Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Switchcraft AA3M is determined by the following critical parameters:

• Connector type and pin configuration (Receptacle, Male Pins, 3-position)
• Shell size and insert standard (XLR)
• Termination method (Solder Cup)
• Mounting configuration (Free Hanging, In-Line, Keyed orientation)
• Fastening mechanism (Latch-type fastening)
• Material and finish specifications (Zinc shell, Nickel finish, Silver contact finish)
• Electrical ratings (Current and voltage capacity)
• Regulatory compliance (RoHS3, REACH, ECCN classification)

The Amphenol Audio AC3MM meets these substitution criteria as a functionally equivalent 3-position XLR male pin receptacle with solder cup termination and comparable mechanical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the Switchcraft AA3M and Amphenol Audio AC3MM are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability and lead time requirements
• Specific feature requirements: The AA3M includes ground and strain relief features; the AC3MM provides IP40 ingress protection rating
• Operating temperature range: The AC3MM specifies -25°C ~ 75°C operating range
• Fastening mechanism preference: AA3M uses Latch Lock; AC3MM uses Latch Holder
• Current and voltage ratings: AA3M specifies 15A at 125VAC; AC3MM ratings are not specified in available data

Both parts share identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol Audio AC3MM directly replace the Switchcraft AA3M in existing designs?

A: Both connectors are 3-position XLR male pin receptacles with solder cup termination and keyed orientation. Mechanical and electrical compatibility is established through matching shell size, pin configuration, and termination method. Verify that the specific fastening mechanism (Latch Lock vs. Latch Holder) and feature set (ground, strain relief, ingress protection) meet application requirements.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Fastening type—AA3M uses Latch Lock while AC3MM uses Latch Holder; (2) Features—AA3M includes ground and strain relief; AC3MM provides IP40 ingress protection; (3) Operating temperature—AC3MM specifies -25°C ~ 75°C; (4) Electrical ratings—AA3M specifies 15A at 125VAC while AC3MM ratings are not provided.

Q: Are both parts compliant with current regulations?

A: Yes. Both the Switchcraft AA3M and Amphenol Audio AC3MM are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What cable opening sizes are compatible with these connectors?

A: The Switchcraft AA3M specifies cable opening range of 0.210" to 0.300" (5.33mm to 7.62mm). Cable opening specification for the Amphenol Audio AC3MM is not provided in available technical data.

Q: How do I determine which part is appropriate for my application?

A: Selection should be based on: (1) availability and procurement timeline; (2) operating temperature requirements; (3) ingress protection needs; (4) specific feature requirements (ground connection, strain relief, or IP rating); (5) fastening mechanism compatibility with your assembly process.
