Key Parameters

Substitute Part Grouping Explanation

Substitution of the Pomona Electronics 5109/POM is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug with female sockets (maintains mating interface compatibility)
• Number of Positions: 3-position configuration (ensures pin count compatibility)
• Shell Size - Insert: XLR standard (guarantees mechanical fit and keying)
• Mounting Type: Free hanging in-line (preserves installation method)
• Termination Method: Solder cup (maintains electrical connection approach)
• Fastening Type: Latch lock (ensures secure mating)
• Orientation: Keyed (prevents incorrect insertion)

The Switchcraft Inc. A3FBX meets all these critical parameters, establishing it as a direct functional equivalent despite differences in shell material, finish specifications, and additional features.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft Inc. A3FBX is the designated equivalent for the obsolete Pomona Electronics 5109/POM. Both components satisfy identical regulatory requirements: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The A3FBX maintains active product status, ensuring ongoing availability and supply chain continuity. The stainless steel shell construction of the A3FBX provides enhanced corrosion resistance compared to the aluminum or zinc shell of the original part, representing a material upgrade suitable for the same application space. Both connectors share identical electrical interface specifications through their XLR 3-position configuration and solder cup termination, enabling direct functional replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft A3FBX directly replace the Pomona 5109/POM in existing assemblies?

A: Yes. Both connectors are 3-position XLR plugs with female sockets, solder cup termination, latch lock fastening, and keyed orientation. The mechanical and electrical interfaces are equivalent, permitting direct substitution.

Q: What is the significance of the shell material difference between these connectors?

A: The Pomona 5109/POM uses aluminum or zinc shell material with nickel finish, while the Switchcraft A3FBX uses stainless steel. Stainless steel provides superior corrosion resistance and durability in demanding environments. Both materials are suitable for the same connector class and application categories.

Q: Are there compliance differences between these parts?

A: No. Both the Pomona 5109/POM and Switchcraft A3FBX are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. They share identical regulatory status and HTSUS classification (8536.69.4020).

Q: Why is the Pomona 5109/POM listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Pomona Electronics. The Switchcraft A3FBX, with active product status, ensures continued availability and supply chain reliability for applications requiring 3-position XLR female plug connectors with solder cup termination.

Q: What packaging options are available for the substitute part?

A: The Switchcraft A3FBX is supplied in bulk packaging, suitable for production and assembly environments requiring standard component quantities.
