Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-647295-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 12
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Contact Shape: Square
• Insulation Color: Black
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute parts identified—Molex 1718560012 and Molex 1718561012—satisfy all mandatory matching parameters. Both are active-status rectangular connectors from the Molex KK254 series, providing direct functional equivalence for board-to-board and cable applications. The primary distinction between the two Molex substitutes lies in contact finish specifications on the mating surface, with 1718560012 featuring tin finish and 1718561012 featuring gold finish.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 4-647295-2 is classified as obsolete. Both Molex substitute parts (1718560012 and 1718561012) maintain active product status, ensuring ongoing availability, technical support, and manufacturing continuity.

Compliance and Certification: All three connectors are RoHS compliant and carry EAR99 export classification. The Molex substitutes hold ROHS3 compliance and REACH Unaffected status, providing enhanced regulatory alignment for current manufacturing standards. The TE Connectivity original part specifies UL94 V-0 flammability rating, while both Molex substitutes carry UL94 V-2 rating. This represents a difference in material flammability performance that must be evaluated against specific application requirements.

Contact Finish Selection: Molex 1718560012 features tin-plated mating contacts, matching the original TE Connectivity part's contact finish material. Molex 1718561012 provides gold-plated mating contacts, offering enhanced corrosion resistance and contact reliability in demanding environments. Selection between these two Molex options depends on application-specific requirements for contact durability and environmental exposure.

Dimensional Compatibility: Minor dimensional variations exist between the original and substitute parts. The Molex substitutes feature slightly longer mating contact length (0.293" versus 0.290") and reduced post length (0.092" versus 0.135"), resulting in overall contact length reduction from 0.550" to 0.510". Insulation height is reduced from 0.347" to 0.322". These dimensional differences require verification against specific PCB layout and mating connector specifications to ensure mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can Molex 1718560012 and Molex 1718561012 be used interchangeably with the TE Connectivity 4-647295-2?

A: Both Molex parts satisfy the core functional parameters required for substitution: 12-position, single-row header configuration with 0.100" (2.54mm) pitch, through-hole solder termination, shrouded design with friction lock fastening, and square contact geometry. However, dimensional variations in contact length and insulation height require verification against specific application constraints before interchangeability is confirmed.

Q: What is the primary difference between Molex 1718560012 and Molex 1718561012?

A: The primary distinction is the mating contact finish. Molex 1718560012 features tin-plated mating contacts with 60.0µin (1.52µm) thickness, while Molex 1718561012 features gold-plated mating contacts with 15.0µin (0.38µm) thickness. Gold plating provides superior corrosion resistance and contact reliability in high-reliability applications, whereas tin plating offers cost efficiency for general-purpose applications.

Q: Why does the TE Connectivity original part specify UL94 V-0 while the Molex substitutes specify UL94 V-2?

A: UL94 V-0 represents a higher flammability performance rating than UL94 V-2. This difference reflects variations in insulation material composition between the TE Connectivity PA4T nylon and the Molex PA nylon formulations. Applications requiring UL94 V-0 compliance must evaluate whether UL94 V-2 performance is acceptable for their specific safety and regulatory requirements.

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

A: The TE Connectivity 4-647295-2 packaging information is not specified in available documentation. Both Molex substitutes are supplied in bulk packaging. Packaging format should be confirmed with suppliers to ensure compatibility with assembly and procurement workflows.

Q: What are the implications of the dimensional differences in contact length?

A: The Molex substitutes feature mating contact length of 0.293" compared to the original 0.290", and reduced post length of 0.092" compared to the original 0.135". These variations affect overall connector stack height and PCB penetration depth. Verification against mating connector specifications and PCB layout requirements is necessary to ensure proper mechanical engagement and electrical continuity.

Q: Do the Molex substitutes support the same voltage and temperature ratings as the original TE Connectivity part?

A: The TE Connectivity original specifies 250VAC voltage rating and -55°C to 105°C operating temperature range. The Molex substitutes do not provide explicit voltage or temperature specifications in available documentation. Application-specific voltage and temperature requirements must be cross-referenced with detailed Molex technical specifications to confirm suitability.

Q: Are all three connectors RoHS compliant?

A: Yes. The TE Connectivity 4-647295-2 is RoHS Compliant. Both Molex substitutes (1718560012 and 1718561012) are ROHS3 Compliant, representing current RoHS directive compliance standards. Additionally, both Molex parts carry REACH Unaffected status, providing enhanced regulatory documentation for current manufacturing environments.
