TE Connectivity AMP Connectors 1-640445-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-640445-8 is an active rectangular connector header designed for through-hole mounting applications. This shrouded, single-wall 18-position connector operates at 0.156" (3.96mm) pitch and supports board-to-cable/wire configurations in general purpose and industrial applications. The connector features male pin contacts with solder termination and friction lock fastening, rated for 600VAC operation across a temperature range of -55°C to 105°C.

Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design flexibility requires evaluation of equivalent components meeting the same electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1-640445-8 and Molex 0026481185 connectors maintain active product status and full compliance with ROHS3 regulations and UL94 V-0 flammability standards. Both components carry unlimited moisture sensitivity level (MSL 1) classification, indicating no special handling requirements during storage or assembly.

The connectors are functionally equivalent for applications requiring 18-position, 0.156" pitch rectangular headers with through-hole solder termination. Selection between these parts may be based on:

• Inventory availability and lead time considerations
• Preferred supplier relationships and procurement channels
• Specific insulation material requirements (thermoplastic glass-filled versus polyester)
• Contact material specifications (copper alloy versus brass)
• Mechanical dimension variations in contact length and insulation height

Both parts satisfy the core electrical and mechanical requirements for general purpose and industrial applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026481185 directly replace the TE Connectivity 1-640445-8 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.156"), position count (18), contact type (male pin), mounting method (through-hole solder), shrouding configuration (1-wall), and fastening mechanism (friction lock). The connectors are mechanically and electrically compatible for board-to-cable/wire applications.

Q: What are the physical dimension differences between these connectors?

A: The Molex 0026481185 features longer contact lengths and greater insulation height compared to the TE Connectivity 1-640445-8. Specifically, the Molex part has a mating contact length of 0.450" (11.43mm) versus 0.400" (10.16mm) for the TE part, and an insulation height of 0.500" (12.70mm) versus 0.425" (10.80mm). These dimensional variations may affect board layout and mating connector clearances.

Q: Are there material composition differences that affect performance?

A: The TE Connectivity part uses copper alloy contacts with thermoplastic glass-filled insulation, while the Molex part uses brass contacts with polyester insulation. Both materials meet UL94 V-0 flammability requirements and maintain equivalent electrical performance. Material selection should be evaluated based on specific application requirements for thermal management, mechanical durability, and chemical resistance.

Q: Do both connectors support the same voltage and temperature ratings?

A: The TE Connectivity 1-640445-8 specifies 600VAC operation across -55°C to 105°C. The Molex 0026481185 does not provide explicit voltage and temperature ratings in the available specifications. Voltage and temperature compatibility should be confirmed with the Molex datasheet before substitution in applications with specific electrical or thermal requirements.

Q: What is the significance of the "Breakaway" designation on the Molex connector?

A: The Molex 0026481185 includes a breakaway feature, allowing individual positions to be separated from the connector body. This feature provides design flexibility for applications requiring modular connector configurations. The TE Connectivity part does not include this breakaway capability.

Q: Are both connectors RoHS compliant?

A: Yes. Both the TE Connectivity 1-640445-8 and Molex 0026481185 are ROHS3 compliant, meeting the Restriction of Hazardous Substances directive requirements for lead-free and restricted substance elimination.

Q: What is the current rating for these connectors?

A: The TE Connectivity 1-640445-8 specifies current rating as "Varies by Wire Gauge," indicating that current capacity depends on the gauge of wire used in the mating cable assembly. The Molex 0026481185 does not provide an explicit current rating specification. Current capacity should be determined based on wire gauge and application requirements.
