Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50003-1140H is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle with female sockets in high-density configuration
• Position Count & Layout: Exactly 140 positions in 4×35 arrangement
• Pitch & Spacing: 0.100" (2.54mm) pitch maintained
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Contact Specifications: Gold finish at 30.0µin thickness
• Series Compatibility: HPC™ series designation

The 50003-1140HLF meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and compliance certification, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1140HLF is the direct functional equivalent of the 50003-1140H. Both parts share identical electrical and mechanical specifications across all connector parameters. Selection between these parts should be based on the following criteria:

For New Designs: The 50003-1140HLF is the appropriate choice due to active product status and RoHS compliance certification. This ensures long-term availability and regulatory alignment.

For Legacy System Support: The 50003-1140H remains available in inventory (1027 units) for applications requiring exact original component matching or where RoHS compliance is not a requirement.

For Compliance-Driven Applications: The 50003-1140HLF meets RoHS requirements, making it suitable for applications subject to environmental and regulatory standards.

Both parts are manufactured by Amphenol ICC (FCI) under the HPC™ series and maintain identical connector geometry, contact configuration, and termination specifications.

Frequently Asked Questions (FAQ)

Q: Can the 50003-1140HLF be used as a direct replacement for the 50003-1140H?
