TE Connectivity AMP Connectors 641938-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 641938-6 is an active rectangular connector header designed for through-hole mounting applications. This vertical 8-position connector operates at 0.156" (3.96mm) pitch and is configured for board-to-cable/wire connections with solder termination. The connector features shrouded single-wall design with friction lock fastening, suitable for general purpose and industrial applications. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate alternative component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by alignment of critical electrical and mechanical parameters. The primary criteria for equivalency include connector pitch, number of positions, number of rows, mounting type, termination method, shrouding configuration, and fastening mechanism. Both the main part (641938-6) and the identified substitute (0026482085) share the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 8
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

These aligned parameters establish functional compatibility for board-to-cable/wire connection applications. Differences in contact geometry, contact finish specifications, insulation materials, and dimensional tolerances are secondary considerations that do not prevent substitution in general purpose and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 641938-6 and Molex 0026482085 are active product status connectors with equivalent regulatory compliance. Both parts carry UL94 V-0 material flammability ratings and MSL 1 moisture sensitivity levels, indicating suitability for standard industrial storage and handling conditions without desiccant requirements.

The TE Connectivity 641938-6 provides specified operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC), making it suitable for applications requiring defined thermal and electrical performance parameters. The Molex 0026482085 offers broader application scope across automotive, medical, and telecommunications sectors, with all positions loaded versus the TE part's 7 loaded positions.

Both parts meet the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The TE Connectivity part maintains RoHS Compliant status, while the Molex part carries ROHS3 Compliant status, both satisfying current regulatory requirements.

Selection between these parts should be based on specific application requirements regarding contact finish (tin versus gold), contact geometry (circular versus square), insulation material properties (thermoplastic glass-filled versus polyester), and dimensional tolerances for mating interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026482085 directly replace the TE Connectivity 641938-6 in existing designs?

A: Both connectors share identical pitch (0.156"), position count (8), row configuration (1), mounting type (through hole), termination method (solder), shrouding (shrouded 1-wall), and fastening mechanism (friction lock). Substitution is mechanically and electrically compatible for general purpose and industrial applications. Dimensional differences in contact length and insulation height require verification against specific PCB layout and mating interface specifications.

Q: What are the key differences between these two connector headers?

A: Primary differences include contact finish (tin versus gold), contact shape (circular versus square), contact material (copper alloy versus brass), insulation material (thermoplastic glass-filled versus polyester), and overall dimensional envelope. The Molex part features all positions loaded compared to the TE part's 7 loaded positions. The TE part specifies operating temperature range and voltage rating; the Molex part does not provide these specifications.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 641938-6 is RoHS Compliant. The Molex 0026482085 is ROHS3 Compliant. Both satisfy current RoHS regulatory requirements for electronic component manufacturing and distribution.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These connectors do not require desiccant packaging or controlled humidity storage conditions during standard industrial handling and assembly operations.

Q: How do the contact dimensions differ between these parts?

A: The TE Connectivity 641938-6 provides 0.400" (10.16mm) mating contact length and 0.125" (3.18mm) post length. The Molex 0026482085 provides 0.450" (11.43mm) mating contact length and 0.172" (4.37mm) post length. These dimensional differences affect insertion depth and mating interface compatibility with corresponding receptacle connectors.

Q: What applications are these connectors suitable for?

A: The TE Connectivity 641938-6 is specified for general purpose and industrial applications. The Molex 0026482085 is specified for automotive, general purpose, industrial, medical, and telecommunications applications. Both are suitable for board-to-cable/wire connection configurations in standard industrial environments.
