Key Parameters

Substitute Part Grouping Explanation

Substitution of the A6FBAU is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Plug, Female Sockets)
• Position count (6 positions)
• Shell size designation (XLR)
• Termination method (Solder Cup)
• Fastening mechanism (Latch Lock)
• Electrical ratings (7.5A, 125VAC)
• Mechanical compatibility (Cable opening range, shell material, contact finish)
• Feature set (Backshell, Cable Clamp, Ground, Strain Relief)

The A6FBXAU meets all these criteria and is classified as a direct substitute. Both parts maintain identical mechanical and electrical specifications, with the primary distinction being product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The A6FBXAU is the direct functional equivalent of the A6FBAU. Both connectors are electrically and mechanically identical across all specified parameters. The A6FBXAU is recommended for new designs and ongoing procurement due to its active product status and ROHS3 compliance certification. The A6FBAU, classified as obsolete, should be replaced with the A6FBXAU in applications where component availability and regulatory compliance are required. Existing installations using the A6FBAU may continue operation without modification, as the A6FBXAU maintains full backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can the A6FBXAU be used as a direct replacement for the A6FBAU in existing assemblies?

A: Yes. The A6FBXAU is mechanically and electrically identical to the A6FBAU. Both connectors feature the same 6-position XLR configuration, solder cup termination, latch lock fastening, and electrical ratings (7.5A, 125VAC). No design modifications are required.

Q: What is the primary difference between these two parts?

A: The A6FBAU is obsolete, while the A6FBXAU is active. Additionally, the A6FBXAU is ROHS3 compliant, whereas the A6FBAU is RoHS non-compliant. Functionally, both parts are equivalent.

Q: Are there packaging differences between A6FBAU and A6FBXAU?

A: The A6FBXAU is supplied in bulk packaging. The A6FBAU packaging specification is not provided. For procurement purposes, confirm packaging requirements with the supplier.

Q: What cable opening range is supported by these connectors?

A: Both connectors support cable openings from 0.210" to 0.300" (5.33mm to 7.62mm). Ensure cable diameter falls within this range for proper strain relief and cable clamp engagement.

Q: Are these connectors suitable for audio and instrumentation applications?

A: Yes. Both the A6FBAU and A6FBXAU are specified for audio and instrumentation applications. The gold-plated contacts and stainless steel shell provide reliable performance in these environments.
