Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 794680-2 is based on electrical and mechanical parameter equivalence within the Micro MATE-N-LOK connector series. The substitute part 3-794680-2 maintains identical specifications across all critical functional parameters: connector type, number of positions and rows, row spacing, mounting configuration, shrouding design, contact material, insulation material, operating temperature range, voltage rating, and flammability rating.

The primary distinction between the main part and its substitute relates to product status and contact finish specification. The 794680-2 features a Tin-Lead contact finish and carries an obsolete product status. The substitute part 3-794680-2 features a Tin contact finish, maintains active product status, and provides ROHS3 compliance certification. Both parts share identical mechanical interfaces, electrical ratings, and thermal operating parameters, establishing direct functional interchangeability.

Key parameters determining substitution eligibility:

• Connector type and series platform
• Position count and row configuration
• Row spacing and pitch geometry
• Mounting and termination method
• Shrouding and contact geometry
• Operating temperature and voltage ratings
• Material composition and flammability classification

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-794680-2 is the direct equivalent for the obsolete 794680-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 794680-2 carries obsolete status, limiting availability for new production and ongoing supply. The substitute part 3-794680-2 maintains active product status with significantly higher inventory availability (10,926 pieces in stock versus 811 pieces for the obsolete part).

Regulatory Compliance: The substitute part 3-794680-2 carries ROHS3 compliance certification, meeting current regulatory requirements for electronic components in regulated markets. The main part carries "Not applicable" RoHS status, reflecting its obsolete classification.

Contact Finish Specification: The substitute part features a Tin contact finish, replacing the Tin-Lead finish of the main part. Both finishes provide equivalent electrical performance and solder joint reliability within the specified operating parameters.

Mechanical and Electrical Equivalence: All functional parameters remain identical between the main part and substitute, including connector geometry, electrical ratings, thermal operating range, and material specifications. Direct mechanical and electrical interchangeability is established.

For new designs and production applications, the substitute part 3-794680-2 is the appropriate selection. For legacy system repairs requiring exact historical specification matching, the main part 794680-2 remains available in limited inventory.

Frequently Asked Questions (FAQ)

Q: Can the 3-794680-2 substitute directly replace the 794680-2 in existing designs?

A: Yes. The 3-794680-2 provides direct mechanical and electrical interchangeability with the 794680-2. All connector geometry, electrical ratings, operating temperature range, and material specifications are identical. The primary differences are product status (active versus obsolete) and contact finish composition (Tin versus Tin-Lead).

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The Tin contact finish in the substitute part meets current RoHS3 compliance requirements while maintaining equivalent electrical performance and solder joint reliability. Both finishes provide the same mating force characteristics, contact resistance, and durability within the specified operating parameters.

Q: Are there packaging differences between the main part and substitute?

A: Yes. The main part 794680-2 packaging is not specified in available documentation. The substitute part 3-794680-2 is supplied in Tray packaging. This difference affects handling and storage procedures but does not impact electrical or mechanical performance.

Q: Why is the main part classified as obsolete?

A: The 794680-2 is classified as obsolete due to its Tin-Lead contact finish, which does not comply with current RoHS3 regulations. The substitute part 3-794680-2 with Tin finish replaces it in the active product portfolio.

Q: Is the substitute part available in higher quantities?

A: Yes. The substitute part 3-794680-2 has significantly higher inventory availability with 10,926 pieces in stock compared to 811 pieces for the obsolete main part. This availability difference supports production planning and supply chain continuity.

Q: Do both parts share the same base product number?

A: Yes. Both the 794680-2 and 3-794680-2 share the base product number 794680, indicating they are variants within the same product family. The "3-" prefix in the substitute part number indicates the RoHS3-compliant variant.

Q: What applications are these connectors suitable for?

A: Both parts are classified for general-purpose applications. The 2-position, 2-row configuration with 0.118" row spacing, through-hole mounting, and solder termination make these connectors suitable for board-to-cable/wire interconnections in industrial control, instrumentation, and general electronic equipment.

Q: Are the electrical ratings identical between both parts?

A: Yes. Both parts maintain identical voltage rating (250V), operating temperature range (-40°C to 105°C), and current rating specifications (varies by wire gauge). Electrical performance is equivalent across all specified parameters.
