Key Differentiators: The primary differences between these parts are packaging format and contact finish specifications. Part 1-794630-2 features Tin-Lead contact finish, while part 4-794630-2 features Tin contact finish. Additionally, part 4-794630-2 is supplied in Tray packaging with higher inventory availability (2520 pieces) and carries RoHS3 compliance, whereas part 1-794630-2 is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Part 1-794630-2 Selection Criteria: Select part 1-794630-2 when Tin-Lead contact finish is specifically required by design specifications or when RoHS non-compliance is acceptable for the application. This part maintains active production status and is suitable for general-purpose board-to-cable/wire connector applications.

Part 4-794630-2 Selection Criteria: Select part 4-794630-2 when RoHS3 compliance is mandated by procurement or regulatory requirements. This substitute part carries identical electrical and mechanical specifications while offering improved environmental compliance through Tin contact finish instead of Tin-Lead. The higher inventory availability (2520 pieces versus 743 pieces) and Tray packaging format provide additional supply chain advantages. Both parts maintain UL94 V-0 flammability rating and identical operating parameters.

Compliance Considerations: Applications requiring RoHS3 compliance must utilize part 4-794630-2. Applications with no compliance requirements or those specifically requiring Tin-Lead finish may utilize part 1-794630-2. Both parts are rated for identical voltage (250V) and temperature ranges (-40°C to 105°C), ensuring functional interchangeability within compliant applications.

Frequently Asked Questions (FAQ)

Q: Are parts 1-794630-2 and 4-794630-2 electrically interchangeable?

A: Yes. Both parts feature identical electrical specifications including 250V voltage rating, -40°C to 105°C operating temperature range, 12-position configuration with 0.118" (3.00mm) pitch, and identical contact materials and finishes thickness. The contact finish composition differs (Tin-Lead versus Tin), but both finishes provide equivalent electrical performance for this connector class.

Q: What is the primary difference between these substitute parts?

A: The primary differences are contact finish composition and RoHS compliance status. Part 1-794630-2 uses Tin-Lead finish and is RoHS non-compliant. Part 4-794630-2 uses Tin finish and is RoHS3 compliant. Additionally, part 4-794630-2 is supplied in Tray packaging with higher inventory availability.

Q: Are these parts mechanically compatible with the same mating connectors?

A: Yes. Both parts feature identical mechanical specifications including 0.118" (3.00mm) pitch spacing, 2-row configuration with 0.118" (3.00mm) row spacing, shrouded 4-wall design, through-hole mounting, and locking ramp fastening. They are mechanically interchangeable with the same mating connectors.

Q: Which part should be selected for new designs?

A: Part 4-794630-2 is recommended for new designs due to RoHS3 compliance, which aligns with current environmental regulations and procurement standards. This part maintains all electrical and mechanical specifications of the original part while offering improved compliance status.

Q: Does the Tin versus Tin-Lead contact finish affect soldering or press-fit performance?

A: Both contact finishes are specified at identical thickness (100.0µin / 2.54µm) and are suitable for both press-fit and solder termination methods. The finish composition does not affect termination compatibility for this connector class.

Q: What is the packaging difference between these parts?

A: Part 1-794630-2 packaging is not specified in the documentation. Part 4-794630-2 is supplied in Tray packaging format. Verify packaging requirements with procurement specifications before selection.

Q: Are both parts currently in production?

A: Yes. Both parts maintain Active product status. Part 1-794630-2 has 743 pieces in stock inventory, while part 4-794630-2 has 2520 pieces in stock inventory, providing greater availability for immediate procurement needs.
