D5FBAU Equivalent & Substitute Parts

Part Overview

The D5FBAU is a 5-position circular connector plug with female sockets manufactured by Switchcraft Inc. in the Q-G® D series. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and system maintenance. The D5FBAU serves audio and instrumentation applications requiring panel-mount circular connectors with solder cup termination and latch lock fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D5FBAU is determined by strict equivalence across the following critical parameters:

• Connector type (Plug, Female Sockets)
• Number of positions (5)
• Shell size and insert specification (XLR)
• Mounting configuration (Panel Mount with Flange)
• Termination method (Solder Cup)
• Fastening mechanism (Latch Lock)
• Keyed orientation
• Electrical ratings (7.5A at 125VAC)
• Material specifications (Stainless Steel shell, Phosphor Bronze contacts, Gold mating finish, Polyester insert)

The D5FBXAU meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete D5FBAU.

Parameter Comparison

Engineering Selection Recommendations

The D5FBXAU is the direct equivalent substitute for the obsolete D5FBAU. Both parts are manufactured by Switchcraft Inc. and share identical electrical, mechanical, and material specifications across all functional parameters.

The primary distinction between the two parts is regulatory compliance status. The D5FBXAU is ROHS3 compliant, whereas the D5FBAU is RoHS non-compliant. For new designs or systems requiring RoHS compliance, the D5FBXAU is the appropriate selection. The D5FBXAU is currently in active production status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can D5FBXAU directly replace D5FBAU in existing assemblies?

A: Yes. The D5FBXAU is a direct functional equivalent. All mechanical mounting dimensions, electrical ratings, connector pin configurations, and termination methods are identical. No circuit modifications or mechanical redesign is required.

Q: What is the difference between D5FBAU and D5FBXAU?

A: The parts are functionally identical. The D5FBXAU is the active production variant with ROHS3 compliance, while the D5FBAU is obsolete and RoHS non-compliant. Packaging differs (Bulk for D5FBXAU versus unspecified for D5FBAU).

Q: Are there any compatibility concerns with solder cup termination?

A: No. Both parts use identical solder cup termination. Wire gauge and solder joint procedures remain unchanged between the two part numbers.

Q: Does the XLR shell size remain the same?

A: Yes. Both parts use XLR shell size with 5-position inserts. Mating connector compatibility is maintained.

Q: What is the current availability status?

A: D5FBXAU is in active production with 833 pieces in stock. D5FBAU is obsolete with 895 pieces in remaining inventory.
