Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50004-1344E is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets
• Connector style: High density (HPC series)
• Number of positions: 344
• Pitch: 0.100" (2.54mm)
• Row and column configuration: 4 rows × 86 columns
• Mounting type: Through hole, right angle
• Termination method: Solder
• Contact finish: Gold at 30.0µin thickness
• Mating guide feature: Present

The 50004-1344ELF meets all these criteria and represents a direct functional equivalent. The primary distinction lies in product status and regulatory compliance, not in electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 50004-1344ELF is the direct equivalent for the obsolete 50004-1344E. Both parts share identical electrical and mechanical specifications across all provided parameters. The 50004-1344ELF is currently in active production status with 897 units available in stock, compared to the 649 units of the obsolete variant.

For new designs and ongoing system support, the 50004-1344ELF is the appropriate selection. This part carries RoHS compliance certification, whereas the original 50004-1344E does not. Both parts maintain the same MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Are the 50004-1344E and 50004-1344ELF mechanically interchangeable?

A: Yes. Both parts feature identical connector geometry, pitch, mounting configuration, and contact layout. They are direct mechanical equivalents suitable for PCB mounting in identical footprints.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 50004-1344E is obsolete and RoHS non-compliant. The 50004-1344ELF is active production and RoHS compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 50004-1344ELF as a replacement in existing assemblies designed for the 50004-1344E?

A: Yes. The parts are functionally and mechanically equivalent. The 50004-1344ELF can be used as a direct replacement without design modifications.

Q: What does the "LF" suffix in 50004-1344ELF indicate?

A: The "LF" suffix typically indicates lead-free or RoHS-compliant material composition in Amphenol ICC part numbering conventions.

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

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

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints. These connectors can be stored and handled without special moisture control measures.
