Substitute Part Grouping Explanation

Substitute parts for the PHG.1K.306.CLLC55Z are identified based on the following critical parameters that determine functional equivalence:

  • Connector Configuration: 6-position receptacle with female sockets
  • Termination Method: Solder cup for direct PCB or cable attachment
  • Fastening Mechanism: Push-pull coupling system
  • Electrical Performance: Current rating of 7A or greater
  • Environmental Protection: IP68 waterproof rating (meets or exceeds IP66/IP68 requirement)
  • Material Compatibility: Brass shell with gold-plated mating contacts and PEEK insert
  • Regulatory Compliance: ROHS3 compliant status

The ODU K21K0C-P06LFG0-550S meets these core substitution criteria as a 6-position circular connector receptacle with female sockets, solder cup termination, push-pull fastening, shielded construction, and ROHS3 compliance.

Engineering Selection Recommendations

Both the PHG.1K.306.CLLC55Z and K21K0C-P06LFG0-550S are active production parts with ROHS3 compliance and REACH unaffected status. The ODU substitute provides equivalent electrical performance with a higher current rating (7.5A versus 7A) and meets IP68 waterproof specifications.

Selection between these parts should account for the operating temperature range differential: the LEMO part supports -55°C to 200°C operation, while the ODU part operates within -40°C to 120°C. Applications requiring extended low-temperature operation below -40°C or sustained high-temperature operation above 120°C necessitate the LEMO PHG.1K.306.CLLC55Z. For standard industrial and commercial applications within the ODU temperature range, the K21K0C-P06LFG0-550S provides functional equivalence with additional current capacity margin.

Frequently Asked Questions (FAQ)

Q: Can the K21K0C-P06LFG0-550S directly replace the PHG.1K.306.CLLC55Z in all applications?

A: Direct replacement is possible for applications operating within -40°C to 120°C. Applications requiring operation below -40°C or above 120°C require the LEMO part to maintain specified performance.

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

A: Both connectors share identical 6-position configuration, female socket receptacle design, solder cup termination, push-pull fastening, and PEEK insert material. Cable opening ranges overlap within 5.10mm to 5.50mm, ensuring mechanical compatibility for standard cable gauges.

Q: How do the current ratings differ between these parts?

A: The LEMO PHG.1K.306.CLLC55Z is rated for 7A, while the ODU K21K0C-P06LFG0-550S is rated for 7.5A. The ODU part provides 7% additional current capacity. Circuit designs operating at or near the 7A limit should account for this differential when selecting the substitute.

Q: Are both parts compliant with current regulatory standards?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging differences exist between these parts?

A: The LEMO part is supplied in standard packaging, while the ODU part is supplied in bulk packaging. Procurement quantities and handling procedures may differ accordingly.
