Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 794577-1 is based on strict alignment of the following critical parameters:

Substitution Criteria:

• Pin or Socket configuration: Pin contact
• Contact Termination method: Crimp
• Wire Gauge compatibility: 18-22 AWG
• Contact Finish material: Tin
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)
• Regulatory classification: EAR99 ECCN

The substitute part 1586314-3 satisfies all mandatory substitution criteria. While the substitute belongs to the VAL-U-LOK series rather than AMP-DUAC, and carries an active product status, it maintains functional equivalence through identical electrical and mechanical parameters within the specified wire gauge range.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1586314-3 serves as the direct functional equivalent for the obsolete 794577-1. Selection of the substitute part is supported by the following factors:

Product Status Alignment: The substitute part maintains active production status, ensuring long-term supply chain availability and continued manufacturing support from TE Connectivity.

Regulatory Compliance: Both parts maintain identical RoHS3 compliance and EAR99 ECCN classification, satisfying regulatory requirements for new designs and production environments.

Electrical and Mechanical Compatibility: The substitute part preserves all critical electrical parameters including wire gauge range (18-22 AWG), contact termination method (crimp), and contact finish material (tin). Moisture sensitivity level remains unchanged at MSL 1 (Unlimited), indicating no special storage or handling requirements.

Series Transition: While the substitute part belongs to the VAL-U-LOK series rather than the original AMP-DUAC series, the functional parameters remain equivalent for power connector applications requiring pin contacts with crimp termination.

Frequently Asked Questions (FAQ)

Q: Can the 1586314-3 directly replace the 794577-1 in existing connector assemblies?

A: The 1586314-3 maintains identical electrical and mechanical parameters for wire gauge, termination method, and contact finish. Compatibility depends on the physical connector housing and mating interface specifications, which are not provided in this reference. Verify housing compatibility with the connector assembly documentation.

Q: What is the significance of the series change from AMP-DUAC to VAL-U-LOK?

A: The series designation indicates the connector family and housing design. While both parts are pin contacts with crimp termination, the series change reflects a product line transition. Connector housing compatibility must be verified independently to ensure proper mating with existing receptacle components.

Q: Are there any differences in wire gauge handling between the two parts?

A: Both parts support identical wire gauge specifications of 18-22 AWG. No adjustment to wire preparation or crimping procedures is required based on this parameter.

Q: Does the substitute part maintain the same RoHS and regulatory compliance?

A: Yes. The 1586314-3 maintains ROHS3 compliance and EAR99 ECCN classification identical to the original part. No regulatory re-qualification is necessary for applications already approved for the 794577-1.

Q: What is the inventory status difference between these parts?

A: The original 794577-1 has 841 pieces in stock with obsolete status. The substitute 1586314-3 has 10,505 pieces in stock with active product status, providing superior long-term supply availability.

Q: Are there any moisture sensitivity or storage requirement differences?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no special moisture control or storage requirements. Standard handling procedures apply to both components.
