Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 4-644633-2 are selected based on strict electrical and mechanical parameter alignment. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 12
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Friction Lock
• Shrouding: Shrouded - 1 Wall
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

All substitute parts listed (Molex 0026605128, 0417920521, and 0417920538) meet these core electrical and mechanical requirements. The substitute parts are manufactured by Molex and belong to the KK396 and 41792 series families. All substitute parts maintain active product status and comply with ROHS3 and REACH requirements, ensuring long-term availability and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 4-644633-2 is classified as obsolete, necessitating the use of active substitute parts for new designs and ongoing production support. All three Molex substitute parts (0026605128, 0417920521, and 0417920538) are active products with confirmed long-term availability.

Compliance and Certification Alignment: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part. All parts carry UL94 V-0 flammability ratings, ensuring equivalent safety performance in industrial and general-purpose applications.

Mechanical and Electrical Compatibility: The substitute parts maintain identical pitch spacing (0.156"), position count (12), row configuration (1), and core connector architecture. Contact length for mating surfaces remains constant at 0.450" (11.43mm). The primary dimensional variance exists in contact post length and insulation height, with substitute parts featuring 0.156" (3.96mm) post length and 0.394" (10.00mm) insulation height compared to the original part's 0.125" (3.18mm) and 0.300" (7.62mm) respectively.

Contact Finish Considerations: Molex 0417920521 and 0417920538 feature gold mating contact finish matching the original part's specification. Molex 0026605128 utilizes tin mating contact finish. All substitute parts employ tin post finish consistent with the original design.

Product Status Advantage: Selection of active Molex substitute parts ensures continued component availability, technical support, and supply chain stability compared to the obsolete TE Connectivity original part.

Frequently Asked Questions (FAQ)

Q: Can Molex 0026605128, 0417920521, and 0417920538 be used interchangeably with TE Connectivity 4-644633-2?

A: All three Molex parts meet the critical electrical and mechanical parameters required for substitution, including pitch spacing, position count, mounting type, and fastening mechanism. Physical dimensional differences exist in contact post length and insulation height. Design validation is required to confirm compatibility with specific board layouts and mating connector geometries.

Q: What is the primary difference between the three Molex substitute options?

A: The primary distinction is contact finish specification. Molex 0417920521 and 0417920538 feature gold mating contact finish, matching the original TE Connectivity part. Molex 0026605128 utilizes tin mating contact finish. Contact finish thickness also varies across the three options. All three parts maintain identical core connector architecture and electrical performance.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: The substitute parts feature increased insulation height (0.394" versus 0.300") and longer contact posts (0.156" versus 0.125") compared to the original part. These dimensional differences may affect board layout spacing and mating connector clearances. Physical verification against specific PCB designs and mating connector specifications is necessary prior to production implementation.

Q: Do all substitute parts maintain the same regulatory compliance as the original part?

A: Yes. All three Molex substitute parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings identical to the original TE Connectivity part. Moisture sensitivity level remains at MSL 1 (Unlimited) across all options.

Q: Why is the TE Connectivity 4-644633-2 listed as obsolete?

A: The original part has been discontinued by TE Connectivity. Active substitute parts from Molex ensure continued availability and supply chain support for applications requiring this connector type and configuration.

Q: What is the number of positions loaded for each substitute part?

A: Molex 0026605128 has 9 positions loaded, while Molex 0417920521 and 0417920538 have all 12 positions loaded. The original TE Connectivity part has all 12 positions loaded. Position loading configuration should be verified against specific application requirements.

Q: Are there inventory considerations when selecting a substitute part?

A: Current inventory levels are: TE Connectivity 4-644633-2 (840 pcs), Molex 0026605128 (706 pcs), Molex 0417920521 (1019 pcs), and Molex 0417920538 (709 pcs). Molex 0417920521 offers the highest current stock availability.
