Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50004-1440E is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (440 positions)
• High-density connector style classification
• Contact pitch (0.100" / 2.54mm)
• Physical configuration (4 rows, 110 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact material and finish specifications (Gold plating)

The 50004-1440ELF qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction between these parts is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 50004-1440ELF is the direct functional equivalent of the 50004-1440E. Selection between these parts should be based on the following criteria:

For new designs and ongoing procurement: The 50004-1440ELF is the appropriate choice. This part maintains active product status with Amphenol ICC (FCI) and carries RoHS compliance certification, meeting current regulatory requirements for electronic component manufacturing and supply.

For legacy system maintenance: The 50004-1440E remains available in inventory (1040 pcs) for applications where existing designs are locked to the obsolete part number. However, migration to the 50004-1440ELF is recommended where design constraints permit, as the obsolete status indicates discontinued manufacturing support.

Both parts share identical electrical and mechanical specifications, ensuring direct interchangeability at the connector interface level. The "ELF" suffix designation in the 50004-1440ELF indicates lead-free and RoHS-compliant manufacturing, representing the primary technical distinction between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can the 50004-1440ELF be used as a direct replacement for the 50004-1440E in existing assemblies?

A: Yes. Both parts are mechanically and electrically identical across all specified parameters. The 50004-1440ELF can be substituted without modification to PCB layouts, mating connectors, or assembly procedures.

Q: What does the "ELF" suffix indicate?

A: The "ELF" designation indicates lead-free (Pb-free) and RoHS-compliant manufacturing. This reflects the part's compliance with environmental and hazardous substance regulations.

Q: Why is the 50004-1440E classified as obsolete?

A: Obsolete status indicates that Amphenol ICC (FCI) has discontinued active manufacturing and support for this part number. The 50004-1440ELF represents the current active equivalent.

Q: Are there any differences in contact reliability or performance between these parts?

A: No. Both parts feature identical gold contact finish specifications (30.0µin / 0.76µm) and the same contact material composition. Performance characteristics are equivalent.

Q: What is the significance of the 440-position, 4-row × 110-column configuration?

A: This configuration defines the physical and electrical layout of the connector. Any substitute part must maintain this exact position count and arrangement to ensure compatibility with mating connectors and PCB footprints.

Q: Can these connectors be used interchangeably with other high-density connector styles?

A: No. The HPC™ series designation and 0.100" pitch specification define compatibility within the Amphenol ICC (FCI) high-density connector ecosystem. Connectors from other manufacturers or series may have different mechanical or electrical characteristics.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why is it relevant?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard conditions without special humidity control or desiccant packaging requirements.
