Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 787653-2 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: Receptacle
• Number of Positions: 20
• Number of Rows: 2
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Connector Style: Outer Shroud Contacts
• Contact Finish: Gold

Substitute Classification:

Direct Manufacturer Equivalents (TE Connectivity family):

• 787653-4: Shares identical base product number (787653), same series (CHAMP .050 I), and all primary compatibility parameters. Includes SCA-2 board-to-board specification and RoHS3 compliance.
• 787653-3: Shares identical base product number (787653), same series (CHAMP .050 I), and all primary compatibility parameters. Includes SCA-2 board-to-board specification and RoHS3 compliance.

Cross-Manufacturer Alternative (Different manufacturer):

• DX10A-20S(50): Hirose Electric equivalent meeting core electrical and mechanical parameters (20 positions, 2 rows, through-hole right-angle solder termination, outer shroud contacts, gold finish). Classified as active product status with RoHS compliance. Mounting type includes panel mount capability in addition to through-hole configuration.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Within TE Connectivity Product Line:

Parts 787653-4 and 787653-3 are functionally equivalent to 787653-2 within the CHAMP .050 I series. Both substitute parts achieve RoHS3 compliance, whereas the original part carries no RoHS designation. Both maintain identical electrical and mechanical specifications including 20-position configuration, 2-row layout, through-hole right-angle solder termination, and gold contact finish at 30.0µin thickness.

For Cross-Manufacturer Substitution:

The Hirose DX10A-20S(50) provides functional equivalence across core parameters: 20-position receptacle, 2-row configuration, through-hole right-angle solder termination, and outer shroud gold-plated contacts. This part carries active product status and RoHS compliance. The contact finish thickness differs at 7.87µin compared to 30.0µin on the TE Connectivity parts. The DX10A-20S(50) includes panel mount capability in addition to through-hole mounting, providing design flexibility for applications requiring alternative mounting configurations.

Compliance Considerations:

All substitute parts maintain MSL 1 (Unlimited) rating, matching the original part's moisture sensitivity classification. The transition from obsolete to active product status with the Hirose alternative ensures long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can 787653-4 and 787653-3 be used interchangeably with 787653-2?

A: Yes. Both parts share the same base product number (787653), series designation (CHAMP .050 I), and all critical electrical and mechanical parameters including 20-position configuration, 2-row layout, through-hole right-angle solder termination, and gold contact finish. The primary difference is RoHS3 compliance status on the substitute parts.

Q: What is the difference between 787653-4 and 787653-3?

A: Both parts are functionally equivalent within the CHAMP .050 I series with identical electrical and mechanical specifications. The documented difference is in the Features parameter: 787653-4 includes both Board Lock and Latch Lock features, while 787653-3 includes Board Lock only. Packaging differs, with 787653-4 supplied in Tray format.

Q: Is the Hirose DX10A-20S(50) a suitable replacement for the TE Connectivity 787653-2?

A: The DX10A-20S(50) meets all core electrical and mechanical requirements: 20-position receptacle, 2-row configuration, through-hole right-angle solder termination, outer shroud contacts, and gold finish. The part is active status with RoHS compliance. Contact finish thickness is thinner (7.87µin versus 30.0µin). The DX10A-20S(50) includes panel mount capability as an additional mounting option. Cross-manufacturer substitution requires verification of mechanical fit and mating interface compatibility with existing connector plugs.

Q: Why is the original 787653-2 classified as obsolete?

A: Product obsolescence indicates the part is no longer manufactured by TE Connectivity. Substitute parts 787653-4 and 787653-3 within the same series provide equivalent functionality with updated compliance certifications. The Hirose DX10A-20S(50) offers an active-status alternative from a different manufacturer.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 787653-4 is supplied in Tray packaging, while 787653-2 and 787653-3 have no specified packaging designation in the provided data. Packaging format may affect procurement quantities and handling procedures but does not impact electrical or mechanical compatibility.

Q: What is the significance of the contact finish thickness difference?

A: The original 787653-2 and its direct substitutes (787653-4, 787653-3) specify 30.0µin (0.76µm) gold contact finish thickness. The Hirose DX10A-20S(50) specifies 7.87µin (0.200µm). Both thicknesses provide gold plating for corrosion resistance and electrical conductivity. The thicker finish on TE Connectivity parts may provide extended contact life in high-cycle mating applications, while the thinner finish on the Hirose part meets standard connector specifications.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. The original 787653-2 and all substitute parts (787653-4, 787653-3, DX10A-20S(50)) carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
