TE Connectivity AMP Connectors 1-794141-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-794141-3 is a rectangular connector socket contact designed for 18-22 AWG wire gauges with gold plating and crimp termination. This component belongs to the AMP-DUAC series and is classified as obsolete. Due to its obsolete product status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-794141-3 is based on the following critical parameters that must remain consistent across equivalent parts:

Mandatory Matching Parameters:

• Socket contact type (not pin)
• Crimp termination method
• Wire gauge range: 18-22 AWG
• Gold contact finish
• Contact finish thickness: 30.0µin (0.76µm)
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

The substitute part 1586315-4 satisfies all mandatory matching parameters. While it belongs to a different series (VAL-U-LOK versus AMP-DUAC) and uses stamped construction rather than an unspecified type, these differences do not affect the electrical or mechanical compatibility for socket contact applications within the specified wire gauge and termination requirements.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1586315-4 is suitable for applications requiring replacement of the obsolete 1-794141-3 based on the following engineering criteria:

Compliance and Regulatory Alignment: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with current regulatory requirements and environmental handling standards.

Electrical and Mechanical Equivalence: The substitute part maintains identical wire gauge specifications (18-22 AWG), contact finish composition (gold), and contact finish thickness (30.0µin / 0.76µm). These parameters directly determine electrical conductivity, contact resistance, and mechanical durability in crimp socket applications.

Product Availability: The 1586315-4 is classified as active product status with 3581 pieces in stock, compared to the obsolete 1-794141-3 with limited inventory of 748 pieces. Selection of the active substitute ensures long-term component availability and supply chain continuity.

Series and Construction Differences: The transition from AMP-DUAC to VAL-U-LOK series and from unspecified to stamped construction represents a design evolution within TE Connectivity's rectangular connector portfolio. These differences do not compromise functional equivalence for socket contact applications within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1586315-4 directly replace the 1-794141-3 in existing connector assemblies?

A: The 1586315-4 is electrically and mechanically equivalent for socket contact applications. Both parts accept 18-22 AWG wire gauges, use crimp termination, and maintain identical gold contact finish specifications. Compatibility depends on the specific connector housing and pin configuration of the assembly, which are not specified in the component parameters.

Q: What is the significance of the series difference between AMP-DUAC and VAL-U-LOK?

A: Series designation indicates product family grouping within TE Connectivity's connector portfolio. The VAL-U-LOK series represents a current-generation product line, while AMP-DUAC is legacy. The series difference does not affect the socket contact's electrical performance or mechanical compatibility with standard rectangular connector housings designed for 18-22 AWG crimp sockets.

Q: Does the stamped construction of the 1586315-4 affect performance compared to the unspecified type of the 1-794141-3?

A: Stamped construction is a manufacturing process that does not alter the electrical or mechanical specifications of the socket contact. Both parts deliver identical contact finish thickness (30.0µin), gold plating, and crimp termination performance. Stamped construction is a standard manufacturing method in modern connector production.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry MSL rating 1 (Unlimited). The 1-794141-3 is REACH Unaffected, while the 1586315-4 is listed as Vendor Undefined for REACH status. Both parts carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What is the inventory status difference, and does it affect selection?

A: The 1-794141-3 has 748 pieces in stock (obsolete status), while the 1586315-4 has 3581 pieces in stock (active status). For new designs or long-term production requirements, the active substitute ensures sustained component availability and eliminates future obsolescence risk.

Q: Are wire gauge specifications identical between the two parts?

A: Both parts are specified for 18-22 AWG wire gauges. The detailed description of the 1586315-4 references "18-22 AWG Crimp Stamped," confirming identical wire gauge compatibility. This parameter is critical for proper crimp contact and electrical performance.
