Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50003-1068H is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Connector style classification (High Density HPC™ series)
• Position count and arrangement (68 positions, 4 rows × 17 columns)
• Contact pitch (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Contact finish specification (Gold, 30.0µin thickness)
• Mating guide feature presence

The substitute part 50003-1068HLF maintains identical electrical and mechanical specifications while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 50003-1068HLF serves as the direct substitute for the obsolete 50003-1068H. Both components maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting configuration, and contact finish.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 50003-1068H is classified as obsolete with RoHS non-compliant status, while the 50003-1068HLF maintains active product status with RoHS compliance. For new designs and ongoing system support requiring regulatory adherence, the 50003-1068HLF is the appropriate selection. Both parts share identical MSL classification and are suitable for unlimited moisture exposure conditions.

Frequently Asked Questions (FAQ)

Q: Are the 50003-1068H and 50003-1068HLF mechanically interchangeable?

A: Yes. Both connectors feature identical mechanical specifications: 68 positions arranged in 4 rows × 17 columns, 0.100" pitch, through-hole right-angle mounting, and solder termination. Physical dimensions and mating interfaces are equivalent.

Q: What is the significance of the "LF" suffix in the 50003-1068HLF part number?

A: The "LF" designation indicates lead-free construction, which correlates with the RoHS compliant status of this variant. The 50003-1068H lacks this designation and is RoHS non-compliant.

Q: Can the 50003-1068HLF be used in applications originally designed for the 50003-1068H?

A: Yes. The substitute part maintains all critical electrical and mechanical parameters. Applications requiring RoHS compliance or supporting active product lifecycles should transition to the 50003-1068HLF.

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

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

Q: What is the moisture sensitivity classification for these connectors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.
