Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 794630-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Voltage Rating: 250V
• Operating Temperature Range: -40°C to 105°C
• Contact Material: Brass
• Contact Finish Thickness: 100.0µin (2.54µm)

Mechanical Compatibility Parameters:

• Number of Positions: 2
• Number of Rows: 2
• Row Spacing: 0.118" (3.00mm)
• Connector Type: Header
• Mounting Type: Through Hole
• Shrouding Configuration: Shrouded - 4 Wall
• Insulation Material: Polyamide (PA), Nylon
• Insulation Height: 0.364" (9.25mm)
• Contact Shape: Square
• Contact Length - Post: 0.125" (3.18mm)

Functional Parameters:

• Style: Board to Cable/Wire
• Termination: Press-Fit, Solder
• Fastening Type: Locking Ramp
• Number of Positions Loaded: All

The substitute part 3-794630-2 maintains full equivalence across all electrical and mechanical parameters. Differences in packaging format (Tray versus standard packaging), contact finish specification (Tin versus Tin-Lead), and RoHS compliance status do not affect functional interchangeability in applications where the core connector performance requirements are met.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The substitute part 3-794630-2 is functionally equivalent to the main part 794630-2 across all critical electrical and mechanical parameters. Both components are classified as active products with established manufacturing status.

Compliance Considerations:

The 3-794630-2 variant offers RoHS compliance, whereas the 794630-2 is RoHS non-compliant. Applications subject to RoHS regulatory requirements should specify the 3-794630-2 variant. Applications without RoHS mandates may utilize either variant based on procurement availability and inventory status.

Contact Finish Specification:

The main part 794630-2 features Tin-Lead contact finish on both mating and post surfaces. The substitute part 3-794630-2 features Tin contact finish. Both finishes maintain the specified contact finish thickness of 100.0µin (2.54µm) and are functionally equivalent for the stated voltage rating of 250V and operating temperature range of -40°C to 105°C.

Packaging and Inventory:

The 3-794630-2 is supplied in Tray packaging with significantly higher inventory availability (24,936 pieces) compared to the main part (987 pieces). Selection between variants should account for packaging requirements and supply chain lead times.

Certification and Standards:

Both parts maintain UL94 V-0 material flammability rating and identical electrical performance specifications. No additional testing or qualification is required for substitution between these variants in applications where the core connector specifications are met.

Frequently Asked Questions (FAQ)

Q: Can the 3-794630-2 be used as a direct replacement for the 794630-2 in existing designs?

A: Yes. The 3-794630-2 maintains full electrical and mechanical equivalence to the 794630-2 across all critical parameters including voltage rating, operating temperature range, contact configuration, mounting type, and shrouding design. Both components are functionally interchangeable in applications requiring a 2-position Micro MATE-N-LOK header connector with through-hole mounting.

Q: What is the difference between Tin-Lead and Tin contact finishes in this connector series?

A: The main part 794630-2 uses Tin-Lead contact finish, while the substitute 3-794630-2 uses Tin contact finish. Both finishes maintain the specified thickness of 100.0µin (2.54µm) and are suitable for the 250V voltage rating and -40°C to 105°C operating temperature range. The Tin finish in the 3-794630-2 contributes to its RoHS compliance status.

Q: Does the RoHS compliance difference affect connector performance?

A: No. RoHS compliance is a regulatory and material composition specification that does not affect the electrical or mechanical performance of the connector. The RoHS-compliant 3-794630-2 and the RoHS non-compliant 794630-2 deliver identical functional performance. Selection between variants should be based on regulatory requirements applicable to the end application.

Q: Are there packaging considerations when substituting between these parts?

A: Yes. The main part 794630-2 is supplied in standard packaging, while the substitute 3-794630-2 is supplied in Tray packaging. Tray packaging is suitable for automated assembly processes and high-volume production environments. Standard packaging may be preferred for manual assembly or lower-volume applications. Verify packaging compatibility with assembly equipment and processes before substitution.

Q: What is the inventory status of each part?

A: The main part 794630-2 has 987 pieces in stock. The substitute part 3-794630-2 has 24,936 pieces in stock. The significantly higher inventory of the 3-794630-2 may provide supply chain advantages for applications with extended lead time requirements or high-volume procurement needs.

Q: Are both parts suitable for board-to-cable and board-to-wire applications?

A: Yes. Both the 794630-2 and 3-794630-2 are classified as Board to Cable/Wire style connectors with identical mounting and termination specifications. Both support press-fit and solder termination methods and are suitable for the same application categories.

Q: What certifications apply to both connector variants?

A: Both parts maintain UL94 V-0 material flammability rating, indicating compliance with UL94 flammability standards. Both are classified as active products with established manufacturing status. The 3-794630-2 carries additional RoHS compliance certification.
