Engineering Selection Recommendations

TE Connectivity 5-794677-0 (Direct Equivalent)

The 5-794677-0 is the primary substitute for the obsolete 2-794677-0. Both parts share identical mechanical and electrical specifications within the Micro MATE-N-LOK series. The 5-794677-0 is currently in active production status with higher inventory availability (1427 pieces). The primary difference is the contact finish specification: the 5-794677-0 uses Tin plating instead of Tin-Lead, and it carries ROHS3 compliance certification. This part is suitable for direct replacement in new designs and legacy system updates where RoHS compliance is required or preferred.

Molex 0430452000 (Cross-Manufacturer Substitute)

The 0430452000 provides functional equivalence as a cross-manufacturer alternative from the Molex Micro-Fit 3.0 series. This part meets all mandatory mechanical and electrical parameters. Advantages include higher voltage rating (600V versus 250V), specified current rating (8A), and active production status with substantial inventory (6384 pieces). The insulation material differs (Liquid Crystal Polymer with glass fill versus Polyamide/Nylon), offering enhanced thermal and mechanical properties. Both parts carry ROHS3 compliance and UL94 V-0 flammability ratings. Selection of this part is appropriate when higher electrical performance margins or enhanced material properties are beneficial to the application.

Compliance Considerations

The original 2-794677-0 is RoHS non-compliant. Both substitute parts (5-794677-0 and 0430452000) are ROHS3 compliant, meeting current regulatory requirements for electronic component procurement in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the 5-794677-0 be used as a direct replacement for the 2-794677-0?

A: Yes. The 5-794677-0 is a direct equivalent within the TE Connectivity Micro MATE-N-LOK series. Both parts share identical pitch (3.00mm), position count (20), row configuration (2 rows), mounting style (through-hole right-angle), and operating temperature range (-40°C to 105°C). The primary difference is the contact finish specification (Tin versus Tin-Lead) and RoHS compliance status. The 5-794677-0 is suitable for direct PCB layout and mating interface replacement.

Q: What are the key differences between the TE Connectivity 5-794677-0 and the Molex 0430452000?

A: Both parts meet the mandatory mechanical and electrical parameters for substitution. Key differences include: (1) Manufacturer series—TE Connectivity Micro MATE-N-LOK versus Molex Micro-Fit 3.0; (2) Voltage rating—250V versus 600V; (3) Current rating—varies by wire gauge versus 8A specified; (4) Insulation material—Polyamide/Nylon versus Liquid Crystal Polymer with glass fill; (5) Contact material—Brass versus Brass Alloy. The Molex part offers higher electrical performance margins and enhanced material properties.

Q: Are the mating interfaces compatible between these three parts?

A: The 2-794677-0 and 5-794677-0 share identical mating interfaces within the Micro MATE-N-LOK series. The Molex 0430452000 operates within the Micro-Fit 3.0 series and has a different mating interface. Existing cable assemblies or mating connectors designed for the 2-794677-0 or 5-794677-0 will not mate with the 0430452000 without corresponding mating connector substitution.

Q: What is the packaging difference between these parts?

A: The 2-794677-0 packaging specification is not provided. The 5-794677-0 and 0430452000 are both supplied in Tray packaging. Confirm packaging requirements with procurement specifications before finalizing part selection.

Q: Are there RoHS compliance implications for using these substitutes?

A: The original 2-794677-0 is RoHS non-compliant. Both substitute parts (5-794677-0 and 0430452000) are ROHS3 compliant. If the application or market requires RoHS compliance, either substitute part satisfies this requirement. If legacy non-compliant specifications are mandated, neither substitute is appropriate.

Q: What is the inventory status for each part?

A: The 2-794677-0 (obsolete) has 777 pieces in stock. The 5-794677-0 (active) has 1427 pieces available. The 0430452000 (active) has 6384 pieces available. For long-term procurement planning, the active-status parts provide greater supply security.

Q: Can the Molex 0430452000 be used in applications requiring the 250V rating of the original part?

A: Yes. The 0430452000 has a 600V voltage rating, which exceeds the 250V requirement of the 2-794677-0. Higher voltage ratings are acceptable for applications designed to the lower specification.
