TE Connectivity 794637-6 Rectangular Connector Header: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794637-6 is a surface mount rectangular connector header from the Micro MATE-N-LOK series. This component functions as a board-to-cable/wire interface with 6 positions arranged in 2 rows at 3.00mm pitch. The connector features shrouded 4-wall construction with solder termination and locking ramp fastening. The part maintains Active product status and is suitable for general purpose applications requiring reliable interconnection in temperature ranges from -40°C to 105°C.

Identifying equivalent and substitute parts becomes necessary when addressing packaging requirements, compliance specifications, or inventory availability while maintaining identical electrical and mechanical functionality.

Substitute Part Grouping Explanation

Substitution between the main part 794637-6 and the equivalent part 3-794637-6 is based on identical electrical and mechanical specifications. Both parts share the same connector architecture, contact configuration, pitch dimensions, and performance ratings. The primary distinction between these parts lies in packaging format and compliance certifications.

The substitution logic is determined by the following critical parameters that must remain constant:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 6
• Number of Rows: 2
• Pitch - Mating: 0.118" (3.00mm)
• Row Spacing - Mating: 0.118" (3.00mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Locking Ramp
• Voltage Rating: 250V
• Operating Temperature: -40°C ~ 105°C
• Material Flammability Rating: UL94 V-0

Parameter Comparison

Engineering Selection Recommendations

The 794637-6 and 3-794637-6 are electrically and mechanically interchangeable for all functional applications. Both parts maintain identical connector specifications, contact configurations, and performance ratings across the full operating temperature range.

Selection between these parts should be based on the following criteria:

794637-6 (Bulk Packaging): This configuration is appropriate for applications where RoHS non-compliance is acceptable and REACH-affected materials are permitted. The bulk packaging format suits applications with lower volume requirements or where tape and reel handling is not necessary.

3-794637-6 (Tape & Reel Packaging): This configuration is appropriate for applications requiring ROHS3 compliance and REACH-unaffected material status. The tape and reel packaging format is suitable for automated assembly processes and high-volume production environments. This part is the preferred selection for applications subject to European Union regulatory requirements or customer specifications mandating RoHS3 compliance.

Both parts are Active products from TE Connectivity and maintain equivalent reliability and performance characteristics. The contact finish difference on the post (Tin-Lead versus Tin) does not affect functional compatibility, as both finishes provide equivalent solder joint performance and reliability.

Frequently Asked Questions (FAQ)

Q: Are the 794637-6 and 3-794637-6 parts electrically identical?

A: Yes. Both parts share identical electrical specifications including voltage rating (250V), operating temperature range (-40°C to 105°C), contact material (Brass), contact finish on mating surfaces (Gold at 15.0µin thickness), and current rating characteristics based on wire gauge.

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

A: The primary differences are packaging format and regulatory compliance status. The 794637-6 is supplied in bulk packaging and is RoHS non-compliant with REACH-affected material status. The 3-794637-6 is supplied in Tape & Reel (TR) packaging and is ROHS3 compliant with REACH-unaffected material status.

Q: Can I use 3-794637-6 as a direct replacement for 794637-6 in my assembly?

A: Yes, the 3-794637-6 is a direct functional replacement for 794637-6. The connector specifications, mounting characteristics, and performance parameters are identical. The tape and reel packaging format is compatible with standard automated pick-and-place assembly equipment.

Q: Does the contact finish difference (Tin-Lead versus Tin) affect compatibility?

A: No. The contact finish difference on the post (Tin-Lead in 794637-6 versus Tin in 3-794637-6) does not affect functional compatibility or solder joint reliability. Both finishes provide equivalent performance in solder termination applications.

Q: Which part should I select for new designs?

A: For new designs, the 3-794637-6 is the appropriate selection. This part offers ROHS3 compliance and REACH-unaffected material status, aligning with current regulatory requirements and industry standards. The tape and reel packaging also supports efficient automated assembly processes.

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

A: Yes. Both the 794637-6 and 3-794637-6 are rated for operation from -40°C to 105°C and maintain identical performance across this entire temperature range.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating unlimited shelf life without moisture exposure precautions. This simplifies inventory management and storage requirements for both part numbers.

Q: Can I mix 794637-6 and 3-794637-6 parts in the same production batch?

A: Yes. From a functional and mechanical perspective, these parts are interchangeable and can be used together in the same assembly. However, if your application or customer specifications require consistent RoHS compliance status across all components, you should standardize on a single part number.
