TE Connectivity AMP Connectors 3-644617-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 3-644617-8 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features 8 positions with 0.156" (3.96mm) pitch spacing and is classified as a shrouded, single-wall header with male pin contacts. The part is actively manufactured and maintained in production status, supporting general purpose and industrial applications across temperature ranges of -55°C to 105°C.

Substitute parts are identified when equivalent rectangular connectors share critical electrical and mechanical parameters, including pitch spacing, number of positions, contact configuration, mounting style, and termination method. Identifying suitable alternatives ensures design flexibility and supply chain continuity for board-to-cable and board-to-board interconnection requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 3-644617-8 are identified based on strict equivalence of critical connector parameters. The substitution logic is based on the following key parameters that must align across parts:

Critical Matching Parameters:

• Pitch spacing: 0.156" (3.96mm)
• Number of positions: 8
• Number of rows: 1
• Connector type: Header
• Contact type: Male Pin
• Mounting style: Through Hole, Right Angle
• Termination method: Solder
• Shrouding configuration: Shrouded - 1 Wall
• Fastening type: Friction Lock
• Contact finish: Tin
• Material flammability rating: UL94 V-0
• Regulatory compliance: ROHS3 Compliant

The Molex 0026645080 connector meets these critical parameters and is classified as a direct substitute. Both connectors support board-to-cable and board-to-board interconnection styles with identical pitch and position configurations, enabling functional interchangeability in applications requiring 8-position, 0.156" spaced rectangular headers with right-angle through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 3-644617-8 and Molex 0026645080 connectors are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts is based on the following engineering considerations:

TE Connectivity 3-644617-8:

• Contact material: Copper Alloy
• Insulation material: Thermoplastic, Glass Filled
• Contact finish thickness - Mating: 150.0µin (3.81µm)
• Voltage rating: 600VAC specified
• Insulation height: 0.300" (7.62mm)
• Contact length - Post: 0.125" (3.18mm)

Molex 0026645080:

• Contact material: Brass
• Insulation material: Polyester
• Contact finish thickness - Mating: 60.0µin (1.52µm)
• Insulation height: 0.394" (10.00mm)
• Contact length - Post: 0.156" (3.96mm)

Both parts satisfy ROHS3 compliance requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings. The primary differences lie in contact material composition, insulation material selection, and physical dimensions. Selection should be based on specific application requirements regarding contact material performance, insulation material compatibility, and board layout constraints related to connector height and post length specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026645080 directly replace the TE Connectivity 3-644617-8 in existing designs?

A: Both connectors share identical pitch spacing (0.156"), position count (8), mounting style (through-hole right-angle), and termination method (solder). However, differences in contact post length (0.125" versus 0.156"), insulation height (0.300" versus 0.394"), and contact material (copper alloy versus brass) require verification against specific board layout and electrical performance requirements before substitution.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching pitch spacing, number of positions, number of rows, connector type, contact type, mounting configuration, termination method, shrouding style, fastening mechanism, contact finish, and flammability rating. Both parts meet these criteria for the 8-position, 0.156" pitch rectangular header category.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the TE Connectivity 3-644617-8 and Molex 0026645080 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain UL94 V-0 material flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the difference in contact material between these connectors?

A: The TE Connectivity part uses copper alloy contacts, while the Molex part uses brass contacts. Both materials are tin-finished for corrosion resistance. Contact material selection affects electrical conductivity, mechanical durability, and cost characteristics. Application-specific requirements should guide material selection.

Q: How do the insulation materials differ?

A: The TE Connectivity connector uses thermoplastic with glass filling, providing enhanced mechanical strength and thermal stability. The Molex connector uses polyester insulation. Both materials achieve UL94 V-0 flammability ratings. Insulation material selection impacts temperature performance, mechanical properties, and chemical resistance.

Q: Are there differences in physical dimensions that affect board layout?

A: Yes. The Molex connector has a greater insulation height (0.394" versus 0.300") and longer contact posts (0.156" versus 0.125"). These dimensional differences may impact PCB layout, clearance requirements, and mating depth specifications. Board design must accommodate these variations.

Q: What voltage and current ratings apply to these connectors?

A: The TE Connectivity 3-644617-8 specifies a 600VAC voltage rating. Current rating varies by wire gauge for both parts. The Molex part does not specify voltage or current ratings in the provided data. Application-specific electrical requirements should be verified against manufacturer datasheets.

Q: Can these connectors be used interchangeably in automotive applications?

A: The Molex 0026645080 lists automotive applications in its specification. The TE Connectivity 3-644617-8 is specified for general purpose and industrial applications. Automotive application suitability should be confirmed against specific design requirements and applicable automotive standards.
