• Insulation material (Polyamide/Nylon)
• Series designation (Mini-Universal MATE-N-LOK)

The substitute part 1-794374-2 maintains full equivalence across all mechanical, electrical, and functional parameters. Differences in product status, RoHS compliance, and packaging do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-794374-1 is a direct substitute for the obsolete 794374-2 connector header. Both parts maintain identical mechanical and electrical specifications across all critical parameters including connector type, contact configuration, mounting orientation, shrouding, termination method, and fastening mechanism.

Product Status Consideration: The 794374-2 is classified as obsolete, while the 1-794374-1 maintains active product status. This distinction makes the 1-794374-1 the appropriate selection for new designs, production continuity, and long-term supply chain reliability.

Compliance Consideration: The 1-794374-1 achieves ROHS3 compliance, whereas the 794374-2 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 1-794374-1 provides the necessary compliance certification.

Contact Finish Consideration: The 794374-2 specifies Tin-Lead post finish, while the 1-794374-1 specifies Tin post finish. Both finishes maintain the required contact finish thickness of 150.0µin (3.81µm) and are compatible with the gold-plated mating surface. The Tin finish in the 1-794374-1 aligns with modern lead-free manufacturing standards.

Availability Consideration: The 1-794374-1 is available in bulk packaging with significantly higher inventory levels (3547 pieces) compared to the 794374-2 (912 pieces), supporting production requirements and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1-794374-1 be used as a direct replacement for the 794374-2 in existing designs?

A: Yes. The 1-794374-1 is mechanically and electrically equivalent to the 794374-2. All critical parameters including connector type, contact configuration, mounting type, shrouding, termination method, and electrical ratings are identical. The parts are interchangeable in applications where the 794374-2 was originally specified.

Q: What is the difference between the Tin-Lead finish on the 794374-2 and the Tin finish on the 1-794374-1?

A: Both finishes maintain the same contact finish thickness of 150.0µin (3.81µm) at the post. The Tin finish on the 1-794374-1 represents a lead-free alternative that complies with modern manufacturing standards and RoHS regulations. Both finishes are compatible with the gold-plated mating surface and provide equivalent electrical performance.

Q: Why is the 794374-2 listed as obsolete?

A: The 794374-2 has been superseded by the 1-794374-1 in the TE Connectivity product line. The 1-794374-1 offers improved compliance certifications, lead-free contact finishes, and active product status with better supply chain availability.

Q: Are there any packaging differences between the 794374-2 and 1-794374-1?

A: The 794374-2 packaging is not specified in the technical data. The 1-794374-1 is available in bulk packaging. Packaging format does not affect the electrical or mechanical performance of the connector header itself.

Q: What is the operating temperature range for both parts?

A: Both the 794374-2 and 1-794374-1 operate across the identical temperature range of -20°C to 105°C. This specification applies to all environmental and thermal performance considerations.

Q: Are both parts rated for the same voltage?

A: Yes. Both the 794374-2 and 1-794374-1 are rated for 600VAC, ensuring equivalent electrical performance in applications requiring this voltage specification.

Q: What does the UL94 V-0 flammability rating indicate?

A: The UL94 V-0 rating indicates that both parts meet the highest flammability classification under UL94 standards. This certification applies to the insulation material (Polyamide/Nylon) and confirms compliance with fire safety requirements for electrical components.

Q: Can the 1-794374-1 be used in applications originally designed for the 794374-2 without circuit board modifications?

A: Yes. The 1-794374-1 maintains identical mechanical dimensions, mounting type (through-hole, right-angle), contact post length (0.145" / 3.68mm), and insulation height (0.225" / 5.72mm). No circuit board modifications are required for substitution.
