Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the N10280-52B2VC is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 80
• Number of Rows: 2
• Connector Type: Receptacle
• Termination: Solder
• Mounting Type: Right Angle configuration
• Features: Shielded capability

Secondary Compatibility Factors:

• Contact Finish: Gold plating
• Moisture Sensitivity Level: MSL 1
• Electrical Classification: D-Sub category

Substitute parts are grouped into two categories based on form factor and mounting compatibility:

Category 1 - Direct Form Factor Substitutes: Parts maintaining panel mount, through hole, right angle solder configuration with outer shroud contacts and board lock features.

Category 2 - Functional Equivalents: Parts with identical electrical specifications and 80-position, 2-row configuration but differing in mounting type or connector style, suitable for applications where mechanical form factor flexibility exists.

Parameter Comparison

Engineering Selection Recommendations

N10280-52B2PC (3M Direct Equivalent)

This part represents the primary substitute for the obsolete N10280-52B2VC. It maintains identical mechanical and electrical specifications including panel mount configuration, outer shroud contacts, board lock feature, and 30.0µin gold contact finish. The N10280-52B2PC is active in production status and achieves RoHS compliance, making it the preferred choice for new designs and ongoing procurement where form factor compatibility is required.

787394-8 (TE Connectivity AMPLIMITE .050 III)

This TE Connectivity part satisfies the core electrical requirements of 80 positions, 2 rows, receptacle configuration, and solder termination. The connector employs a D-Type style with board edge mounting rather than panel mount. Substitution is viable for applications where the board edge mounting configuration is mechanically compatible with the system design. The part is active in production and maintains shielded features with gold contact finish.

787915-1 (TE Connectivity CHAMP .050 I)

This board-to-board receptacle connector provides functional equivalence for 80-position, 2-row solder termination applications. The mounting type differs from the original part, being configured for through hole board-to-board connection without panel mount capability. This substitute is applicable only in designs where board-to-board mounting replaces the original panel mount requirement. The part is active in production with board lock and latch lock features.

Compliance Considerations

The N10280-52B2PC is the only substitute achieving RoHS compliance among the available options. For applications subject to RoHS regulatory requirements, this part is the mandatory selection. The TE Connectivity alternatives (787394-8 and 787915-1) remain RoHS non-compliant and are suitable only for legacy systems or applications exempt from RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can the N10280-52B2PC directly replace the N10280-52B2VC without PCB modification?

A: Yes. The N10280-52B2PC maintains identical mechanical specifications including panel mount, through hole, right angle solder configuration, outer shroud contacts, M2.6 housing/shell flange, and board lock features. No PCB layout or mechanical redesign is required.

Q: What is the primary difference between N10280-52B2PC and the original N10280-52B2VC?

A: The N10280-52B2PC achieves RoHS compliance while the original part does not. Both parts are functionally and mechanically equivalent. The N10280-52B2PC is the active production part.

Q: Are the TE Connectivity parts (787394-8 and 787915-1) direct mechanical replacements?

A: No. The 787394-8 uses board edge mounting instead of panel mount. The 787915-1 is configured for board-to-board connection. Both require mechanical redesign of the mounting interface. These parts are functional equivalents only when the application can accommodate the different mounting configuration.

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

A: The N10280-52B2VC and N10280-52B2PC both specify 30.0µin (0.76µm) gold finish thickness. The 787915-1 specifies 15.0µin (0.38µm). Contact finish thickness affects durability and wear resistance in mating cycles. The thicker finish of the 3M parts provides extended contact life.

Q: Which substitute part should be selected for new product designs?

A: The N10280-52B2PC is the recommended selection for new designs. It is the active production equivalent with identical form factor, RoHS compliance, and maintained specifications. The TE Connectivity alternatives should be considered only when mechanical form factor constraints require board edge or board-to-board mounting configurations.

Q: Are all substitute parts available in the same packaging format?

A: The N10280-52B2VC and N10280-52B2PC packaging is not specified in the data. The 787394-8 is supplied in tube packaging. Verify packaging requirements with the supplier for procurement planning.

Q: What is the MSL rating significance for these connectors?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special humidity control measures and do not require baking prior to reflow soldering.
