Substitute Part Grouping Explanation

Substitution of the PHG.0K.304.CLLC35Z is permissible with the ODU K20K0C-P04LFG0-350S based on the following alignment of critical parameters:

Matching Parameters:

• Connector type: Receptacle, female sockets
• Number of positions: 4
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding: Shielded construction
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass
• Insert material: PEEK
• Ingress protection: IP68 (exceeds IP66/IP68 requirement)
• Current rating: 7.5A (exceeds 7A requirement)
• Cable opening range: 0.118" ~ 0.138" (3.00mm ~ 4.60mm) overlaps with 0.122" ~ 0.138" (3.10mm ~ 4.60mm)
• RoHS compliance: ROHS3 compliant
• Moisture sensitivity: MSL 1 (unlimited)

Differing Parameters:

• Operating temperature: ODU substitute rated -40°C ~ 120°C versus LEMO -55°C ~ 200°C
• Shell finish: ODU uses chrome over nickel versus LEMO chrome
• Backshell features: ODU includes strain relief in addition to backshell

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.304.CLLC35Z and K20K0C-P04LFG0-350S are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. The ODU K20K0C-P04LFG0-350S provides equivalent or superior electrical performance with a higher current rating of 7.5A compared to 7A.

Selection between these parts depends on application-specific temperature requirements. The LEMO PHG.0K.304.CLLC35Z supports extended operating temperatures from -55°C to 200°C, making it suitable for high-temperature applications. The ODU K20K0C-P04LFG0-350S operates within -40°C to 120°C, appropriate for industrial, medical, military, and testing equipment applications within this temperature envelope.

Both connectors maintain compatible cable opening specifications with overlapping ranges, ensuring mechanical compatibility with standard cable assemblies. The ODU substitute includes integrated strain relief in addition to backshell features, providing enhanced mechanical protection.

Frequently Asked Questions (FAQ)

Q: Can the ODU K20K0C-P04LFG0-350S directly replace the LEMO PHG.0K.304.CLLC35Z in all applications?

A: Direct substitution is permissible when the application operating temperature remains within -40°C to 120°C. Applications requiring temperatures below -40°C or above 120°C must retain the LEMO part.

Q: What are the key compatibility factors for substitution?

A: The critical compatibility parameters are: 4-position configuration, female socket receptacle type, solder cup termination, push-pull fastening, shielded construction, and gold contact finish. Both parts meet these requirements.

Q: How do the current ratings compare?

A: The ODU substitute is rated for 7.5A versus the LEMO part at 7A. The higher rating of the substitute provides additional margin for applications at or near the 7A threshold.

Q: Are there differences in ingress protection ratings?

A: The LEMO part is rated IP66/IP68, while the ODU substitute is rated IP68. The ODU rating meets or exceeds the LEMO specification.

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

A: The LEMO part uses chrome finish, while the ODU substitute uses chrome over nickel. Both provide corrosion resistance; the nickel underplate in the ODU part offers additional corrosion protection in harsh environments.

Q: Do both parts use the same insert material?

A: Yes, both connectors use polyetheretherketone (PEEK) for the insert material, ensuring consistent dielectric properties and mechanical stability.

Q: What packaging options are available?

A: The LEMO PHG.0K.304.CLLC35Z is available in standard packaging with 662 units in stock. The ODU K20K0C-P04LFG0-350S is available in bulk packaging with 805 units in stock.
