Switchcraft 390 Circular Connector Adapter - Equivalent & Substitute Parts

Part Overview

The Switchcraft 390 is a circular connector adapter designed for 3-pin XLR male-to-male inline applications. This component functions as a gender changer and pin configuration converter within the Q-G® series standard connector line. The 390 features a push-pull detent lock fastening mechanism with shielded construction and nickel-finished zinc die-cast housing.

The 390 carries an obsolete product status. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and new assembly applications where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Switchcraft 390 is determined by the following critical parameters:

• XLR shell size on both adapter ends
• 3-position pin count on both ends
• Male-to-male pin gender configuration
• Free hanging inline mounting type
• Shielded construction
• Zinc die-cast housing with nickel finish
• Q-G® series classification
• ROHS3 compliance

The substitute part 390X maintains all these core parameters, establishing direct functional equivalence. Differences in product status (active vs. obsolete) and packaging configuration do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft 390X serves as the direct substitute for the obsolete Switchcraft 390. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and replacement applications.

The 390X is currently in active production with confirmed inventory availability (930 pcs), whereas the 390 is obsolete with limited remaining stock (1010 pcs). For applications requiring ongoing supply assurance, the 390X is the appropriate selection.

The fastening mechanism differs slightly between the two parts: the 390 specifies "Push-Pull, Detent Lock" while the 390X specifies "Push-Pull." This difference does not affect mechanical or electrical compatibility within the XLR 3-pin male-to-male adapter application space.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft 390X directly replace the Switchcraft 390 in existing assemblies?

A: Yes. Both components share identical XLR shell sizing, 3-position pin configuration, male-to-male gender, free hanging mounting style, shielded construction, and housing materials. The 390X is the active production equivalent.

Q: What is the difference between the fastening types listed for these parts?

A: The 390 lists "Push-Pull, Detent Lock" while the 390X lists "Push-Pull." Both provide secure mating and demating functionality within the Q-G® series standard. The specification difference does not impact functional compatibility.

Q: Are there packaging differences between the 390 and 390X?

A: Yes. The 390 is supplied in standard packaging, while the 390X is supplied in bulk packaging. This distinction affects logistics and inventory management but does not alter the component's electrical or mechanical properties.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the 390 and 390X are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: Why is the 390 listed as obsolete?

A: The 390 has been superseded by the 390X in Switchcraft's active product line. The 390X maintains all functional specifications while offering improved supply chain continuity.
