Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across critical electrical and mechanical parameters. The following parameters establish substitution validity for the TE Connectivity 794105-1:

Electrical Parameters:

• Contact type (Male Pin)
• Number of positions (18)
• Row configuration (2 rows)
• Pitch spacing (0.163" / 4.14mm mating pitch and row spacing)
• Voltage rating (600VAC minimum)
• Operating temperature range (-20°C ~ 85°C minimum)

Mechanical Parameters:

• Connector type (Header)
• Mounting style (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Locking Ramp)
• Termination method (Solder)
• Contact material (Brass)
• Insulation material (Polyamide/Nylon)
• Insulation height (0.386" / 9.80mm)
• Contact post length (0.145" / 3.68mm)
• Contact shape (Circular)

Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

Substitute parts maintain all specified electrical and mechanical parameters while potentially differing in contact finish composition and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-794105-0 is a direct functional substitute for the 794105-1 rectangular connector header. Both parts are manufactured by TE Connectivity within the Mini-Universal MATE-N-LOK series and maintain identical electrical and mechanical specifications across all critical interface parameters.

Key Differences:

The primary distinction between these parts is the contact finish composition. The 794105-1 features Tin-Lead plating on both mating and post contacts, while the 1-794105-0 uses pure Tin plating. Both finishes maintain the same thickness specification of 150.0µin (3.81µm) and provide equivalent electrical performance and contact reliability.

Compliance Consideration:

The 1-794105-0 is ROHS3 compliant, whereas the 794105-1 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations. The 1-794105-0 is the appropriate selection for designs requiring RoHS compliance.

Inventory Availability:

The 1-794105-0 has greater inventory availability with 2160 pieces in stock compared to 819 pieces for the 794105-1, providing supply chain advantages for high-volume production requirements.

Both parts are active products with identical product status, operating temperature ranges (-20°C ~ 85°C), voltage ratings (600VAC), and material flammability certifications (UL94 V-0).

Frequently Asked Questions (FAQ)

Q: Can the 1-794105-0 be used as a direct replacement for the 794105-1 in existing designs?

A: Yes. The 1-794105-0 maintains all critical electrical and mechanical parameters required for functional equivalence. The connector type, position count, pitch spacing, mounting configuration, and termination method are identical. Both parts are compatible with the same mating connectors and circuit board layouts.

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

A: The 794105-1 uses Tin-Lead plating while the 1-794105-0 uses pure Tin plating. Both finishes provide equivalent electrical conductivity and contact reliability at the specified thickness of 150.0µin (3.81µm). The Tin finish in the 1-794105-0 supports RoHS3 compliance requirements.

Q: Which part should be selected for new designs?

A: For new designs, the 1-794105-0 is the recommended selection based on its ROHS3 compliance status and superior inventory availability. The part maintains all functional equivalence to the 794105-1 while meeting modern regulatory requirements.

Q: Are there any temperature or voltage limitations when substituting these parts?

A: No. Both parts operate across the identical temperature range of -20°C ~ 85°C and maintain the same 600VAC voltage rating. Thermal and electrical performance characteristics are equivalent.

Q: What is the row spacing configuration for these connectors?

A: Both the 794105-1 and 1-794105-0 feature 18 positions arranged in 2 rows with 0.163" (4.14mm) spacing between rows. This configuration is maintained across both parts for mechanical compatibility.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts have a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard component storage practices are sufficient.

Q: What fastening mechanism is used with these connectors?

A: Both parts utilize a locking ramp fastening type, which provides secure mating and prevents accidental disconnection. This feature is consistent across both the 794105-1 and 1-794105-0.

Q: Are the insulation materials identical between these parts?

A: Yes. Both parts use Polyamide (PA) Nylon insulation material with white coloring and an insulation height of 0.386" (9.80mm). The mechanical insulation properties are equivalent.

Q: What is the contact post length for these connectors?

A: Both the 794105-1 and 1-794105-0 feature a contact post length of 0.145" (3.68mm), ensuring consistent solder joint depth and board-level integration.
