Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3-644614-8 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 8
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Fastening Type: Friction Lock
• Contact Length - Mating: 0.450" (11.43mm)
• Contact Shape: Square
• Contact Finish - Mating: Tin
• Material Flammability Rating: UL94 V-0

The Molex 0026645080 satisfies all mandatory matching parameters and qualifies as a direct functional equivalent. This substitute maintains electrical and mechanical compatibility while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0026645080 rectangular connector header is a direct functional substitute for the obsolete TE Connectivity 3-644614-8. Both components maintain identical electrical and mechanical specifications across all critical mating parameters, including pitch, position count, contact geometry, and termination method.

Compliance and Certification Alignment: Both parts achieve ROHS3 compliance and UL94 V-0 flammability rating, ensuring regulatory equivalence for industrial and general purpose applications. Both components carry MSL 1 (Unlimited) moisture sensitivity classification, indicating identical handling and storage requirements.

Supply Chain Considerations: The Molex substitute carries active product status with significantly higher inventory availability (12,445 units versus 1,064 units), providing improved long-term supply security. The TE Connectivity original part, classified as obsolete, presents ongoing procurement risk for future production requirements.

Physical Dimensional Variations: The Molex substitute exhibits minor dimensional differences in contact post length (0.156" versus 0.125") and insulation height (0.394" versus 0.300"). These variations do not affect mating compatibility or electrical performance in standard board-to-cable and board-to-board applications. Contact material composition differs (brass versus copper alloy) and contact finish thickness is reduced (60.0µin versus 150.0µin), both within acceptable parameters for the specified application class.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026645080 directly replace the TE Connectivity 3-644614-8 in existing designs?

A: Yes. The Molex substitute maintains identical pitch spacing (0.156"), position count (8), contact geometry (square male pins), mounting configuration (through-hole right-angle), and termination method (solder). Mating contact length is identical at 0.450" (11.43mm). Both components feature shrouded 1-wall construction with friction lock fastening.

Q: What are the differences in contact post dimensions?

A: The TE Connectivity original features a 0.125" (3.18mm) contact post length, while the Molex substitute provides 0.156" (3.96mm) post length. This difference does not affect mating compatibility with standard cable connectors or receptacle headers designed for 0.156" pitch spacing.

Q: How do the insulation materials differ between these parts?

A: The TE Connectivity part uses thermoplastic glass-filled insulation material, while the Molex substitute uses polyester insulation. Both materials achieve UL94 V-0 flammability rating and support the specified operating temperature range for general purpose and industrial applications.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, carry UL94 V-0 flammability certification, and maintain MSL 1 (Unlimited) moisture sensitivity classification. Both are REACH unaffected and classified under ECCN EAR99.

Q: What is the significance of the contact finish thickness difference?

A: The TE Connectivity original specifies 150.0µin (3.81µm) tin plating on mating contacts, while the Molex substitute provides 60.0µin (1.52µm) tin plating. Both thicknesses provide adequate corrosion protection and electrical conductivity for the specified application class and operating environment.

Q: Does the Molex substitute support the same voltage and temperature ratings?

A: The TE Connectivity original specifies 600VAC voltage rating and -55°C to 105°C operating temperature range. The Molex substitute does not provide published voltage and temperature specifications in the available data. For applications requiring explicit voltage or temperature ratings, contact the manufacturer for detailed specifications.

Q: What packaging format is available for the Molex substitute?

A: The Molex 0026645080 is supplied in bulk packaging format, compared to the TE Connectivity original which does not specify packaging type. Bulk packaging is standard for connector headers in industrial and general purpose applications.
