Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 794677-2 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Position count (2 positions, 2 rows)
• Row spacing (0.118" / 3.00mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Insulation height (0.290" / 7.37mm)
• Contact shape (Square)

Electrical Compatibility:

• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)
• Material flammability (UL94 V-0)

Termination & Fastening:

• Termination method (Solder)
• Fastening type (Locking Ramp)

The substitute part 3-794677-2 maintains full equivalence across all mechanical and electrical parameters. Differences exist only in product status (Active vs. Obsolete), contact finish composition (Tin vs. Tin-Lead), packaging format (Tray vs. unspecified), and regulatory compliance status (RoHS Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-794677-2 is a direct functional equivalent to the obsolete 794677-2 across all mechanical and electrical parameters critical to connector performance and board integration. Selection of the substitute part is supported by the following factors:

Product Status: The substitute part maintains Active product status, ensuring ongoing availability and manufacturer support, whereas the main part is classified as Obsolete.

Regulatory Compliance: The substitute part 3-794677-2 is RoHS Compliant, meeting current environmental and material restriction requirements. The main part 794677-2 is RoHS non-compliant, which may present procurement and regulatory challenges in applications subject to RoHS directives.

Contact Finish Composition: The substitute part employs pure Tin contact finish, whereas the main part uses Tin-Lead finish. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and are suitable for solder termination applications. The Tin finish of the substitute part aligns with contemporary lead-free manufacturing standards.

Packaging Format: The substitute part is supplied in Tray packaging, providing standardized handling and storage compared to the unspecified packaging of the main part.

Mechanical and Electrical Equivalence: All critical parameters determining connector compatibility remain identical, including position count, row spacing, mounting configuration, shrouding design, operating temperature range, voltage rating, and flammability classification.

Frequently Asked Questions (FAQ)

Q: Can the 3-794677-2 substitute directly replace the 794677-2 in existing designs?

A: Yes. The 3-794677-2 maintains full mechanical and electrical equivalence to the 794677-2 across all parameters governing connector function, board integration, and mating interface. Both parts share identical position count (2), row spacing (0.118" / 3.00mm), mounting type (Through Hole, Right Angle), shrouding configuration (Shrouded - 4 Wall), and electrical ratings (250V, -40°C ~ 105°C).

Q: What is the difference between the Tin-Lead finish of the main part and the Tin finish of the substitute?

A: The main part 794677-2 uses Tin-Lead contact finish, while the substitute 3-794677-2 uses pure Tin finish. Both finishes are applied at identical thickness (100.0µin / 2.54µm) and are compatible with solder termination. The Tin finish of the substitute part reflects current lead-free manufacturing practices and environmental compliance standards.

Q: Why is the substitute part RoHS Compliant while the main part is not?

A: The main part 794677-2 is classified as Obsolete and predates current RoHS compliance requirements. The substitute part 3-794677-2 is an Active product manufactured to current RoHS Compliant standards, which restrict the use of lead and other hazardous substances in electrical and electronic equipment.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts maintain identical voltage rating (250V), operating temperature range (-40°C ~ 105°C), and material flammability classification (UL94 V-0). Current rating varies by wire gauge for both parts.

Q: What is the significance of the packaging difference?

A: The main part 794677-2 has unspecified packaging, while the substitute 3-794677-2 is supplied in Tray packaging. Tray packaging provides standardized handling, storage, and automated assembly compatibility. This difference does not affect connector performance or compatibility.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 794677-2 and 3-794677-2 are manufactured by TE Connectivity AMP Connectors and belong to the Micro MATE-N-LOK series.

Q: Can the 3-794677-2 mate with connectors designed for the 794677-2?

A: Yes. Both parts share identical mating interface specifications, including contact type (Male Pin), position count (2), row spacing (0.118" / 3.00mm), contact shape (Square), and shrouding configuration (Shrouded - 4 Wall). Mating compatibility is fully maintained.

Q: What inventory status should be considered when selecting between these parts?

A: The main part 794677-2 has 726 pieces in stock but is classified as Obsolete with no ongoing production. The substitute part 3-794677-2 has 877 pieces in stock and maintains Active product status, ensuring continued availability and supply chain reliability.
