Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1452668-3 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: TE Connectivity AMP Connectors
• Series: MCON
• Contact Type: Socket
• Termination Method: Crimp
• Contact Finish: Silver
• Contact Finish Thickness: 78.7µin (2.00µm)
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Criteria:

• Wire Gauge Range: Must accommodate the 18-20 AWG specification
• RoHS Compliance: Must meet or exceed ROHS3 Compliant status
• ECCN Classification: EAR99
• HTSUS Code: 8536.90.4000

The substitute part 7-1452665-3 shares the same manufacturer, series, contact type, termination method, contact finish, finish thickness, and MSL rating. However, the wire gauge specification differs (22-24 AWG versus 18-20 AWG), which represents a key parameter variance that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 7-1452665-3 is an active product offering from TE Connectivity AMP Connectors within the MCON series. This part maintains electrical and mechanical compatibility across all critical parameters including contact finish, finish thickness, termination method, and moisture sensitivity rating.

The primary variance between the main part and substitute is the wire gauge specification: 1452668-3 is rated for 18-20 AWG, while 7-1452665-3 is rated for 22-24 AWG. This difference reflects distinct contact geometries and current-carrying capacities designed for their respective wire gauge ranges.

The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain equivalent RoHS compliance and regulatory classifications (ECCN EAR99, HTSUS 8536.90.4000).

Selection between these parts must be based on the actual wire gauge requirements of the application. If the application circuit utilizes 18-20 AWG conductors, the original specification 1452668-3 remains the appropriate choice. If the application utilizes 22-24 AWG conductors, the substitute 7-1452665-3 is the suitable alternative.

Frequently Asked Questions (FAQ)

Q: Can 7-1452665-3 be used as a direct replacement for 1452668-3?

A: The parts share identical electrical and mechanical characteristics within the MCON series, including contact finish, finish thickness, and termination method. However, the wire gauge ratings differ. Direct substitution is only appropriate if the application circuit uses 22-24 AWG conductors instead of 18-20 AWG.

Q: What is the significance of the wire gauge difference between these parts?

A: Wire gauge determines the contact bore diameter and current-carrying capacity. The 1452668-3 socket contact is designed for 18-20 AWG wire, while the 7-1452665-3 is designed for 22-24 AWG wire. Using an incorrect wire gauge contact can result in poor electrical connection or mechanical damage.

Q: Why is 1452668-3 listed as obsolete?

A: The part is classified as obsolete, indicating it is no longer in active production. The substitute part 7-1452665-3 is actively manufactured and represents the current product offering from TE Connectivity AMP Connectors for similar applications within the MCON series.

Q: Are both parts RoHS compliant?

A: Yes. The main part 1452668-3 is ROHS3 Compliant, and the substitute 7-1452665-3 is RoHS Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the packaging difference between these parts?

A: The main part 1452668-3 packaging is not specified in the available data. The substitute part 7-1452665-3 is supplied in Cut Tape (CT) packaging format.

Q: Are the contact finish specifications identical?

A: Yes. Both parts feature silver contact finish with a thickness of 78.7µin (2.00µm), ensuring equivalent electrical conductivity and corrosion resistance characteristics.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
