Key Parameters

Substitute Part Grouping Explanation

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

• Connector type and style (Receptacle, Female Sockets; High Density)
• Number of positions (440)
• Pitch specification (0.100" / 2.54mm)
• Physical configuration (4 rows × 110 columns)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact finish and thickness (Gold, 30.0µin)
• Series compatibility (HPC™)

The 50004-1440FLF qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and compliance certification, not functional or dimensional parameters.

Parameter Comparison

Engineering Selection Recommendations

The 50004-1440FLF is the direct functional equivalent of the 50004-1440F. Both parts share identical electrical and mechanical specifications, including connector configuration, pitch, mounting method, and contact characteristics.

The 50004-1440FLF is currently in active production status, whereas the 50004-1440F is obsolete. For new designs or ongoing procurement, the 50004-1440FLF is the appropriate selection.

The 50004-1440FLF carries RoHS compliance certification, whereas the 50004-1440F does not. Systems requiring RoHS-compliant components should specify the 50004-1440FLF.

Both parts maintain identical moisture sensitivity levels and are suitable for standard PCB assembly environments.

Frequently Asked Questions (FAQ)

Q: Can the 50004-1440FLF be used as a direct replacement for the 50004-1440F in existing designs?

A: Yes. The 50004-1440FLF is electrically and mechanically identical to the 50004-1440F. All connector specifications, including position count, pitch, mounting configuration, and contact finish, are equivalent. No design modifications are required.

Q: What is the primary difference between these two parts?

A: The 50004-1440F is obsolete and RoHS non-compliant. The 50004-1440FLF is in active production and RoHS compliant. The functional specifications are identical.

Q: Are there any compatibility concerns when substituting the 50004-1440FLF for the 50004-1440F?

A: No compatibility concerns exist. Both parts are from the same HPC™ series, share the same base product number (50004), and have identical physical and electrical characteristics. Mating connectors and PCB footprints designed for the 50004-1440F will function with the 50004-1440FLF without modification.

Q: Does the RoHS compliance difference affect performance?

A: RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both parts perform identically in circuit applications. RoHS compliance is a regulatory and supply chain consideration.

Q: What is the current availability status of these parts?

A: The 50004-1440F is obsolete with limited inventory (1111 pcs reported). The 50004-1440FLF is in active production with current inventory (700 pcs reported). For new procurement, the 50004-1440FLF should be specified.
