Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50003-1040E is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle, Female Sockets; High Density (HDC, HDI, HPC)
• Position Configuration: 40 positions arranged in 4 rows × 10 columns
• Pitch & Spacing: 0.100" (2.54mm) standard pitch
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Contact Specifications: Gold plating at 30.0µin (0.76µm) thickness with mating guide feature
• Series Designation: HPC™ series

The 50003-1040ELF meets all these criteria and represents the active production equivalent within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1040ELF is the direct functional equivalent of the 50003-1040E. Both parts share identical electrical and mechanical specifications within the HPC™ series. The primary distinction is product status and regulatory compliance:

• 50003-1040E: Obsolete status with RoHS non-compliant designation
• 50003-1040ELF: Active production status with RoHS Compliant certification

For new designs or ongoing procurement requiring current-generation components, the 50003-1040ELF is the appropriate selection. Both parts maintain identical contact specifications, pitch, position count, and mounting configuration, ensuring direct interchangeability at the PCB interface level.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1040E and 50003-1040ELF mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through-hole, right-angle), position configuration (40 positions in 4×10 arrangement), and pitch (0.100"). They are mechanically interchangeable on PCB layouts designed for either part number.

Q: What is the significance of the "ELF" suffix in the 50003-1040ELF part number?

A: The "ELF" suffix indicates RoHS Compliant status and active production designation within the Amphenol ICC product line. This distinguishes it from the obsolete 50003-1040E variant.

Q: Can the 50003-1040ELF be used as a direct replacement in legacy systems designed for the 50003-1040E?

A: Yes. The electrical and mechanical specifications are identical. The 50003-1040ELF provides a direct substitution path for systems requiring component refresh or redesign.

Q: Are there any differences in contact finish or plating between these two part numbers?

A: No. Both parts feature gold-plated contacts with identical finish thickness of 30.0µin (0.76µm).

Q: What is the moisture sensitivity level for both parts?

A: Both the 50003-1040E and 50003-1040ELF carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
