Key Parameters

Substitute Part Grouping Explanation

Substitution of the A3FBAU is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part A3FBXAU maintains identical specifications for connector type, position count, shell size, termination method, fastening mechanism, current and voltage ratings, cable opening dimensions, shell material, contact finish, and integrated features. Both parts are manufactured by Switchcraft Inc. within the Q-G® A series and are designed for the same audio and instrumentation applications.

The primary distinction between these parts is product status and regulatory compliance. The A3FBAU is obsolete, while the A3FBXAU is active and RoHS3 compliant, making it the current production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The A3FBXAU is the direct active equivalent for the obsolete A3FBAU. Both parts are electrically and mechanically identical across all specified parameters. The A3FBXAU is the recommended selection for new designs and ongoing procurement due to its active product status and RoHS3 compliance. Systems currently using the A3FBAU can transition to the A3FBXAU without modification, as all critical dimensions, electrical ratings, and mechanical interfaces remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the A3FBXAU directly replace the A3FBAU in existing assemblies? A: Yes. The A3FBXAU is mechanically and electrically identical to the A3FBAU across all specified parameters, including connector type, position count, shell size, termination method, current and voltage ratings, and cable opening dimensions.

Q: What is the primary difference between these two parts? A: The A3FBAU is obsolete, while the A3FBXAU is an active product. The A3FBXAU also carries RoHS3 compliance, whereas the A3FBAU is RoHS non-compliant.

Q: Are there packaging differences between the A3FBAU and A3FBXAU? A: The A3FBAU is supplied in standard packaging, while the A3FBXAU is supplied in bulk packaging. This difference does not affect the connector's electrical or mechanical performance.

Q: What applications are these connectors suitable for? A: Both the A3FBAU and A3FBXAU are designed for audio and instrumentation applications, with a 15A current rating and 125VAC voltage rating.

Q: Are these connectors compatible with standard XLR systems? A: Yes. Both connectors feature XLR shell size and are designed for standard XLR applications with 3-position configuration.
