• Number of rows: 2
• Row spacing: 0.118" (3.00mm)
• Contact type: Male Pin
• Voltage rating: 250V
• Operating temperature range: -40°C ~ 105°C

Mechanical Parameters:

• Mounting type: Through Hole, Right Angle
• Shrouding configuration: Shrouded - 4 Wall
• Termination method: Solder
• Fastening type: Locking Ramp
• Insulation height: 0.290" (7.37mm)
• Contact shape: Square
• Insulation material: Polyamide (PA), Nylon
• Board Lock feature: Present

Material & Compliance Parameters:

• Contact material: Brass
• Flammability rating: UL94 V-0
• Series: Micro MATE-N-LOK

The substitute part 3-794618-8 meets all these criteria and is classified as an active product with improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The part 3-794618-8 is the direct active equivalent for the obsolete 794618-8. Selection of the substitute is based on the following engineering criteria:

Product Status: The original 794618-8 is classified as obsolete. The substitute 3-794618-8 maintains active product status with TE Connectivity, ensuring continued availability and manufacturing support.

Electrical & Mechanical Equivalence: All critical electrical parameters (pitch, position count, voltage rating, temperature range) and mechanical parameters (mounting type, shrouding, termination method, fastening type) are identical between the original and substitute parts. This ensures direct functional interchangeability in existing circuit board designs and cable assemblies.

Compliance Improvement: The substitute part 3-794618-8 is ROHS3 compliant, whereas the original 794618-8 is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic components in most markets.

Contact Finish Specification: The original part specifies Tin-Lead contact finish, while the substitute specifies Tin contact finish. Both finishes provide equivalent electrical and mechanical performance for solder termination applications and are functionally interchangeable.

Packaging & Inventory: The substitute is supplied in standard tray packaging with significantly higher inventory availability (14,200 pieces versus 911 pieces), supporting both new production and field service requirements.

For new designs and production applications, the 3-794618-8 is the recommended selection. For legacy system maintenance where the original 794618-8 is no longer available, the 3-794618-8 provides direct functional replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 3-794618-8 be used as a direct replacement for the 794618-8 in existing designs?

A: Yes. The 3-794618-8 is a direct functional equivalent. All electrical parameters (pitch, position count, voltage rating, operating temperature), mechanical parameters (mounting type, shrouding, termination method), and physical dimensions are identical. No circuit board layout or cable assembly modifications are required.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: Both finishes provide equivalent electrical conductivity and mechanical performance for solder termination applications. Tin is a lead-free alternative that meets current RoHS compliance requirements. The functional performance in solder joint formation and electrical connection is equivalent.

Q: Why is the substitute part classified as ROHS3 compliant while the original is not?

A: The original 794618-8 was manufactured with Tin-Lead contact finish, which contains lead and does not meet RoHS compliance. The substitute 3-794618-8 uses Tin contact finish (lead-free), meeting ROHS3 compliance standards. This reflects the evolution of manufacturing standards and regulatory requirements.

Q: Are there any packaging differences between the two parts?

A: The original 794618-8 packaging is not specified in the technical data. The substitute 3-794618-8 is supplied in tray packaging, which is standard for high-volume production and field service applications.

Q: What is the inventory status of each part?

A: The original 794618-8 has 911 pieces in stock and is classified as obsolete. The substitute 3-794618-8 has 14,200 pieces in stock and is classified as active. For new production, the substitute offers superior supply chain continuity.

Q: Are the electrical specifications identical between the two parts?

A: Yes. Both parts operate at 250V, support the same current rating (varies by wire gauge), operate across the same temperature range (-40°C ~ 105°C), and maintain identical pitch (3.00mm), position count (8), and row configuration (2 rows).

Q: Can the 3-794618-8 be used in applications where the original 794618-8 was specified?

A: Yes. The 3-794618-8 meets all electrical, mechanical, and dimensional requirements of the original specification. It is suitable for general-purpose board-to-cable/wire applications with identical performance characteristics.

Q: What is the significance of the Board Lock feature?

A: The Board Lock feature is present on both parts and provides mechanical retention of the connector to the circuit board during mating and unmating cycles. This feature is identical on both the original and substitute parts.

Q: Is the Moisture Sensitivity Level (MSL) the same for both parts?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
