• Identical pitch spacing (0.118" / 3.00mm) for both mating and row spacing
• Identical voltage rating (250V)
• Identical operating temperature range (-40°C ~ 105°C)
• Identical contact type (Male Pin)
• Identical series designation (Micro MATE-N-LOK)

Mechanical Compatibility Parameters:

• Identical mounting type (Through Hole, Right Angle)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Identical termination method (Solder)
• Identical fastening type (Locking Ramp)
• Identical insulation height (0.290" / 7.37mm)
• Identical contact shape (Square)
• Identical insulation material (Polyamide PA, Nylon)
• Identical insulation color (Black)

Distinguishing Factors:

• Packaging format (Bulk vs. Tray)
• Contact finish on post termination (Tin-Lead vs. Tin)
• RoHS compliance status (Non-compliant vs. ROHS3 Compliant)
• REACH status (REACH Affected vs. Vendor Undefined)

Parameter Comparison

Engineering Selection Recommendations

Selection Criteria Based on Product Status and Compliance:

The 794620-8 and 3-794620-8 are functionally equivalent rectangular connectors within the Micro MATE-N-LOK series. Both parts maintain Active product status and share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch spacing, voltage rating, and operating temperature range.

For RoHS3 Compliant Applications: Select part number 3-794620-8. This variant carries ROHS3 Compliant certification and is suitable for applications subject to RoHS Directive 2011/65/EU requirements. The contact finish on the post termination is Tin, which aligns with lead-free soldering processes.

For Non-Compliant or Legacy Applications: Select part number 794620-8. This variant carries RoHS non-compliant status and features Tin-Lead contact finish on the post termination, suitable for applications not subject to RoHS restrictions or requiring traditional lead-based solder compatibility.

For Packaging Considerations: The 794620-8 is supplied in bulk packaging, while 3-794620-8 is supplied in tray packaging. Tray packaging (3-794620-8) provides improved handling, storage, and automated assembly compatibility. Bulk packaging (794620-8) may be preferred for manual assembly or specific inventory management protocols.

Inventory Availability: Part 3-794620-8 maintains higher inventory levels (3527 Pcs) compared to 794620-8 (778 Pcs), making it the preferred selection for applications with extended lead time requirements or high-volume procurement needs.

Frequently Asked Questions (FAQ)

Q: Are 794620-8 and 3-794620-8 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including mounting type (Through Hole, Right Angle), shrouding configuration (Shrouded - 4 Wall), insulation height (0.290" / 7.37mm), and contact geometry. They are directly interchangeable in PCB designs without layout modifications.

Q: Are 794620-8 and 3-794620-8 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including voltage rating (250V), operating temperature range (-40°C ~ 105°C), contact type (Male Pin), and pitch spacing (0.118" / 3.00mm). They perform identically in electrical applications.

Q: What is the difference in contact finish between these parts?

A: The 794620-8 features Tin-Lead contact finish on the post termination, while 3-794620-8 features Tin contact finish. Both maintain identical Gold contact finish on the mating surface (30.0µin / 0.76µm thickness). The post finish difference reflects RoHS compliance status and soldering process compatibility.

Q: Which part should I select for RoHS-regulated applications?

A: Select 3-794620-8, which carries ROHS3 Compliant certification. This part is suitable for applications subject to RoHS Directive 2011/65/EU and equivalent regional regulations.

Q: Does packaging format affect connector performance?

A: No. The bulk packaging of 794620-8 and tray packaging of 3-794620-8 do not affect electrical or mechanical performance. Packaging selection depends on assembly process requirements, inventory management, and handling protocols.

Q: Can I use 3-794620-8 as a direct replacement for 794620-8 in existing designs?
