Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for direct substitution of the 794679-6 are:

Critical Matching Parameters:

• Connector series: Micro MATE-N-LOK
• Number of positions and rows: 6 positions, 2 rows
• Pitch configuration: 0.118" (3.00mm) mating pitch and row spacing
• Connector type and contact type: Header with male pins
• Mounting configuration: Through hole, right angle
• Termination method: Solder
• Shrouding design: Shrouded - 4 wall
• Fastening mechanism: Locking ramp
• Electrical ratings: 250V voltage rating
• Temperature range: -40°C ~ 105°C
• Contact materials and finishes: Brass with gold mating finish
• Insulation specifications: Polyamide (PA), Nylon with UL94 V-0 rating

The substitute part 3-794679-6 maintains all critical electrical and mechanical parameters identical to the main part. The primary distinction is product status (active versus obsolete) and packaging format (tray versus unspecified), along with minor contact finish post material variation (tin versus tin-lead) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The part 3-794679-6 is the direct active equivalent to the obsolete 794679-6. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 794679-6 carries obsolete status, while 3-794679-6 is active. For new designs and ongoing production support, the active part number ensures continued availability and manufacturer support.

Compliance and Certification: The substitute part 3-794679-6 carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for modern applications. The main part lists RoHS status as not applicable and REACH status as vendor undefined, indicating legacy compliance documentation.

Electrical and Mechanical Equivalence: All critical connector specifications remain identical between the two parts, including pitch, position count, voltage rating, temperature range, and mechanical mounting configuration. The connector maintains full compatibility with existing mating components and PCB layouts.

Contact Finish Post Material: The substitute part specifies tin post finish compared to tin-lead in the main part. Both finishes are compatible with standard solder assembly processes and provide equivalent electrical performance for general-purpose applications.

Packaging: The substitute part is supplied in tray packaging, which is standard for production environments and provides improved handling and inventory management compared to unspecified packaging of the main part.

For new designs, production continuity, and regulatory compliance, 3-794679-6 is the recommended selection. For legacy system repairs requiring exact original specifications, the main part 794679-6 may be sourced from existing inventory if available.

Frequently Asked Questions (FAQ)

Q: Can 3-794679-6 be used as a direct replacement for 794679-6 in existing designs?

A: Yes. The parts are electrically and mechanically equivalent across all critical parameters including pitch, position count, voltage rating, temperature range, and mounting configuration. The connector maintains full compatibility with existing mating components and PCB layouts.

Q: What is the difference between the tin-lead post finish on 794679-6 and the tin post finish on 3-794679-6?

A: Both finishes are compatible with standard solder assembly processes. Tin post finish on 3-794679-6 represents modern manufacturing practice and provides equivalent electrical performance for general-purpose applications. The difference does not affect connector functionality or reliability.

Q: Why is 794679-6 listed as obsolete?

A: Product obsolescence indicates the part is no longer in active production. The active equivalent 3-794679-6 provides continued access to the same connector specifications with current manufacturer support and compliance certifications.

Q: Does 3-794679-6 have better compliance certifications than 794679-6?

A: Yes. The substitute part 3-794679-6 carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment. The main part lists RoHS status as not applicable and REACH status as vendor undefined, indicating legacy compliance documentation.

Q: Are there any packaging differences between these parts?

A: The main part 794679-6 has unspecified packaging, while 3-794679-6 is supplied in tray packaging. Tray packaging is standard for production environments and provides improved handling and inventory management.

Q: What is the Micro MATE-N-LOK series?

A: Micro MATE-N-LOK is the connector series designation for both parts. This series defines the connector family, mating interface, and mechanical specifications. Both 794679-6 and 3-794679-6 belong to this series and are fully compatible.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for operating temperatures from -40°C to 105°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the voltage rating for these connectors?

A: Both 794679-6 and 3-794679-6 are rated for 250V operation. This rating applies to the connector itself; actual circuit voltage must be verified against system requirements.

Q: Are these connectors suitable for general-purpose applications?

A: Yes. Both parts are designated for general-purpose applications. The 6-position, 3.00mm pitch configuration with board lock feature and locking ramp fastening provides reliable performance across standard industrial and commercial applications.
