Key Parameters

Substitute Part Grouping Explanation

Substitute components for the PHEC50P-R111LF are identified based on the following critical parameters that must align for functional compatibility:

• Position Count & Row Configuration: 50 positions, 2 rows
• Connector Type: Plug configuration
• Mounting Method: Through hole, right-angle orientation
• Termination Method: Solder connection
• Connector Style: Center strip contacts
• Contact Material: Gold plating
• Mechanical Features: Board lock functionality

The substitute part 1734099-5 (TE Connectivity AMP Connectors) satisfies all these parameters. While classified as a board-to-board connector variant, it maintains electrical and mechanical compatibility with the original PHEC50P-R111LF specification through identical position count, row configuration, mounting type, termination method, and contact characteristics.

• Regulatory Compliance: The 1734099-5 carries RoHS Compliant certification, meeting current environmental and regulatory requirements.
• Electrical & Mechanical Equivalence: All critical parameters—position count, row configuration, mounting type, termination method, and contact characteristics—are identical between the original and substitute.
• Export Classification: Both components share the same ECCN classification (EAR99), maintaining consistent export compliance.
• Packaging Availability: The substitute is supplied in tray packaging with higher inventory availability (2170 pcs) compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the 1734099-5 be used as a direct replacement for PHEC50P-R111LF in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications: 50 positions, 2 rows, through-hole right-angle solder termination, center strip contacts, gold plating, and board lock features. The substitute is functionally equivalent for applications requiring these parameters.

Q: What is the difference between a standard plug connector and a board-to-board plug connector?

A: The 1734099-5 is classified as a board-to-board connector variant, but maintains the same plug configuration and electrical interface as the original PHEC50P-R111LF. The board-to-board designation refers to the connector's design intent rather than a functional limitation. Both are compatible with standard D-Sub receptacle connectors.

Q: Are there packaging differences between the original and substitute?

A: The PHEC50P-R111LF packaging is not specified in the original documentation. The 1734099-5 is supplied in tray packaging. Verify packaging requirements for your specific application and procurement process.

Q: Does the substitute meet current environmental standards?

A: Yes. The 1734099-5 is RoHS Compliant, meeting current environmental regulations. The original PHEC50P-R111LF RoHS status is not specified due to its obsolete status.

Q: Are there any compliance or export restrictions on the substitute?

A: Both the original and substitute components are classified under ECCN EAR99, indicating no specific export restrictions. Verify current export regulations for your jurisdiction and end-use application.

Q: What is the contact finish thickness difference between the parts?

A: The original PHEC50P-R111LF specifies contact finish thickness of 3.94µin (0.10µm). The substitute 1734099-5 specifies flash plating. Both gold finishes provide equivalent electrical performance for solder termination applications.
