Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors in the Micro MATE-N-LOK series is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (2)
• Number of rows (2)
• Row spacing (0.118" / 3.00mm)
• Mounting configuration (Surface Mount, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Fastening mechanism (Locking Ramp)

Electrical Compatibility:

• Operating temperature range (-40°C ~ 105°C)
• Voltage rating (250V)
• Contact finish specifications (Gold mating surface)
• Material flammability rating (UL94 V-0)

Termination Compatibility:

• Solder termination method
• Insulation material (Polyamide/Nylon)
• Insulation height (0.290" / 7.37mm)

The substitute part 3-794629-2 maintains full compatibility across all critical parameters while differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). Minor variation in post contact finish (Tin versus Tin-Lead) does not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-794629-2 is a direct functional equivalent to the obsolete 794629-2 connector. Selection between these parts is determined by application requirements and supply chain considerations:

Use 794629-2 (Main Part):

• Existing inventory applications requiring bulk packaging format
• Legacy system maintenance where original part specification is mandated
• Applications where Tin-Lead post finish is specifically required

Use 3-794629-2 (Substitute):

• New designs and production builds requiring active product status
• Applications requiring ROHS3 compliance certification
• Supply chain scenarios where Tape & Reel packaging is preferred for automated assembly
• Long-term product lifecycle support and availability assurance

Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical mechanical, electrical, and thermal specifications. The substitute part offers superior compliance status (ROHS3 Compliant versus Not applicable) and active product availability, making it the preferred selection for forward-looking applications.

Frequently Asked Questions (FAQ)

Q: Can 3-794629-2 be used as a direct replacement for 794629-2 in existing designs?

A: Yes. The 3-794629-2 is a direct functional equivalent. All critical parameters including connector type, position count, row spacing, mounting configuration, shrouding, termination method, operating temperature range, and voltage rating are identical. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the Tin-Lead finish on 794629-2 and the Tin finish on 3-794629-2?

A: Both finishes meet the 100.0µin (2.54µm) thickness specification for post contacts. Tin finish on 3-794629-2 represents a lead-free alternative that complies with ROHS3 requirements. Both finishes provide equivalent solder joint reliability and electrical performance in the specified operating temperature range.

Q: Why is 794629-2 classified as Obsolete while 3-794629-2 is Active?

A: Product status reflects manufacturer lifecycle management. The 3-794629-2 represents the current active production variant in the Micro MATE-N-LOK series. The 794629-2 remains available from existing inventory but is no longer in active production. For new designs and long-term supply assurance, 3-794629-2 is the recommended selection.

Q: Does the Tape & Reel packaging of 3-794629-2 affect compatibility?

A: No. Packaging format (Tape & Reel versus bulk) is a supply and assembly consideration only. It does not affect the connector's mechanical fit, electrical performance, or functional compatibility. Tape & Reel packaging is standard for automated surface mount assembly processes.

Q: Are both parts suitable for the same operating temperature and voltage applications?

A: Yes. Both 794629-2 and 3-794629-2 operate across the identical temperature range of -40°C to 105°C and carry the same 250V voltage rating. They are fully equivalent for thermal and electrical performance specifications.

Q: What does ROHS3 compliance on 3-794629-2 mean for my application?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, including lead-free material specifications. This is relevant for applications subject to environmental regulations or customer requirements mandating RoHS compliance. The 794629-2 lists RoHS status as "Not applicable," indicating it predates these compliance requirements.

Q: Can I mix 794629-2 and 3-794629-2 in the same assembly?

A: Yes. Both parts are mechanically and electrically identical and can be used interchangeably within the same assembly or system without functional impact.
