Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 787653-1 is determined by the following critical parameters that must remain constant across equivalent components:

• Connector Type & Configuration: Receptacle, 20-position, 2-row arrangement
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Electrical Interface: Board-to-board connectivity with outer shroud contacts
• Contact System: Gold finish at 30.0µin (0.76µm) thickness
• Mechanical Features: Board lock and latch lock mechanisms
• Series Compatibility: CHAMP .050 I series designation

The substitute part 787653-3 maintains all critical electrical and mechanical parameters while introducing SCA-2 board-to-board specification compliance and improved regulatory status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 787653-3

The 787653-3 serves as the direct substitute for the 787653-1 based on electrical and mechanical equivalence within the CHAMP .050 I series. Both connectors maintain identical pin count, row configuration, mounting orientation, and contact specifications.

Regulatory Compliance Considerations:

The 787653-3 provides enhanced regulatory compliance status compared to the main part. It carries ROHS3 compliance certification and REACH unaffected status, whereas the 787653-1 is not RoHS applicable and is REACH affected. For applications subject to environmental or procurement regulations, the 787653-3 presents a more favorable compliance profile.

Feature Differentiation:

The 787653-1 includes both board lock and latch lock features, while the 787653-3 incorporates board lock functionality. The 787653-3 additionally specifies SCA-2 board-to-board compatibility, indicating enhanced standardization for specific application environments.

Availability & Inventory:

Both parts are classified as obsolete. Current inventory availability shows 1146 pieces of the 787653-1 and 841 pieces of the 787653-3 in stock as new original components.

Frequently Asked Questions (FAQ)

Q: Can the 787653-3 directly replace the 787653-1 in existing designs?

A: Yes. Both connectors maintain identical electrical and mechanical specifications within the CHAMP .050 I series, including 20-position configuration, 2-row arrangement, through-hole right-angle solder termination, and gold contact finish at 30.0µin thickness. The connectors are functionally equivalent for board-to-board applications.

Q: What is the difference between the latch lock and board lock features?

A: The 787653-1 includes both board lock and latch lock mechanisms, while the 787653-3 includes board lock only. Both features provide mechanical retention; the specific requirement depends on application-level design specifications.

Q: Does the SCA-2 designation on the 787653-3 affect compatibility?

A: The SCA-2 designation indicates compliance with a specific board-to-board standard. This does not prevent substitution; it indicates the 787653-3 meets additional standardization criteria. Compatibility is maintained across both parts for standard board-to-board applications.

Q: Are there RoHS or REACH compliance implications for substitution?

A: The 787653-3 is ROHS3 compliant and REACH unaffected, while the 787653-1 is not RoHS applicable and is REACH affected. For applications requiring environmental compliance certification, the 787653-3 is the appropriate selection.

Q: What is the moisture sensitivity level for these connectors?

A: Both the 787653-1 and 787653-3 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts still in production?

A: Both connectors are classified as obsolete. Selection between them should be based on regulatory compliance requirements and specific feature needs rather than production status.
