Substitute Part Grouping Explanation

Substitution of the 50003-1260H is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle, Female Sockets
• Connector Style: High Density (HDC, HDI, HPC)
• Number of Positions: 260
• Pitch: 0.100" (2.54mm)
• Row and Column Configuration: 4 rows × 65 columns
• Mounting Type: Through Hole, Right Angle
• Termination Method: Solder
• Contact Finish: Gold at 30.0µin (0.76µm)
• Series Compatibility: HPC™

The primary substitute identified is the 50003-1260HLF, which maintains identical electrical and mechanical specifications while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1260HLF is the direct functional equivalent of the 50003-1260H. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, and contact finish specifications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 50003-1260H is classified as obsolete, while the 50003-1260HLF maintains active product status. Additionally, the 50003-1260HLF is RoHS compliant, whereas the 50003-1260H is RoHS non-compliant. For applications requiring regulatory compliance with current environmental standards, the 50003-1260HLF is the appropriate selection. For legacy system maintenance where the original non-compliant specification is required, the 50003-1260H remains available in current inventory.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1260H and 50003-1260HLF mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including mounting type (through-hole, right-angle), PCB footprint dimensions (4 rows × 65 columns at 0.100" pitch), and connector body configuration. Direct substitution is mechanically feasible.

Q: What is the significance of the "LF" suffix in the 50003-1260HLF part number?

A: The "LF" designation indicates lead-free and RoHS compliance. This reflects the manufacturing process and material composition changes implemented to meet current environmental regulations.

Q: Can the 50003-1260HLF be used as a drop-in replacement for the 50003-1260H?

A: From an electrical and mechanical standpoint, yes. The 50003-1260HLF provides identical performance characteristics. However, design documentation and compliance requirements should be reviewed to ensure the RoHS-compliant variant aligns with system specifications.

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

A: The 50003-1260H (obsolete) has 729 units in stock. The 50003-1260HLF (active) has 806 units in stock. The active status of the 50003-1260HLF ensures continued availability and support.

Q: Are there any electrical performance differences between these connectors?

A: No. Both parts maintain identical contact finish specifications (gold at 30.0µin thickness), termination method (solder), and feature set (mating guide). Electrical performance is equivalent.
