TE Connectivity 4-794634-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 4-794634-6 is a surface mount rectangular connector header from the Micro MATE-N-LOK series. This 16-position, 2-row connector operates at 250V with an operating temperature range of -40°C to 105°C. The part features a 0.118" (3.00mm) pitch, shrouded 4-wall design, and solder termination with locking ramp fastening. The connector is actively manufactured and RoHS compliant with UL94 V-0 flammability rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design alternatives where specific contact finish or feature requirements differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers within the Micro MATE-N-LOK series is determined by strict equivalence in the following critical parameters:

Mechanical Compatibility Parameters:

• Number of positions: 16
• Number of rows: 2
• Pitch - mating: 0.118" (3.00mm)
• Row spacing - mating: 0.118" (3.00mm)
• Mounting type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Locking Ramp

Electrical Compatibility Parameters:

• Voltage rating: 250V
• Operating temperature range: -40°C ~ 105°C
• Contact material: Brass
• Contact shape: Square

Regulatory & Environmental Parameters:

• Material flammability rating: UL94 V-0
• RoHS compliance: Required
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 4-794636-6 maintains full equivalence across all mechanical, electrical, and regulatory parameters. The primary difference is the contact finish specification on the mating surface: the main part features gold plating at 15.0µin (0.38µm), while the substitute features tin plating at 100.0µin (2.54µm). Additionally, the substitute includes solder retention as a feature, whereas the main part includes board lock and pick-and-place features. Both parts are actively manufactured and in stock.

Parameter Comparison

Engineering Selection Recommendations

Both the 4-794634-6 and 4-794636-6 are actively manufactured products with full RoHS compliance and UL94 V-0 flammability certification. Selection between these parts is determined by contact finish requirements and application-specific environmental conditions.

4-794634-6 Selection Criteria:

• Applications requiring gold-plated mating contacts for enhanced corrosion resistance
• Environments with higher humidity or corrosive atmospheres
• Designs incorporating board lock and pick-and-place assembly features
• Systems where contact reliability in harsh conditions is prioritized

4-794636-6 Selection Criteria:

• Applications where tin-plated mating contacts are acceptable
• Standard industrial and general-purpose applications
• Designs requiring solder retention feature for improved solder joint integrity
• Cost-sensitive applications where tin plating provides adequate performance

Both parts maintain identical mechanical footprints, electrical ratings, and regulatory compliance. The choice between gold and tin contact finishes depends on application environment, assembly process requirements, and cost considerations. Both parts are available in Tape & Reel packaging with unlimited moisture sensitivity level (MSL 1), suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Are the 4-794634-6 and 4-794636-6 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 16 positions, 2-row configuration, 0.118" (3.00mm) pitch, shrouded 4-wall design, and surface mount termination. They occupy the same PCB footprint and mate with identical cable connectors.

Q: What is the functional difference between gold and tin contact finishes?

A: Gold plating provides superior corrosion resistance and is specified for applications exposed to moisture, salt spray, or corrosive atmospheres. Tin plating is suitable for standard industrial environments and general-purpose applications. Both finishes maintain electrical conductivity and contact reliability within the specified operating temperature range of -40°C to 105°C.

Q: Can I use 4-794636-6 as a direct replacement for 4-794634-6 in an existing design?

A: Direct replacement is possible from a mechanical and electrical standpoint. However, the contact finish difference (gold versus tin) and feature differences (board lock/pick-and-place versus solder retention) should be evaluated against application requirements. If the original design specifies gold plating for environmental protection, substitution with tin plating may not be appropriate.

Q: Are both parts RoHS compliant?

A: Yes. Both 4-794634-6 and 4-794636-6 are RoHS compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and consumer applications.

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

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard storage and handling conditions are acceptable without special desiccant packaging or baking requirements.

Q: What is the voltage and current rating for these connectors?

A: Both connectors are rated for 250V. Current rating varies by wire gauge and is determined by the specific wire or cable used in the application, not by the connector itself.

Q: Are these connectors available in other configurations?

A: The information provided covers only the 16-position, 2-row surface mount variants. The Micro MATE-N-LOK series may include other position counts and configurations; consult the manufacturer's full product line for alternative options.

Q: What is the operating temperature range?

A: Both connectors operate across -40°C to 105°C, suitable for industrial, automotive, and general-purpose applications across standard and extended temperature environments.
