Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 111770-4 carries Obsolete status, indicating discontinued manufacturing and limited availability. The CNC Tech 3040-20-00 maintains Active product status with 25,901 pieces in current inventory, providing assured supply continuity for new designs and ongoing production requirements.

Compliance and Certification: The CNC Tech 3040-20-00 is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement. The original TE Connectivity 111770-4 is RoHS non-compliant, reflecting its legacy design status. Both components share identical ECCN classification (EAR99) and equivalent HTSUS coding within the rectangular connector category.

Contact Finish Specification: The TE Connectivity 111770-4 features tin contact finish at 100.0µin (2.54µm) thickness. The CNC Tech 3040-20-00 provides gold contact finish with flash thickness, offering enhanced corrosion resistance and contact reliability characteristics suitable for long-term deployment.

Mechanical and Electrical Equivalence: Both connectors maintain identical pitch specifications, row configuration, and IDC termination methodology, ensuring direct mechanical and electrical compatibility within existing PCB layouts and ribbon cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the CNC Tech 3040-20-00 directly replace the TE Connectivity 111770-4 in existing designs?

A: Yes. Both connectors share identical pitch specifications (0.050" cable pitch, 0.100" board-side pitch), row configuration (2 rows), position count (20), and IDC termination methodology. Through Hole mounting and Feed Through features are equivalent, enabling direct substitution without PCB layout modification.

Q: What are the key differences between these two connectors?

A: Primary differences include product status (Obsolete versus Active), RoHS compliance (non-compliant versus ROHS3 Compliant), contact finish material (tin versus gold), and current inventory availability. Electrical and mechanical specifications remain equivalent.

Q: Does the gold contact finish of the 3040-20-00 affect compatibility?

A: No. Contact finish material does not affect mechanical or electrical compatibility. Gold finish provides enhanced corrosion resistance compared to tin finish, representing an improvement in long-term reliability characteristics.

Q: Are there packaging differences between these connectors?

A: The TE Connectivity 111770-4 packaging specification is not provided. The CNC Tech 3040-20-00 is supplied in Tray packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: What wire gauge compatibility exists for the 3040-20-00?

A: Wire gauge specifications for the CNC Tech 3040-20-00 are not provided in the available documentation. The TE Connectivity 111770-4 supports 28 AWG stranded or 26-30 AWG solid wire gauges. Consult CNC Tech technical documentation for specific wire gauge compatibility of the 3040-20-00.

Q: Are both connectors suitable for new product designs?

A: The CNC Tech 3040-20-00 is recommended for new designs due to Active product status, ROHS3 compliance, and assured supply availability. The TE Connectivity 111770-4 is Obsolete and should not be specified for new development.
