Engineering Selection Recommendations

For New Designs and Active Production:

The substitute part 3-794625-4 is the appropriate selection for new designs and ongoing production applications. This part maintains complete electrical and mechanical compatibility with the original 794625-4 while offering the following advantages:

• Active Product Status: The substitute part is actively manufactured and supported, ensuring long-term availability and supply chain continuity.
• RoHS3 Compliance: The substitute part meets RoHS3 compliance requirements, satisfying regulatory mandates for new product development in regulated markets.
• Lead-Free Post Finish: The substitute part features tin post finish, eliminating lead content and aligning with environmental and regulatory standards.
• Standardized Packaging: Tape & Reel packaging supports automated assembly processes and reduces handling costs.

For Legacy System Maintenance:

The original 794625-4 remains functionally equivalent for maintenance and repair of existing systems where RoHS compliance is not mandated. The tin-lead post finish of the original part does not affect mating performance or electrical characteristics.

Contact Finish Consideration:

The post contact finish variation (tin-lead versus tin) does not impact electrical performance or mechanical compatibility. Both finishes provide equivalent solder joint reliability and contact resistance characteristics for this connector application.

Frequently Asked Questions (FAQ)

Q: Are the 794625-4 and 3-794625-4 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including voltage rating (250V), operating temperature range (-40°C ~ 105°C), contact material (brass), and mating contact finish (gold). Electrical performance is equivalent.

Q: Are the 794625-4 and 3-794625-4 mechanically interchangeable?

A: Yes. Both parts have identical mechanical specifications including pitch (0.118" / 3.00mm), position count (4), row configuration (2 rows), mounting type (surface mount right angle), shrouding design (shrouded 4-wall), and board lock feature. Direct mechanical substitution is supported.

Q: What is the significance of the contact finish difference (tin-lead versus tin)?

A: The post contact finish difference does not affect connector performance. Both tin-lead and tin finishes provide equivalent solder joint reliability and contact resistance. The tin finish of the substitute part reflects compliance with lead-free manufacturing standards.

Q: Why is the original 794625-4 marked as obsolete?

A: Product obsolescence reflects TE Connectivity's transition to active manufacturing of the 3-794625-4 variant. The substitute part offers improved compliance certifications and standardized packaging while maintaining complete functional equivalence.

Q: What packaging differences exist between these parts?

A: The original 794625-4 packaging is not specified in available documentation. The substitute part 3-794625-4 is supplied in Tape & Reel (TR) packaging, which supports automated assembly processes and is standard for high-volume production applications.

Q: Is the 3-794625-4 suitable for applications requiring RoHS compliance?

A: Yes. The substitute part 3-794625-4 is RoHS3 compliant, meeting regulatory requirements for products marketed in regions with RoHS mandates. The original 794625-4 is RoHS non-compliant.

Q: Can the 3-794625-4 be used as a direct replacement in existing designs?

A: Yes. The substitute part provides complete electrical and mechanical compatibility with the original 794625-4. No design modifications are required for direct substitution in existing applications.

Q: Are there any inventory or lead time considerations?

A: The substitute part 3-794625-4 is actively manufactured with higher documented inventory levels (1548 pcs) compared to the obsolete original part (1048 pcs). Active production status ensures improved lead time and supply chain reliability.
