TE Connectivity AMP Connectors 794682-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 794682-2 is a rectangular connector header classified as a Micro MATE-N-LOK series component. This through-hole mounted connector features a vertical orientation with 2 positions arranged in 2 rows, designed for board-to-cable/wire applications. The connector employs shrouded 4-wall construction with solder termination and locking ramp fastening.

The 794682-2 carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical and mechanical compatibility across all critical parameters including connector geometry, contact configuration, termination method, and environmental ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 794682-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

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

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting method (Through Hole)
• Termination method (Solder)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Locking Ramp)
• Series designation (Micro MATE-N-LOK)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

Packaging Considerations:

• Substitute parts may differ in packaging format (bulk versus tray) without affecting functional compatibility
• Contact finish on post terminals may vary between Tin-Lead and Tin formulations while maintaining electrical performance

The substitute part 3-794682-2 maintains complete equivalence across all critical electrical and mechanical parameters, with the primary distinction being active product status and RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 3-794682-2 serves as a direct functional equivalent to the obsolete 794682-2 across all critical electrical and mechanical parameters. Selection of the substitute part is supported by the following engineering considerations:

Product Status Alignment: The 3-794682-2 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete 794682-2.

Regulatory Compliance: The substitute part 3-794682-2 carries RoHS Compliant certification, meeting current environmental and material restriction requirements. The main part 794682-2 lists RoHS status as not applicable, indicating it predates RoHS compliance requirements. Both parts maintain identical UL94 V-0 flammability ratings and equivalent electrical performance specifications.

Contact Finish Specification: The post terminal contact finish differs between Tin-Lead (794682-2) and Tin (3-794682-2). Both finishes maintain the specified 100.0µin (2.54µm) thickness and provide equivalent solder joint reliability and electrical conductivity for through-hole termination applications.

Packaging Format: The substitute part is supplied in tray packaging versus bulk format for the main part. This packaging difference does not affect functional performance and may provide improved handling and inventory management benefits.

Electrical and Mechanical Equivalence: All critical parameters including connector geometry, contact configuration, row spacing, mounting method, termination approach, and environmental ratings remain identical between the two parts, confirming direct substitutability for board-to-cable/wire applications within the specified operating temperature range of -40°C to 105°C at 250V.

Frequently Asked Questions (FAQ)

Q: Can the 3-794682-2 be used as a direct replacement for the 794682-2 in existing designs?

A: Yes. The 3-794682-2 maintains complete electrical and mechanical equivalence to the 794682-2 across all critical parameters including connector type, contact configuration, row spacing, mounting method, termination, shrouding, and environmental ratings. Direct substitution is supported without design modification.

Q: What is the significance of the different contact finish on the post terminals?

A: The 794682-2 uses Tin-Lead finish while the 3-794682-2 uses Tin finish on post terminals. Both maintain identical thickness specifications (100.0µin / 2.54µm) and provide equivalent solder joint reliability and electrical performance for through-hole solder termination. The Tin finish on the substitute part reflects current manufacturing standards and RoHS compliance requirements.

Q: Does the RoHS Compliant status of the 3-794682-2 affect compatibility with the 794682-2?

A: No. RoHS compliance status does not affect electrical or mechanical compatibility. The 3-794682-2 RoHS Compliant designation indicates adherence to current environmental material restriction standards. Both parts maintain identical electrical specifications, operating temperature ranges, voltage ratings, and contact materials.

Q: Are there packaging considerations when switching from 794682-2 to 3-794682-2?

A: The 794682-2 is supplied in bulk packaging while the 3-794682-2 is supplied in tray packaging. This difference affects handling and inventory management but does not impact functional performance or electrical characteristics. Component specifications remain identical regardless of packaging format.

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