Substitute Part Grouping Explanation

Substitute parts for the 1-794679-0 are identified based on electrical and mechanical parameter equivalence within the Micro MATE-N-LOK series. The following parameters establish substitution validity:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (10)
• Number of rows (2)
• Pitch spacing (0.118" / 3.00mm)
• Row spacing (0.118" / 3.00mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding style (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Locking Ramp)
• Operating temperature range (-40°C ~ 105°C)
• Voltage rating (250V)

Parts matching all critical parameters are classified as direct electrical and mechanical equivalents. Variations in packaging format, product status, or compliance certifications do not affect functional interchangeability in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The 4-794679-0 is the direct substitute for the obsolete 1-794679-0. Both parts are manufactured by TE Connectivity AMP Connectors within the Micro MATE-N-LOK series and share identical electrical and mechanical specifications.

Product Status Consideration: The 1-794679-0 is classified as obsolete, while the 4-794679-0 maintains active product status with significantly higher inventory availability (6589 pieces versus 773 pieces). Selection of the active part ensures long-term supply chain continuity.

Compliance Difference: The 4-794679-0 carries ROHS3 compliance certification, whereas the 1-794679-0 is marked as not applicable. For applications subject to RoHS regulatory requirements, the 4-794679-0 provides documented compliance.

Contact Finish Variation: The 1-794679-0 specifies Tin-Lead post finish, while the 4-794679-0 specifies Tin post finish. Both maintain the same contact finish thickness (100.0µin / 2.54µm) and do not affect electrical performance or mechanical interchangeability in standard applications.

Packaging Format: The 4-794679-0 is supplied in tray packaging, which may differ from the original part's packaging specification. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 4-794679-0 be used as a direct replacement for the 1-794679-0 in existing designs?

A: Yes. The 4-794679-0 is electrically and mechanically equivalent to the 1-794679-0. Both connectors share identical pitch spacing (0.118" / 3.00mm), position count (10 positions in 2 rows), mounting configuration (through-hole right-angle), and operating specifications (-40°C ~ 105°C, 250V rating). The parts are interchangeable at the circuit board level.

Q: What is the significance of the product status difference between these parts?

A: The 1-794679-0 is obsolete, indicating TE Connectivity has discontinued active production and support. The 4-794679-0 is active, meaning it remains in current production with ongoing availability. For new designs or long-term supply requirements, the active part is the appropriate selection.

Q: Does the Tin-Lead versus Tin post finish difference affect compatibility?

A: No. Both finishes maintain the same contact finish thickness (100.0µin / 2.54µm) and provide equivalent electrical conductivity and solder joint reliability. The post finish does not affect mating performance or mechanical interchangeability.

Q: Are there any compliance or regulatory differences between these parts?

A: The 4-794679-0 carries ROHS3 compliance certification, while the 1-794679-0 is marked as not applicable. If your application or market requires RoHS compliance documentation, the 4-794679-0 provides certified compliance. Both parts maintain UL94 V-0 flammability rating and identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What packaging format should I expect for the 4-794679-0?

A: The 4-794679-0 is supplied in tray packaging. Confirm this packaging format aligns with your assembly and procurement workflows before ordering.

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts operate at 250V rating, support current ratings that vary by wire gauge, and function across the identical temperature range (-40°C ~ 105°C). The shrouded 4-wall construction, locking ramp fastening, and board lock features are identical on both parts.

Q: What is the inventory status for each part?

A: The 1-794679-0 has 773 pieces in stock (obsolete status). The 4-794679-0 has 6589 pieces in stock (active status). The substitute part offers substantially higher availability for immediate procurement needs.
