TE Connectivity 794066-1 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794066-1 is a shrouded vertical rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This 12-position Mini-Universal MATE-N-LOK series connector features male pins with a 0.163" (4.14mm) pitch and is rated for 600VAC operation across an operating temperature range of -20°C to 85°C. The connector maintains Active product status and is suitable for general-purpose applications requiring reliable solder termination with board lock functionality.

Substitute parts are identified when electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in circuit designs and assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of electrical and mechanical parameters. The following criteria establish functional equivalence:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• 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)
• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 85°C)
• Series designation (Mini-Universal MATE-N-LOK)

Substitute parts must maintain identical mechanical footprint, electrical performance, and environmental ratings to ensure direct replacement capability without circuit redesign or PCB modification.

Parameter Comparison

Engineering Selection Recommendations

Both the 794066-1 and 1-794066-0 maintain Active product status and are manufactured by TE Connectivity within the Mini-Universal MATE-N-LOK series. The parts are electrically and mechanically equivalent for direct substitution in applications requiring 12-position, 0.163" pitch rectangular connector headers with through-hole mounting.

The primary distinction between these parts is the contact finish specification. The 794066-1 features Tin-Lead contact finish, while the 1-794066-0 features Tin contact finish. Both finishes meet the same thickness specification of 150.0µin (3.81µm) and maintain equivalent electrical performance and reliability characteristics.

The 1-794066-0 carries ROHS3 Compliant certification, whereas the 794066-1 RoHS status is listed as Not applicable. For applications subject to RoHS compliance requirements, the 1-794066-0 is the appropriate selection. For applications without RoHS constraints, either part provides equivalent functionality.

Both parts are rated for 600VAC operation across the -20°C to 85°C temperature range and feature UL94 V-0 flammability rating, board lock functionality, and identical mechanical dimensions suitable for general-purpose board-to-cable/wire interconnection.

Frequently Asked Questions (FAQ)

Q: Can the 1-794066-0 directly replace the 794066-1 in existing designs?

A: Yes. The 1-794066-0 is mechanically and electrically equivalent to the 794066-1. Both parts share identical connector type, position count, pitch, mounting configuration, voltage rating, and operating temperature range. Direct substitution is possible without PCB modification or circuit redesign.

Q: What is the difference between the contact finishes specified for these parts?

A: The 794066-1 specifies Tin-Lead contact finish, while the 1-794066-0 specifies Tin contact finish. Both finishes are applied at 150.0µin (3.81µm) thickness and provide equivalent electrical conductivity and mating performance. The Tin finish in the 1-794066-0 aligns with RoHS3 compliance requirements.

Q: Which part should be selected for RoHS-compliant applications?

A: The 1-794066-0 carries ROHS3 Compliant certification and is the appropriate selection for applications subject to RoHS regulatory requirements. The 794066-1 RoHS status is listed as Not applicable.

Q: Are the packaging differences between these parts significant?

A: The 794066-1 packaging is listed as unspecified, while the 1-794066-0 is packaged in Bulk. Packaging differences do not affect electrical or mechanical compatibility. Selection between these parts should be based on application requirements and compliance certifications rather than packaging format.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge for both the 794066-1 and 1-794066-0. Specific current capacity is determined by the gauge of wire terminated to the connector pins. Refer to TE Connectivity documentation for current ratings corresponding to specific wire gauges used in the application.

Q: Are both parts suitable for the full -20°C to 85°C operating temperature range?

A: Yes. Both the 794066-1 and 1-794066-0 are rated for continuous operation across the -20°C to 85°C temperature range. Both parts maintain UL94 V-0 flammability rating and are suitable for general-purpose applications within this thermal envelope.

Q: What does the board lock feature provide?

A: The board lock feature on both connectors provides mechanical retention and strain relief at the PCB interface. This feature prevents accidental disconnection and improves mechanical stability during assembly and field operation.
