Key Parameters

Substitute Part Grouping Explanation

Substitution of the 794679-4 connector is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Number of rows (2)
• Pitch - mating (0.118" / 3.00mm)
• Row spacing - mating (0.118" / 3.00mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Insulation height (0.290" / 7.37mm)
• Contact shape (Square)

Electrical Compatibility Parameters:

• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)
• Contact material (Brass)
• Contact finish - mating (Gold)
• Insulation material (Polyamide / Nylon)

Termination Parameters:

• Termination method (Solder)
• Fastening type (Locking Ramp)

The substitute part 3-794679-4 maintains full equivalence across all mechanical and electrical parameters. The primary distinction is product status (Active vs. Obsolete) and regulatory compliance (RoHS3 Compliant vs. RoHS non-compliant), with a secondary difference in post contact finish material composition.

Parameter Comparison

Engineering Selection Recommendations

The 3-794679-4 connector serves as the direct active equivalent to the obsolete 794679-4 part number. Both connectors maintain identical mechanical and electrical specifications across all critical parameters including pitch, position count, mounting configuration, and operating characteristics.

The primary distinction between these parts is regulatory status. The 794679-4 is classified as obsolete and RoHS non-compliant, while the 3-794679-4 is an active product with RoHS3 compliance certification. For new designs and ongoing production applications, the 3-794679-4 is the appropriate selection to ensure component availability and regulatory alignment.

A secondary difference exists in the post contact finish material: the 794679-4 uses Tin-Lead plating while the 3-794679-4 uses Tin plating. Both finishes maintain the specified contact finish thickness of 100.0µin (2.54µm) and are compatible with solder termination processes. The Tin finish in the substitute part aligns with contemporary lead-free manufacturing standards.

Both connectors are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 3-794679-4 be used as a direct replacement for the 794679-4 in existing designs?

A: Yes. The 3-794679-4 maintains full mechanical and electrical equivalence to the 794679-4 across all critical parameters including connector type, position count, pitch spacing, mounting configuration, voltage rating, and operating temperature range. The parts are functionally interchangeable.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 794679-4 is RoHS non-compliant, while the 3-794679-4 is RoHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 3-794679-4 is the required selection. The 794679-4 may only be used in applications where RoHS exemptions apply.

Q: How does the contact finish difference affect connector performance?

A: The 794679-4 uses Tin-Lead post finish while the 3-794679-4 uses Tin post finish. Both maintain identical contact finish thickness (100.0µin / 2.54µm) and are compatible with solder termination. The Tin finish in the substitute part reflects current manufacturing standards and lead-free compliance.

Q: Are there packaging differences between these parts?

A: The 794679-4 packaging specification is not provided in the available data. The 3-794679-4 is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the inventory status of these parts?

A: The 794679-4 (obsolete) has 1109 pieces in stock. The 3-794679-4 (active) has 5914 pieces in stock, providing greater availability for ongoing production requirements.

Q: Do these connectors require special moisture handling during storage?

A: No. Both connectors are classified as Moisture Sensitivity Level 1 (Unlimited), indicating unlimited shelf life without special moisture control measures.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 794679-4 and 3-794679-4 operate across the identical temperature range of -40°C to 105°C.
