Key Parameters

Substitute Part Grouping Explanation

The substitute part 3-794624-4 is functionally equivalent to the main part 794624-4 based on the following critical parameters that determine substitutability:

Electrical Compatibility Parameters:

• Connector type, contact type, and pin configuration (4 positions, 2 rows)
• Pitch and row spacing (0.118" / 3.00mm)
• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)
• Contact material and shape (Brass, Square)

Mechanical Compatibility Parameters:

• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation material and color (Polyamide/Nylon, Black)

Distinguishing Factors: The primary differences between 794624-4 and 3-794624-4 are packaging format and contact finish specifications. Part 794624-4 is supplied in standard packaging with Tin-Lead contact finish, while 3-794624-4 is supplied in Tape & Reel (TR) packaging with Tin contact finish. Additionally, 3-794624-4 is RoHS3 compliant with MSL 2 (1 Year), whereas 794624-4 is RoHS non-compliant with MSL 1 (Unlimited).

Parameter Comparison

Engineering Selection Recommendations

Functional Equivalence: Parts 794624-4 and 3-794624-4 are functionally equivalent for board-to-cable/wire connector applications. Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, mounting configuration, and operating conditions.

Compliance Considerations: The 3-794624-4 substitute part carries RoHS3 compliance certification, making it suitable for applications subject to RoHS regulatory requirements. The original 794624-4 is RoHS non-compliant and should be selected only when RoHS compliance is not a design requirement.

Contact Finish Specification: The 794624-4 features Tin-Lead contact finish, while the 3-794624-4 features Tin contact finish. Both finishes are applied at identical thickness (100.0µin / 2.54µm) and provide equivalent electrical performance. Selection between these finishes depends on application-specific solderability and environmental exposure requirements.

Packaging and Moisture Sensitivity: The 794624-4 is supplied in standard packaging with MSL 1 (Unlimited moisture sensitivity level), indicating no moisture-related storage restrictions. The 3-794624-4 is supplied in Tape & Reel (TR) format with MSL 2 (1 Year), requiring controlled storage conditions. Packaging selection depends on manufacturing process requirements and inventory management protocols.

Product Status: Both parts maintain Active product status with TE Connectivity, ensuring continued availability and technical support.

Frequently Asked Questions (FAQ)

Q: Are 794624-4 and 3-794624-4 directly interchangeable in circuit design?

A: Yes. Both parts are functionally equivalent for circuit design purposes. They share identical electrical specifications including voltage rating (250V), operating temperature range (-40°C to 105°C), connector configuration (4 positions, 2 rows at 3.00mm pitch), and mechanical mounting characteristics (surface mount, right angle, shrouded 4-wall).

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

A: The primary differences are packaging format and regulatory compliance. The 794624-4 is supplied in standard packaging with RoHS non-compliant status and Tin-Lead contact finish. The 3-794624-4 is supplied in Tape & Reel (TR) packaging with RoHS3 compliance and Tin contact finish.

Q: Which part should be selected for RoHS-compliant applications?

A: The 3-794624-4 is RoHS3 compliant and must be selected for applications subject to RoHS regulatory requirements. The 794624-4 is RoHS non-compliant and is not suitable for RoHS-regulated applications.

Q: Does the Tape & Reel packaging of 3-794624-4 affect electrical performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tape & Reel (TR) packaging is a manufacturing and assembly convenience format that does not alter connector specifications or functionality.

Q: What is the significance of the different contact finishes (Tin-Lead vs. Tin)?

A: Both contact finishes are applied at identical thickness (100.0µin / 2.54µm) and provide equivalent electrical conductivity and contact resistance. The selection between Tin-Lead (794624-4) and Tin (3-794624-4) depends on application-specific solderability requirements and environmental exposure conditions. Tin finish is typically preferred in RoHS-compliant applications.

Q: Are there moisture sensitivity considerations when selecting between these parts?

A: Yes. The 794624-4 carries MSL 1 (Unlimited), indicating no moisture-related storage restrictions. The 3-794624-4 carries MSL 2 (1 Year), requiring controlled storage conditions with humidity management. Selection depends on manufacturing facility capabilities and inventory management protocols.

Q: Can 794624-4 be used as a substitute when 3-794624-4 is specified?

A: Substitution is possible only when RoHS compliance is not a design requirement. If RoHS3 compliance is specified, 794624-4 cannot be used as a substitute. For non-RoHS applications, 794624-4 is functionally equivalent.

Q: Can 3-794624-4 be used as a substitute when 794624-4 is specified?

A: Yes. The 3-794624-4 is functionally equivalent and provides enhanced compliance (RoHS3). It can be used as a direct substitute in all applications where 794624-4 is specified, provided that Tape & Reel packaging and MSL 2 storage requirements are compatible with manufacturing processes.
