Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.0K.304.CLLC45Z is determined by the following critical parameters:

• Connector type: Receptacle with female sockets
• Position count: 4 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding requirement: Shielded construction
• Contact finish: Gold plating on mating surfaces
• Insert material: PEEK
• Ingress protection: IP66/IP68 minimum
• Current capacity: 7A or greater
• Operating temperature compatibility

The substitute part K20K0C-P04LFG0-450S from ODU meets these core functional and electrical requirements, enabling direct substitution in applications where the specified parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.304.CLLC45Z and K20K0C-P04LFG0-450S are active production parts with ROHS3 compliance and REACH unaffected status. The substitute part K20K0C-P04LFG0-450S provides equivalent functionality with a higher current rating of 7.5A compared to 7A on the primary part.

Selection between these parts should account for operating temperature requirements. The PHG.0K.304.CLLC45Z supports an extended temperature range of -55°C to 200°C, while the K20K0C-P04LFG0-450S operates within -40°C to 120°C. Applications requiring operation below -40°C or above 120°C necessitate the LEMO part. For applications within the -40°C to 120°C range, the ODU substitute provides equivalent performance with regulatory compliance.

Cable opening specifications differ slightly: the LEMO part accommodates 4.10mm to 4.50mm, while the ODU part accommodates 4.00mm to 4.50mm. Mechanical fit verification is required when transitioning between these parts in existing cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the K20K0C-P04LFG0-450S replace the PHG.0K.304.CLLC45Z in all applications?

A: Substitution is valid for applications operating within -40°C to 120°C. Applications requiring operation outside this temperature range require the PHG.0K.304.CLLC45Z due to its extended operating temperature specification of -55°C to 200°C.

Q: Are there differences in mechanical compatibility?

A: Cable opening specifications differ slightly. The PHG.0K.304.CLLC45Z accepts cables of 4.10mm to 4.50mm diameter, while the K20K0C-P04LFG0-450S accepts 4.00mm to 4.50mm. Existing cable assemblies must be verified for fit compatibility when substituting between these parts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are suitable for applications with equivalent regulatory requirements.

Q: What is the difference in current rating between these parts?

A: The PHG.0K.304.CLLC45Z is rated for 7A, while the K20K0C-P04LFG0-450S is rated for 7.5A. The substitute part provides higher current capacity, making it suitable for applications requiring up to 7.5A.

Q: Are both parts available in the same packaging?

A: Both parts are supplied in bulk packaging. Current inventory shows 920 units of the LEMO part and 745 units of the ODU part available.

Q: What connector series do these parts belong to?

A: The PHG.0K.304.CLLC45Z belongs to the LEMO 0K series. The K20K0C-P04LFG0-450S belongs to the ODU MINI-SNAP® K series. These are distinct product families with compatible electrical and mechanical specifications for the parameters listed.
