Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.1K.307.CLLC55 is determined by the following critical parameters:

• Connector Type & Position Count: Receptacle, female sockets, 7-position configuration
• Termination Method: Solder cup termination for PCB or cable assembly integration
• Fastening Mechanism: Push-pull coupling for secure mating and unmating
• Electrical Performance: Current rating and contact finish (gold plating) for signal integrity
• Environmental Sealing: IP66/IP68 ingress protection for dust and water resistance
• Material Compatibility: Brass shell with chrome finish and PEEK insert for mechanical durability
• Temperature Range: Operating capability across specified thermal limits
• Cable Opening Tolerance: Physical accommodation of cable diameters within specified range

The substitute part K11K0C-P07LFG0-5500 (ODU MINI-SNAP® K series) meets the core functional requirements: 7-position receptacle with female sockets, solder cup termination, push-pull fastening, gold-plated contacts, brass shell with chrome finish, PEEK insert, and IP68 ingress protection. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.1K.307.CLLC55 and K11K0C-P07LFG0-5500 are active production parts with ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for equivalent substitution in most applications.

PHG.1K.307.CLLC55 (LEMO) is the primary specification. Select this part when:

• Extended operating temperature range (-55°C to 200°C) is required
• IP66 ingress protection level is specified
• LEMO connector ecosystem integration is preferred

K11K0C-P07LFG0-5500 (ODU MINI-SNAP® K) is a functional equivalent. Select this part when:

• Operating temperature range of -40°C to 120°C is acceptable
• IP68 ingress protection is sufficient
• ODU connector ecosystem integration is preferred
• Slightly higher current rating (7.5A vs 7A) provides additional margin
• Cable opening tolerance of 5.00mm minimum is compatible with application requirements

Both parts share identical core specifications: 7-position receptacle configuration, female sockets, solder cup termination, push-pull fastening, gold-plated contacts, brass shell with chrome finish, and PEEK insert material. Selection between these parts should be based on application-specific temperature and ingress protection requirements.

Frequently Asked Questions (FAQ)

Q: Can K11K0C-P07LFG0-5500 replace PHG.1K.307.CLLC55 in all applications?

A: Substitution is valid when the application operating temperature range does not exceed -40°C to 120°C and IP68 ingress protection meets or exceeds the design requirement. If the application requires operation below -40°C or above 120°C, the PHG.1K.307.CLLC55 must be used.

Q: What are the differences in shell finish between these connectors?

A: The PHG.1K.307.CLLC55 features chrome finish on brass shell. The K11K0C-P07LFG0-5500 features chrome over nickel finish on brass shell. Both finishes provide corrosion resistance; the nickel underplate in the ODU part provides additional protection in certain corrosive environments.

Q: Are the cable opening tolerances compatible?

A: The PHG.1K.307.CLLC55 accepts cables with diameters of 5.10mm to 5.50mm. The K11K0C-P07LFG0-5500 accepts cables with diameters of 5.00mm to 5.50mm. The ODU part accommodates slightly smaller minimum cable diameter. Verify cable diameter compatibility with your specific application.

Q: Do both connectors support the same current rating?

A: The PHG.1K.307.CLLC55 is rated for 7A. The K11K0C-P07LFG0-5500 is rated for 7.5A. Both ratings are suitable for equivalent applications; the ODU part provides 0.5A additional capacity.

Q: Are both parts RoHS compliant?

A: Yes, both the PHG.1K.307.CLLC55 and K11K0C-P07LFG0-5500 are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the primary reason to consider a substitute part?

A: Substitute parts are identified for supply chain flexibility when the primary part (PHG.1K.307.CLLC55) experiences extended lead times or inventory constraints. The K11K0C-P07LFG0-5500 provides functional equivalence for applications within its specified operating parameters.
