Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-794679-2 is the direct equivalent for the obsolete 794679-2. Selection of the substitute is based on the following engineering criteria:

Product Status: The original 794679-2 is classified as Obsolete. The substitute 3-794679-2 is Active, ensuring ongoing availability and manufacturing support.

Regulatory Compliance: The substitute part 3-794679-2 is ROHS3 Compliant, meeting current environmental and regulatory requirements. The original part status is Not applicable.

Functional Equivalence: All critical electrical and mechanical parameters are identical between the main part and substitute, including connector type, contact configuration, mounting specifications, operating temperature range, voltage rating, and material flammability rating.

Contact Finish Difference: The substitute part features Tin contact finish on the post, compared to Tin-Lead on the original part. This change reflects current manufacturing standards and regulatory compliance with lead-free requirements. The mating contact finish remains Gold on both parts.

Packaging: The substitute is supplied in Tray packaging, which is standard for active production parts.

For applications currently using 794679-2, direct substitution with 3-794679-2 is appropriate without design modification.

Frequently Asked Questions (FAQ)

Q: Can 3-794679-2 be used as a direct replacement for 794679-2?

A: Yes. The 3-794679-2 is a direct functional equivalent. All critical electrical and mechanical parameters are identical, including connector type, position count, row spacing, mounting configuration, operating temperature range, and voltage rating. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the contact finishes on the two parts?

A: The original 794679-2 uses Tin-Lead contact finish on the post, while the substitute 3-794679-2 uses Tin. Both parts maintain Gold contact finish on the mating surface. The change to Tin reflects current manufacturing standards and compliance with lead-free requirements. This difference does not affect electrical or mechanical compatibility.

Q: Why is the original 794679-2 listed as Obsolete?

A: The 794679-2 is no longer in active production. The 3-794679-2 is the current active equivalent that replaces it in the product line.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 3-794679-2 is ROHS3 Compliant. The original 794679-2 has RoHS Status listed as Not applicable.

Q: Are there packaging differences between the two parts?

A: Yes. The original 794679-2 packaging is not specified in the available data. The substitute 3-794679-2 is supplied in Tray packaging, which is standard for active production parts.

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

A: Micro MATE-N-LOK is the connector series designation for both the original and substitute parts. This series designation indicates the connector family, form factor, and mating interface specifications.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts share identical mechanical specifications including insulation height of 0.290" (7.37mm), row spacing of 0.118" (3.00mm), contact shape (Square), shrouding configuration (Shrouded - 4 Wall), and mounting type (Through Hole, Right Angle).

Q: What is the operating temperature range for these connectors?

A: Both the original 794679-2 and substitute 3-794679-2 operate across the temperature range of -40°C to 105°C.

Q: What voltage rating applies to these connectors?

A: Both parts are rated for 250V operation.

Q: Is the Board Lock feature present on both parts?

A: Yes. Both the original 794679-2 and substitute 3-794679-2 include the Board Lock feature.
