TE Connectivity 794066-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794066-2 is a shrouded vertical rectangular connector header from the Mini-Universal MATE-N-LOK series. This through-hole mounted component features 12 positions arranged in 2 rows with 0.163" (4.14mm) pitch spacing, designed for board-to-cable/wire applications. The connector utilizes male pin contacts with gold-plated mating surfaces and tin-lead plated posts for solder termination.

The 794066-2 maintains active product status with 1052 units in current inventory. Substitute part identification becomes necessary when packaging requirements differ, when specific compliance certifications are required, or when alternative contact finish specifications are needed for particular application environments.

Parameter Comparison

Engineering Selection Recommendations

794066-2 Selection Criteria:

• Standard packaging configuration required
• Applications where RoHS compliance status is not a constraint
• Tin-Lead post finish specification required for legacy system compatibility

1-794066-1 Selection Criteria:

• Bulk packaging configuration acceptable
• ROHS3 compliance certification required
• Tin post finish specification acceptable
• Higher inventory availability for volume requirements

Both parts maintain identical electrical performance, mechanical dimensions, and thermal operating characteristics. The primary differentiators are packaging format, post contact finish composition, and regulatory compliance certification. Selection between these parts depends on procurement specifications, regulatory requirements, and packaging logistics rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Are the 794066-2 and 1-794066-1 electrically interchangeable?

A: Yes. Both connectors operate at 600VAC, support the same current rating based on wire gauge, and maintain identical contact materials, finishes, and dimensions. The electrical performance is equivalent across all specified parameters.

Q: What is the difference between Tin-Lead and Tin post finishes?

A: The 794066-2 features Tin-Lead plated posts while the 1-794066-1 features Tin plated posts. Both finishes provide equivalent solder joint reliability and mechanical strength at the specified 150.0µin (3.81µm) thickness. Selection depends on application-specific material restrictions or legacy system requirements.

Q: Does the packaging difference affect connector performance?

A: No. Bulk packaging (1-794066-1) and standard packaging (794066-2) contain identical connectors. Packaging differences affect only handling, storage, and procurement logistics, not electrical or mechanical function.

Q: What does ROHS3 compliance mean for the 1-794066-1?

A: ROHS3 compliance indicates the 1-794066-1 meets Restriction of Hazardous Substances Directive requirements. The 794066-2 lists RoHS status as "Not applicable." This distinction is relevant for applications subject to European Union environmental regulations or customer-mandated compliance requirements.

Q: Can I use these connectors in the same PCB design?

A: Yes. Both connectors share identical mounting specifications (Through Hole), pitch (0.163"), row spacing (0.163"), insulation height (0.531"), and all mechanical dimensions. PCB footprints and assembly processes are identical.

Q: What is the operating temperature range for both parts?

A: Both the 794066-2 and 1-794066-1 operate across -20°C to 105°C. This range applies to all electrical and mechanical specifications.

Q: Are there any inventory considerations when selecting between these parts?

A: The 1-794066-1 maintains higher inventory availability (2744 Pcs) compared to the 794066-2 (1052 Pcs). For volume production or time-sensitive procurement, the 1-794066-1 may offer supply chain advantages.
