TE Connectivity 2-794630-4 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-794630-4 is a Micro MATE-N-LOK series rectangular connector header designed for through-hole mounting applications. This 24-position, 2-row connector features a 0.118" (3.00mm) pitch and is rated for 250V operation across a temperature range of -40°C to 105°C. The connector utilizes press-fit and solder termination methods with shrouded 4-wall construction and locking ramp fastening. The part is currently active in production status with 660 pieces available in inventory. Identifying equivalent substitute parts is necessary when the original part number becomes unavailable, when alternative packaging formats are required, or when compliance requirements differ between applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criteria for the 2-794630-4 are:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (24)
• Number of rows (2)
• Pitch - mating (0.118" / 3.00mm)
• Row spacing - mating (0.118" / 3.00mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination methods (Press-Fit, Solder)
• Fastening type (Locking Ramp)
• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)
• Series designation (Micro MATE-N-LOK)

The substitute part 5-794630-4 maintains full equivalence across all critical electrical and mechanical parameters. The primary difference between the main part and its substitute is the packaging format and contact finish specification on the mating surface, along with RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 5-794630-4 serves as a direct functional equivalent to the 2-794630-4 across all critical electrical and mechanical parameters. Both parts are manufactured by TE Connectivity within the Micro MATE-N-LOK series and maintain identical connector geometry, pitch spacing, mounting configuration, and electrical ratings.

Compliance Considerations:

The 5-794630-4 is ROHS3 compliant, whereas the 2-794630-4 is RoHS non-compliant. Applications subject to RoHS regulations or requiring lead-free components should specify the 5-794630-4. The contact finish on the mating surface differs between the two parts: the 2-794630-4 uses Tin-Lead while the 5-794630-4 uses Tin. Both finishes meet the same thickness specification of 100.0µin (2.54µm).

Packaging and Availability:

The 5-794630-4 is supplied in tray packaging with significantly higher inventory availability (4212 pieces) compared to the 2-794630-4 (660 pieces). Selection between these parts should consider packaging requirements for automated assembly processes and supply chain continuity.

Both parts maintain identical product status as active components and are suitable for general-purpose applications requiring 24-position through-hole header connectors with 3.00mm pitch spacing.

Frequently Asked Questions (FAQ)

Q: Are the 2-794630-4 and 5-794630-4 mechanically interchangeable?

A: Yes. Both parts maintain identical mechanical specifications including connector type, position count, row configuration, pitch spacing, mounting type, shrouding design, and fastening mechanism. They are mechanically interchangeable in all applications.

Q: What is the difference in contact finish between these two parts?

A: The 2-794630-4 features Tin-Lead contact finish on the mating surface, while the 5-794630-4 uses Tin finish. Both finishes are applied at 100.0µin (2.54µm) thickness. The post contact finish differs similarly: Tin-Lead for the 2-794630-4 and Tin for the 5-794630-4. These differences do not affect electrical performance or mechanical compatibility.

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

A: The 5-794630-4 is ROHS3 compliant and must be specified for applications subject to RoHS regulations. The 2-794630-4 is RoHS non-compliant and is not suitable for such applications.

Q: Does packaging format affect connector performance?

A: No. The 2-794630-4 is supplied in bulk packaging while the 5-794630-4 is supplied in tray packaging. Packaging format does not affect electrical or mechanical performance. Selection should be based on assembly process requirements and handling procedures.

Q: Are both parts rated for the same voltage and temperature range?

A: Yes. Both the 2-794630-4 and 5-794630-4 are rated for 250V operation and function across the identical temperature range of -40°C to 105°C. They maintain the same UL94 V-0 flammability rating and moisture sensitivity level.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The 5-794630-4 can be substituted for the 2-794630-4 in existing designs without modification. All critical electrical and mechanical parameters are equivalent. Designers should verify RoHS compliance requirements for their specific application before selecting between these parts.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge for both parts. Specific current capacity must be determined based on the wire gauge used in the application and referenced against TE Connectivity technical documentation.
