Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.1K.314.CLLC45Z is determined by the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets and 14-position count
• Termination Method: Solder cup termination for PCB integration
• Fastening Mechanism: Push-pull coupling system
• Shielding Requirement: Shielded construction for EMI protection
• Ingress Protection: IP68 waterproof rating or equivalent
• Electrical Performance: Current rating and operating temperature range compatibility
• Material & Compliance: ROHS3 compliance and PEEK insert material

The substitute part K21K0C-P14LCC0-450S from ODU meets the core functional requirements of a 14-position shielded receptacle with solder cup termination and push-pull fastening. Both parts are ROHS3 compliant and feature PEEK inserts with shielded construction suitable for industrial and waterproof applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.1K.314.CLLC45Z and K21K0C-P14LCC0-450S are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. Selection between these parts should be based on the following criteria:

PHG.1K.314.CLLC45Z (LEMO) is appropriate when:

• Extended operating temperature range of -55°C to 200°C is required
• IP66/IP68 ingress protection specification is mandated
• 2A current rating meets application requirements
• LEMO series compatibility is specified in system design

K21K0C-P14LCC0-450S (ODU MINI-SNAP® K) is appropriate when:

• Higher current capacity of 4A is beneficial
• Operating temperature range of -40°C to 120°C is acceptable
• IP68 waterproof rating satisfies application needs
• ODU connector ecosystem integration is preferred
• Strain relief feature is advantageous for cable management

Both connectors feature identical core specifications: 14-position configuration, solder cup termination, push-pull fastening, shielded construction, brass shells with gold-plated contacts, and PEEK inserts. Cable opening dimensions are compatible within tolerance ranges.

Frequently Asked Questions (FAQ)

Q: Can K21K0C-P14LCC0-450S directly replace PHG.1K.314.CLLC45Z in all applications?

A: Direct replacement is possible when the application operating temperature does not exceed 120°C and does not fall below -40°C. The PHG.1K.314.CLLC45Z supports extended temperature operation to -55°C and 200°C. Verify temperature requirements before substitution.

Q: What are the key compatibility factors between these two connectors?

A: Both connectors share identical core specifications: 14-position receptacle configuration, female sockets, solder cup termination, push-pull fastening, shielded construction, and PEEK inserts. Cable opening dimensions are compatible. Both are ROHS3 compliant and rated for waterproof applications.

Q: Does the higher current rating of K21K0C-P14LCC0-450S affect compatibility?

A: No. The 4A rating of the ODU connector exceeds the 2A requirement of the LEMO connector. Higher current capacity does not create incompatibility; it provides additional margin for applications with higher current demands.

Q: Are there mechanical differences that affect mating?

A: Both connectors use push-pull fastening with shielded, free-hanging in-line mounting. Cable opening ranges are compatible: LEMO 4.10-4.50mm versus ODU 4.00-4.50mm. Verify cable diameter falls within both ranges for seamless substitution.

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

A: LEMO uses chrome finish; ODU uses chrome over nickel. Both finishes provide corrosion resistance suitable for IP68 waterproof applications. The nickel underplate in the ODU connector provides additional corrosion protection in harsh environments.

Q: Are both parts suitable for industrial and medical applications?

A: Both connectors are ROHS3 compliant and REACH unaffected. The ODU connector explicitly lists industrial, medical, military, and testing equipment applications. The LEMO connector is active production with equivalent compliance certifications, making it suitable for similar application categories.
