Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 794069-1 is based on strict electrical and mechanical parameter matching within the Mini-Universal MATE-N-LOK series. The substitute part must satisfy the following criteria:

Critical Matching Parameters:

• Connector type: Header
• Number of positions: 18
• Number of rows: 2
• Pitch - mating: 0.163" (4.14mm)
• Row spacing - mating: 0.163" (4.14mm)
• Contact type: Male Pin
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Voltage rating: 600VAC
• Operating temperature range: -20°C ~ 85°C
• Material flammability rating: UL94 V-0
• Insulation material: Polyamide (PA), Nylon
• Contact material: Brass
• Termination: Solder
• Fastening type: Locking Ramp

The substitute part 1-794069-0 maintains all critical electrical and mechanical parameters. The primary difference is the contact finish specification on mating and post surfaces, which changes from Tin-Lead to Tin, and the product status transitions from obsolete to active with improved RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-794069-0 is the direct active equivalent for the obsolete 794069-1. Selection of this substitute is based on the following engineering factors:

Product Status: The 794069-1 is classified as obsolete, while the 1-794069-0 maintains active product status with established supply chain availability (3437 pieces in stock versus 850 pieces for the obsolete variant).

Regulatory Compliance: The 1-794069-0 achieves RoHS compliance, whereas the 794069-1 is RoHS non-compliant. This distinction is significant for applications subject to RoHS directives and environmental regulations.

Contact Finish Specification: The substitute part specifies Tin contact finish on both mating and post surfaces, replacing the Tin-Lead finish of the original part. Both finishes maintain the identical 150.0µin (3.81µm) thickness specification and are compatible for solder termination applications.

Electrical and Mechanical Equivalence: All critical parameters remain identical, including the 18-position configuration, 0.163" (4.14mm) pitch, 600VAC voltage rating, -20°C to 85°C operating temperature range, UL94 V-0 flammability rating, and through-hole mounting specification.

Base Product Number Alignment: Both parts share the base product number 794069, confirming their functional equivalence within the Mini-Universal MATE-N-LOK series.

Frequently Asked Questions (FAQ)

Q: Can the 1-794069-0 be used as a direct replacement for the 794069-1 in existing designs?

A: Yes. The 1-794069-0 maintains identical electrical and mechanical specifications for all critical parameters, including connector type, position count, pitch, voltage rating, operating temperature range, and mounting configuration. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the Tin-Lead finish on the 794069-1 and the Tin finish on the 1-794069-0?

A: Both finishes provide equivalent contact performance and solder compatibility at the specified 150.0µin (3.81µm) thickness. The Tin finish on the 1-794069-0 reflects modern manufacturing standards and supports RoHS compliance requirements.

Q: Why is the 794069-1 classified as obsolete?

A: The 794069-1 is obsolete due to its RoHS non-compliant status and the availability of the active equivalent 1-794069-0, which provides improved regulatory compliance and established supply chain support.

Q: Are there packaging differences between the two parts?

A: The 794069-1 packaging specification is not provided in the technical data. The 1-794069-0 is supplied in bulk packaging. Confirm packaging requirements with the supplier for specific application needs.

Q: What is the current availability of these parts?

A: The obsolete 794069-1 has 850 pieces in stock. The active substitute 1-794069-0 has 3437 pieces in stock, providing superior supply chain availability.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 794069-1 and 1-794069-0 operate across the identical temperature range of -20°C to 85°C.

Q: Does the 1-794069-0 meet the same flammability standards as the 794069-1?

A: Yes. Both parts maintain the UL94 V-0 material flammability rating.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
