TE Connectivity AMP Connectors 4-644627-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-644627-4 is an active rectangular connector header designed for through-hole mounting applications. This shrouded, single-wall 14-position connector operates at 0.156" (3.96mm) pitch and is configured for board-to-cable/wire connections with solder termination and friction lock fastening. The connector is manufactured from copper alloy contacts with gold mating finish and thermoplastic glass-filled insulation, rated for -55°C to 105°C operation and 600VAC voltage applications. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory requirements necessitate alternative manufacturer selection.

• Number of Positions: 14
• Pitch - Mating: 0.156" (3.96mm)
• Number of Rows: 1
• Mounting Type: Through Hole
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Fastening Type: Friction Lock
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: Both parts meet RoHS requirements
• REACH Status: Both parts are REACH Unaffected

Both connectors are classified as active products with current manufacturing status, ensuring availability and ongoing technical support. The substitute part operates within the same general application categories of industrial, general purpose, and telecommunications use.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 4-644627-4 and Molex 0026604140 are active products with current manufacturing status, ensuring continued availability and technical support. Both connectors meet UL94 V-0 flammability requirements and are RoHS compliant, satisfying regulatory requirements for industrial and general-purpose applications.

The primary distinction between these parts is the mating contact finish: the TE Connectivity part features gold plating (30.0µin thickness) on mating contacts, while the Molex substitute features tin plating (60.0µin thickness). This difference affects contact resistance characteristics and corrosion resistance properties. The TE Connectivity part is suitable for applications requiring enhanced corrosion resistance and lower contact resistance, while the Molex part is suitable for general-purpose industrial applications where tin plating provides adequate performance.

Minor dimensional variations exist in contact post length (0.125" versus 0.140") and overall contact length (0.700" versus 0.720"), which may affect board layout and mating depth considerations in space-constrained applications.

Both parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly. Both maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026604140 be used as a direct replacement for the TE Connectivity 4-644627-4?

A: The Molex 0026604140 is mechanically and electrically compatible for applications where the contact finish difference does not impact performance. Both connectors share identical pitch (0.156"), position count (14), mounting type (through-hole), and fastening mechanism (friction lock). The primary consideration is the mating contact finish: gold versus tin. Applications requiring enhanced corrosion resistance or lower contact resistance should retain the TE Connectivity part with gold plating.

Q: What is the significance of the contact finish difference between these parts?

A: The TE Connectivity 4-644627-4 features gold-plated mating contacts (30.0µin thickness), which provide superior corrosion resistance and lower contact resistance. The Molex 0026604140 features tin-plated mating contacts (60.0µin thickness), which is suitable for general-purpose industrial applications. Gold plating is typically specified for applications with stringent reliability requirements or exposure to corrosive environments.

Q: Are there dimensional differences that affect PCB layout?

A: Minor dimensional variations exist. The contact post length differs by 0.015" (0.125" versus 0.140"), and overall contact length differs by 0.020" (0.700" versus 0.720"). These variations may affect mating depth and board layout in space-constrained designs. Verify PCB footprint compatibility before substitution.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts are UL94 V-0 rated for flammability and meet RoHS compliance requirements. The TE Connectivity part is RoHS Compliant, while the Molex part is ROHS3 Compliant. Both are REACH Unaffected and carry EAR99 export classification. Both maintain Moisture Sensitivity Level 1 (Unlimited), requiring no special moisture handling.

Q: What are the application differences between these connectors?

A: The TE Connectivity 4-644627-4 is specified for general purpose and industrial applications. The Molex 0026604140 is specified for automotive, general purpose, industrial, medical, and telecommunications applications. The broader application range for the Molex part reflects its suitability across multiple industry sectors.

Q: How do the insulation materials differ?

A: The TE Connectivity part uses thermoplastic glass-filled insulation, while the Molex part uses polyester glass-filled insulation. Both materials provide UL94 V-0 flammability rating and support the same operating temperature range and moisture sensitivity classification.

Q: What inventory considerations should be evaluated?

A: The TE Connectivity 4-644627-4 has 772 pieces in stock, while the Molex 0026604140 has 10,914 pieces in stock. The significantly higher inventory level for the Molex part may provide supply chain advantages for high-volume production requirements or extended lead time mitigation.
