• Insulation Material: Polyamide or Nylon-based
• Insulation Color: Black

Secondary Compatibility Parameters:

• Contact Length - Mating: Within tolerance range (7.37mm reference)
• Contact Length - Post: Within tolerance range (3.43mm reference)
• Overall Contact Length: Within tolerance range (13.97mm reference)
• Insulation Height: Within tolerance range (8.81mm reference)
• Contact Finish: Tin or Gold plating acceptable
• Contact Material: Copper Alloy or Brass acceptable
• Operating Temperature: Minimum -55°C to 105°C coverage
• Voltage Rating: Minimum 250VAC

The substitute parts identified (Molex 1718560012 and 1718561012) satisfy all primary matching criteria and maintain compatibility within secondary parameter tolerances.

Parameter Comparison

Engineering Selection Recommendations

Molex 1718560012 Selection Criteria:

The Molex 1718560012 is an active product with ROHS3 compliance and MSL 1 rating. This part maintains dimensional compatibility within acceptable tolerances for the mating interface. The tin-plated contact finish on both mating and post surfaces provides equivalent electrical performance to the original TE Connectivity part. The brass contact material and polyamide insulation ensure functional equivalence. The UL94 V-2 flammability rating is lower than the original V-0 rating; applications requiring V-0 certification must not use this substitute.

Molex 1718561012 Selection Criteria:

The Molex 1718561012 is an active product with ROHS3 compliance and MSL 1 rating. This part offers enhanced contact reliability through gold plating on the mating surface (15.0µin thickness), providing superior corrosion resistance compared to tin-plated alternatives. The gold-plated mating surface is compatible with standard tin-plated receptacles. Like the 1718560012, the UL94 V-2 flammability rating is lower than the original V-0 rating; applications requiring V-0 certification must not use this substitute.

Compliance Considerations:

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original TE Connectivity part carries RoHS Compliant status (non-ROHS3 designation), indicating it predates ROHS3 implementation. Both substitutes provide equivalent or superior compliance posture for new designs and ongoing production.

Dimensional Tolerance Notes:

The substitute parts exhibit minor dimensional variations in contact post length (0.092" versus 0.135") and overall contact length (0.510" versus 0.550"). These variations remain within standard connector tolerance ranges and do not affect mating compatibility or electrical performance in standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can Molex 1718560012 and 1718561012 be used interchangeably with TE Connectivity 4-647047-2?

A: Both Molex parts satisfy the primary matching criteria for connector type, contact configuration, pitch spacing, mounting method, and termination. The parts are mechanically and electrically compatible for standard board-to-cable applications. The primary distinction is the contact finish: 1718560012 uses tin plating, while 1718561012 uses gold plating on the mating surface. Selection between these two depends on application-specific corrosion resistance requirements.

Q: What is the significance of the UL94 V-0 versus UL94 V-2 flammability rating difference?

A: The original TE Connectivity 4-647047-2 carries a UL94 V-0 rating, indicating superior flame retardancy. The Molex substitutes carry UL94 V-2 ratings. Applications subject to flammability certification requirements (aerospace, medical devices, high-temperature environments) must verify that UL94 V-2 compliance satisfies regulatory or customer specifications. Applications without specific flammability requirements are unaffected by this difference.

Q: Are there dimensional differences that affect PCB layout or mating compatibility?

A: Minor dimensional variations exist in contact post length and overall contact length. The TE Connectivity part specifies 0.135" post length and 0.550" overall contact length, while Molex parts specify 0.092" post length and 0.510" overall contact length. These variations remain within standard connector manufacturing tolerances and do not affect mating with standard 0.100" pitch receptacles or through-hole PCB mounting. Existing PCB designs require no modification.

Q: What is the difference between tin-plated (1718560012) and gold-plated (1718561012) contact finishes?

A: Tin plating provides standard electrical conductivity and corrosion resistance suitable for general-purpose applications. Gold plating (15.0µin thickness on mating surface) provides enhanced corrosion resistance and is preferred for applications subject to high humidity, salt spray exposure, or extended storage periods. Both finishes are compatible with standard tin-plated receptacles. Selection depends on environmental exposure and reliability requirements.

Q: Is the brass contact material equivalent to the copper alloy material in the original part?

A: Brass and copper alloy both provide acceptable electrical conductivity and mechanical properties for connector applications. Brass is a copper-tin alloy that offers equivalent performance characteristics. The contact material difference does not affect electrical or mechanical compatibility in standard applications.

Q: What does MSL 1 (Unlimited) moisture sensitivity level mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both the original TE Connectivity part and Molex substitutes carry MSL 1 ratings, eliminating moisture-related handling constraints.

Q: Are both Molex parts currently available for procurement?

A: Both Molex 1718560012 and 1718561012 are listed as active products. The original TE Connectivity 4-647047-2 is obsolete. Molex parts are suitable for new designs and ongoing production requirements where the original part is no longer available.
