Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The Molex 0022231045 is the primary substitute for the TE Connectivity AMP 3-647047-4. The Molex part carries active product status, ensuring ongoing availability and supply chain support. Both connectors meet identical regulatory requirements including ROHS3 compliance, REACH unaffected status, and UL94 V-0 flammability rating.

Compliance and Certification Alignment:

Both the original TE Connectivity AMP 3-647047-4 and the Molex 0022231045 substitute maintain equivalent environmental and regulatory certifications. Moisture sensitivity level 1 (unlimited) applies to both parts, indicating no special handling requirements during storage or assembly.

Contact Finish Consideration:

The Molex 0022231045 features gold-plated mating contacts (20.0µin thickness) compared to the tin finish on the original part. Gold plating provides enhanced corrosion resistance and contact reliability in applications subject to environmental exposure or extended storage intervals.

Mechanical Compatibility:

Contact length specifications differ marginally between the two parts. The Molex 0022231045 mating contact length is 0.295" (7.49mm) versus 0.290" (7.37mm) on the original, and post contact length is 0.140" (3.56mm) versus 0.135" (3.43mm). These dimensional variations remain within acceptable tolerance ranges for standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022231045 directly replace the TE Connectivity AMP 3-647047-4 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100" / 2.54mm), position count (4), row configuration (1), contact type (male pin), and mounting method (through-hole solder). The mating interface is fully compatible.

Q: What is the significance of the different contact finish materials?

A: The original TE Connectivity AMP 3-647047-4 uses tin-plated contacts, while the Molex 0022231045 uses gold-plated mating contacts. Gold plating enhances corrosion resistance and contact durability, particularly in applications with extended shelf life or exposure to moisture or corrosive environments. Both finishes are suitable for general-purpose applications.

Q: Are there differences in insulation material between these connectors?

A: Both connectors use polyamide (nylon) insulation materials. The TE Connectivity AMP 3-647047-4 specifies PA46 (nylon 4/6), while the Molex 0022231045 specifies PA (nylon). Both materials meet UL94 V-0 flammability requirements and provide equivalent electrical insulation performance.

Q: Does the Molex 0022231045 include a fastening mechanism?

A: Yes. The Molex 0022231045 includes friction lock fastening, whereas the original TE Connectivity AMP 3-647047-4 does not specify a fastening type. Friction lock provides positive retention of mated connectors without requiring additional hardware.

Q: What is the packaging format for the Molex 0022231045?

A: The Molex 0022231045 is supplied in tube packaging. The original TE Connectivity AMP 3-647047-4 packaging format is not specified in available documentation.

Q: Are both connectors RoHS compliant?

A: Yes. Both the TE Connectivity AMP 3-647047-4 and Molex 0022231045 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: What is the operating temperature range for the Molex substitute?

A: The operating temperature range for the Molex 0022231045 is not specified in available documentation. The original TE Connectivity AMP 3-647047-4 operates across -55°C to 105°C. Consult Molex technical documentation for specific thermal operating limits of the 0022231045.
