Switchcraft D3FB Equivalent & Substitute Parts

Part Overview

The Switchcraft D3FB is a 3-position circular connector plug with female sockets, designed for audio and instrumentation applications. It features a stainless steel shell with silver-plated phosphor bronze contacts, rated for 15A at 125VAC, and utilizes solder cup termination with panel mount flange configuration. The D3FB is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The D3FB has one direct substitute: the D3FBX. Substitution eligibility is determined by matching the following critical parameters:

• Connector type and gender (Plug, Female Sockets)
• Number of positions (3)
• Shell size designation (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, Silver plating)
• Series designation (Q-G® D)

The D3FBX maintains identical electrical and mechanical specifications to the D3FB, with the primary distinction being product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The D3FBX is the direct active equivalent for the obsolete D3FB. Both parts are manufactured by Switchcraft Inc. and maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, shell size, mounting configuration, termination method, and electrical ratings.

The primary distinction between the two parts is product status and regulatory compliance. The D3FB is classified as obsolete, while the D3FBX is active and ROHS3 compliant. For new designs and ongoing procurement, the D3FBX is the appropriate selection. For legacy system maintenance where the D3FB is currently specified, the D3FBX provides direct functional and physical compatibility without design modification.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, and both are REACH unaffected. The D3FBX is available in bulk packaging, whereas the D3FB is supplied in standard packaging.

Frequently Asked Questions (FAQ)

Q: Can the D3FBX be used as a direct replacement for the D3FB in existing assemblies?

A: Yes. The D3FBX maintains identical connector type, position count, shell size, mounting configuration, termination method, and electrical ratings. Physical and functional compatibility is complete.

Q: What is the primary reason for substituting the D3FB with the D3FBX?

A: The D3FB is classified as obsolete. The D3FBX is the active equivalent part from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between the D3FB and D3FBX?

A: Yes. The D3FB is RoHS non-compliant, while the D3FBX is ROHS3 compliant. For applications subject to RoHS requirements, the D3FBX is the required selection.

Q: Do the D3FB and D3FBX have different electrical ratings?

A: No. Both parts are rated for 15A at 125VAC and maintain identical contact materials, finishes, and current-carrying capacity.

Q: What packaging options are available?

A: The D3FB is supplied in standard packaging, while the D3FBX is available in bulk packaging. Packaging selection should align with procurement volume and inventory management requirements.

Q: Are both parts suitable for audio and instrumentation applications?

A: Yes. Both the D3FB and D3FBX are specified for audio and instrumentation applications with identical mechanical and electrical characteristics.
