Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3-647075-6 is determined by alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 6
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Style: Board to Cable/Wire or Board to Board

Functional Compatibility Parameters:

• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• Voltage Rating: 250VAC (minimum requirement)
• Material Flammability Rating: UL94 V-0 or equivalent (minimum requirement)
• RoHS Compliance: Required for regulatory alignment

The Molex 1718563006 connector satisfies all mandatory matching parameters and functional compatibility requirements, establishing it as a direct substitute for the obsolete TE Connectivity part.

Engineering Selection Recommendations

The Molex 1718563006 is a direct functional substitute for the obsolete TE Connectivity 3-647075-6 based on the following engineering criteria:

Product Status Alignment: The Molex part maintains active product status, ensuring ongoing availability, technical support, and supply chain continuity compared to the obsolete TE Connectivity original.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 export classification. The Molex part carries ROHS3 Compliant certification, which supersedes the RoHS Compliant status of the original part, providing enhanced regulatory alignment for current manufacturing standards.

Electrical and Mechanical Compatibility: The substitute part matches all critical parameters including connector type, contact configuration, pitch, mounting method, and shrouding design. Contact length variations (post length difference of 0.043") remain within acceptable tolerance for standard through-hole PCB applications and do not compromise functional performance.

Contact Finish Consideration: The original part features gold-plated mating contacts while the substitute features tin-plated contacts. Both finishes provide adequate corrosion resistance and electrical conductivity for general-purpose and board-to-cable applications. The tin finish of the Molex part is standard for the KK254 series and is suitable for equivalent performance in non-critical signal applications.

Flammability Rating Variance: The original part carries UL94 V-0 rating while the substitute carries UL94 V-2 rating. For applications requiring UL94 V-0 compliance, this variance must be evaluated against specific application requirements and regulatory mandates.

Packaging and Availability: The Molex part is supplied in Tape & Reel (TR) packaging with 992 pieces in current inventory, supporting automated assembly processes and high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1718563006 be used as a direct replacement for the TE Connectivity 3-647075-6 in existing designs?

A: Yes, the Molex 1718563006 functions as a direct substitute for board-to-cable and general-purpose applications. The connector maintains identical pitch (0.100"), position count (6), mounting type (through-hole), and shrouding configuration. Minor dimensional variations in contact length do not affect standard PCB mounting or mating performance.

Q: What is the significance of the contact finish difference between gold and tin?

A: The original part uses gold plating on mating contacts, while the substitute uses tin plating. Both finishes provide adequate electrical conductivity and corrosion resistance for general-purpose applications. Gold plating offers superior corrosion resistance in high-humidity or corrosive environments, while tin plating is standard for cost-effective general-purpose connectors. Application environment and signal integrity requirements determine whether this difference is material.

Q: Does the UL94 V-2 rating of the Molex part affect its suitability as a substitute?

A: The original part carries UL94 V-0 flammability rating while the substitute carries UL94 V-2. For applications with specific UL94 V-0 requirements mandated by design standards or regulatory compliance, this difference must be evaluated. For general-purpose applications without explicit V-0 requirements, the V-2 rating is acceptable.

Q: Are there packaging differences between the original and substitute parts?

A: The original part packaging information is not specified in available data. The Molex substitute is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. This packaging format supports high-volume production and pick-and-place equipment integration.

Q: What is the operating temperature range compatibility?

A: The original part specifies -55°C to 105°C operating temperature. The Molex substitute does not provide explicit operating temperature specification in available data. For applications requiring confirmed temperature range performance, the original specification of -55°C to 105°C should be verified with the Molex technical documentation.

Q: Are both parts RoHS compliant?

A: Yes. The original part is RoHS Compliant. The Molex substitute is ROHS3 Compliant, which represents current RoHS directive compliance and supersedes earlier RoHS compliance levels. Both parts meet RoHS requirements for current manufacturing standards.

Q: What voltage rating applies to the Molex substitute?

A: The original part specifies 250VAC voltage rating. The Molex substitute does not provide explicit voltage rating specification in available data. For applications requiring confirmed voltage rating performance, the original specification of 250VAC should be verified with the Molex technical documentation or datasheet.
