Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 794578-1 are identified based on strict alignment with the following critical parameters:

Substitution Criteria:

• Pin or Socket configuration: Pin
• Contact Termination method: Crimp
• Wire Gauge range: 22-26 AWG
• Contact Finish: Tin
• Moisture Sensitivity Level: 1 (Unlimited)
• Export Classification: EAR99
• HTSUS Code: 8536.90.4000

The substitute part 794957-3 satisfies all substitution criteria. While the substitute belongs to a different connector series (VAL-U-LOK versus AMP-DUAC), it maintains identical electrical and mechanical specifications for the contact interface, termination method, and wire gauge compatibility. The substitute part carries active product status and RoHS compliance certification, providing enhanced availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 794957-3 is suitable for applications requiring replacement of the obsolete 794578-1. Selection is based on the following factors:

Product Status Alignment: The main part 794578-1 carries obsolete status, indicating discontinued manufacturing and limited availability. The substitute 794957-3 maintains active product status, ensuring continued procurement viability and supply chain reliability.

Compliance and Certification: The substitute part carries RoHS compliance certification, meeting current regulatory requirements for restricted substances in electrical and electronic equipment. Both parts share identical export classification (EAR99) and harmonized tariff codes, maintaining consistent regulatory treatment.

Electrical and Mechanical Compatibility: The substitute part maintains identical specifications across all critical contact interface parameters: pin configuration, crimp termination, 22-26 AWG wire gauge range, and tin contact finish. These parameters determine functional compatibility within connector assemblies.

Packaging Consideration: The substitute part is supplied in Cut Tape (CT) packaging, which differs from the main part's unspecified packaging. Procurement processes must account for packaging format differences when transitioning to substitute components.

Frequently Asked Questions (FAQ)

Q: Can 794957-3 directly replace 794578-1 in existing connector assemblies?

A: The 794957-3 maintains identical pin contact specifications, crimp termination, wire gauge range (22-26 AWG), and tin finish. Compatibility depends on the connector housing and assembly design. The substitute belongs to the VAL-U-LOK series while the main part belongs to the AMP-DUAC series. Verify housing compatibility before implementation.

Q: What is the significance of the obsolete product status for 794578-1?

A: Obsolete status indicates the manufacturer has discontinued production. This creates supply constraints and limits future procurement options. The substitute 794957-3 carries active status, ensuring ongoing availability and manufacturing support.

Q: Are there differences in moisture sensitivity between the main part and substitute?

A: Both parts carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints for either component.

Q: Does the substitute part meet current regulatory requirements?

A: The substitute part 794957-3 carries RoHS compliance certification, meeting current restrictions on hazardous substances. The main part's RoHS status is not specified. Both parts share identical export classification (EAR99) and HTSUS codes.

Q: What packaging format is used for the substitute part?

A: The substitute part 794957-3 is supplied in Cut Tape (CT) packaging. Verify that your procurement and assembly processes accommodate this packaging format.

Q: Are the contact finish specifications identical between both parts?

A: Both parts feature tin contact finish. Contact finish thickness is not specified for either part. The tin finish provides corrosion resistance and solderability for power applications.

Q: What wire gauge range is supported by the substitute part?

A: The substitute part 794957-3 supports the identical 22-26 AWG wire gauge range as the main part 794578-1, ensuring compatibility with existing wire specifications in power connector applications.
