TE Connectivity 794070-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794070-2 is a shrouded rectangular connector header from the Mini-Universal MATE-N-LOK series, designed for through-hole board-to-cable/wire applications. This 20-position, 2-row header connector features a 0.163" (4.14mm) pitch and is rated for 600VAC operation across an extended temperature range of -20°C to 105°C. The connector employs solder termination with a locking ramp fastening mechanism and board lock feature for secure mounting.

The part is currently active in production with 767 units in stock. Identifying equivalent and substitute parts is necessary to support design flexibility, manage supply chain continuity, and accommodate varying compliance requirements across different manufacturing environments and regulatory jurisdictions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 794070-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a part to function as a direct substitute:

Mandatory Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (20)
• Number of rows (2)
• Pitch - mating (0.163" / 4.14mm)
• Row spacing - mating (0.163" / 4.14mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 105°C)
• Material flammability rating (UL94 V-0)
• Series designation (Mini-Universal MATE-N-LOK)

Variations in contact finish specifications, compliance certifications, or inventory status do not affect functional interchangeability when all mandatory parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-794070-1 is a direct functional equivalent to the 794070-2 across all critical electrical and mechanical parameters. Both connectors share identical specifications for connector type, contact configuration, pitch, mounting method, voltage rating, and operating temperature range.

Compliance Considerations:

The primary distinction between these parts relates to regulatory compliance status. The 794070-2 is RoHS non-compliant, while the 1-794070-1 is ROHS3 compliant. This difference reflects the post-solder finish specification: the 794070-2 uses Tin-Lead plating on the post, whereas the 1-794070-1 uses Tin plating. For applications subject to RoHS3 regulations or requiring lead-free manufacturing processes, the 1-794070-1 is the appropriate selection.

Inventory and Availability:

The 1-794070-1 maintains higher inventory availability with 1802 units in stock compared to 767 units for the 794070-2, supporting supply chain continuity for high-volume production requirements.

Both parts are active products from TE Connectivity AMP Connectors and maintain identical mechanical and electrical performance characteristics within the Mini-Universal MATE-N-LOK series.

Frequently Asked Questions (FAQ)

Q: Can the 1-794070-1 be used as a direct replacement for the 794070-2 in existing designs?

A: Yes. The 1-794070-1 is functionally equivalent to the 794070-2 across all critical electrical and mechanical parameters, including connector type, contact configuration, pitch, mounting method, voltage rating, and operating temperature range. Both parts are interchangeable from a design and assembly perspective.

Q: What is the difference between the 794070-2 and 1-794070-1?

A: The primary differences are the post-solder contact finish and RoHS compliance status. The 794070-2 features Tin-Lead plating and is RoHS non-compliant. The 1-794070-1 features Tin plating and is ROHS3 compliant. The mating contact finish (Gold) is identical on both parts.

Q: Which part should be selected for RoHS3-regulated applications?

A: The 1-794070-1 is ROHS3 compliant and is the appropriate selection for applications subject to RoHS3 regulations or requiring lead-free manufacturing processes.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical voltage ratings (600VAC), operating temperature ranges (-20°C to 105°C), and current handling capabilities. Electrical performance is equivalent.

Q: Do these connectors require specific mating components?

A: Both the 794070-2 and 1-794070-1 are header connectors designed for board-to-cable/wire applications within the Mini-Universal MATE-N-LOK series. They require compatible receptacle connectors from the same series for proper mating.

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

A: The Board Lock feature provides mechanical retention of the connector to the printed circuit board during assembly and operation, preventing accidental disconnection or movement.

Q: Are these parts suitable for high-temperature applications?

A: Both connectors are rated for operation across -20°C to 105°C. Applications requiring operation outside this temperature range require alternative connector selections.
