Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.0K.309.CLLC50Z is determined by the following critical parameters:

• Connector type: Receptacle with female sockets
• Number of positions: 9
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding requirement: Shielded construction
• Ingress protection: IP66/IP68 rating
• Contact finish: Gold plating on mating surfaces
• Insert material: Polyetheretherketone (PEEK)
• Mounting configuration: Free hanging (in-line)

The substitute part K20K0C-P09LCC0-500S from ODU meets these core functional requirements, enabling direct substitution in applications where connector compatibility is the primary selection criterion.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.309.CLLC50Z and K20K0C-P09LCC0-500S are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific requirements:

The PHG.0K.309.CLLC50Z supports an extended operating temperature range of -55°C to 200°C, making it suitable for high-temperature applications. The K20K0C-P09LCC0-500S operates within -40°C to 120°C and provides a higher current rating of 4A compared to the 2A rating of the LEMO part. Both connectors meet IP68 waterproof specifications and utilize identical termination and fastening methods. The cable opening dimensions are compatible within the specified ranges.

Frequently Asked Questions (FAQ)

Q: Can K20K0C-P09LCC0-500S directly replace PHG.0K.309.CLLC50Z in all applications?

A: Direct substitution is possible for applications operating within the temperature range of -40°C to 120°C and requiring current ratings up to 4A. Applications requiring operation above 120°C or below -40°C require the LEMO part.

Q: What are the key compatibility factors between these connectors?

A: Both connectors share identical core specifications: 9-position receptacle configuration, female sockets, solder cup termination, push-pull fastening, shielded construction, gold contact finish, and PEEK insert material. These parameters ensure mechanical and electrical compatibility.

Q: Are there differences in shell finish that affect performance?

A: The PHG.0K.309.CLLC50Z features chrome plating on brass, while the K20K0C-P09LCC0-500S features chrome over nickel plating. Both finishes provide corrosion resistance appropriate for IP68-rated applications.

Q: What is the significance of the current rating difference?

A: The ODU part supports 4A versus the LEMO part's 2A rating. Applications requiring current levels between 2A and 4A must use the K20K0C-P09LCC0-500S. Applications limited to 2A or below can use either part.

Q: Are both parts suitable for industrial and medical applications?

A: Both parts meet ROHS3 compliance and REACH requirements. The ODU part explicitly lists industrial, medical, military, and testing equipment applications. Application suitability depends on specific environmental and performance requirements beyond the provided specifications.
