TE Connectivity 794626-4 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794626-4 is a surface mount, right-angle rectangular connector header in the Micro MATE-N-LOK series. This connector is designed for board-to-cable/wire applications with 4 positions arranged in 2 rows at 0.118" (3.00mm) pitch. The part features shrouded 4-wall construction with gold-plated mating contacts and tin-lead plated posts, operating across -40°C to 105°C with a 250V rating.

The 794626-4 carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 794626-4 rectangular connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Number of rows (2)
• Pitch spacing (0.118" / 3.00mm mating pitch and row spacing)
• Voltage rating (250V minimum)
• Operating temperature range (-40°C ~ 105°C)

Mechanical Compatibility:

• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Series designation (Micro MATE-N-LOK)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

Contact Specifications:

• Contact material (Brass)
• Contact shape (Square)
• Mating contact finish (Gold)
• Post contact finish (Tin or Tin-Lead)
• Contact finish thickness specifications

Substitute parts must maintain identical electrical and mechanical characteristics across all listed parameters to ensure direct interchangeability without design modification or functional degradation.

Parameter Comparison

Engineering Selection Recommendations

The 3-794626-4 is a direct functional equivalent to the obsolete 794626-4 rectangular connector. Both parts share identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch spacing, mounting orientation, shrouding, and operating ratings.

Key Advantages of 3-794626-4:

The substitute part carries an active product status, ensuring ongoing availability and supply chain support. The 3-794626-4 is ROHS3 compliant, meeting current regulatory requirements for new designs and production environments. The part is supplied in standard Tape & Reel packaging, facilitating automated assembly processes.

Contact Finish Consideration:

The primary specification difference is the post contact finish. The original 794626-4 features tin-lead plating, while the 3-794626-4 uses tin plating. Both finishes maintain the specified 100.0µin (2.54µm) thickness and provide equivalent solderability and electrical performance for board-level termination applications.

Compliance Status:

The 794626-4 is RoHS non-compliant due to its tin-lead post finish. The 3-794626-4 achieves ROHS3 compliance through its tin post finish, making it suitable for applications subject to RoHS regulations and modern manufacturing standards.

The 3-794626-4 is a direct replacement for the 794626-4 without requiring design modifications, PCB layout changes, or functional re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the 3-794626-4 be used as a direct replacement for the 794626-4 in existing designs?

A: Yes. The 3-794626-4 is electrically and mechanically identical to the 794626-4 across all critical parameters. Both connectors feature the same 4-position, 2-row configuration with 0.118" (3.00mm) pitch, surface mount right-angle mounting, shrouded 4-wall construction, and 250V operating rating. No design modifications are required.

Q: What is the difference between the tin-lead and tin post finishes?

A: Both finishes provide equivalent solderability and electrical performance for solder termination applications. The tin-lead finish on the 794626-4 is RoHS non-compliant, while the tin finish on the 3-794626-4 is ROHS3 compliant. The tin finish is the current standard for new connector production.

Q: Why is the 794626-4 listed as obsolete?

A: The 794626-4 has been superseded by the 3-794626-4 in the manufacturer's product line. The 3-794626-4 offers improved regulatory compliance and active production support. The 794626-4 remains available from existing inventory but is no longer actively manufactured.

Q: Are there packaging differences between the two parts?

A: The 794626-4 packaging is not specified in available documentation. The 3-794626-4 is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. Tape & Reel packaging is compatible with pick-and-place equipment and standard SMD assembly workflows.

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

A: Both the 794626-4 and 3-794626-4 operate across -40°C to 105°C, providing equivalent thermal performance for industrial and commercial applications.

Q: Are both connectors UL94 V-0 rated?

A: Yes. Both the 794626-4 and 3-794626-4 meet UL94 V-0 flammability requirements, ensuring equivalent fire safety performance in applications requiring this certification.

Q: What is the current rating for these connectors?

A: The current rating varies by wire gauge for both connectors. Specific current capacity is determined by the gauge of wire used in the mated cable assembly, not by the connector itself.

Q: Can the 3-794626-4 be used in RoHS-regulated applications?

A: Yes. The 3-794626-4 is ROHS3 compliant and is suitable for applications subject to RoHS regulations. The 794626-4 is RoHS non-compliant and should not be used in new designs requiring RoHS compliance.
