D3FBAU Equivalent & Substitute Parts

Part Overview

The D3FBAU is a 3-position circular connector plug with female sockets manufactured by Switchcraft Inc. in the Q-G® D series. This component is designed for audio and instrumentation applications requiring panel-mount circular connectors with solder cup termination. The D3FBAU is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

The D3FBXAU qualifies as a direct substitute for the D3FBAU based on identical electrical and mechanical parameters. Substitution is determined by the following critical parameters:

• Connector type and gender (Plug, Female Sockets)
• Position count (3 positions)
• Shell size and insert specification (XLR)
• Mounting configuration (Panel Mount with Flange)
• Termination method (Solder Cup)
• Fastening mechanism (Latch Lock)
• Electrical ratings (15A, 125VAC)
• Material specifications (Stainless Steel shell, Phosphor Bronze contacts, Gold mating finish)

The D3FBXAU maintains full compatibility with the D3FBAU across all specified parameters while offering the advantage of active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The D3FBXAU is the direct equivalent for the obsolete D3FBAU. Selection of the D3FBXAU is supported by:

• Identical electrical and mechanical specifications across all critical parameters
• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance, providing regulatory advantage over the non-compliant D3FBAU
• Maintained REACH unaffected status and EAR99 export classification
• Equivalent packaging availability (Bulk packaging for D3FBXAU)

For applications requiring the D3FBAU, the D3FBXAU provides full functional and physical compatibility with improved compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the D3FBXAU directly replace the D3FBAU in existing designs?

A: Yes. The D3FBXAU maintains identical electrical ratings (15A, 125VAC), mechanical configuration (3-position XLR plug with female sockets, panel mount flange), termination method (solder cup), and material specifications (stainless steel shell, phosphor bronze contacts, gold mating finish).

Q: What is the primary difference between these parts?

A: The D3FBAU is obsolete, while the D3FBXAU is active. Additionally, the D3FBXAU is ROHS3 compliant, whereas the D3FBAU is RoHS non-compliant.

Q: Are there packaging differences?

A: The D3FBAU packaging specification is not provided. The D3FBXAU is available in Bulk packaging.

Q: Do these parts share the same base product number?

A: Yes. Both parts are derived from base product number D3F within the Q-G® D series from Switchcraft Inc.

Q: Are the connector orientations and fastening mechanisms identical?

A: Yes. Both parts feature keyed orientation and latch lock fastening, ensuring mechanical compatibility in panel mount applications.
