Parts meeting all these criteria are classified as direct substitutes. Variations in packaging format and product status do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 3-794636-8 is a direct functional equivalent to the obsolete 794636-8 part. Both components share identical electrical and mechanical specifications within the Micro MATE-N-LOK series, including connector type, contact configuration, pitch spacing, mounting method, and operating parameters.

Key Differentiation Factors:

Product Status: The 794636-8 is classified as Obsolete, while the 3-794636-8 is Active. For new designs and ongoing procurement, the 3-794636-8 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Status: The 3-794636-8 is ROHS3 Compliant, whereas the 794636-8 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements.

Contact Finish: The 794636-8 features Tin-Lead contact finish on both mating and post surfaces. The 3-794636-8 features Tin contact finish. Both finishes meet the 100.0µin (2.54µm) thickness specification and are compatible with solder termination processes.

Packaging: The 3-794636-8 is supplied in Tape & Reel (TR) format, which is standard for surface mount component procurement and automated assembly operations.

For applications requiring the Rectangular Connector Header Surface Mount 8 position 0.118" (3.00mm) configuration, the 3-794636-8 is the recommended substitute for the obsolete 794636-8.

Frequently Asked Questions (FAQ)

Q: Are the 794636-8 and 3-794636-8 electrically interchangeable?

A: Yes. Both parts are electrically equivalent. They share identical voltage rating (250V), operating temperature range (-40°C ~ 105°C), contact type (Male Pin), number of positions (8), pitch spacing (0.118" / 3.00mm), and row configuration (2 rows).

Q: What is the difference between the contact finishes?

A: The 794636-8 uses Tin-Lead contact finish, while the 3-794636-8 uses Tin contact finish. Both finishes are applied at 100.0µin (2.54µm) thickness and are compatible with solder termination. The Tin finish on the 3-794636-8 reflects RoHS3 compliance requirements.

Q: Can I use the 3-794636-8 in place of the 794636-8 in existing designs?

A: Yes. The 3-794636-8 is a direct substitute for the 794636-8. All mechanical and electrical parameters are identical, including mounting type (Surface Mount), shrouding (Shrouded - 4 Wall), insulation height (0.364" / 9.25mm), and fastening type (Locking Ramp).

Q: Why is the 794636-8 listed as Obsolete?

A: The 794636-8 is an older part number variant. The 3-794636-8 is the current Active equivalent that supersedes it. For new procurement and design work, the 3-794636-8 should be specified.

Q: What is the significance of the packaging difference?

A: The 3-794636-8 is supplied in Tape & Reel (TR) format, which is standard for surface mount component handling and automated assembly. This packaging format is suitable for high-volume production environments and component placement equipment.

Q: Are both parts RoHS compliant?

A: The 794636-8 is RoHS non-compliant. The 3-794636-8 is ROHS3 Compliant. For applications subject to RoHS regulations, the 3-794636-8 is the appropriate selection.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the 794636-8 and 3-794636-8 have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the current rating for these connectors?

A: The current rating varies by wire gauge for both parts. Specific current capacity depends on the wire gauge used in the mated cable/wire configuration.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts have identical mechanical specifications: 0.118" (3.00mm) pitch spacing, 0.118" (3.00mm) row spacing, 0.364" (9.25mm) insulation height, square contact shape, and Shrouded - 4 Wall configuration.

Q: Can these connectors be used in general purpose applications?

A: Yes. Both the 794636-8 and 3-794636-8 are rated for General Purpose applications with operating temperature range of -40°C ~ 105°C and voltage rating of 250V.
