Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 4-647296-2 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for functional substitution:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Number of rows (1)
• Pitch spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 1 Wall)
• Termination method (Solder)
• Fastening type (Friction Lock)
• Contact shape (Square)

Acceptable Variation Parameters:

• Contact finish composition (Gold or Tin on mating surface)
• Contact material (Copper Alloy or Brass)
• Insulation material formulation (PA4T or PA)
• Contact length dimensions (within tolerance for mating compatibility)
• Insulation height (within tolerance for board spacing)

The Molex 1718560012 and Molex 1718561012 rectangular connectors meet all critical matching parameters and are classified as direct functional equivalents to the TE Connectivity 4-647296-2.

Engineering Selection Recommendations

Molex 1718561012 (Preferred Substitute)

The Molex 1718561012 is the primary recommended substitute for the obsolete TE Connectivity 4-647296-2. This part maintains active product status and provides the closest electrical and mechanical alignment. The mating contact finish is gold-plated, matching the original specification. Both parts carry RoHS compliance certifications (RoHS Compliant and ROHS3 Compliant respectively), ensuring regulatory alignment. The moisture sensitivity level remains at MSL 1 (Unlimited) for both parts. The contact length dimensions show minor variation (0.293" versus 0.290" mating length), which remains within acceptable tolerance for standard through-hole PCB applications. The insulation height difference of 0.025" (0.63mm) does not impact functional compatibility in typical board-to-cable configurations.

Molex 1718560012 (Alternative Substitute)

The Molex 1718560012 serves as an alternative substitute when the gold-plated mating contact finish of the 1718561012 is not required. This part features a tin-plated mating contact surface with increased finish thickness (60.0µin versus 15.0µin), providing enhanced corrosion resistance in certain environmental conditions. The part maintains active product status and full RoHS3 compliance. The mechanical dimensions and mounting characteristics are identical to the 1718561012. Selection of this part is appropriate for applications where tin plating is acceptable or preferred over gold plating.

Compliance Considerations

Both Molex substitutes carry ROHS3 Compliant status, which supersedes the RoHS Compliant designation of the original part. Both substitutes are REACH Unaffected, compared to the original part's Vendor Undefined REACH status. The material flammability rating differs between the original (UL94 V-0) and substitutes (UL94 V-2). Applications requiring the higher V-0 rating must evaluate this difference against specific design requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1718561012 be used as a direct replacement for the TE Connectivity 4-647296-2 in existing designs?

A: The Molex 1718561012 is mechanically and electrically compatible for standard through-hole PCB applications. The connector maintains the same 12-position, 0.100" pitch configuration, shrouded header design, and friction lock fastening. Minor dimensional variations in contact length and insulation height do not affect functional compatibility in typical board-to-cable interconnection scenarios. Applications with specific dimensional constraints or high-reliability requirements should verify the dimensional differences against design specifications.

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

A: The primary difference is the mating contact finish. The 1718561012 features gold plating (15.0µin thickness), matching the original TE Connectivity part. The 1718560012 features tin plating (60.0µin thickness). Both parts are functionally equivalent in terms of connector type, position count, pitch spacing, and mounting characteristics. Selection between these two depends on application requirements for contact finish material and corrosion resistance properties.

Q: Are there any compliance or regulatory differences between the original part and the substitutes?

A: The original TE Connectivity 4-647296-2 carries RoHS Compliant certification, while both Molex substitutes carry ROHS3 Compliant certification. ROHS3 represents an updated compliance standard and is acceptable for new designs. The material flammability rating differs: the original part is UL94 V-0, while the Molex substitutes are UL94 V-2. Applications requiring the higher V-0 rating must evaluate this difference. Both Molex substitutes are REACH Unaffected, compared to the original part's Vendor Undefined REACH status.

Q: What is the inventory status of these substitute parts?

A: The TE Connectivity 4-647296-2 is listed as obsolete with 1029 pieces in stock. The Molex 1718561012 is active with 736 pieces in stock. The Molex 1718560012 is active with 932 pieces in stock. Availability of the original part is limited due to obsolete status, making the active Molex substitutes the recommended options for ongoing production and design support.

Q: Are the contact length dimensions critical for substitution?

A: The contact length dimensions show minor variation between the original and substitute parts. The mating contact length differs by 0.003" (0.08mm), and the post length differs by 0.043" (1.09mm). These variations are within acceptable tolerance for standard through-hole solder termination and do not affect mating compatibility with standard 0.100" pitch receptacle connectors. Applications with specific dimensional constraints should verify these measurements against PCB design specifications.

Q: Can these connectors be used interchangeably in automotive and medical applications?

A: The Molex substitutes are specified for automotive, general purpose, medical, and telecommunications applications. The original TE Connectivity part is specified for general purpose applications only. Both Molex parts carry the same moisture sensitivity level (MSL 1 - Unlimited) and ECCN/HTSUS classifications as the original part. Applications in automotive or medical environments should verify that the Molex parts meet any additional application-specific requirements beyond the standard electrical and mechanical specifications.
