TE Connectivity 794071-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794071-2 is a shrouded vertical rectangular connector header from the Mini-Universal MATE-N-LOK series. This through-hole mounted component features 22 positions arranged in 2 rows with 0.163" (4.14mm) pitch spacing and is designed for board-to-cable/wire applications. The connector employs solder termination with a locking ramp fastening mechanism and gold-plated mating contacts on brass material with polyamide insulation.

The 794071-2 is classified as an active product. Identification of equivalent and substitute parts is necessary to address component availability, procurement lead times, compliance requirements, and manufacturing flexibility while maintaining electrical and mechanical compatibility within the Mini-Universal MATE-N-LOK connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the Mini-Universal MATE-N-LOK connector family is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Number of positions (22)
• Number of rows (2)
• Pitch spacing (0.163" / 4.14mm)
• Row spacing (0.163" / 4.14mm)
• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 105°C)
• Contact type (Male Pin)

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting type (Through Hole)
• Termination method (Solder)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide / Nylon)
• Flammability rating (UL94 V-0)

Contact Material Parameters:

• Contact material (Brass)
• Contact shape (Circular)
• Mating contact finish (Gold)
• Mating contact finish thickness (30.0µin / 0.76µm)
• Post contact finish thickness (150.0µin / 3.81µm)

The substitute part 1-794071-1 maintains full equivalence across all critical electrical and mechanical parameters. Differences exist only in packaging configuration and regulatory compliance status, which do not affect functional interchangeability in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

794071-2 Selection Criteria:

The 794071-2 is appropriate for applications where RoHS non-compliant components are acceptable or required by specification. This part number maintains the original tin-lead post contact finish specification and is suitable for legacy systems or applications with established qualification histories using this exact part number.

1-794071-1 Selection Criteria:

The 1-794071-1 is the preferred substitute for new designs and applications requiring ROHS3 compliance. This part maintains full electrical and mechanical equivalence to the 794071-2 while providing enhanced regulatory compliance status. The post contact finish specification differs only in the elimination of lead content (Tin vs. Tin-Lead), which does not affect functional performance or mating compatibility. Both parts are active products with current manufacturing status and adequate inventory availability.

Interchangeability Statement:

The 794071-2 and 1-794071-1 are functionally interchangeable in all Mini-Universal MATE-N-LOK connector applications. Selection between these parts should be based on regulatory compliance requirements, procurement availability, and project-specific material restrictions rather than electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Are the 794071-2 and 1-794071-1 electrically identical?

A: Yes. Both parts maintain identical voltage ratings (600VAC), operating temperature ranges (-20°C ~ 105°C), contact materials (brass with gold mating finish), and all electrical specifications. The parts are electrically interchangeable.

Q: What is the difference between the post contact finishes (Tin-Lead vs. Tin)?

A: The 794071-2 uses tin-lead plating on the solder posts, while the 1-794071-1 uses tin-only plating. Both finishes meet the 150.0µin (3.81µm) thickness specification and provide equivalent solderability and mechanical performance. The tin-only finish on the 1-794071-1 reflects ROHS3 compliance requirements.

Q: Can I substitute 1-794071-1 for 794071-2 in existing designs?

A: Yes. The 1-794071-1 is a direct functional substitute for the 794071-2. All mechanical dimensions, electrical ratings, and mating characteristics are identical. The substitution does not require design changes or re-qualification of the connector interface.

Q: What is the significance of the packaging difference (unspecified vs. Bulk)?

A: Packaging designation indicates the form in which the component is supplied. The 794071-2 packaging is not specified in the available data, while the 1-794071-1 is supplied in bulk packaging. This difference affects procurement and handling procedures but does not impact the component's electrical or mechanical performance.

Q: Why does the RoHS status differ between these parts?

A: The 794071-2 is classified as RoHS non-compliant due to the tin-lead post contact finish. The 1-794071-1 achieves ROHS3 compliance through the use of tin-only post contact finish, eliminating lead content. Both parts are manufactured by TE Connectivity and represent different compliance generations of the same connector design.

Q: Are both parts currently available for procurement?

A: Yes. Both the 794071-2 (1043 pcs in stock) and 1-794071-1 (1031 pcs in stock) are active products with current inventory availability. Selection should be based on application requirements and compliance specifications rather than availability constraints.

Q: What is the Mini-Universal MATE-N-LOK series?

A: The Mini-Universal MATE-N-LOK is a TE Connectivity connector series designed for board-to-cable/wire applications. The series is characterized by 0.163" (4.14mm) pitch spacing, shrouded 4-wall construction, locking ramp fastening, and through-hole solder termination. Both the 794071-2 and 1-794071-1 are members of this series.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for operating temperatures from -20°C to 105°C. Applications requiring operation outside this range require alternative connector designs.

Q: What is the board lock feature?

A: The board lock feature is a mechanical design element that provides positive retention of the connector to the printed circuit board during mating and unmating cycles, preventing accidental disconnection.
