Both components maintain UL94 V-0 flammability rating and EAR99 export classification.

Contact Finish Distinction:

The 794633-6 features tin-lead contact finish, while the 3-794633-6 utilizes tin contact finish. Both maintain 100.0µin (2.54µm) finish thickness. This distinction reflects the regulatory shift toward lead-free materials in electronic components.

Packaging Format:

The main part is supplied in bulk packaging, while the substitute is available in Tape & Reel (TR) format. This packaging difference accommodates automated assembly processes and high-volume production environments.

Moisture Sensitivity:

Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 3-794633-6 directly replace the 794633-6 in existing designs?

A: Yes. The 3-794633-6 maintains full mechanical and electrical equivalence to the 794633-6. All critical parameters including pitch spacing, row configuration, voltage rating, temperature range, and contact specifications are identical. The substitute is suitable for direct replacement in board-to-cable/wire connection applications.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: The 794633-6 uses tin-lead finish, while the 3-794633-6 uses tin finish. Both finishes provide equivalent electrical conductivity and contact reliability at the specified 250V rating and -40°C to 105°C operating range. The tin finish in the substitute reflects compliance with lead-free material requirements under ROHS3 standards.

Q: Does the Tape & Reel packaging of the 3-794633-6 affect compatibility?

A: No. Tape & Reel packaging is a supply format that facilitates automated pick-and-place assembly. The physical connector dimensions, electrical characteristics, and mechanical interface remain unchanged. The packaging format does not affect the connector's functional performance or compatibility with mating components.

Q: Why is the 794633-6 listed as obsolete?

A: The 794633-6 has been superseded by the 3-794633-6 in the product line. The substitute part offers improved regulatory compliance (ROHS3 compliant, REACH Unaffected) and lead-free contact finish, aligning with current industry standards and environmental regulations.

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

A: No. Both components operate across the identical temperature range of -40°C to 105°C and maintain the same 250V voltage rating. Current rating capability is determined by wire gauge in both cases. Electrical performance and thermal characteristics are equivalent.

Q: What is the inventory status for the substitute part?

A: The 3-794633-6 has 791 pieces in stock as new original inventory. The main part 794633-6 has 806 pieces available. Both parts are available for immediate procurement.

Q: Does the locking ramp fastening mechanism function identically in both parts?

A: Yes. Both the 794633-6 and 3-794633-6 incorporate locking ramp fastening and board lock features. The mechanical engagement and retention characteristics are identical across both components.

Q: Are both parts suitable for general-purpose applications?

A: Yes. Both components are designated for general-purpose applications. The 6-position, 2-row configuration with 0.118" (3.00mm) pitch and shrouded 4-wall design accommodates standard board-to-cable/wire interconnection requirements.
