Switchcraft 440Z Equivalent & Substitute Parts

Part Overview

The Switchcraft 440Z is a 6.35mm (0.250", 1/4") mono headphone phone plug connector with screw termination, designed for free-hanging in-line applications. This connector features shielded construction with internal interlock and accommodates 2 conductors and 2 contacts. The 440Z carries an obsolete product status, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Substitute Part Grouping Explanation

The Switchcraft 440X qualifies as a direct substitute for the 440Z based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector Type: Phone Plug (identical)
• Gender: Male (identical)
• Signal Lines: Mono (identical)
• Industry Recognized Mating Diameter: 6.35mm (0.250", 1/4") - Headphone (identical)
• Actual Diameter: 0.250" (6.35mm) (identical)
• Number of Positions/Contacts: 2 Conductors, 2 Contacts (identical)
• Internal Switch(s): Does Not Contain Switch (identical)
• Mounting Type: Free Hanging (In-Line) (identical)
• Termination: Screw (identical)
• Shielding: Shielded (identical)
• Features: Internal Interlock (identical)
• Mating Length/Depth: 1.218" (30.90mm) (identical)

The 440X maintains full compatibility with applications originally specified for the 440Z, with the primary distinction being product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft 440X is the appropriate selection for applications currently using or specifying the 440Z. The 440X maintains active product status with Switchcraft Inc., ensuring continued availability and supply chain stability. Both parts carry identical REACH and ECCN classifications, confirming regulatory equivalence. The 440X is RoHS3 compliant, providing enhanced environmental compliance for new designs and procurement cycles. Selection of the 440X eliminates obsolescence risk while preserving full electrical and mechanical compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the 440X directly replace the 440Z in existing applications?

A: Yes. The 440X and 440Z share identical electrical and mechanical specifications across all critical parameters including connector type, gender, signal configuration, mating diameter, contact count, mounting type, termination method, shielding, and physical dimensions. Direct substitution is valid without design modification.

Q: What is the primary advantage of transitioning from 440Z to 440X?

A: The 440Z is classified as obsolete, while the 440X maintains active product status. This transition ensures long-term component availability, reduces supply chain risk, and provides access to current manufacturing and quality assurance processes.

Q: Are there packaging differences between the 440Z and 440X?

A: The 440Z packaging is listed as unspecified, while the 440X is supplied in bulk packaging. Both parts include identical component sets: 1 connector, 1 handle, and 2 screws per unit.

Q: Do compliance certifications differ between these parts?

A: Both parts carry REACH Unaffected and EAR99 ECCN classifications. The 440X additionally carries RoHS3 compliance certification, providing enhanced environmental standards for new procurement.

Q: Are the physical dimensions identical?

A: Yes. Both the 440Z and 440X maintain a mating length/depth of 1.218" (30.90mm) and actual diameter of 0.250" (6.35mm), ensuring mechanical compatibility in all mounting and panel configurations.
