Key Parameters

Substitute Part Grouping Explanation

Substitution for the Switchcraft 425 is determined by strict equivalence across the following critical parameters:

• Mating Diameter: 6.35mm (0.250", 1/4") - determines physical compatibility with mating receptacles
• Connector Type: Phone Plug - defines the connector family and interface standard
• Gender: Male - ensures correct mating orientation
• Number of Positions/Contacts: 2 Conductors, 2 Contacts - establishes signal path configuration
• Termination Type: Screw - specifies wire attachment method
• Mounting Type: Free Hanging (In-Line) - defines installation configuration
• Shielding: Shielded - ensures electromagnetic interference protection
• Contact Material - Plating: Tin - determines electrical and corrosion resistance properties
• Body Material: Copper Alloy - establishes mechanical and electrical characteristics
• Housing Material: Thermoplastic - defines structural and environmental resistance

The substitute part 425Z from Switchcraft Inc. meets all critical parameter requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft 425Z serves as a direct equivalent substitute for the obsolete Switchcraft 425 connector. Both parts are manufactured by Switchcraft Inc. and share identical specifications across all critical electrical and mechanical parameters that govern connector compatibility and performance.

The 425Z maintains ROHS3 compliance status consistent with the original 425 specification, ensuring regulatory alignment for applications requiring environmental compliance documentation. Current inventory availability of 882 units for the 425Z provides supply continuity for systems requiring this connector type.

Selection of the 425Z as a substitute is based on complete parameter equivalence and manufacturer continuity, eliminating compatibility risk in applications where the original 425 connector is specified.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft 425Z be used as a direct replacement for the Switchcraft 425?

A: Yes. The 425Z is a direct equivalent substitute. Both connectors share identical specifications for mating diameter (6.35mm), connector type (phone plug), gender (male), contact configuration (2 conductors, 2 contacts), termination method (screw), mounting type (free hanging in-line), shielding, contact plating (tin), body material (copper alloy), and housing material (thermoplastic).

Q: What determines compatibility between the 425 and 425Z?

A: Compatibility is established through equivalence of the following parameters: 6.35mm mating diameter, male gender, 2-contact configuration, screw termination, shielded design, and identical material specifications. These parameters ensure mechanical fit and electrical performance in the mating receptacle.

Q: Are there any differences in RoHS compliance between the 425 and 425Z?

A: The Switchcraft 425 is specified as ROHS3 compliant. The 425Z maintains equivalent compliance status, ensuring both parts meet the same environmental and regulatory requirements.

Q: What is the mating length specification for the 425Z?

A: The mating length for the 425 is 1.200" (30.50mm). The 425Z maintains this specification for dimensional compatibility with mating receptacles.

Q: Can these connectors be used interchangeably in audio and headphone applications?

A: Yes. Both the 425 and 425Z are designed for 6.35mm (1/4") headphone and audio applications. The identical connector type, contact configuration, and shielding specifications ensure functional equivalence in these applications.
