Pomona Electronics 5126A Circular Connector - Equivalent & Substitute Parts

Part Overview

The Pomona Electronics 5126A is a 5-position circular connector plug with male pins designed for solder termination. This component features a zinc die-cast shell with nickel finish and silver contact plating, incorporating a cable clamp and latch lock fastening mechanism for secure in-line connections.

The 5126A carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system compatibility, ensure continued availability for maintenance and repair applications, and support ongoing production requirements where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5126A is determined by strict alignment across the following critical parameters:

• Connector Configuration: Plug connector with male pins in 5-position XLR format
• Termination Method: Solder termination required for PCB and cable assembly compatibility
• Mechanical Interface: Free hanging in-line mounting with latch lock fastening
• Environmental Protection: Nickel-finished shell with silver-plated mating contacts
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The ITT Cannon XLR512C meets all substitution criteria. Both connectors share identical functional specifications across connector type, position count, shell size, mounting configuration, termination method, and fastening mechanism. Both components maintain ROHS3 compliance and EAR99 export classification.

Parameter Comparison

Engineering Selection Recommendations

The ITT Cannon XLR512C serves as the direct functional equivalent for the obsolete Pomona 5126A. Both connectors maintain identical electrical and mechanical specifications across all critical substitution parameters.

The XLR512C offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Both components satisfy ROHS3 compliance requirements and carry EAR99 export classification, supporting regulatory and procurement requirements without modification.

The primary material difference—aluminum shell in the XLR512C versus zinc die cast in the 5126A—does not affect functional compatibility. Both materials provide equivalent mechanical durability and environmental protection when finished with nickel plating and silver contact plating.

Frequently Asked Questions (FAQ)

Q: Can the ITT Cannon XLR512C directly replace the Pomona 5126A in existing assemblies?

A: Yes. Both connectors share identical specifications for connector type, pin configuration, shell size, mounting method, termination type, and fastening mechanism. The XLR512C is mechanically and electrically compatible with applications designed for the 5126A.

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

A: The 5126A uses zinc die cast while the XLR512C uses aluminum. Both materials are finished with nickel plating, providing equivalent corrosion resistance and environmental protection. This material difference does not affect functional performance or compatibility.

Q: Are both connectors compliant with current regulatory standards?

A: Yes. Both the Pomona 5126A and ITT Cannon XLR512C are ROHS3 compliant and carry EAR99 export classification, meeting current regulatory requirements for electronic component procurement and deployment.

Q: Why is the XLR512C recommended despite the 5126A's availability in inventory?

A: The 5126A carries obsolete product status, indicating discontinued manufacturing and limited long-term availability. The XLR512C maintains active product status, ensuring reliable supply for current and future requirements while providing identical functional performance.

Q: Are there any packaging or ordering considerations when transitioning to the XLR512C?

A: The XLR512C is supplied in bulk packaging, whereas the 5126A packaging specification is not provided. Verify bulk packaging compatibility with your assembly and procurement processes before ordering.
