Substitute Part Grouping Explanation

Substitution between the main part 794627-4 and the equivalent part 3-794627-4 is based on electrical and mechanical compatibility. Both parts share identical core specifications: 4-position header configuration, 0.118" (3.00mm) pitch in 2-row arrangement, surface mount right-angle mounting, shrouded 4-wall construction, solder termination with locking ramp fastening, and identical operating temperature range (-40°C ~ 105°C) and voltage rating (250V). Both maintain UL94 V-0 flammability rating and Moisture Sensitivity Level 2 (1 Year).

The primary distinction between these parts is packaging format and contact finish specification. The main part 794627-4 features Tin-Lead contact finish, while the substitute part 3-794627-4 features Tin contact finish. Additionally, 3-794627-4 is supplied in Tape & Reel (TR) packaging format and carries ROHS3 compliance, whereas 794627-4 is RoHS non-compliant. These differences do not affect electrical or mechanical interchangeability in applications where the contact finish material and packaging format are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both 794627-4 and 3-794627-4 are Active products from TE Connectivity and are electrically and mechanically interchangeable for applications requiring a 4-position, 0.118" (3.00mm) pitch surface mount right-angle header with shrouded construction and solder termination.

Selection between these parts should be based on specific project requirements:

794627-4 is appropriate for applications where Tin-Lead contact finish is acceptable and standard packaging is suitable. This part is RoHS non-compliant.

3-794627-4 is appropriate for applications requiring ROHS3 compliance and Tape & Reel packaging for automated assembly processes. The Tin contact finish provides an alternative to Tin-Lead plating while maintaining equivalent electrical performance and contact reliability.

Both parts maintain identical mechanical dimensions, electrical ratings, operating temperature range, and flammability certification. Selection should account for regulatory compliance requirements, assembly methodology, and contact finish material compatibility with mating components.

Frequently Asked Questions (FAQ)

Q: Are 794627-4 and 3-794627-4 electrically interchangeable?

A: Yes. Both parts are electrically interchangeable. They share identical electrical specifications including 250V voltage rating, operating temperature range of -40°C ~ 105°C, and current rating that varies by wire gauge. The contact finish difference (Tin-Lead versus Tin) does not affect electrical interchangeability.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The main part 794627-4 uses Tin-Lead contact finish, while the substitute part 3-794627-4 uses Tin contact finish. Both finishes provide equivalent contact reliability and electrical performance. The Tin finish in 3-794627-4 supports ROHS3 compliance, whereas Tin-Lead in 794627-4 does not.

Q: Can I use 3-794627-4 in place of 794627-4 in my design?

A: Yes, provided your application accepts Tin contact finish and ROHS3 compliance is not a requirement. The parts are mechanically and electrically identical in all other respects. Verify that your mating connector and assembly process are compatible with the Tin contact finish.

Q: What is the significance of the packaging difference?

A: The main part 794627-4 uses standard packaging, while 3-794627-4 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly processes and high-volume production. Standard packaging is suitable for manual assembly or lower-volume applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both 794627-4 and 3-794627-4 operate across the identical temperature range of -40°C ~ 105°C and maintain UL94 V-0 flammability rating across this range.

Q: What does ROHS3 compliance mean for 3-794627-4?

A: ROHS3 compliance indicates that 3-794627-4 meets the Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials including lead. The main part 794627-4 is RoHS non-compliant due to its Tin-Lead contact finish.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both 794627-4 and 3-794627-4 have Moisture Sensitivity Level 2 (1 Year), indicating identical handling and storage requirements.

Q: Can I mix 794627-4 and 3-794627-4 in the same assembly?

A: Yes, from an electrical and mechanical standpoint. However, best practice recommends using a single part number throughout a design to maintain consistency in contact finish, compliance status, and supply chain management.
