Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.0K.305.CLLC40Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle with female sockets in 5-position configuration
• Termination Method: Solder cup termination required for PCB assembly compatibility
• Fastening Mechanism: Push-pull fastening type for mating interface consistency
• Contact Material & Finish: Gold-plated mating surface for electrical performance and corrosion resistance
• Shell Material: Brass construction with appropriate plating for environmental durability
• Ingress Protection: Minimum IP66 rating for sealed applications
• Current Capacity: Rated for 6.5A or higher to maintain electrical performance margins
• Operating Temperature Range: Must support -55°C to 200°C or equivalent operational envelope
• Cable Opening Tolerance: 0.142" ~ 0.157" (3.60mm ~ 4.00mm) for cable strain relief compatibility
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

The substitute part K20K0C-P05LFG0-400S meets these criteria within the allowed parameter specifications for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.305.CLLC40Z and K20K0C-P05LFG0-400S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The PHG.0K.305.CLLC40Z provides an extended operating temperature range of -55°C to 200°C, making it suitable for high-temperature applications. The K20K0C-P05LFG0-400S operates within -40°C to 120°C, appropriate for standard industrial and medical environments.

The K20K0C-P05LFG0-400S offers a higher current rating of 7.5A compared to 6.5A, providing additional electrical capacity. Both parts maintain compatible cable opening tolerances and identical solder cup termination, contact finish, and fastening mechanisms.

Selection between these parts should be based on specific application temperature requirements and current load specifications. Both parts are suitable for industrial, medical, military, and testing equipment applications where push-pull circular connectors with solder cup termination are required.

Frequently Asked Questions (FAQ)

Q: Can the K20K0C-P05LFG0-400S directly replace the PHG.0K.305.CLLC40Z in all applications?

A: Direct replacement is possible for applications operating within -40°C to 120°C with current loads up to 7.5A. Applications requiring operation below -40°C or above 120°C must use the PHG.0K.305.CLLC40Z due to its extended temperature range of -55°C to 200°C.

Q: Are the cable opening tolerances compatible between these two connectors?

A: The cable opening tolerances are substantially compatible. The PHG.0K.305.CLLC40Z specifies 0.142" ~ 0.157" (3.60mm ~ 4.00mm), while the K20K0C-P05LFG0-400S specifies 0.138" ~ 0.157" (4.60mm ~ 4.00mm). The overlap range of 0.142" ~ 0.157" ensures compatible cable strain relief performance.

Q: What is the difference in shell finish between these connectors?

A: The PHG.0K.305.CLLC40Z uses chrome plating directly on brass, while the K20K0C-P05LFG0-400S uses chrome over nickel plating. Both finishes provide corrosion resistance; the nickel underplate in the ODU part offers additional protection in harsh environments.

Q: Do both connectors meet the same ingress protection standards?

A: The PHG.0K.305.CLLC40Z is rated IP66/IP68, while the K20K0C-P05LFG0-400S is rated IP68. Both meet waterproof and dust-tight requirements. The PHG.0K.305.CLLC40Z additionally supports IP66 for high-pressure jet applications.

Q: Are solder cup terminations identical between these parts?

A: Both connectors use solder cup termination with identical mechanical interfaces. Solder cup dimensions and PCB pad layouts are compatible for direct substitution in assembly processes.

Q: What regulatory certifications apply to both parts?

A: Both the PHG.0K.305.CLLC40Z and K20K0C-P05LFG0-400S are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for industrial and commercial markets.
