Key Parameters

Substitute Part Grouping Explanation

Substitution of the A7FBAU is determined by strict equivalence across the following critical parameters:

• Connector type: Plug with female sockets
• Position count: 7 positions
• Shell size: XLR
• Termination method: Solder cup
• Electrical ratings: 5A current, 125VAC voltage
• Shell material: Stainless steel
• Contact finish: Gold plating
• Cable opening range: 0.210" ~ 0.300" (5.33mm ~ 7.62mm)
• Fastening type: Latch lock
• Orientation: Keyed

The A7FBXAU meets all these criteria and is identified as a direct substitute. The primary distinction is product status: A7FBXAU is active and RoHS3 compliant, whereas A7FBAU is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The A7FBXAU is the direct substitute for the obsolete A7FBAU. Both parts are manufactured by Switchcraft Inc. and share identical electrical, mechanical, and dimensional specifications. The A7FBXAU is currently in active production status with full inventory availability.

For new designs or component replacement in systems subject to regulatory compliance requirements, the A7FBXAU is the appropriate selection due to its ROHS3 compliance status. The A7FBAU, being RoHS non-compliant and obsolete, should not be specified for new procurement.

Both parts maintain equivalent performance in audio and instrumentation applications requiring 7-position XLR circular connectors with solder cup termination and 5A/125VAC electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can A7FBXAU be used as a direct replacement for A7FBAU in existing assemblies?

A: Yes. The A7FBXAU is electrically and mechanically equivalent to the A7FBAU. All critical parameters—connector type, position count, shell size, termination method, electrical ratings, and physical dimensions—are identical. The parts are interchangeable in function and form.

Q: What is the primary difference between A7FBAU and A7FBXAU?

A: The primary differences are product status and regulatory compliance. A7FBAU is obsolete and RoHS non-compliant. A7FBXAU is active production and ROHS3 compliant. Both parts are functionally equivalent.

Q: Are there packaging differences between these parts?

A: A7FBXAU is supplied in bulk packaging, while A7FBAU packaging information is not specified. This distinction does not affect electrical or mechanical compatibility.

Q: Which part should be specified for new system designs?

A: A7FBXAU should be specified for all new designs. It is in active production, maintains full regulatory compliance, and provides equivalent performance to the obsolete A7FBAU.

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

A: Yes. Both the A7FBAU and A7FBXAU are rated for audio and instrumentation applications. The 5A/125VAC electrical rating and XLR 7-position configuration support these application categories.
