Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TE Connectivity 794636-2 and its direct substitute 3-794636-2 are functionally equivalent components within the Micro MATE-N-LOK series. Both parts maintain Active product status and satisfy identical electrical, mechanical, and environmental specifications.

Packaging Consideration:

The main part 794636-2 is supplied in bulk packaging format, while the substitute 3-794636-2 is supplied in Tape & Reel (TR) format. Selection between these two part numbers should be based on manufacturing process requirements and assembly line automation compatibility. Tape & Reel packaging is standard for automated surface mount assembly operations, whereas bulk packaging may be suitable for manual assembly or lower-volume production environments.

Compliance Differentiation:

The substitute part 3-794636-2 carries ROHS3 Compliant certification, whereas the main part 794636-2 lists RoHS Status as Not applicable. This distinction indicates that the substitute part meets current RoHS3 regulatory requirements. Organizations subject to RoHS3 compliance mandates should prioritize the substitute part 3-794636-2.

Contact Finish Specification:

The main part features Tin-Lead contact finish on both mating and post surfaces. The substitute part features Tin contact finish on both mating and post surfaces. Both finishes maintain identical thickness specifications of 100.0µin (2.54µm). The Tin finish in the substitute part aligns with lead-free manufacturing initiatives while maintaining functional equivalence for solder termination applications.

Inventory and Availability:

The substitute part 3-794636-2 maintains significantly higher inventory levels (16,947 pieces) compared to the main part 794636-2 (694 pieces), indicating superior supply chain availability for the substitute designation.

Frequently Asked Questions (FAQ)

Q: Are the 794636-2 and 3-794636-2 interchangeable in circuit design?

A: Yes. Both parts maintain identical electrical ratings (250V, -40°C ~ 105°C operating range), mechanical dimensions (2 positions, 2 rows, 0.118" row spacing), and connector interface specifications. They are direct functional equivalents for circuit design purposes.

Q: What is the difference between Tape & Reel and bulk packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, designed for automated pick-and-place assembly equipment. Bulk packaging supplies components in loose or bagged format, suitable for manual assembly or lower-volume operations. The functional component specifications remain identical; only the delivery format differs.

Q: Why does the substitute part carry ROHS3 compliance while the main part does not?

A: The RoHS3 Compliant designation on part 3-794636-2 indicates that this variant meets current European Union Restriction of Hazardous Substances Directive requirements. The main part 794636-2 lists RoHS Status as Not applicable, suggesting it may have been released prior to or outside the scope of RoHS3 regulatory requirements. For applications requiring RoHS3 compliance documentation, the substitute part 3-794636-2 is the appropriate selection.

Q: Does the Tin contact finish differ functionally from Tin-Lead finish?

A: Both contact finishes maintain identical thickness specifications (100.0µin / 2.54µm) and are suitable for solder termination. The Tin finish in the substitute part represents a lead-free alternative that aligns with modern manufacturing standards while maintaining equivalent electrical and mechanical performance for this connector application.

Q: Can I use the substitute part in existing designs specified for 794636-2?

A: Yes. The substitute part 3-794636-2 maintains full mechanical and electrical equivalence across all critical parameters including connector type, position count, row spacing, mounting method, operating temperature range, and voltage rating. Direct substitution is supported without design modification.

Q: Which part should I select for new designs?

A: For new designs, the substitute part 3-794636-2 is the recommended selection based on superior inventory availability, ROHS3 compliance certification, and lead-free contact finish specifications. The Tape & Reel packaging format is standard for modern surface mount assembly processes.

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

A: No. Both parts operate across the identical temperature range (-40°C ~ 105°C) and maintain the same voltage rating (250V). Current rating specifications are identical (Varies by Wire Gauge). Thermal and electrical performance characteristics are equivalent.
