Engineering Selection Recommendations

Primary Recommendation: 3-794627-2

The substitute part 3-794627-2 is the direct equivalent for the obsolete TE Connectivity 794627-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 794627-2 carries Obsolete status, indicating discontinued production and limited availability. The substitute 3-794627-2 maintains Active product status, ensuring ongoing supply chain availability and manufacturer support.

Compliance Certifications: The substitute part 3-794627-2 is ROHS3 Compliant, whereas the main part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in regulated markets and applications.

Functional Equivalence: All mechanical, electrical, and functional parameters remain identical between the main part and substitute. The connector maintains the same 2-position configuration, Surface Mount Right Angle mounting, Micro MATE-N-LOK series designation, and operating specifications.

Contact Finish Consideration: The substitute part features Tin contact finish on both mating and post surfaces, compared to Tin-Lead finish on the main part. Tin finish provides equivalent electrical performance and solder compatibility while supporting lead-free manufacturing processes.

Packaging Format: The substitute is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The main part is supplied in bulk packaging. Selection between packaging formats depends on production volume and assembly methodology.

Inventory Availability: The substitute part 3-794627-2 has 778 pieces in stock, providing immediate availability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can 3-794627-2 be used as a direct replacement for 794627-2 in existing designs?

A: Yes. The substitute part 3-794627-2 is mechanically and electrically equivalent to 794627-2. All critical parameters including position count, row spacing, mounting configuration, operating temperature range, and voltage rating are identical. The connector will mate with the same cable assemblies and perform identically in the application.

Q: What is the difference between the contact finishes (Tin-Lead vs. Tin)?

A: The main part 794627-2 uses Tin-Lead contact finish, while the substitute 3-794627-2 uses Tin finish. Both finishes provide equivalent electrical conductivity and solder wettability. Tin finish is compatible with lead-free solder processes and supports RoHS compliance requirements. The functional performance in the application is identical.

Q: Why is the main part 794627-2 listed as Obsolete?

A: Obsolete status indicates that TE Connectivity has discontinued production of this part number. The substitute part 3-794627-2 represents the active equivalent in the product line, ensuring continued availability and manufacturer support for new designs and production orders.

Q: Does the RoHS3 compliance of 3-794627-2 affect compatibility?

A: No. RoHS3 compliance of the substitute part indicates adherence to current regulatory standards for restricted substances. This compliance status does not affect electrical or mechanical compatibility. The substitute part is suitable for applications requiring RoHS-compliant components.

Q: What is the difference in packaging between 794627-2 and 3-794627-2?

A: The main part 794627-2 is supplied in bulk packaging, while the substitute 3-794627-2 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly processes. Selection depends on production volume and assembly equipment capabilities. Both packaging formats contain the same connector component.

Q: Are there any performance differences between the two parts?

A: No. Both parts operate identically across all electrical and mechanical parameters. Operating temperature range (-40°C ~ 105°C), voltage rating (250V), current rating (varies by wire gauge), and all physical dimensions are identical. The parts are functionally interchangeable.

Q: Can I mix 794627-2 and 3-794627-2 in the same production batch?

A: Yes. Both parts are mechanically and electrically equivalent and will perform identically in the application. However, for traceability and compliance documentation, it is recommended to maintain consistent part number usage within a single production lot when possible.

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

A: Both parts carry MSL 2 (1 Year) rating. This indicates the component can be stored in standard conditions for up to one year without requiring special moisture control measures. Standard handling and storage practices are appropriate for these connectors.
