Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-794626-0 serves as the direct active equivalent to the obsolete 5-794624-0. Both connectors maintain identical electrical and mechanical specifications within the Micro MATE-N-LOK series, ensuring functional interchangeability in board-to-cable/wire applications.

Product Status Consideration: The 5-794626-0 is classified as Active, providing assured long-term availability and supply chain continuity compared to the Obsolete status of the 5-794624-0. This transition is critical for new designs and ongoing production requirements.

Compliance Status: Both parts maintain UL94 V-0 flammability ratings and are RoHS compliant. The 5-794626-0 carries ROHS3 compliance, representing the current regulatory standard. Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Contact Finish Specification: The primary technical distinction is the mating contact finish. The 5-794624-0 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 demanding environmental conditions. Post contact finish remains tin for both variants.

Moisture Sensitivity: The 5-794624-0 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 compatibility.

Packaging and Inventory: The 5-794626-0 is available in Cut Tape (CT) packaging with 2028 pieces in stock, compared to 1125 pieces of the 5-794624-0. The active status and higher inventory level of the 5-794626-0 support immediate procurement for production applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-794626-0 directly replace the 5-794624-0 in existing designs?

A: Yes. Both connectors maintain identical electrical and mechanical specifications including connector type, contact configuration, pitch, mounting orientation, shrouding, and operating parameters. The 5-794626-0 is the active equivalent designed for direct substitution.

Q: What is the significance of the different contact finishes between these parts?

A: The 5-794624-0 uses tin plating on mating contacts, while the 5-794626-0 uses gold plating. Gold plating provides superior corrosion resistance and contact reliability, particularly in high-humidity or corrosive environments. Both finishes are suitable for general-purpose applications at the specified voltage and temperature ratings.

Q: Are there any compatibility issues with existing mating connectors?

A: No. Both the 5-794624-0 and 5-794626-0 are members of the Micro MATE-N-LOK series with identical pitch (0.118" / 3.00mm), row spacing, shrouding configuration, and contact geometry. They mate with the same receptacle connectors.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: The 5-794624-0 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 5-794626-0 carries MSL 2 (1 Year), requiring storage in controlled humidity conditions for one year from the date of manufacture. This difference reflects standard industry practice for active components and does not affect functional performance or compatibility.

Q: Why is the 5-794624-0 classified as Obsolete?

A: The Obsolete status indicates that the 5-794624-0 is no longer in active production. The 5-794626-0 represents the current active equivalent within the Micro MATE-N-LOK series, ensuring continued availability and supply chain support for new and ongoing applications.

Q: What packaging options are available for the substitute part?

A: The 5-794626-0 is supplied in Cut Tape (CT) packaging, which is standard for surface mount components. This packaging format is compatible with automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. The 5-794624-0 is RoHS Compliant, and the 5-794626-0 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions. ROHS3 represents the current regulatory standard.
