• Shrouding configuration (Shrouded - 4 Wall)
• Connector type (Header)
• Contact type (Male Pin)
• Insulation height (0.290" / 7.37mm)
• Operating temperature range (-40°C ~ 105°C)
• Voltage rating (250V)
• Material flammability rating (UL94 V-0)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Contact material (Brass)
• Insulation material (Polyamide / Nylon)
• Features (Board Lock)

The substitute part 3-794622-2 maintains full electrical and mechanical compatibility with the main part number 794622-2 across all specified parameters. The primary distinction between these parts is packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-794622-2 is the direct functional equivalent of the obsolete 794622-2. Both parts maintain identical electrical and mechanical specifications across all critical parameters, including connector geometry, contact configuration, temperature rating, voltage rating, and material compliance.

Product Status Consideration: The 794622-2 is classified as obsolete, while 3-794622-2 maintains active product status. This distinction indicates that 3-794622-2 is the current production equivalent and is the appropriate selection for new designs and ongoing procurement requirements.

Compliance Status: Both parts are RoHS compliant and carry UL94 V-0 flammability certification. The 3-794622-2 is designated as RoHS Compliant (current standard), while the 794622-2 is ROHS3 Compliant (legacy designation). Both meet current regulatory requirements.

Contact Finish Difference: The primary technical distinction is the post contact finish. The 794622-2 uses Tin-Lead finish, while 3-794622-2 uses Tin finish. This change reflects industry transition toward lead-free manufacturing practices and does not affect functional compatibility or performance within the specified operating parameters.

Packaging Consideration: The 794622-2 is supplied in bulk packaging, while 3-794622-2 is supplied in Tape & Reel format. Packaging selection depends on manufacturing process requirements and volume considerations but does not affect component functionality.

Frequently Asked Questions (FAQ)

Q: Can 3-794622-2 be used as a direct replacement for 794622-2 in existing designs?

A: Yes. The 3-794622-2 is electrically and mechanically equivalent to 794622-2 across all specified parameters. Both connectors maintain identical row spacing (0.118" / 3.00mm), insulation height (0.290" / 7.37mm), operating temperature range (-40°C to 105°C), voltage rating (250V), and mounting configuration. The parts are functionally interchangeable.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: The contact finish difference reflects manufacturing process evolution. The 794622-2 uses Tin-Lead finish, while 3-794622-2 uses Tin finish. Both finishes provide equivalent electrical performance and contact reliability within the specified operating parameters. The Tin finish in 3-794622-2 aligns with lead-free manufacturing standards.

Q: Why is 794622-2 classified as obsolete?

A: The 794622-2 is obsolete because 3-794622-2 is the current production equivalent. TE Connectivity has transitioned to 3-794622-2 as the active part number for this connector configuration. New designs should specify 3-794622-2.

Q: Does packaging format affect component performance?

A: No. The difference between bulk packaging (794622-2) and Tape & Reel packaging (3-794622-2) is a supply format distinction only. Both packaging formats contain identical components with identical electrical and mechanical specifications. Packaging selection is determined by manufacturing process requirements and volume needs.

Q: Are both parts RoHS compliant?

A: Yes. Both 794622-2 and 3-794622-2 are RoHS compliant. The 794622-2 carries ROHS3 Compliant designation, while 3-794622-2 carries RoHS Compliant designation. Both meet current regulatory requirements for restricted substance compliance.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture control requirements. These connectors do not require special moisture-sensitive device handling procedures.

Q: Can these connectors be used in applications requiring UL94 V-0 flammability compliance?

A: Yes. Both 794622-2 and 3-794622-2 carry UL94 V-0 material flammability certification, meeting requirements for applications with strict flammability specifications.
