Key Parameters

Substitute Part Grouping Explanation

The 71600-050LF qualifies as a direct substitute for the 66432-150LF based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Both are 50-position rectangular receptacle connectors with female socket contacts
• Electrical Interface: Identical pitch (0.100" / 2.54mm), row configuration (2 rows), and row spacing (0.100" / 2.54mm)
• Termination Method: Both utilize IDC (Insulation Displacement Contact) termination for ribbon cable
• Wire Compatibility: Both accept 28-30 AWG ribbon cable
• Contact Finish Specification: Both feature gold contact finish at 30.0µin (0.76µm) thickness
• Mechanical Features: Both include feed through, polarizing key, and strain relief
• Environmental Rating: Both have MSL 1 (Unlimited) moisture sensitivity level

The primary distinction is product status: the 66432-150LF is obsolete while the 71600-050LF is active, making the latter the recommended procurement choice for new designs and ongoing support.

Frequently Asked Questions (FAQ)

Q: Can the 71600-050LF directly replace the 66432-150LF in existing assemblies?

A: Yes. Both connectors share identical electrical and mechanical specifications: 50-position configuration, 0.100" pitch, 2-row layout, IDC termination, 28-30 AWG wire compatibility, and gold contact finish at 30.0µin thickness. Physical and functional compatibility is confirmed.

Q: What is the primary reason for substitution?

A: The 66432-150LF is obsolete. The 71600-050LF is the active equivalent from the same manufacturer and series, ensuring ongoing availability and manufacturer support.

Q: Are there packaging differences between these parts?

A: The 66432-150LF packaging is not specified in the technical data. The 71600-050LF is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both connectors meet current regulatory standards?

A: The 71600-050LF is certified RoHS Compliant and REACH Unaffected. The 66432-150LF regulatory status is not specified. For new designs and compliance-critical applications, the 71600-050LF is the appropriate choice.

Q: Are the contact finish specifications identical?

A: Both connectors feature gold contact finish at 30.0µin (0.76µm) thickness. The 66432-150LF specifies "Gold or Gold, GXT™" while the 71600-050LF specifies "Gold." This difference does not affect electrical or mechanical compatibility.

Q: What is the MSL rating for both connectors?

A: Both the 66432-150LF and 71600-050LF have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
