TE Connectivity AMP Connectors 4-644633-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-644633-6 is a rectangular connector header designed for through-hole, right-angle mounting applications. This 16-position connector operates at 0.156" (3.96mm) pitch and is classified as an active product. The connector features shrouded design with friction lock fastening, making it suitable for general purpose and industrial applications requiring board-to-cable or board-to-board interconnection. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 4-644633-6 are identified based on strict equivalence of critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must match or be compatible:

Critical Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 16
• Number of Rows: 1
• Pitch - Mating: 0.156" (3.96mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Fastening Type: Friction Lock
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The Molex 0026605160 connector satisfies all critical matching parameters and is therefore classified as a direct substitute. Both connectors are active products with RoHS compliance and identical pitch, position count, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 4-644633-6 and Molex 0026605160 are active products with full RoHS compliance. The TE Connectivity part carries explicit voltage and temperature ratings (600VAC, -55°C to 105°C), while the Molex part does not specify these parameters in the provided data.

The primary difference between these connectors is the contact finish on the mating surface: the TE Connectivity part features gold plating (30.0µin thickness) while the Molex part features tin plating (60.0µin thickness). Additionally, the Molex connector has a slightly larger insulation height (0.394" versus 0.300") and longer contact post length (0.156" versus 0.125").

Selection between these parts should be based on application-specific requirements regarding contact finish, insulation height, and post length. Both connectors meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The TE Connectivity part is suitable for applications requiring documented voltage and temperature performance specifications. The Molex part is suitable for general purpose, automotive, medical, and telecommunications applications where the specified dimensional and finish characteristics are compatible with the end-use design.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026605160 be used as a direct replacement for the TE Connectivity 4-644633-6?

A: The Molex 0026605160 is electrically and mechanically compatible based on matching connector type, position count, pitch, mounting configuration, and shrouding. However, dimensional differences exist: the Molex connector has a larger insulation height (0.394" versus 0.300") and longer contact post (0.156" versus 0.125"). These differences must be evaluated against specific PCB layout and mating connector specifications before substitution.

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

A: The TE Connectivity part features gold-plated mating contacts (30.0µin), while the Molex part features tin-plated mating contacts (60.0µin). Gold plating provides superior corrosion resistance and lower contact resistance, making it suitable for applications requiring long-term reliability in harsh environments. Tin plating is suitable for general purpose applications with shorter service life requirements or lower cost constraints.

Q: Are both connectors RoHS compliant?

A: Yes. The TE Connectivity 4-644633-6 is RoHS Compliant, and the Molex 0026605160 is ROHS3 Compliant. Both meet current RoHS requirements for restricted substance elimination.

Q: What are the moisture sensitivity levels for these connectors?

A: Both connectors are rated MSL 1 (Unlimited), indicating they have unlimited shelf life and require no special moisture control during storage or handling.

Q: Does the Molex connector have published voltage and temperature ratings?

A: The provided data does not include voltage or temperature ratings for the Molex 0026605160. The TE Connectivity 4-644633-6 is rated for 600VAC and operating temperatures from -55°C to 105°C. Applications requiring documented performance specifications should reference the TE Connectivity part or obtain complete specifications from Molex.

Q: What applications are these connectors suitable for?

A: The TE Connectivity part is specified for general purpose and industrial applications. The Molex part is specified for automotive, general purpose, industrial, medical, and telecommunications applications. Both are suitable for board-to-cable and board-to-board interconnection in through-hole, right-angle configurations.
