E3FBAU Equivalent & Substitute Parts

Part Overview

The E3FBAU is a 3-position circular connector plug with female sockets manufactured by Switchcraft Inc. under the Q-G® E series. This connector is designed for audio and instrumentation applications requiring panel-mount installation with solder termination. The part is currently active in production with 1012 units in stock. Equivalent parts are identified when applications require alternative sourcing, inventory availability, or specific operational parameter alignment within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

The AC3FDZB-AU from Amphenol Audio qualifies as an equivalent substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Plug, Female Sockets
• Number of positions: 3
• Shell size: XLR
• Mounting configuration: Panel Mount with Flange
• Fastening mechanism: Latch Lock
• Keyed orientation
• Shielded design
• Current rating: 15A
• Shell material: Zinc Die Cast
• Contact finish: Gold plating
• RoHS3 compliance
• REACH unaffected status

Operational Differences: The AC3FDZB-AU operates within a narrower temperature range (-25°C ~ 75°C) compared to the E3FBAU (-55°C ~ 85°C). The substitute features solder cup termination versus solder termination on the main part. Contact material differs: phosphor bronze in the substitute versus copper alloy in the main part. The substitute includes IP40 ingress protection and UL94 V-0 flammability rating.

Parameter Comparison

Engineering Selection Recommendations

Both the E3FBAU and AC3FDZB-AU maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The E3FBAU is suitable for applications requiring extended temperature operation down to -55°C and up to 85°C. The AC3FDZB-AU is appropriate for standard industrial and audio applications operating within -25°C to 75°C, with the added benefit of IP40 ingress protection and UL94 V-0 flammability certification. Selection between these parts depends on specific application temperature requirements and environmental protection specifications.

Frequently Asked Questions (FAQ)

Q: Can AC3FDZB-AU replace E3FBAU in all applications?

A: Substitution is valid for applications operating within the -25°C to 75°C temperature range. Applications requiring operation below -25°C or above 75°C must use the E3FBAU.

Q: What is the difference between solder and solder cup termination?

A: Both termination methods provide electrical connection through solder. Solder cup termination features a cup-shaped contact designed to accept stranded wire, while standard solder termination accommodates wire directly to the contact surface.

Q: Are the connectors mechanically interchangeable?

A: Yes. Both connectors share identical XLR shell size, 3-position configuration, panel-mount flange design, and latch lock fastening. Physical installation is interchangeable.

Q: Does the AC3FDZB-AU provide better environmental protection?

A: The AC3FDZB-AU includes IP40 ingress protection and UL94 V-0 flammability rating. The E3FBAU does not specify these certifications. IP40 protection is suitable for environments with limited dust and moisture exposure.

Q: What is the inventory status for each part?

A: E3FBAU has 1012 units in stock. AC3FDZB-AU has 1450 units in stock.

Q: Are both parts RoHS compliant?

A: Yes. Both E3FBAU and AC3FDZB-AU are ROHS3 compliant and REACH unaffected.
