Key Parameters

Substitute Part Grouping Explanation

The 71600-014LF qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Position Count: Both are 14-position receptacle connectors
• Pitch & Row Configuration: Identical 0.100" (2.54mm) pitch with 2-row layout and 0.100" row spacing
• Cable Termination Method: Both use IDC termination for ribbon cable
• Wire Gauge Compatibility: Both support 28-30 AWG wire gauge
• Contact Configuration: Both feature female socket contacts with gold finish (30.0µin thickness)
• Mechanical Features: Both include feed through, polarizing key, and strain relief
• Series Compatibility: Both belong to the Quickie™ series

The primary distinction is product status: 66432-114LF is obsolete, while 71600-014LF is active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

The 71600-014LF is the direct active equivalent for the obsolete 66432-114LF. Both connectors share identical electrical and mechanical specifications within the Quickie™ series, ensuring functional compatibility in applications requiring 14-position IDC ribbon cable receptacles with 28-30 AWG wire termination.

The 71600-014LF offers the advantage of active product status with current manufacturing support and RoHS compliance certification, making it suitable for new designs and ongoing production requirements. The connector maintains the same contact finish thickness and gold plating specification, preserving signal integrity and reliability characteristics of the original design.

Frequently Asked Questions (FAQ)

Q: Can 71600-014LF directly replace 66432-114LF in existing assemblies?

A: Yes. Both connectors are mechanically and electrically identical in all critical parameters: 14-position configuration, 0.100" pitch, 2-row layout, IDC termination, and 28-30 AWG wire gauge compatibility. The polarizing key and strain relief features are present on both parts.

Q: What is the difference between the contact finishes?

A: The 66432-114LF specifies gold or gold GXT™ finish, while the 71600-014LF specifies gold finish. Both maintain 30.0µin (0.76µm) contact finish thickness, meeting the same electrical performance requirements.

Q: Why is 66432-114LF marked obsolete?

A: Product obsolescence indicates the part is no longer in active production. The 71600-014LF serves as the current production equivalent within the same Quickie™ series.

Q: Are there packaging differences between these parts?

A: The 71600-014LF is supplied in tube packaging. Packaging format does not affect connector functionality or compatibility.

Q: Does 71600-014LF meet current compliance standards?

A: Yes. The 71600-014LF is RoHS compliant and REACH affected, meeting current regulatory requirements for electronic components.
