Key Parameters

Substitute Part Grouping Explanation

The A5FBXAU qualifies as a direct substitute for the A5FBAU based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, gender, and socket configuration match exactly (Plug, Female Sockets)
• Number of positions is identical (5)
• Shell size and insert type are the same (XLR)
• Termination method is unchanged (Solder Cup)
• Current and voltage ratings are equivalent or higher (7.5A, 125VAC)
• Shell material and contact finish specifications are maintained (Stainless Steel, Gold-plated)
• Cable opening range accommodates the same wire gauges (0.210" ~ 0.300")
• Fastening and mounting configurations are identical (Latch Lock, Free Hanging)

The A5FBXAU maintains all functional and physical compatibility requirements with the obsolete A5FBAU.

Parameter Comparison

Engineering Selection Recommendations

The A5FBXAU is the direct active equivalent for the obsolete A5FBAU. All electrical specifications, mechanical dimensions, and interface parameters are identical. The primary distinction is product status: A5FBXAU is currently in active production, ensuring long-term availability and supply chain continuity.

An additional consideration is regulatory compliance. The A5FBXAU carries ROHS3 certification, whereas the A5FBAU is RoHS non-compliant. For applications subject to RoHS requirements, the A5FBXAU provides the necessary compliance alignment while maintaining full functional equivalence.

Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming equivalent regulatory standing in these categories.

Frequently Asked Questions (FAQ)

Q: Can the A5FBXAU be used as a direct replacement for the A5FBAU in existing designs?

A: Yes. The A5FBXAU maintains identical electrical ratings (7.5A, 125VAC), mechanical dimensions, connector configuration (5-position XLR female plug), and termination method (solder cup). No design modifications are required.

Q: What is the primary reason to transition from A5FBAU to A5FBXAU?

A: The A5FBAU is obsolete. The A5FBXAU is the active equivalent from the same manufacturer, ensuring continued procurement availability and supply chain support.

Q: Are there compliance differences between these parts?

A: Yes. The A5FBXAU is ROHS3 compliant, while the A5FBAU is RoHS non-compliant. For applications requiring RoHS compliance, the A5FBXAU is the appropriate selection. Both parts are REACH Unaffected and classified as EAR99.

Q: Do the packaging options differ?

A: The A5FBAU packaging specification is not defined. The A5FBXAU is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Are the solder cup termination specifications identical?

A: Yes. Both parts feature identical solder cup termination, cable opening range (0.210" ~ 0.300"), and associated features including backshell, cable clamp, ground, and strain relief.

Q: What applications are these connectors rated for?

A: Both parts are specified for audio and instrumentation applications, with identical electrical and mechanical ratings supporting these use cases.
