Engineering Selection Recommendations

TE Connectivity 4-641210-2 (Direct Substitute)

The 4-641210-2 is a direct substitute for the 1-641210-2 within the same manufacturer series. Both parts maintain identical electrical and mechanical specifications including 12-position configuration, 0.156" pitch, through-hole right-angle mounting, and 600VAC voltage rating. The primary distinction is packaging format (bulk) and compliance status. The 4-641210-2 carries ROHS3 compliance and REACH Unaffected certification, whereas the main part is RoHS non-compliant. Selection of the 4-641210-2 is appropriate for applications requiring regulatory compliance with modern environmental standards. Contact finish on the post differs (Tin versus Tin-Lead), which does not affect electrical performance for this connector class.

Molex 0026481126 (Similar Substitute)

The Molex 0026481126 provides cross-manufacturer substitution capability within the same connector category. This part maintains the critical parameters of 12-position configuration, 0.156" pitch, through-hole right-angle mounting, and friction lock fastening. The 0026481126 operates within the KK396 and 41672 series and includes breakaway header functionality. Mechanical dimensions differ: contact lengths and insulation height are greater (0.450" mating contact length versus 0.400", and 0.355" insulation height versus 0.300"). These dimensional differences require verification of mechanical fit within the target application's PCB layout and mating cavity. The Molex part carries ROHS3 compliance and REACH Unaffected status. Voltage and operating temperature specifications are not provided for this part; applications requiring 600VAC or -55°C to 105°C operation must confirm compatibility through Molex technical documentation.

Selection Criteria Summary

• For RoHS3 compliance requirement: Select 4-641210-2 or 0026481126
• For identical TE Connectivity MTA-156 series continuity: Select 4-641210-2
• For cross-manufacturer flexibility with breakaway option: Select 0026481126
• For mechanical envelope constraints: Verify dimensional compatibility; 1-641210-2 and 4-641210-2 are dimensionally identical; 0026481126 has larger contact lengths and insulation height

Frequently Asked Questions (FAQ)

Q: Can the 4-641210-2 be used as a direct replacement for the 1-641210-2 in existing designs?

A: Yes. The 4-641210-2 maintains identical electrical and mechanical specifications including 12-position configuration, 0.156" pitch, through-hole right-angle mounting, solder termination, and 600VAC voltage rating. The parts are mechanically and electrically interchangeable. The primary difference is packaging and RoHS compliance status.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: Both finishes provide adequate electrical conductivity and corrosion resistance for this connector class. Tin-Lead (main part) and Tin (substitute parts) are both acceptable for 600VAC applications. The selection between these finishes is typically driven by manufacturing process and environmental compliance requirements rather than electrical performance.

Q: Can the Molex 0026481126 be used in place of the TE Connectivity parts?

A: The Molex 0026481126 is electrically and functionally compatible for the same connector pitch, position count, and mounting style. However, mechanical dimensions differ: the Molex part has longer contact lengths (0.450" versus 0.400") and greater insulation height (0.355" versus 0.300"). These dimensional differences require verification that the mating cavity and PCB layout accommodate the larger envelope. Additionally, voltage and operating temperature specifications are not provided for the Molex part; applications with specific electrical requirements must confirm compatibility.

Q: What does "Shrouded - 1 Wall" mean?

A: Shrouding refers to the plastic housing that surrounds the connector contacts. "1 Wall" indicates that the shroud covers one side of the connector, providing polarization and protection while allowing access from the opposite side. All three parts in this comparison maintain this same shrouding configuration.

Q: Are there any differences in the insulation material between the parts?

A: The TE Connectivity parts (1-641210-2 and 4-641210-2) use Thermoplastic Glass Filled insulation, while the Molex 0026481126 uses Polyester insulation. Both materials are UL94 V-0 rated for flammability. The material difference does not affect electrical performance but may influence mechanical properties and environmental resistance. Applications with specific material requirements should confirm suitability.

Q: What is the difference between "Board to Cable/Wire" and "Board to Board or Cable" style?

A: "Board to Cable/Wire" indicates the connector is designed to mate with cable assemblies or individual wires. "Board to Board or Cable" indicates the connector can mate with either PCB-mounted connectors or cable assemblies. The Molex part offers greater flexibility in mating options, while the TE Connectivity parts are optimized for cable/wire connections.

Q: Does the breakaway feature on the Molex part affect compatibility?

A: The breakaway feature on the Molex 0026481126 allows individual positions to be separated from the main connector body. This feature does not prevent the part from functioning as a standard 12-position header. The breakaway capability provides additional flexibility for applications requiring partial connector separation, but it is not required for standard operation.

Q: What is the significance of the different inventory levels?

A: Inventory levels (1094 pcs for 1-641210-2, 1571 pcs for 4-641210-2, and 1401 pcs for 0026481126) indicate current stock availability. These levels are subject to change and should not be used as a primary selection criterion. Inventory information is provided for procurement planning purposes only.

Q: Are all three parts suitable for industrial applications?

A: Yes. All three parts are rated for general purpose and industrial applications. The TE Connectivity parts explicitly list these applications. The Molex part lists automotive, general purpose, industrial, medical, and telecommunications applications, indicating broader application scope.
