Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-794629-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5-794629-2 qualifies as a direct equivalent based on the following criteria:

Critical Matching Parameters:

• Identical connector series (Micro MATE-N-LOK)
• Identical number of positions (22) and row configuration (2 rows)
• Identical pitch spacing (0.118" / 3.00mm) for both mating and row spacing
• Identical mounting type (Surface Mount, Right Angle)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Identical termination method (Solder) and fastening type (Locking Ramp)
• Identical voltage rating (250V) and operating temperature range (-40°C ~ 105°C)
• Identical contact material (Brass) and mating contact finish (Gold)
• Identical insulation material (Polyamide/Nylon) and flammability rating (UL94 V-0)
• Identical MSL rating (1 - Unlimited)

Distinguishing Characteristics: The substitute part differs only in product status (Active vs. Obsolete), packaging format (Tape & Reel vs. standard), and post-termination contact finish (Tin vs. Tin-Lead). These differences do not affect functional compatibility or electrical performance in equivalent applications.

Engineering Selection Recommendations

The TE Connectivity 5-794629-2 is the direct substitute for the obsolete 2-794629-2 connector header. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 2-794629-2 carries an obsolete designation, limiting availability for new production and long-term supply chain continuity. The substitute 5-794629-2 maintains active product status, ensuring ongoing availability and manufacturer support.

Compliance Certifications: The substitute part 5-794629-2 is RoHS Compliant, whereas the main part status is listed as Not applicable. This compliance improvement aligns with current regulatory requirements for electronic components in many jurisdictions and applications.

Electrical and Mechanical Equivalence: All critical parameters determining connector functionality remain identical between the two parts. The 22-position, 2-row configuration with 0.118" (3.00mm) pitch, surface mount right-angle mounting, shrouded 4-wall design, and solder termination are preserved. Voltage rating (250V), operating temperature range (-40°C ~ 105°C), and contact materials (brass with gold mating finish) are unchanged.

Contact Finish Variation: The substitute part features tin post-termination finish compared to tin-lead on the main part. Both finishes meet the specified 100.0µin (2.54µm) thickness requirement and provide equivalent solderability and electrical performance for board-level assembly.

Packaging Availability: The substitute is available in Tape & Reel (TR) packaging, offering advantages for automated assembly processes while maintaining identical component specifications.

Frequently Asked Questions (FAQ)

Q: Can the 5-794629-2 be used as a direct replacement for the 2-794629-2 in existing designs?

A: Yes. The 5-794629-2 is electrically and mechanically equivalent to the 2-794629-2. All critical parameters including connector type, position count, pitch spacing, mounting configuration, voltage rating, and operating temperature range are identical. The parts are interchangeable at the component level.

Q: What is the significance of the different contact finish (Tin vs. Tin-Lead) on the post termination?

A: Both tin and tin-lead finishes meet the specified thickness of 100.0µin (2.54µm) and provide equivalent solderability for PCB assembly. The tin finish on the substitute part reflects current manufacturing standards and environmental compliance practices. Functional performance in solder joint formation is equivalent.

Q: Why is the main part listed as obsolete?

A: The 2-794629-2 carries an obsolete product status, indicating that TE Connectivity has transitioned production to the active 5-794629-2 variant. Obsolete designation typically reflects manufacturer lifecycle decisions and the availability of improved or compliant alternatives.

Q: Does the RoHS Compliance difference affect component selection?

A: The substitute part 5-794629-2 is RoHS Compliant, while the main part status is Not applicable. For applications subject to RoHS regulations or customer requirements, the substitute part provides documented compliance. For applications without such requirements, both parts function identically.

Q: Are there packaging considerations when switching from 2-794629-2 to 5-794629-2?

A: The substitute part is available in Tape & Reel (TR) packaging format, which is standard for automated assembly processes. The main part packaging format is not specified in the available data. Tape & Reel packaging is compatible with pick-and-place equipment and offers handling advantages for high-volume production.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the 2-794629-2 and 5-794629-2 carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.

Q: Are the electrical specifications identical between the two parts?

A: Yes. Both parts share identical voltage rating (250V), operating temperature range (-40°C ~ 105°C), contact material (brass), mating contact finish (gold at 30.0µin / 0.76µm thickness), and current rating (varies by wire gauge). Electrical performance is equivalent.

Q: Can the 5-794629-2 be used in applications originally designed for the 2-794629-2?

A: Yes. The 5-794629-2 maintains full compatibility with applications designed for the 2-794629-2. All mechanical dimensions, electrical ratings, and functional characteristics are preserved. The substitute part is suitable for direct implementation in existing designs.
