Key Parameters

Substitute Part Grouping Explanation

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

• Connector type and style (Receptacle, Female Sockets; High Density)
• Position count and configuration (440 positions; 4 rows × 110 columns)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole, Right Angle)
• Termination type (Solder)
• Contact finish specification (Gold plating)
• Series designation (HPC™)
• Base product number (50004)

Parts meeting all these criteria are considered direct functional equivalents. Variations in product status or compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 50004-1440HLF serves as the direct substitute for the obsolete 50004-1440H. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction is product status and regulatory compliance:

The 50004-1440H is classified as obsolete and carries RoHS non-compliant status. The 50004-1440HLF is an active product with RoHS compliance certification, making it the preferred selection for new designs and ongoing production requirements. Both parts share identical connector specifications, contact configurations, and termination methods, ensuring seamless integration into existing PCB layouts and mating interfaces.

Frequently Asked Questions (FAQ)

Q: Are the 50004-1440H and 50004-1440HLF mechanically interchangeable?

A: Yes. Both parts feature identical mounting configurations (through-hole, right-angle), position counts (440), pitch spacing (0.100"), and row/column arrangements (4 × 110). They are direct mechanical equivalents.

Q: What is the significance of the "LF" designation in the 50004-1440HLF part number?

A: The "LF" suffix indicates lead-free and RoHS compliance. This reflects the manufacturing process and material composition changes, not the connector's functional or mechanical characteristics.

Q: Can the 50004-1440HLF be used as a replacement in legacy systems designed for the 50004-1440H?

A: Yes. The electrical and mechanical specifications are identical. The substitute part maintains full compatibility with existing mating connectors, PCB footprints, and system interfaces.

Q: Are there any differences in contact finish or plating between these parts?

A: No. Both parts specify gold contact finish at 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and reliability.

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

A: Both the 50004-1440H and 50004-1440HLF carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
