Substitute Part Grouping Explanation

Substitution of the PHG.0K.307.CLLC40Z is permissible with parts meeting the following criteria:

• Connector type: Receptacle with female sockets
• Number of positions: 7
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shell material: Brass with metallic finish
• Contact finish: Gold plating on mating surfaces
• Ingress protection: IP68 minimum (equivalent to or exceeding IP66/IP68)
• Insert material: PEEK or equivalent dielectric
• Compliance: ROHS3 and REACH requirements

The ODU K20K0C-P07LCC0-400S meets these core substitution criteria. Variations in current rating, operating temperature range, and backshell features are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.307.CLLC40Z and K20K0C-P07LCC0-400S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Selection between these parts depends on application-specific requirements:

The PHG.0K.307.CLLC40Z is suitable for applications requiring extended operating temperature range (-55°C to 200°C) and shielded construction. The higher temperature capability accommodates harsh industrial and aerospace environments.

The K20K0C-P07LCC0-400S provides higher current capacity (4A versus 2.5A) and includes integrated strain relief in addition to backshell protection. This configuration is appropriate for applications with elevated current demands and mechanical stress considerations. The operating temperature range (-40°C to 120°C) is suitable for industrial, medical, military, and testing equipment applications.

Both connectors feature identical core specifications: 7-position female socket receptacles with solder cup termination, push-pull fastening, brass shells with gold-plated contacts, PEEK inserts, and IP68 ingress protection. Cable opening dimensions are compatible within tolerance.

Frequently Asked Questions (FAQ)

Q: Can the K20K0C-P07LCC0-400S directly replace the PHG.0K.307.CLLC40Z in all applications?

A: Direct substitution is permissible when the application operating temperature does not exceed 120°C and current requirements do not exceed 4A. The PHG.0K.307.CLLC40Z must be retained for applications requiring temperatures above 120°C or extended low-temperature operation below -40°C.

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

A: Both connectors share identical mechanical and electrical core specifications: 7-position female socket receptacles, solder cup termination, push-pull fastening, brass construction with gold-plated contacts, PEEK inserts, and IP68 ingress protection. Cable opening dimensions are compatible.

Q: Are there differences in shielding between these parts?

A: The PHG.0K.307.CLLC40Z is specified as shielded. The K20K0C-P07LCC0-400S does not list shielding in its specifications. Applications requiring electromagnetic shielding should retain the LEMO part.

Q: What is the significance of the shell finish difference?

A: The PHG.0K.307.CLLC40Z features chrome plating directly on brass. The K20K0C-P07LCC0-400S uses chrome over nickel plating. Both finishes provide corrosion resistance and are suitable for standard industrial environments. The nickel underplate in the ODU part provides additional corrosion protection in harsh environments.

Q: How do the current ratings affect component selection?

A: The PHG.0K.307.CLLC40Z is rated for 2.5A maximum current. The K20K0C-P07LCC0-400S is rated for 4A. Selection should be based on actual circuit current requirements. The higher-rated ODU connector provides additional margin in applications approaching 2.5A.

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

A: Both parts are ROHS3 compliant and REACH unaffected. The K20K0C-P07LCC0-400S is explicitly listed for medical and military applications. The PHG.0K.307.CLLC40Z is active production with equivalent compliance status. Application-specific qualification requirements should be verified with end-use documentation.
