TE Connectivity AMP Connectors 794620-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 794620-4 is a rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This shrouded 4-position connector operates within the Micro MATE-N-LOK series and features male pin contacts with gold-plated mating surfaces and tin-lead post finishes. The connector maintains an active product status and is widely used in general-purpose applications requiring reliable board-level interconnection with a 250V voltage rating and operating temperature range of -40°C to 105°C.

Identifying equivalent and substitute parts is necessary when addressing specific packaging requirements, compliance certifications, or inventory availability while maintaining identical electrical and mechanical functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 794620-4 connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

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

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Series designation (Micro MATE-N-LOK)

Allowable Variation Parameters:

• Packaging format (bulk or tray)
• Contact finish on post (Tin-Lead or Tin)
• RoHS compliance status
• REACH compliance status

Parts meeting all electrical and mechanical compatibility parameters while differing only in packaging or compliance certifications are classified as direct substitutes.

Engineering Selection Recommendations

Primary Selection: 794620-4

The 794620-4 is the original specification part and maintains active product status. Selection of this part number is appropriate for applications where bulk packaging is acceptable and RoHS non-compliance does not conflict with end-use requirements or regulatory constraints.

Alternative Selection: 3-794620-4

The 3-794620-4 is a direct functional equivalent offering identical electrical and mechanical performance. This part number differs only in packaging format (tray versus bulk) and RoHS compliance status (RoHS Compliant). Selection of the 3-794620-4 is appropriate for applications requiring:

• RoHS compliance certification
• Tray packaging format for automated assembly processes
• Supply chain requirements mandating compliant component documentation

Both part numbers are manufactured by TE Connectivity AMP Connectors, maintain active product status, and deliver equivalent performance across all critical electrical and mechanical parameters. The choice between these part numbers is determined by packaging requirements and regulatory compliance obligations specific to the end application.

Frequently Asked Questions (FAQ)

Q: Are 794620-4 and 3-794620-4 electrically interchangeable?

A: Yes. Both connectors feature identical contact types, pin counts, pitch specifications, voltage ratings, and operating temperature ranges. They deliver equivalent electrical performance in board-to-cable/wire applications.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format and RoHS compliance status. The 794620-4 is supplied in bulk packaging and is RoHS non-compliant. The 3-794620-4 is supplied in tray packaging and is RoHS Compliant. All electrical and mechanical specifications are identical.

Q: Can I use 3-794620-4 as a direct replacement for 794620-4 on an existing PCB design?

A: Yes. The 3-794620-4 is mechanically and electrically equivalent. The connector footprint, mounting orientation (through-hole, right-angle), shrouding configuration, and contact arrangement are identical. No PCB redesign is required.

Q: Does the post finish difference (Tin-Lead versus Tin) affect compatibility?

A: No. The post finish difference does not affect electrical or mechanical compatibility. Both finishes are suitable for solder termination. The post finish variation reflects manufacturing process differences and does not impact connector performance or mating characteristics.

Q: Which part should I specify for a new design?

A: Specify the part number that aligns with your regulatory and packaging requirements. For RoHS-compliant applications, specify 3-794620-4. For applications without RoHS requirements, either part number is acceptable. Verify packaging format compatibility with your assembly process.

Q: Are there any performance differences between bulk and tray packaging?

A: No. Packaging format does not affect connector performance. Bulk and tray packaging are alternative distribution methods for identical components. Selection is based on inventory management, assembly automation requirements, and supply chain logistics.

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

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.
