Substitute Part Grouping Explanation

Substitution between the main part 794632-4 and the equivalent part 3-794632-4 is based on strict electrical and mechanical parameter alignment. Both parts share identical specifications across all critical functional parameters: connector type (Header), contact type (Male Pin), number of positions (4), row configuration (2 rows), mating pitch (0.118"/3.00mm), row spacing (0.118"/3.00mm), mounting method (Through Hole), shrouding design (Shrouded - 4 Wall), voltage rating (250V), operating temperature range (-40°C ~ 105°C), and material flammability rating (UL94 V-0).

The primary distinction between these parts is packaging format and regulatory compliance status. Part 3-794632-4 is supplied in Tray packaging with higher inventory availability (4930 pieces) and carries RoHS3 compliance certification, whereas the main part 794632-4 is non-RoHS compliant. Both parts maintain identical contact materials (Brass), insulation materials (Polyamide/Nylon), contact finishes (Gold mating surface), and termination methods (Press-Fit, Solder).

Key parameters determining substitution eligibility:

• Connector pitch and row spacing
• Number of positions and row count
• Contact type and material composition
• Mounting and shrouding configuration
• Voltage and temperature ratings
• Flammability certification

Parameter Comparison

Engineering Selection Recommendations

Both 794632-4 and 3-794632-4 are functionally equivalent rectangular connectors within the Micro MATE-N-LOK series and maintain active product status. Selection between these parts should be based on specific project requirements and regulatory compliance mandates.

For applications requiring RoHS3 compliance: Part 3-794632-4 is the appropriate selection, as it carries RoHS3 certification. This part is suitable for projects subject to European Union Restriction of Hazardous Substances regulations or customer specifications mandating RoHS compliance.

For applications without RoHS compliance requirements: Either part may be selected based on packaging preference and inventory availability. Part 794632-4 is available in standard packaging, while part 3-794632-4 is supplied in Tray packaging with significantly higher stock levels (4930 pieces versus 743 pieces).

Contact finish consideration: Part 3-794632-4 features Tin post finish, while part 794632-4 features Tin-Lead post finish. Both maintain identical contact finish thickness (100.0µin/2.54µm) and identical mating surface finish (Gold, 30.0µin/0.76µm). This variation does not affect electrical or mechanical compatibility.

All other electrical and mechanical parameters are identical between the two parts, including voltage rating (250V), operating temperature range (-40°C ~ 105°C), and UL94 V-0 flammability certification.

Frequently Asked Questions (FAQ)

Q: Are parts 794632-4 and 3-794632-4 electrically interchangeable?

A: Yes. Both parts are electrically interchangeable. They share identical voltage ratings (250V), operating temperature ranges (-40°C ~ 105°C), contact materials (Brass), and mating surface finishes (Gold). The post finish variation (Tin-Lead versus Tin) does not affect electrical performance or compatibility.

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

A: The primary differences are packaging format and regulatory compliance status. Part 3-794632-4 is supplied in Tray packaging and carries RoHS3 compliance certification. Part 794632-4 is non-RoHS compliant. Both parts are mechanically and electrically identical.

Q: Can I substitute 3-794632-4 for 794632-4 in an existing design?

A: Yes, part 3-794632-4 is a direct substitute for 794632-4. All mechanical dimensions, electrical specifications, and functional parameters are identical. If your application or customer requirements mandate RoHS compliance, part 3-794632-4 is the required selection.

Q: Does the Tray packaging of part 3-794632-4 affect its performance?

A: No. Packaging format does not affect connector performance, electrical characteristics, or mechanical function. Tray packaging is a distribution and handling format only. The connector itself is identical to the standard packaged version.

Q: Are the contact finishes compatible between these parts?

A: Yes. Part 794632-4 features Tin-Lead post finish, while part 3-794632-4 features Tin post finish. Both maintain identical contact finish thickness (100.0µin/2.54µm) and identical mating surface finish (Gold, 30.0µin/0.76µm). Both finishes are compatible with standard soldering and press-fit termination methods.

Q: Which part should I select for new designs?

A: For new designs, part 3-794632-4 is recommended due to RoHS3 compliance certification and higher inventory availability (4930 pieces). This part supports current regulatory requirements and provides better supply chain continuity.

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

A: Yes. Both parts are rated for identical operating temperature ranges of -40°C to 105°C and carry identical UL94 V-0 material flammability ratings, confirming suitability for the full specified temperature range.

Q: What is the significance of the "Micro MATE-N-LOK" series designation?

A: Micro MATE-N-LOK is the connector series designation from TE Connectivity AMP Connectors. Both parts belong to this series, confirming they share the same mechanical interface, mating pitch (0.118"/3.00mm), and shrouding design (Shrouded - 4 Wall). This series designation ensures compatibility with corresponding mating connectors and receptacles.
