Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.1K.310.CLLC45Z is determined by the following critical parameters:

• Connector Configuration: Receptacle type with female sockets and 10-position contact arrangement
• Termination Method: Solder cup termination for PCB or cable assembly integration
• Fastening Mechanism: Push-pull coupling system for secure mating and unmating
• Environmental Sealing: Shielded construction with IP68 waterproof rating minimum
• Electrical Performance: Current rating of 2.5A or greater to support equivalent load capacity
• Material Compatibility: PEEK insert material with gold-plated mating contacts
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The substitute part K21K0C-P10LCC0-450S meets these core substitution criteria across all mandatory electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.1K.310.CLLC45Z and K21K0C-P10LCC0-450S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. The ODU substitute provides higher current capacity (4A versus 2.5A), making it suitable for applications with increased power delivery requirements. The LEMO part maintains a wider operating temperature range (-55°C to 200°C), which is critical for extreme environment applications. Cable opening dimensions are compatible within tolerance, with the ODU part accommodating slightly smaller cable diameters (4.00mm minimum versus 4.10mm). Both connectors feature identical push-pull fastening, shielded construction, and PEEK insert material, ensuring mechanical and environmental compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can K21K0C-P10LCC0-450S directly replace PHG.1K.310.CLLC45Z in all applications?

A: Direct substitution is valid for applications operating within the ODU part's temperature range (-40°C to 120°C) and current requirements up to 4A. Applications requiring operation below -40°C or above 120°C require the LEMO part's extended temperature range.

Q: What are the cable opening compatibility considerations?

A: The cable opening ranges overlap substantially (4.10mm to 4.50mm for LEMO; 4.00mm to 4.50mm for ODU). Cables sized between 4.10mm and 4.50mm are compatible with both connectors. Cables between 4.00mm and 4.10mm are compatible only with the ODU part.

Q: Are the solder cup terminations identical between these parts?

A: Both parts feature solder cup termination compatible with standard PCB assembly and cable soldering processes. No modification to assembly procedures is required when substituting between these connectors.

Q: Do both parts meet the same environmental sealing standards?

A: Both connectors achieve IP68 waterproof rating. The LEMO part is rated IP66/IP68, while the ODU part is rated IP68. Both are suitable for dust-tight and waterproof applications.

Q: What is the inventory status for each part?

A: PHG.1K.310.CLLC45Z has 701 units in stock. K21K0C-P10LCC0-450S has 1119 units in stock. Both parts are available for immediate procurement.
