Key Parameters

Substitute Part Grouping Explanation

Substitution of the 10120-72B2VC is based on the following critical parameters that must remain consistent:

• Connector Type & Series: Plug connector within the 3M 101 Mini D Ribbon (MDR) series
• Position Count & Row Configuration: 20 positions arranged in 2 rows
• Mounting & Termination: Panel mount, through-hole, right-angle solder termination
• Connector Style: Center strip contacts with board lock and shielding
• Contact Specifications: Gold finish at 30.0µin (0.76µm) thickness
• Housing Specification: M2.6 flange feature

The substitute part 10120-52B2PC maintains all critical electrical and mechanical parameters required for functional equivalence. The primary distinction is the change from board-to-board type to panel mount type and the transition from obsolete to active product status with improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 10120-52B2PC is the manufacturer-recommended substitute for the obsolete 10120-72B2VC. Selection of this substitute is supported by the following factors:

Product Status: The 10120-52B2PC maintains active product status, ensuring ongoing availability, technical support, and supply chain continuity compared to the obsolete 10120-72B2VC.

Regulatory Compliance: The 10120-52B2PC achieves ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The original part is RoHS non-compliant, which may present compliance challenges for new designs or systems subject to regulatory restrictions.

Electrical & Mechanical Equivalence: Both parts maintain identical specifications for connector type, position count, row configuration, mounting method, termination style, contact finish, and housing dimensions. This ensures direct functional compatibility in existing circuit board layouts and connector mating interfaces.

Inventory & Availability: The 10120-52B2PC is available in higher inventory quantities (1212 pcs) compared to the main part (714 pcs), supporting both immediate procurement needs and long-term supply security.

Frequently Asked Questions (FAQ)

Q: Can the 10120-52B2PC be used as a direct replacement for the 10120-72B2VC?

A: Yes. Both connectors share identical electrical and mechanical specifications including 20-position configuration, 2-row arrangement, center strip contacts, gold contact finish, board lock and shielding features, and M2.6 housing dimensions. The primary differences are product status and regulatory compliance certifications.

Q: What is the difference between board-to-board type and panel mount type in these connectors?

A: The 10120-72B2VC is specified as board-to-board type, while the 10120-52B2PC is specified as panel mount type. Both maintain identical mounting configurations (panel mount, through-hole, right-angle). The type designation reflects the intended application context rather than a functional difference in the connector itself.

Q: Are there compliance considerations when substituting the 10120-72B2VC with the 10120-52B2PC?

A: Yes. The 10120-52B2PC is ROHS3 compliant and REACH unaffected, while the 10120-72B2VC is RoHS non-compliant. For applications subject to RoHS or REACH regulations, the 10120-52B2PC is the appropriate selection. For legacy systems without regulatory constraints, both parts are functionally equivalent.

Q: Does packaging differ between these two connectors?

A: The 10120-52B2PC is supplied in bulk packaging. The 10120-72B2VC packaging specification is not provided. For procurement planning, confirm packaging requirements with your supplier, as this may affect order quantities and handling procedures.

Q: Are the contact finish specifications identical?

A: Yes. Both connectors feature gold contact finish at 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and corrosion resistance characteristics.
