Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1452671-3 is based on the following critical parameters that define functional and mechanical compatibility:

Primary Substitution Criteria:

• Manufacturer: TE Connectivity AMP Connectors
• Series: MCON
• Category: Rectangular Connectors
• Type: Stamped
• Pin or Socket: Socket
• Contact Termination: Crimp
• Contact Finish: Silver
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 7-1452671-3 maintains all core functional parameters within the MCON series. The wire gauge specification differs (16-18 AWG versus 15-17 AWG), representing a compatible range overlap suitable for applications requiring socket contacts in this connector family. The contact finish thickness remains within acceptable tolerances for silver-plated crimp sockets.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 7-1452671-3 is an active product offering from TE Connectivity AMP Connectors and maintains ROHS3 compliance and MSL 1 rating identical to the obsolete 1452671-3. Both parts are stamped silver-plated crimp socket contacts within the MCON rectangular connector series.

The primary distinction is the wire gauge specification: the substitute accommodates 16-18 AWG wire, compared to the original 15-17 AWG specification. This represents a one-gauge shift in the acceptable wire range. The contact finish thickness differential (80.0µin versus 78.7µin) falls within standard manufacturing tolerances for silver plating on crimp contacts.

Selection of 7-1452671-3 is appropriate for applications where the 16-18 AWG wire gauge range aligns with system requirements. The active product status ensures ongoing availability and supply chain support compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can 7-1452671-3 directly replace 1452671-3 in existing assemblies?

A: Both parts are socket contacts within the MCON series with identical termination type (crimp), finish (silver), and compliance ratings. The wire gauge difference (16-18 AWG versus 15-17 AWG) must be evaluated against the specific wire sizes used in the application. If the application uses wire within the 16-18 AWG range, direct substitution is supported by the common series, type, and electrical specifications.

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

A: Wire gauge determines the contact's crimp cavity dimensions and contact pressure characteristics. The 1452671-3 is specified for 15-17 AWG wire, while 7-1452671-3 is specified for 16-18 AWG wire. The one-gauge overlap (16-17 AWG) represents a compatible range where both parts could theoretically accommodate the wire size, though each part is optimized for its specified range.

Q: Are there compliance or environmental differences between these parts?

A: Both parts carry identical RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) ratings. No compliance or environmental performance differences exist between the two parts based on provided specifications.

Q: What is the packaging difference, and does it affect substitution?

A: The substitute part 7-1452671-3 is supplied in Cut Tape (CT) packaging, while the original part packaging is not specified. Packaging format affects handling, storage, and integration into manufacturing processes but does not alter the electrical or mechanical function of the contact itself.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects discontinuation of production. The active substitute 7-1452671-3 provides continued access to functionally equivalent socket contacts within the MCON series.
