Switchcraft 2504M Microphone Plug Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft 2504M is a microphone plug connector featuring 4-conductor TRRS (Tip-Ring-Ring-Sleeve) configuration for stereo microphone applications. This connector type is essential in audio equipment requiring balanced or multi-channel microphone signal transmission. With 889 units in current stock, this part remains actively available for new designs and replacement applications. Identifying equivalent substitute parts ensures design flexibility and supply chain continuity when the primary part becomes unavailable or when alternative connector configurations better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Switchcraft 2504M microphone plug connector are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Manufacturer: Switchcraft Inc. (same manufacturer ensures design consistency and quality standards)
• Connector Category: Barrel Connectors (maintains mechanical and electrical interface compatibility)
• Contact Material and Plating: Brass body with Nickel plating (ensures electrical conductivity and corrosion resistance)
• Compliance Standards: RoHS3 Compliant, REACH Unaffected (meets regulatory requirements for equivalent parts)

Secondary Compatibility Factors:

• Connector Type: Microphone connector family (ensures application-level compatibility)
• Shielding: Unshielded configuration (matches electrical isolation characteristics)
• Mounting Type: Free Hanging (In-Line) (ensures mechanical installation compatibility)
• Thread Size: 5/8"-27 (standardized mechanical interface)

The 2501M receptacle connector shares the same manufacturer, material specifications, compliance certifications, and mechanical interface standards, making it a valid substitute within the Switchcraft microphone connector ecosystem.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Status: Both the 2504M and 2501M connectors maintain identical RoHS3 Compliance and REACH Unaffected status, ensuring that either part meets current environmental and regulatory requirements for electronic component manufacturing and deployment.

Inventory Availability: The 2501M substitute part maintains higher current inventory (1084 units) compared to the 2504M (889 units), providing improved supply chain availability for applications where extended lead times must be minimized.

Connector Configuration Differences: The primary distinction between these parts lies in their connector gender and signal conductor count. The 2504M functions as a male plug with 4-conductor TRRS capability, while the 2501M operates as a female receptacle with 2-conductor mono configuration. Selection between these parts depends on the specific application requirement: plug versus receptacle interface, and stereo (4-conductor) versus mono (2-conductor) signal transmission.

Material and Mechanical Specifications: Both connectors utilize identical brass body construction with nickel plating, identical panel hole sizing (0.390" / 9.91mm), and identical thread specifications (5/8"-27), ensuring mechanical interchangeability within the Switchcraft microphone connector family.

Frequently Asked Questions (FAQ)

Q: Can the 2501M receptacle directly replace the 2504M plug in my application?

A: Direct replacement depends on your circuit design. The 2504M is a male plug connector, while the 2501M is a female receptacle connector. These represent opposite genders and require complementary mating connectors. Additionally, the 2504M supports 4-conductor TRRS stereo configuration, while the 2501M supports only 2-conductor mono configuration. Substitution is only valid if your application requires a female receptacle with mono signal transmission.

Q: What does the 4-conductor TRRS configuration in the 2504M provide?

A: The 4-conductor TRRS (Tip-Ring-Ring-Sleeve) configuration in the 2504M provides four separate signal paths, typically used for stereo audio transmission or multi-channel microphone applications. The 2501M mono configuration provides only two conductors, limiting it to single-channel applications.

Q: Are both connectors compliant with current environmental regulations?

A: Yes. Both the 2504M and 2501M maintain RoHS3 Compliance and REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the mechanical interface compatibility between these connectors?

A: Both connectors share identical mechanical specifications: 0.390" (9.91mm) panel hole size and 5/8"-27 thread size. This ensures mechanical compatibility within the Switchcraft microphone connector family, though electrical compatibility depends on conductor count and connector gender matching your application requirements.

Q: Which part should I select based on current inventory?

A: The 2501M maintains higher current inventory (1084 units) compared to the 2504M (889 units). If supply chain continuity is a priority and your application requirements permit mono 2-conductor operation with a female receptacle configuration, the 2501M offers improved availability.

Q: What material specifications do these connectors share?

A: Both connectors utilize brass body construction with nickel contact plating, providing identical electrical conductivity and corrosion resistance characteristics. This ensures consistent performance within the Switchcraft microphone connector product family.
