Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers within the TE Connectivity Micro MATE-N-LOK series is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact type (Male Pin)
• Number of positions (8)
• Number of rows (2)
• Pitch spacing (0.118" / 3.00mm)
• Row spacing (0.118" / 3.00mm)
• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Insulation height (0.290" / 7.37mm)
• Contact shape (Square)
• Termination method (Solder)
• Fastening type (Locking Ramp)

Material & Environmental Parameters:

• Contact material (Brass)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)
• Insulation color (Black)
• MSL rating (2)

The substitute part 3-794627-8 maintains full equivalence across all electrical and mechanical parameters. Differentiation exists only in packaging format and compliance certifications, which do not affect functional interchangeability in the application.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (794627-8): The TE Connectivity 794627-8 is suitable for applications where bulk packaging is acceptable and RoHS non-compliance does not present regulatory constraints. This part maintains Active product status and is available in inventory quantities of 788 pieces.

Substitute Part Selection (3-794627-8): The 3-794627-8 is the direct functional equivalent and is recommended for applications requiring ROHS3 compliance. This variant is supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly processes. Inventory availability is significantly higher at 9996 pieces. The contact finish differs from the primary part (Tin versus Tin-Lead), which does not affect electrical or mechanical compatibility but may be relevant for specific soldering process requirements.

Compliance Considerations: Selection between these parts should be based on regulatory requirements applicable to the end application. The 3-794627-8 provides ROHS3 compliance, while the 794627-8 does not. Both parts maintain identical electrical performance, mechanical fit, and thermal characteristics across the specified operating range.

Packaging Considerations: The choice between bulk and Tape & Reel packaging depends on assembly methodology. Tape & Reel format (3-794627-8) is optimized for high-volume automated pick-and-place assembly, while bulk packaging (794627-8) is suitable for manual assembly or lower-volume applications.

Frequently Asked Questions (FAQ)

Q: Are the 794627-8 and 3-794627-8 electrically interchangeable?

A: Yes. Both parts are electrically identical. They share the same voltage rating (250V), operating temperature range (-40°C ~ 105°C), contact configuration (8 positions, 2 rows, 3.00mm pitch), and contact material (Brass). The contact finish difference (Tin-Lead versus Tin) does not affect electrical performance.

Q: What is the difference between these two parts?

A: The primary differences are packaging format and RoHS compliance status. The 794627-8 is supplied in bulk packaging and is RoHS non-compliant. The 3-794627-8 is supplied in Tape & Reel (TR) packaging and is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can I use 3-794627-8 in place of 794627-8 in my design?

A: Yes. The 3-794627-8 is a direct substitute. It maintains identical mechanical fit, electrical performance, and thermal characteristics. If your application or supply chain requires ROHS3 compliance, the 3-794627-8 is the appropriate selection.

Q: Which part should I specify for automated assembly?

A: The 3-794627-8 in Tape & Reel (TR) packaging is the standard format for automated pick-and-place assembly processes. This packaging format is optimized for high-speed component placement equipment.

Q: Are there any soldering process differences between these parts?

A: The contact finish differs between the parts (Tin-Lead for 794627-8 versus Tin for 3-794627-8). Both finishes are compatible with standard solder reflow processes. Consult your soldering process specifications if you have specific requirements for lead content or solder alloy compatibility.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts have an MSL rating of 2 with a 1-year shelf life. This indicates moderate moisture sensitivity. Storage in controlled humidity environments and proper handling procedures are required to maintain component reliability.

Q: Can I mix 794627-8 and 3-794627-8 in the same production run?

A: Yes. Both parts are functionally identical and can be used interchangeably in the same application. However, mixing packaging formats may complicate inventory management and assembly process control.

Q: What is the current rating for these connectors?

A: The current rating varies by wire gauge. Refer to the mating connector specifications and wire gauge selection tables provided by TE Connectivity for specific current capacity calculations.

Q: Are these connectors suitable for my application temperature range?

A: Both parts operate across -40°C to 105°C. Confirm that your application requirements fall within this range. If your application requires operation outside this temperature window, alternative connector series must be evaluated.
