Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 794678-6 is based on strict electrical and mechanical parameter matching within the Micro MATE-N-LOK series. The substitute part must maintain identical specifications across the following critical parameters:

• Connector Configuration: 6-position, 2-row header with 0.118" (3.00mm) pitch and row spacing
• Mounting Orientation: Through-hole, right-angle mounting
• Contact System: Male pin contacts with gold-plated mating surfaces
• Electrical Ratings: 250V voltage rating and temperature range of -40°C to 105°C
• Mechanical Features: Shrouded 4-wall design with board lock fastening and locking ramp
• Termination Method: Solder termination with tin or tin-lead post finish
• Material Compliance: UL94 V-0 flammability rating and polyamide/nylon insulation

The substitute part 3-794678-6 satisfies all these parameters while offering the advantage of active product status and improved RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-794678-6 is the direct equivalent for the obsolete 794678-6. Selection of the substitute is based on the following engineering criteria:

Product Status: The main part 794678-6 carries obsolete status, which restricts long-term availability and support. The substitute 3-794678-6 maintains active product status, ensuring continued manufacturing support and supply chain reliability.

Regulatory Compliance: The substitute 3-794678-6 is ROHS3 compliant, whereas the main part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in most markets.

Electrical and Mechanical Compatibility: All critical electrical parameters (voltage rating, operating temperature range, contact materials, and finishes) are identical between the main part and substitute. The mechanical configuration, including pitch spacing, mounting orientation, shrouding design, and fastening mechanism, is fully preserved.

Contact Finish Consideration: The substitute features tin post finish compared to the main part's tin-lead finish. Both finishes are compatible with solder termination processes and maintain equivalent electrical performance within the specified operating parameters.

Packaging: The substitute is supplied in tray packaging, which is standard for production environments and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can 3-794678-6 be used as a direct replacement for 794678-6 in existing designs?

A: Yes. The 3-794678-6 is a direct functional equivalent with identical electrical and mechanical specifications. All mating dimensions, contact configurations, and electrical ratings are preserved. The connector will interface with existing mating components without modification.

Q: What is the difference between the tin-lead post finish on 794678-6 and the tin post finish on 3-794678-6?

A: Both finishes are suitable for solder termination and provide equivalent electrical performance. Tin post finish on the substitute eliminates lead content, aligning with RoHS3 compliance requirements. The change does not affect solderability or contact reliability within the specified operating temperature range.

Q: Why is the substitute part marked as active while the main part is obsolete?

A: The main part 794678-6 has been discontinued by the manufacturer. The substitute 3-794678-6 represents the current production equivalent within the Micro MATE-N-LOK series, ensuring ongoing availability and manufacturing support.

Q: Does the tray packaging of 3-794678-6 affect its compatibility with 794678-6?

A: No. Packaging format does not affect connector functionality or compatibility. Tray packaging is a standard distribution method for production quantities and does not alter electrical or mechanical performance.

Q: Are there any temperature or voltage derating considerations when substituting 3-794678-6 for 794678-6?

A: No. Both parts maintain identical voltage rating (250V) and operating temperature range (-40°C to 105°C). No derating or operational adjustments are required.

Q: Is the RoHS3 compliance of 3-794678-6 a requirement for substitution?

A: RoHS3 compliance of the substitute is an advantage for regulatory alignment and future-proofing. If your application or market requires RoHS compliance, the substitute 3-794678-6 satisfies this requirement, whereas the main part does not.

Q: Can both parts be used interchangeably in the same assembly?

A: Yes. The parts are mechanically and electrically interchangeable. Both feature identical mating dimensions, contact configurations, and electrical specifications. They can be used interchangeably without design modification or performance impact.
