Amphenol ICC 50003-1040H High Density Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 50003-1040H is a 40-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. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50003-1040H is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Sockets, High Density)
• Number of positions and configuration (40 positions, 4×10 arrangement)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact finish and thickness (Gold, 30.0µin)
• Series compatibility (HPC™)

The substitute part 50003-1040HLF meets all these criteria and is manufactured by the same supplier (Amphenol ICC), ensuring mechanical and electrical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1040HLF is the direct functional equivalent of the 50003-1040H. Both parts share identical mechanical and electrical specifications across all critical parameters. The primary distinction is product lifecycle status: the original part is obsolete, while the substitute is active in production.

The 50003-1040HLF additionally provides RoHS compliance, which addresses regulatory requirements for new designs and systems subject to environmental standards. For applications requiring RoHS non-compliant components, the original 50003-1040H remains available through existing inventory channels, though long-term availability cannot be assured due to its obsolete status.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1040H and 50003-1040HLF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 40 positions, 0.100" pitch, 4×10 configuration, through-hole right-angle mounting, and gold-plated contacts. They are direct mechanical substitutes.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The 50003-1040H is obsolete and RoHS non-compliant. The 50003-1040HLF is active in production and RoHS compliant. All functional and mechanical parameters are identical.

Q: Can I use the 50003-1040HLF in place of the 50003-1040H in existing designs?

A: Yes. The 50003-1040HLF is a direct substitute with identical electrical and mechanical characteristics. No design modifications are required.

Q: Does the RoHS compliance of the 50003-1040HLF affect performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical or mechanical performance. Both parts operate identically within their specified parameters.

Q: What is the pitch specification, and why does it matter for substitution?

A: The pitch is 0.100" (2.54mm), representing the center-to-center distance between adjacent contact positions. Pitch is a critical substitution criterion; parts with different pitches are not interchangeable.

Q: Are there any packaging differences between these parts?

A: Packaging information is not provided in the technical specifications for either part. Consult the manufacturer's datasheet or contact Amphenol ICC directly for packaging details.
