Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 4-644611-4 and Molex 0026604140 are active products with equivalent electrical and mechanical specifications for rectangular connector header applications. Selection between these parts is based on the following engineering considerations:

TE Connectivity 4-644611-4:

• RoHS Compliant status
• Thermoplastic, glass-filled insulation material
• Higher contact finish thickness on mating surface (150.0µin)
• Shorter post contact length (0.125")
• Current inventory: 700 pieces

Molex 0026604140:

• ROHS3 Compliant status (enhanced regulatory compliance)
• Polyester, glass-filled insulation material
• Lower contact finish thickness on mating surface (60.0µin)
• Longer post contact length (0.140")
• Current inventory: 10,914 pieces
• Broader application range: Automotive, General Purpose, Industrial, Medical, Telecommunications

Both parts meet UL94 V-0 flammability requirements, operate across -55°C to 105°C temperature range, and feature identical pitch, position count, and mounting configuration. The Molex substitute provides enhanced availability and extended application certification for medical and telecommunications sectors. Contact finish thickness and post length variations are within acceptable tolerances for standard through-hole solder termination applications.

Frequently Asked Questions (FAQ)

Q: What determines if the Molex 0026604140 can substitute for the TE Connectivity 4-644611-4?
