Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle with outer shroud contacts
• Position Count: 40 positions
• Contact Pitch: 0.050" (1.27mm)
• Row Configuration: 2 rows
• Mounting Orientation: Through hole, right angle
• Contact Material and Finish: Gold plating at 11.8µin (0.30µm) thickness
• Mechanical Features: Board lock functionality
• Height Above Board: 0.335" (8.50mm)
• Series Classification: Free Height (FH)

The substitute part 5176379-1 maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional compatibility with applications designed for the 176379-1.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5176379-1

The 5176379-1 is the direct functional equivalent of the 176379-1 across all electrical and mechanical parameters. Selection of the 5176379-1 is supported by the following factors:

• Product Status: The 5176379-1 maintains active product status, ensuring continued availability and manufacturing support.
• Compliance: The 5176379-1 is RoHS Compliant, meeting current regulatory requirements for new designs and applications subject to RoHS directives.
• Electrical Equivalence: All contact specifications, pitch, position count, and finish thickness are identical.
• Mechanical Compatibility: Mounting type, orientation, height above board, and board lock features are identical, ensuring direct PCB compatibility.
• Series Continuity: Both parts operate within the Free Height (FH) series classification.

The 176379-1, classified as obsolete, should be replaced with the 5176379-1 in new designs and where component refresh is required. Existing assemblies using the 176379-1 may continue operation; however, long-term supply continuity is supported through the 5176379-1.

Frequently Asked Questions (FAQ)

Q: Can the 5176379-1 be used as a direct replacement for the 176379-1 in existing assemblies?

A: Yes. The 5176379-1 is electrically and mechanically equivalent to the 176379-1. All contact specifications, pitch, position count, mounting type, and board-level dimensions are identical. Direct substitution is supported without design modification.

Q: What is the primary difference between the 176379-1 and 5176379-1?

A: The 176379-1 is obsolete and RoHS non-compliant. The 5176379-1 is an active product with RoHS Compliance. All functional and electrical parameters remain identical.

Q: Are there packaging differences between these parts?

A: The 176379-1 packaging is not specified in the available data. The 5176379-1 is supplied in Bulk packaging. Confirm packaging requirements with your procurement or supply chain team.

Q: Does the RoHS Compliance status of the 5176379-1 affect compatibility with the 176379-1?

A: No. RoHS Compliance is a material composition and manufacturing process specification. It does not alter electrical performance, contact characteristics, or mechanical fit. The 5176379-1 is fully compatible with applications designed for the 176379-1.

Q: What is the contact finish thickness specification?

A: Both the 176379-1 and 5176379-1 feature gold contact finish at 11.8µin (0.30µm) thickness, ensuring consistent electrical performance and corrosion resistance.

Q: Are these connectors suitable for high-reliability applications?

A: Both parts feature gold-plated contacts, board lock functionality, and MSL 1 (Unlimited) moisture sensitivity rating. Suitability for specific high-reliability applications depends on application-specific requirements beyond the scope of this equivalency reference.

Q: What is the pitch specification, and why is it important?

A: The pitch is 0.050" (1.27mm), representing the center-to-center distance between adjacent contact positions. This specification is critical for PCB layout compatibility and mating connector selection. Both parts maintain identical pitch specifications.
