Parameter Comparison

Engineering Selection Recommendations

The Molex 0022231045 connector is a direct functional equivalent to the TE Connectivity 3-647075-4. Selection of the Molex substitute is supported by the following engineering factors:

Product Status Consideration: The TE Connectivity 3-647075-4 is classified as obsolete, while the Molex 0022231045 maintains active product status. This distinction ensures continued manufacturing availability, supply chain reliability, and technical support for the substitute component.

Compliance and Certification Alignment: Both connectors maintain identical material flammability ratings (UL94 V-0), RoHS compliance status, and REACH compliance status. The Molex part achieves ROHS3 compliance, representing current regulatory standards. Both components are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Electrical and Mechanical Compatibility: The connectors share identical pitch spacing (0.100" / 2.54mm), position count (4), row configuration (1), contact geometry (square male pins), and termination method (solder). Contact finish specifications (gold mating surface, tin post finish) are identical. Minor variations in contact length dimensions and insulation height fall within acceptable tolerance ranges for through-hole connector applications and do not affect functional interchangeability.

Contact Material Consideration: The TE Connectivity part utilizes copper alloy contacts, while the Molex substitute employs brass contacts. Both materials provide equivalent electrical conductivity and corrosion resistance characteristics suitable for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022231045 be used as a direct replacement for the TE Connectivity 3-647075-4?

A: Yes. The Molex 0022231045 is functionally equivalent to the TE Connectivity 3-647075-4. Both connectors share identical pitch spacing (0.100" / 2.54mm), position count (4), contact configuration (male pins), mounting method (through-hole solder), and shrouding design (1-wall shrouded). The connectors are mechanically and electrically interchangeable for board-to-cable and board-to-board applications.

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

A: The primary differences are product status and contact material. The TE Connectivity part is obsolete, while the Molex part is active. The TE Connectivity connector uses copper alloy contacts, while the Molex connector uses brass contacts. Contact length dimensions vary slightly (TE: 0.290" mating / 0.135" post; Molex: 0.295" mating / 0.140" post), and insulation height differs marginally (TE: 0.347"; Molex: 0.322"). These variations do not affect functional compatibility.

Q: Are there any compliance or regulatory differences?

A: Both connectors maintain UL94 V-0 material flammability ratings and REACH unaffected status. The Molex part achieves ROHS3 compliance, while the TE Connectivity part is RoHS compliant. Both components are classified as Moisture Sensitivity Level 1 (Unlimited), requiring no special handling during storage or assembly.

Q: What is the packaging difference between these parts?

A: The TE Connectivity 3-647075-4 packaging information is not specified in the available data. The Molex 0022231045 is supplied in tube packaging. Packaging format does not affect connector functionality or interchangeability.

Q: Are the contact finish specifications compatible?

A: Yes. Both connectors feature gold-plated mating surfaces and tin-plated posts. The Molex part specifies a contact finish thickness of 20.0µin (0.51µm) on the mating surface and 100.0µin (2.54µm) on the post, compared to the TE Connectivity part's 15.0µin (0.38µm) mating finish. These specifications ensure equivalent electrical performance and corrosion resistance.

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

A: The TE Connectivity 3-647075-4 is designated for general-purpose applications. The Molex 0022231045 is rated for automotive, general-purpose, medical, and telecommunications applications. Application suitability depends on specific system requirements and design specifications beyond connector specifications alone.

Q: What is the operating temperature range for these connectors?

A: The TE Connectivity 3-647075-4 operates across -55°C to 105°C. Operating temperature specification for the Molex 0022231045 is not provided in the available data. Both connectors are suitable for standard industrial and commercial temperature environments.

Q: Why should I consider the Molex substitute if the TE Connectivity part is available in inventory?

A: The TE Connectivity 3-647075-4 is classified as obsolete product. While inventory may be available, obsolete status indicates discontinued manufacturing and limited long-term supply assurance. The Molex 0022231045 maintains active product status, ensuring ongoing availability, manufacturing support, and supply chain continuity for future production requirements and design revisions.
