Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TE Connectivity 644017-3 are identified based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 8
• Pitch - Mating: 0.156" (3.96mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Fastening Type: Friction Lock
• Material Flammability Rating: UL94 V-0

The Molex 0026482085 connector satisfies all mandatory matching parameters and is classified as an active product with current manufacturing support. This part maintains electrical and mechanical compatibility through identical pitch spacing, position count, shrouding configuration, and termination method. The substitute part is suitable for applications requiring direct functional replacement of the obsolete TE Connectivity component.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0026482085 connector is the identified substitute for the obsolete TE Connectivity 644017-3 based on functional and electrical equivalence. Selection of this substitute part is supported by the following factors:

Product Status: The TE Connectivity 644017-3 is classified as obsolete, while the Molex 0026482085 is an active product with current manufacturing availability. This status difference ensures long-term supply chain continuity and ongoing technical support for the substitute component.

Compliance Certifications: Both the original part and substitute meet UL94 V-0 material flammability requirements. The Molex substitute carries ROHS3 compliance, which represents current regulatory standards. Both parts are REACH Unaffected and classified under identical HTSUS and ECCN codes, confirming regulatory equivalence.

Electrical and Mechanical Compatibility: The substitute part maintains identical pitch spacing (0.156"), position count (8), contact type (male pin), mounting method (through hole), shrouding configuration (shrouded 1-wall), and termination method (solder). These parameters ensure direct functional replacement in existing circuit board layouts and mating connector applications.

Physical Dimensional Differences: The Molex substitute exhibits slightly larger contact lengths and insulation height compared to the original part. These dimensional variations are within acceptable tolerances for standard connector applications and do not preclude mechanical compatibility with standard mating connectors designed for 0.156" pitch headers.

Contact Finish Enhancement: The Molex substitute features gold-plated mating contacts compared to tin plating on the original part. Gold plating provides enhanced corrosion resistance and improved contact reliability, representing a performance enhancement for the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026482085 be used as a direct replacement for the TE Connectivity 644017-3 in existing designs?

A: Yes. The Molex 0026482085 maintains identical pitch spacing (0.156"), position count (8), contact type (male pin), mounting method (through hole), and shrouding configuration. These parameters ensure mechanical and electrical compatibility with existing mating connectors and circuit board layouts designed for the original TE Connectivity part.

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

A: The primary differences are contact finish material (gold versus tin), base contact material (brass versus copper alloy), insulation material composition (polyester versus thermoplastic glass-filled), and overall contact length dimensions. The Molex substitute features slightly longer contact lengths and greater insulation height. These differences do not affect functional compatibility for standard applications.

Q: Is the Molex 0026482085 compliant with current regulatory standards?

A: Yes. The Molex 0026482085 carries ROHS3 compliance, representing current regulatory requirements. Both the original and substitute parts are REACH Unaffected and share identical ECCN and HTSUS classifications, confirming regulatory equivalence.

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

A: The Breakaway feature on the Molex 0026482085 indicates that individual connector positions can be separated from the main header assembly. This feature provides design flexibility for applications requiring modular connector configurations. The breakaway capability does not affect compatibility with standard mating connectors or circuit board applications.

Q: Are there any temperature or voltage rating differences between the original and substitute parts?

A: The TE Connectivity original part specifies an operating temperature range of -55°C to 105°C and a voltage rating of 600VAC. The Molex substitute does not provide explicit temperature or voltage ratings in the available specifications. For applications with specific temperature or voltage requirements, these parameters should be confirmed with the component manufacturer.

Q: How does the gold plating on the Molex connector affect performance compared to the tin-plated original?

A: Gold plating provides enhanced corrosion resistance and improved contact reliability compared to tin plating. This represents a performance enhancement for the substitute component, particularly in applications exposed to moisture, temperature cycling, or corrosive environments.

Q: What packaging format is available for the Molex 0026482085?

A: The Molex 0026482085 is supplied in bulk packaging format with 1557 pieces currently in stock. The original TE Connectivity part does not specify packaging format in the available data.
