3M 10126-72B2VC Equivalent & Substitute Parts

Part Overview

The 3M 10126-72B2VC is a 26-position board-to-board plug connector featuring right-angle solder termination, panel mount configuration, and shielded design with board lock functionality. This connector is part of the 101 Mini D Ribbon (MDR) series and utilizes center strip contacts with gold-plated termination.

The 10126-72B2VC is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Substitute Part Grouping Explanation

Substitution for the 10126-72B2VC is determined by alignment across the following critical parameters: connector position count (26), row configuration (2), mounting orientation (right angle, panel mount, through hole), termination method (solder), housing shell size (M2.6), contact finish (gold), and moisture sensitivity rating (MSL 1).

Two substitute options are identified:

Direct 3M Series Substitute: The 10126-72B2PC maintains identical electrical and mechanical specifications to the main part while offering active product status and RoHS compliance.

Cross-Manufacturer Substitute: The Hirose DX10G1M-26SE(50) provides functional equivalence through matching position count, row configuration, mounting type, termination method, and housing shell specification. This part operates within the Miniature High Density (HD) connector category and maintains the same contact finish and moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement within existing 3M 101 series designs: The 3M 10126-72B2PC is the primary substitute. This part maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance, eliminating the regulatory constraints associated with the obsolete 10126-72B2VC.

For cross-manufacturer substitution: The Hirose DX10G1M-26SE(50) provides functional equivalence when connector type flexibility is acceptable. This part is classified as a receptacle (versus the plug configuration of the main part), requiring mating with a corresponding plug connector. The Hirose part maintains all critical mechanical parameters, solder termination, and compliance certifications. Inventory availability for the Hirose part exceeds that of both 3M options.

Selection between the 3M 10126-72B2PC and Hirose DX10G1M-26SE(50) depends on design requirements regarding connector gender (plug versus receptacle) and manufacturer preference within the system architecture.

Frequently Asked Questions (FAQ)

Q: Can the 3M 10126-72B2PC directly replace the 10126-72B2VC in existing assemblies?

A: Yes. The 10126-72B2PC is electrically and mechanically identical to the 10126-72B2VC. Both are 26-position plugs with right-angle solder termination, panel mount configuration, and M2.6 housing shells. The primary differences are product status (active versus obsolete) and RoHS compliance.

Q: What is the key difference between the 3M and Hirose substitutes?

A: The 3M 10126-72B2PC is a plug connector, matching the main part's gender. The Hirose DX10G1M-26SE(50) is a receptacle connector. Both share identical position counts, row configurations, mounting types, and termination methods. Connector gender selection depends on the mating interface requirements of your application.

Q: Are there any compatibility concerns when substituting the Hirose DX10G1M-26SE(50)?

A: The Hirose part requires a mating plug connector. Verify that your system design accommodates receptacle-type connectors. All mechanical parameters, including housing shell size (M2.6), mounting orientation (right angle, panel mount, through hole), and solder termination, are compatible with the main part's specifications.

Q: Does the Hirose substitute maintain the shielded feature of the original connector?

A: The Hirose DX10G1M-26SE(50) includes board lock functionality but does not specify shielding in the provided parameters. If shielding is a critical design requirement, the 3M 10126-72B2PC is the recommended substitute, as it explicitly maintains the shielded feature of the original 10126-72B2VC.

Q: What are the RoHS compliance implications of each substitute?

A: The 3M 10126-72B2PC is RoHS Compliant. The Hirose DX10G1M-26SE(50) is ROHS3 Compliant. Both substitutes meet current RoHS requirements, whereas the original 10126-72B2VC is RoHS non-compliant. Selection of either substitute improves regulatory compliance for new designs or production runs.
