Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PHEC50R-R110LF are identified based on the following critical parameters that must remain consistent:

• Connector Type: Receptacle configuration
• Position Count: 50 positions
• Row Configuration: 2 rows
• Mounting Orientation: Through hole, right-angle mounting
• Termination Method: Solder termination
• Connector Style: Outer shroud contacts
• Contact Finish: Gold plating
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute part 1734037-5 (TE Connectivity AMP Connectors) meets all these critical parameters. This part is classified as active product status with current manufacturing support, making it suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The PHEC50R-R110LF is obsolete and no longer in active production. The substitute part 1734037-5 maintains functional equivalence across all critical electrical and mechanical parameters while offering the advantage of active product status with ongoing manufacturer support.

The 1734037-5 provides additional compliance benefits through ROHS3 certification and REACH compliance documentation, which may be required for new designs or systems subject to environmental regulations. Both parts share identical connector architecture, position count, mounting configuration, and termination method, ensuring direct functional replacement capability.

Frequently Asked Questions (FAQ)

Q: Can the 1734037-5 directly replace the PHEC50R-R110LF in existing applications?

A: Yes. Both connectors share identical specifications for connector type, position count, row configuration, mounting orientation, termination method, and contact finish. The 1734037-5 is functionally equivalent and suitable for direct replacement.

Q: What is the significance of the "Board to Board" designation on the 1734037-5?

A: The 1734037-5 is specified as a board-to-board connector type with board lock features. This designation indicates the connector's intended application context but does not affect its electrical or mechanical compatibility with the PHEC50R-R110LF for solder termination applications.

Q: Are there compliance differences between these two parts?

A: The 1734037-5 includes documented ROHS3 compliance and REACH unaffected status. The PHEC50R-R110LF compliance information is not specified in available documentation. For applications requiring environmental compliance certification, the 1734037-5 provides documented compliance status.

Q: What is the packaging difference?

A: The PHEC50R-R110LF packaging is not specified. The 1734037-5 is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are the contact finish specifications identical?

A: Both parts feature gold contact finish. The PHEC50R-R110LF specifies 3.94µin (0.10µm) thickness, while the 1734037-5 specifies flash gold plating. Both meet gold plating requirements for D-Sub connector applications.
