Engineering Selection Recommendations

Both the PHG.0K.303.CLLC35Z and K20K0C-P03LJG0-350S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Selection Criteria:

LEMO PHG.0K.303.CLLC35Z: Select when extended operating temperature range (-55°C to 200°C) is required or when 8A current rating is necessary for the application.
ODU K20K0C-P03LJG0-350S: Select for industrial, medical, military, and testing equipment applications operating within -40°C to 120°C range with maximum 7.5A current requirements. This part includes strain relief and is available with 1060 units in stock.

Both parts support identical connector configurations (3-position, female sockets, push-pull, solder cup) and meet IP68 waterproof specifications. Verify application-specific temperature and current requirements before final selection.

Frequently Asked Questions (FAQ)

Q: Can K20K0C-P03LJG0-350S directly replace PHG.0K.303.CLLC35Z in all applications?

A: Direct replacement is possible when the application operates within -40°C to 120°C and requires maximum 7.5A current. If your system requires the extended temperature range (-55°C to 200°C) or 8A current rating, the LEMO part is required.

Q: What are the key differences between these two connectors?

A: The primary differences are operating temperature range (LEMO: -55°C to 200°C; ODU: -40°C to 120°C), current rating (LEMO: 8A; ODU: 7.5A), and shell finish (LEMO: Chrome; ODU: Chrome over Nickel). Both share identical connector type, position count, termination method, and fastening mechanism.

Q: Are the cable opening dimensions compatible?

A: The cable opening ranges overlap significantly (3.10mm to 4.60mm for LEMO; 3.00mm to 4.60mm for ODU). The ODU part accommodates cables 0.02mm smaller at the lower limit. Verify your cable diameter falls within both ranges for interchangeability.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both PHG.0K.303.CLLC35Z and K20K0C-P03LJG0-350S are ROHS3 compliant, REACH unaffected, and classified as EAR99 with identical HTSUS codes.

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

A: LEMO uses chrome plating directly on brass. ODU applies chrome plating over a nickel underplate. Both finishes provide corrosion resistance; the nickel underplate in the ODU variant offers additional protection in harsh environments.

Q: Which part should I choose for high-temperature applications?

A: The LEMO PHG.0K.303.CLLC35Z supports operating temperatures up to 200°C, making it the required choice for high-temperature applications. The ODU part is limited to 120°C maximum.
