Engineering Selection Recommendations

Primary Substitutes:

The Molex 1718561012 is the preferred substitute for the TE Connectivity 4-647075-2. This part maintains the closest electrical and mechanical compatibility, including matching gold contact finish on the mating surface at equivalent thickness (15.0µin / 0.38µm). Both parts are RoHS compliant and carry unlimited moisture sensitivity ratings. The 1718561012 is currently in active production status, ensuring long-term availability and supply chain stability. Minor dimensional variations in contact post length (0.092" versus 0.135") and overall contact length (0.510" versus 0.550") are within acceptable engineering tolerances for through-hole solder termination applications.

Secondary Substitute:

The Molex 1718560012 provides functional equivalence with the primary distinction of tin plating on the mating contact surface (60.0µin / 1.52µm thickness). This part is also in active production and maintains all critical mechanical and electrical parameters. The increased tin plating thickness provides enhanced corrosion resistance in certain environmental conditions. Selection of this part is appropriate when tin-plated contacts are specified or preferred for the application.

Compliance Considerations:

Both substitute parts are ROHS3 compliant and carry REACH Unaffected status, matching the regulatory compliance profile of the original part. The material flammability rating difference (UL94 V-2 for substitutes versus UL94 V-0 for the original) represents a minor reduction in flame retardancy. Applications requiring UL94 V-0 certification should verify that V-2 rated substitutes meet specific design requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1718561012 be used as a direct replacement for the TE Connectivity 4-647075-2?

A: Yes. The 1718561012 maintains functional equivalence across all critical parameters including connector type, contact configuration, pitch spacing, position count, mounting method, and termination type. Minor dimensional variations in contact geometry fall within acceptable tolerances for through-hole solder applications.

Q: What is the difference between the two Molex substitute parts?

A: The primary difference is the contact finish on the mating surface. The 1718561012 features gold plating (15.0µin), matching the original TE part. The 1718560012 features tin plating (60.0µin), which provides enhanced corrosion resistance. Both parts are electrically and mechanically equivalent for standard applications.

Q: Does the flammability rating difference affect part selection?

A: The substitute parts carry UL94 V-2 ratings compared to the original part's UL94 V-0 rating. Both ratings meet standard safety requirements for rectangular connectors. Applications with specific UL94 V-0 requirements should verify that V-2 rated parts satisfy design specifications before implementation.

Q: Are the dimensional variations between parts significant?

A: Contact post length differs by 0.043" (0.092" versus 0.135"), and overall contact length differs by 0.040" (0.510" versus 0.550"). These variations are within acceptable tolerances for through-hole solder termination and do not affect mating interface compatibility. PCB layout and clearance verification is recommended during design transition.

Q: What is the availability status of substitute parts?

A: Both Molex substitute parts (1718560012 and 1718561012) are in active production status with current inventory availability. The original TE Connectivity part is obsolete, making these substitutes the recommended long-term solution for new designs and ongoing production support.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both Molex parts carry ROHS3 compliance certification and REACH Unaffected status, matching the regulatory compliance profile of the original TE Connectivity part.

Q: Which substitute part should be selected for new designs?

A: The Molex 1718561012 is recommended for new designs due to matching gold contact finish specifications and active production status. The 1718560012 is an acceptable alternative when tin-plated contacts are preferred or specified.
