• Number of rows (2)
• Pitch spacing (0.118" / 3.00mm)
• Row spacing (0.118" / 3.00mm)
• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Insulation height (0.290" / 7.37mm)

Electrical Compatibility Parameters:

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

Functional Parameters:

• Termination method (Solder)
• Fastening type (Locking Ramp)
• Features (Board Lock)
• Style (Board to Cable/Wire)

The substitute part 5-794626-0 maintains full equivalence across all mechanical and electrical parameters. Differences in contact finish specifications and product status do not affect functional interchangeability in board-level applications.

Parameter Comparison

Engineering Selection Recommendations

The 5-794626-0 serves as the direct active equivalent for the obsolete 5-794621-0. Both components are manufactured by TE Connectivity within the Micro MATE-N-LOK series and maintain identical mechanical and electrical specifications across all critical parameters.

Product Status Consideration: The 5-794621-0 is classified as obsolete, while the 5-794626-0 maintains active product status. For new designs and ongoing production requirements, the 5-794626-0 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Status: Both parts satisfy RoHS compliance requirements. The 5-794626-0 carries ROHS3 certification, representing the current regulatory standard. The 5-794621-0 carries RoHS Compliant status. Both components maintain UL94 V-0 material flammability ratings and operate across the identical temperature range of -40°C to 105°C at 250V.

Contact Finish Specification: The primary technical difference between these parts is the mating contact finish. The 5-794621-0 features tin plating (100.0µin / 2.54µm), while the 5-794626-0 features gold plating (30.0µin / 0.76µm) on mating contacts. Gold plating provides enhanced corrosion resistance and contact reliability in applications subject to environmental exposure or extended storage periods. Both finishes are suitable for general-purpose board-to-cable/wire interconnection applications.

Moisture Sensitivity: The 5-794621-0 carries MSL 1 (Unlimited), while the 5-794626-0 carries MSL 2 (1 Year). This difference reflects standard industry practice for active components and does not impact functional performance in typical manufacturing and field deployment environments.

Frequently Asked Questions (FAQ)

Q: Can the 5-794626-0 directly replace the 5-794621-0 in existing designs?

A: Yes. The 5-794626-0 maintains full mechanical and electrical equivalence with the 5-794621-0 across all critical parameters including connector series, position count, pitch spacing, mounting configuration, operating temperature range, and voltage rating.
