Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 794619-4 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Number of positions (4)
• Number of rows (2)
• Pitch spacing (0.118" / 3.00mm)
• Row spacing (0.118" / 3.00mm)
• Mounting configuration (Through Hole, Right Angle)
• Contact type (Male Pin)
• Shrouding style (Shrouded - 4 Wall)

Electrical Compatibility:

• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)
• Material flammability rating (UL94 V-0)

Functional Equivalence:

• Series designation (Micro MATE-N-LOK)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide/Nylon)
• Contact material (Brass)

The substitute part 3-794619-4 maintains identical specifications across all critical parameters while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-794619-4 is the direct functional equivalent of the obsolete 794619-4. Both parts share identical electrical and mechanical specifications, including connector type, position count, pitch spacing, mounting configuration, voltage rating, and operating temperature range.

The primary distinction between the two parts is product status and regulatory compliance. The main part 794619-4 is classified as obsolete and carries RoHS non-compliant status. The substitute part 3-794619-4 is active and RoHS compliant, providing improved regulatory alignment for new designs and ongoing production requirements.

The contact finish on the post differs between the two parts: the main part uses Tin-Lead while the substitute uses Tin. Both finishes maintain the same thickness specification of 100.0µin (2.54µm) and are compatible with solder termination processes. This difference reflects the RoHS compliance transition in the product line.

The substitute part is supplied in Tray packaging, whereas the main part packaging is not specified. This packaging difference does not affect electrical or mechanical compatibility.

For applications requiring active product status, regulatory compliance, and long-term component availability, the 3-794619-4 is the appropriate selection. The parts are mechanically and electrically interchangeable within the Micro MATE-N-LOK series.

Frequently Asked Questions (FAQ)

Q: Are the 794619-4 and 3-794619-4 mechanically interchangeable?

A: Yes. Both parts feature identical mounting type (Through Hole, Right Angle), position count (4), row configuration (2 rows), and pitch spacing (0.118" / 3.00mm). They are mechanically interchangeable in board-level applications.

Q: What is the difference in contact finish between these parts?

A: The main part 794619-4 uses Tin-Lead finish on the post, while the substitute 3-794619-4 uses Tin finish. Both maintain the same thickness specification of 100.0µin (2.54µm). The Tin finish on the substitute reflects RoHS compliance requirements. Both finishes are compatible with standard solder termination processes.

Q: Why is the main part 794619-4 listed as obsolete?

A: The 794619-4 is obsolete and has been superseded by the active equivalent 3-794619-4. The substitute part offers improved regulatory compliance (RoHS compliant) and maintains full electrical and mechanical compatibility.

Q: Does the packaging difference affect component selection?

A: No. The packaging difference (Tray for the substitute versus unspecified for the main part) does not affect electrical or mechanical compatibility. Packaging selection is determined by procurement and inventory management requirements rather than functional performance.

Q: Are both parts rated for the same voltage and temperature range?

A: Yes. Both parts are rated for 250V voltage and operate across the identical temperature range of -40°C to 105°C. They share the same UL94 V-0 flammability rating and are suitable for identical applications.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. No special storage or handling precautions are necessary.

Q: Can the 3-794619-4 be used as a direct replacement in existing designs using 794619-4?

A: Yes. The 3-794619-4 is a direct functional equivalent with identical mechanical and electrical specifications. It can be used as a replacement in existing designs without modification to PCB layouts, mating connectors, or wire gauge specifications.
