Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PHG.0K.305.CLLC45Z are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type & Position Count: Receptacle configuration with 5 female socket positions
• Termination Method: Solder cup termination for direct PCB or cable assembly
• Fastening Mechanism: Push-pull coupling system
• Ingress Protection: IP66/IP68 rating for sealed, waterproof applications
• Contact Material & Finish: Gold-plated mating surfaces for reliable electrical connection
• Shell Construction: Brass material with protective finish
• Current Capacity: Minimum 6.5A rating to support equivalent load requirements
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The substitute part K20K0C-P05LFG0-450S from ODU meets these core substitution criteria, maintaining functional equivalence across the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.305.CLLC45Z and K20K0C-P05LFG0-450S maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The ODU substitute provides equivalent or superior electrical performance with a 7.5A current rating compared to the 6.5A specification of the LEMO part.

Selection between these parts should account for the following provided specifications:

• Operating Temperature Range: The LEMO part supports -55°C ~ 200°C, while the ODU part operates within -40°C ~ 120°C. Applications requiring extended low-temperature operation below -40°C or high-temperature operation above 120°C necessitate the LEMO PHG.0K.305.CLLC45Z.
• Cable Opening Tolerance: Both parts accommodate 4.00mm ~ 4.50mm cable diameters with minor variance at the lower tolerance limit (0.157" vs 0.161").
• Ingress Protection: The ODU part specifies IP68 (waterproof), while the LEMO part provides IP66/IP68 (dust tight and waterproof), offering equivalent sealing performance for submerged applications.
• Regulatory Classification: Both parts carry EAR99 export classification and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the K20K0C-P05LFG0-450S replace the PHG.0K.305.CLLC45Z in all applications?

A: Substitution is valid for applications operating within -40°C ~ 120°C temperature range. Applications requiring operation below -40°C or above 120°C require the LEMO part to meet temperature specifications.

Q: Are the solder cup terminations mechanically compatible?

A: Both parts feature solder cup termination and are compatible with equivalent PCB pad layouts and cable assembly processes. Cable opening ranges overlap within 4.00mm ~ 4.50mm, supporting standard cable gauges.

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

A: The LEMO part uses Chrome finish on brass, while the ODU part uses Chrome over Nickel on brass. Both finishes provide corrosion resistance; the nickel underplate in the ODU part offers additional protection in harsh environments.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export purposes. Moisture Sensitivity Level is 1 (Unlimited) for both, indicating no special handling requirements.

Q: Is the higher current rating of the ODU part a concern?

A: The ODU part's 7.5A rating exceeds the LEMO specification of 6.5A, providing additional current capacity margin. This does not create compatibility issues; it represents improved electrical performance headroom.
