A: The "LF" designation indicates lead-free construction and RoHS compliance. This is the primary distinction between the obsolete 50003-1064H and the active 50003-1064HLF.

Q: Can I use the 50003-1064HLF as a direct replacement in existing assemblies designed for the 50003-1064H?

A: Yes. The 50003-1064HLF is a direct substitute with identical form, fit, and function. No circuit modifications or PCB layout changes are required.

Q: Why is the 50003-1064H classified as obsolete?

A: Amphenol ICC has transitioned to RoHS-compliant versions of this connector family. The 50003-1064HLF represents the current active product line for this connector type.

Q: Are there any performance differences between these two parts?

A: No. Both parts maintain identical electrical performance, contact finish specifications, and mechanical tolerances. The difference is regulatory compliance status and product lifecycle stage.
