Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Pomona Electronics 5117A must satisfy the following critical parameters to ensure functional equivalence:

• Connector type: Receptacle with male pins
• Position count: 3 positions
• Shell size: XLR configuration
• Mounting: Panel mount with flange
• Termination method: Solder
• Fastening mechanism: Latch lock
• Regulatory compliance: ROHS3 compliant and REACH unaffected

The Switchcraft Inc. PQG3MST102 meets all mandatory substitution criteria. While material composition differs (thermoplastic versus zinc die cast), both configurations provide equivalent electrical and mechanical performance for XLR 3-position circular connector applications. The substitute part maintains identical connector topology, pin configuration, mounting interface, and solder termination capability.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft Inc. PQG3MST102 serves as the primary substitute for the obsolete Pomona Electronics 5117A. Selection is based on the following engineering criteria:

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements. The Switchcraft component is currently in active production, ensuring long-term availability and supply chain continuity. The substitute part preserves all critical connector interface specifications: 3-position XLR configuration, receptacle with male pins, panel mount flange, solder termination, and latch lock fastening.

Material differences between zinc die cast and thermoplastic construction do not affect functional equivalence for standard XLR circular connector applications. The Switchcraft part includes additional features such as board guide, board lock, and ground provisions, which enhance mechanical stability without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft PQG3MST102 directly replace the Pomona 5117A in existing designs?

A: Yes. Both connectors share identical XLR 3-position circular connector topology, panel mount flange interface, solder termination, and latch lock fastening. The connector mating face and pin configuration are equivalent, enabling direct substitution in PCB and panel mount applications.

Q: What are the material differences between these connectors?

A: The Pomona 5117A uses zinc die cast metal construction with nickel plating. The Switchcraft PQG3MST102 employs thermoplastic glass-filled material. Both materials provide adequate mechanical strength and environmental protection for XLR connector applications. Material selection does not affect electrical performance or mating interface compatibility.

Q: Are both connectors compliant with current environmental regulations?

A: Yes. Both the Pomona 5117A and Switchcraft PQG3MST102 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions.

Q: What is the significance of the Switchcraft part being in active production status?

A: Active production status ensures ongoing component availability, established supply chains, and manufacturer support. The obsolete status of the Pomona 5117A makes the active Switchcraft alternative the recommended choice for new designs and long-term system maintenance.

Q: Are there differences in contact finish between these connectors?

A: The Pomona 5117A features nickel contact finish at the mating interface. The Switchcraft PQG3MST102 uses electro-tin contact finish. Both finishes provide adequate corrosion resistance and electrical conductivity for XLR connector applications. Contact finish differences do not prevent functional substitution.

Q: Does the Switchcraft connector include additional features?

A: The Switchcraft PQG3MST102 includes board guide, board lock, and ground features. These enhancements provide improved mechanical stability and grounding capability without affecting compatibility with the Pomona 5117A interface specifications.
