Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 3-794627-2 are identified based on strict equivalence across critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Mandatory Matching Parameters:

• Series: Micro MATE-N-LOK
• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 2
• Number of Rows: 2
• Row Spacing - Mating: 0.118" (3.00mm)
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Insulation Height: 0.290" (7.37mm)
• Contact Shape: Square
• Contact Material: Brass
• Insulation Material: Polyamide (PA), Nylon
• Operating Temperature Range: -40°C ~ 105°C
• Voltage Rating: 250V
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black
• RoHS Status: ROHS3 Compliant
• Product Status: Active
• Packaging: Tape & Reel (TR)

Allowable Variation Parameters:

• Contact Finish - Mating: Tin or Gold
• Contact Finish Thickness - Mating: 100.0µin (2.54µm) or 30.0µin (0.76µm)
• Moisture Sensitivity Level (MSL): 2 (1 Year) or 1 (Unlimited)

The substitute part 3-794629-2 maintains all mandatory parameters while varying only in contact finish specifications and moisture sensitivity level, which are allowable variations within the Micro MATE-N-LOK connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 3-794627-2 and 3-794629-2 are Active product status connectors within the Micro MATE-N-LOK series. Both parts are ROHS3 compliant and carry UL94 V-0 material flammability certification, meeting regulatory requirements for general purpose applications.

The primary distinction between these parts is the contact finish specification on the mating surface. The 3-794627-2 features tin plating at 100.0µin (2.54µm) thickness, while the 3-794629-2 features gold plating at 30.0µin (0.76µm) thickness. Both finishes are applied to brass contact material and maintain equivalent electrical performance within the 250V voltage rating and -40°C to 105°C operating temperature range.

The 3-794629-2 offers improved moisture sensitivity characteristics with MSL 1 (Unlimited) compared to the 3-794627-2 MSL 2 (1 Year), providing extended shelf life and reduced handling constraints in storage and logistics environments.

Selection between these parts is determined by application-specific requirements regarding contact finish preference and moisture sensitivity requirements. Both parts maintain identical mechanical fit, electrical ratings, and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 3-794627-2 and 3-794629-2 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 2-position configuration, 0.118" (3.00mm) row spacing, 0.290" (7.37mm) insulation height, shrouded 4-wall construction, and surface mount right-angle mounting. They are mechanically interchangeable in board-to-cable/wire applications.

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

A: The 3-794627-2 uses tin plating at 100.0µin (2.54µm) on the mating contact surface. The 3-794629-2 uses gold plating at 30.0µin (0.76µm) on the mating contact surface. Both finishes are applied to brass base material and provide equivalent electrical conductivity within the connector's 250V voltage rating.

Q: Do these parts have the same electrical performance?

A: Yes. Both parts operate within the same voltage rating (250V), current rating (varies by wire gauge), and temperature range (-40°C to 105°C). Electrical performance is equivalent across both connector variants.

Q: What does the MSL rating difference mean?

A: MSL (Moisture Sensitivity Level) indicates storage and handling requirements. The 3-794627-2 has MSL 2 (1 Year), requiring controlled storage conditions with a one-year shelf life from manufacturing. The 3-794629-2 has MSL 1 (Unlimited), allowing indefinite storage without moisture control requirements. This affects logistics, warehousing, and component handling procedures.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 3-794627-2 and 3-794629-2 are ROHS3 compliant and carry UL94 V-0 material flammability certification, meeting regulatory requirements for electronic component applications.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, from a mechanical and electrical standpoint. Both parts maintain identical connector geometry, pin configuration, voltage rating, and temperature range. Selection between them depends on application-specific requirements for contact finish type and moisture sensitivity handling.

Q: What is the packaging format for both parts?

A: Both parts are supplied in Tape & Reel (TR) packaging format, standard for surface mount component distribution and automated assembly processes.
