Key Parameters

Substitute Part Grouping Explanation

The substitute part 5787131-1 is classified as a direct equivalent to the main part 787131-1 based on the following critical parameters that determine substitution eligibility:

Electrical and Mechanical Compatibility Parameters:

• Number of Positions: 50 (identical)
• Number of Rows: 2 (identical)
• Connector Type: Plug (identical)
• Connector Style: Center Strip Contacts (identical)
• Mounting Type: Free Hanging (In-Line) (identical)
• Termination Method: IDC (identical)
• Series: CHAMP .031 (identical)
• Contact Finish: Gold (identical)
• Contact Finish Thickness: 30.0µin (0.76µm) (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The substitute part maintains full compatibility across all specified electrical and mechanical parameters. The primary differences are packaging configuration and RoHS compliance status.

Engineering Selection Recommendations

For RoHS-Compliant Applications: The substitute part 5787131-1 is the appropriate selection when RoHS compliance is required. This part maintains identical electrical and mechanical specifications while meeting RoHS compliance requirements. The higher inventory availability (1778 units) of the substitute part also provides improved supply chain reliability.

For Non-Compliant or Legacy Applications: The main part 787131-1 remains suitable for applications where RoHS compliance is not a requirement. Both parts are active in production status and maintain full functional equivalence.

Packaging Considerations: The substitute part 5787131-1 is supplied in box packaging, whereas the main part packaging specification is not provided. Selection should account for downstream assembly and handling requirements.

Frequently Asked Questions (FAQ)

Q: Are 787131-1 and 5787131-1 electrically interchangeable?

A: Yes. Both parts are 50 position plug connectors with identical electrical specifications, including center strip contacts, gold plating at 30.0µin thickness, and IDC termination. They are fully interchangeable from an electrical standpoint.

Q: What is the primary difference between these two parts?

A: The primary difference is RoHS compliance status. The 5787131-1 is RoHS compliant, while the 787131-1 is RoHS non-compliant. Both parts are mechanically and electrically identical across all specified parameters.

Q: Can I substitute 5787131-1 for 787131-1 in existing designs?
