Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5-644766-4 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 24
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Material Flammability Rating: UL94 V-0

The Molex 0026481245 and Molex 0026482245 satisfy all mandatory matching parameters. Both components are manufactured by Molex, belong to the KK396 and 41671 series, and maintain active product status. These substitutes provide equivalent electrical and mechanical interface characteristics for board-to-board or cable applications with identical pitch spacing and position count.

Parameter Comparison

Engineering Selection Recommendations

Molex 0026481245 is suitable for applications where contact finish specifications do not mandate gold plating on mating surfaces. This part carries active product status, ROHS3 compliance, and maintains unlimited moisture sensitivity rating. The tin-plated mating contact finish provides corrosion resistance for general industrial applications.

Molex 0026482245 is suitable for applications requiring gold-plated mating contacts, matching the contact finish specification of the original TE Connectivity component. This part carries active product status, ROHS3 compliance, and maintains unlimited moisture sensitivity rating. The gold contact finish provides enhanced corrosion resistance and contact reliability for demanding industrial and telecommunications applications.

Both Molex substitutes provide superior product availability compared to the obsolete TE Connectivity 5-644766-4. Selection between the two Molex options depends on contact finish requirements: 0026481245 for tin-plated applications, 0026482245 for gold-plated applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026481245 or 0026482245 directly replace the TE Connectivity 5-644766-4 in existing designs?

A: Both Molex parts maintain identical pitch spacing (0.156"), position count (24), row configuration (1), mounting type (through hole), and fastening mechanism (friction lock). The primary design consideration is contact length variation: the Molex substitutes feature 0.450" mating contact length compared to 0.400" on the original part, resulting in 0.050" additional mating depth. PCB layout and mating connector depth must accommodate this dimensional difference.

Q: What is the difference between Molex 0026481245 and 0026482245?

A: The primary distinction is contact finish on the mating surface. The 0026481245 features tin plating (60.0µin thickness), while the 0026482245 features gold plating (20.0µin thickness). Both maintain identical electrical and mechanical interface characteristics. Selection depends on application requirements for contact corrosion resistance and conductivity.

Q: Are the substitute parts RoHS compliant?

A: Both Molex substitutes carry ROHS3 compliance certification. The original TE Connectivity part carries RoHS compliance. All three components are REACH Unaffected and classified under ECCN EAR99.

Q: What is the moisture sensitivity level for these connectors?

A: All three components—the original TE Connectivity 5-644766-4 and both Molex substitutes—carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.

Q: Are there packaging differences between the substitute parts?

A: The TE Connectivity 5-644766-4 packaging specification is not provided in the technical data. Both Molex substitutes are supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: What applications are these connectors suitable for?

A: The TE Connectivity 5-644766-4 is specified for general purpose and industrial applications. The Molex substitutes are specified for automotive, general purpose, industrial, medical, and telecommunications applications, providing broader application coverage.
