Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 3-647648-9 and Molex 1718130009 connectors are active production parts with full regulatory compliance. Selection between these parts should be based on the following engineering considerations:

TE Connectivity 3-647648-9:

• Specified voltage rating of 600VAC provides explicit electrical performance documentation
• Specified operating temperature range of -55°C to 105°C defines thermal operating envelope
• UL94 V-0 flammability rating indicates superior flame resistance
• RoHS Compliant certification confirms hazardous substance restrictions
• Circular contact geometry provides standardized mating interface

Molex 1718130009:

• ROHS3 Compliant certification indicates current regulatory alignment
• Higher inventory availability (3287 pieces) supports supply chain continuity
• Square contact geometry offers alternative contact interface design
• Brass contact material provides alternative electrical conductivity characteristics
• Suitable for automotive, medical, and telecommunications applications per documented specifications

Both parts maintain identical pitch spacing (0.156"), position count (9), mounting methodology (through-hole solder), and shrouding configuration (1-wall). The primary differences are contact geometry (circular versus square), contact material composition (copper alloy versus brass), insulation height variance (0.545" versus 0.446"), and flammability rating classification (UL94 V-0 versus UL94 V-2).

Frequently Asked Questions (FAQ)

Q: Can the Molex 1718130009 directly replace the TE Connectivity 3-647648-9 in existing designs?

A: Both connectors share identical pitch spacing (0.156"), position count (9), mounting type (through-hole), and termination method (solder). However, the contact geometry differs (circular versus square), and the Molex part has a lower insulation height (0.446" versus 0.545"). Physical board layout and mating connector compatibility must be verified before substitution.

Q: What are the key electrical differences between these two parts?

A: The TE Connectivity part specifies a 600VAC voltage rating and -55°C to 105°C operating temperature range. The Molex part does not provide explicit voltage or temperature specifications in the available documentation. Applications requiring documented electrical performance parameters should reference the TE Connectivity part specifications.

Q: How do the contact materials affect connector performance?

A: The TE Connectivity part uses copper alloy contacts, while the Molex part uses brass contacts. Both materials are suitable for general purpose, industrial, and telecommunications applications. Contact material selection affects electrical conductivity, corrosion resistance, and cost characteristics. Application-specific requirements determine material suitability.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 3-647648-9 is RoHS Compliant. The Molex 1718130009 is ROHS3 Compliant. Both certifications confirm compliance with hazardous substance restrictions and are suitable for regulated applications.

Q: What is the significance of the UL94 flammability rating difference?

A: The TE Connectivity part carries a UL94 V-0 rating, indicating superior flame resistance and self-extinguishing properties. The Molex part carries a UL94 V-2 rating, indicating good flame resistance with limited dripping. Applications in high-temperature or flame-sensitive environments should prioritize the UL94 V-0 rated part.

Q: Do both connectors support the same mating interface?

A: Both connectors are shrouded, single-wall headers with 9 positions at 0.156" pitch and friction lock fastening. However, the contact shape differs (circular versus square). Mating connectors must be compatible with the specific contact geometry of the selected header.

Q: What packaging options are available?

A: The TE Connectivity 3-647648-9 packaging specification is not provided. The Molex 1718130009 is supplied in bulk packaging. Packaging requirements should be confirmed with the component supplier.

Q: Are both parts suitable for automotive applications?

A: The Molex 1718130009 is explicitly documented for automotive applications. The TE Connectivity 3-647648-9 is documented for general purpose and industrial applications. Automotive-specific design requirements should reference the Molex part specifications.
