Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-794636-0 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (20)
• Number of rows (2)
• Pitch spacing (0.118" / 3.00mm)
• Row spacing (0.118" / 3.00mm)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)

Electrical Compatibility:

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

Functional Compatibility:

• Termination method (Solder)
• Series designation (Micro MATE-N-LOK)
• Style (Board to Cable/Wire)

The substitute part 5-794636-0 maintains full equivalence across all mechanical, electrical, and functional parameters. The primary differences are packaging format and product status, with the substitute offering active product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 5-794636-0 serves as a direct functional equivalent to the obsolete 2-794636-0 for all mechanical and electrical applications. Both parts maintain identical specifications across connector geometry, pitch spacing, contact configuration, voltage rating, and operating temperature range.

Product Status Consideration: The 2-794636-0 carries obsolete status, indicating discontinued manufacturing and limited availability. The 5-794636-0 maintains active product status with higher inventory availability (1601 units versus 960 units), ensuring supply chain continuity for new designs and ongoing production requirements.

Compliance Consideration: The 5-794636-0 is RoHS Compliant, whereas the 2-794636-0 carries "Not applicable" RoHS status. This distinction reflects the contact finish composition: the substitute uses pure Tin finish, while the main part uses Tin-Lead finish. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and electrical performance characteristics.

Packaging Consideration: The 5-794636-0 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. The main part packaging format is not specified in available documentation.

For new designs, production continuity, and regulatory compliance requirements, the 5-794636-0 is the appropriate selection. For legacy system maintenance where Tin-Lead contact finish is specifically required, the 2-794636-0 remains available in limited quantities.

Frequently Asked Questions (FAQ)

Q: Can the 5-794636-0 be used as a direct replacement for the 2-794636-0 in existing designs?

A: Yes. The 5-794636-0 maintains full mechanical and electrical equivalence across all critical parameters: 20-position, 2-row configuration; 3.00mm pitch spacing; surface mount termination; 250V voltage rating; and -40°C to 105°C operating temperature range. The parts are functionally interchangeable at the circuit board level.

Q: What is the difference between the Tin-Lead finish on the 2-794636-0 and the Tin finish on the 5-794636-0?

A: The contact finish composition differs due to RoHS compliance requirements. The 2-794636-0 uses Tin-Lead (Pb-containing) finish, while the 5-794636-0 uses pure Tin finish. Both maintain identical finish thickness (100.0µin / 2.54µm). The Tin finish on the 5-794636-0 provides equivalent electrical conductivity and contact reliability for the specified voltage and current applications.

Q: Why is the 2-794636-0 marked as obsolete?

A: Obsolete status indicates the part has been discontinued by the manufacturer. The 5-794636-0 represents the active production equivalent, incorporating modern RoHS-compliant materials while maintaining full functional compatibility.

Q: What packaging format should I specify for high-volume assembly?

A: The 5-794636-0 is supplied in Tape & Reel (TR) format, which is the standard packaging for automated surface mount assembly operations. This format provides component feeding compatibility with standard pick-and-place equipment.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C to 105°C) and maintain the same 250V voltage rating. Current rating varies by wire gauge for both parts. Electrical performance is equivalent.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both the 2-794636-0 and 5-794636-0 carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage or handling.

Q: Can I mix 2-794636-0 and 5-794636-0 parts in the same production batch?

A: Yes. Both parts are mechanically and electrically equivalent and can be used interchangeably in the same assembly. However, for traceability and compliance documentation, it is recommended to maintain consistent part number usage within a single production lot.
