Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.0K.303.CLLC45Z is determined by the following critical parameters:

• Connector Type: Receptacle with female sockets
• Number of Positions: 3-position configuration
• Termination Method: Solder cup
• Fastening Mechanism: Push-pull coupling
• Ingress Protection: IP66/IP68 or equivalent waterproof rating
• Current Capacity: Minimum 7.5A (PHG.0K.303.CLLC45Z rated at 8A)
• Cable Opening Range: Overlap within 4.00mm to 4.50mm
• Compliance: ROHS3 compliant, REACH unaffected

The substitute part K20K0C-P03LJG0-450S meets these core criteria, enabling functional equivalence in applications where the specified parameters are compatible.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.303.CLLC45Z and K20K0C-P03LJG0-450S are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

The PHG.0K.303.CLLC45Z supports extended operating temperatures (-55°C to 200°C) and higher current capacity (8A), making it suitable for high-temperature or high-power applications. The K20K0C-P03LJG0-450S operates within -40°C to 120°C with 7.5A current rating and includes integrated strain relief features. Both connectors provide IP68 waterproof protection and solder cup termination with push-pull fastening. Cable opening specifications overlap within the 4.00mm to 4.50mm range, ensuring mechanical compatibility in most installations.

Frequently Asked Questions (FAQ)

Q: Can K20K0C-P03LJG0-450S replace PHG.0K.303.CLLC45Z in all applications?

A: Substitution is valid when application operating temperature does not exceed 120°C and current requirements do not exceed 7.5A. The PHG.0K.303.CLLC45Z is required for applications exceeding these parameters.

Q: What are the key differences between these connectors?

A: Operating temperature range, current rating, and shell finish differ. The PHG.0K.303.CLLC45Z operates to 200°C with 8A capacity and chrome finish. The K20K0C-P03LJG0-450S operates to 120°C with 7.5A capacity, chrome over nickel finish, and includes strain relief.

Q: Are both connectors compatible with the same mating plugs?

A: Both connectors are 3-position receptacles with push-pull fastening and identical contact finish (gold). Mechanical compatibility depends on plug design and shell size specifications. Verify mating plug compatibility with connector series documentation.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PHG.0K.303.CLLC45Z and K20K0C-P03LJG0-450S are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS classifications.

Q: What is the significance of cable opening specifications?

A: Cable opening defines the acceptable cable diameter range for proper strain relief and sealing. PHG.0K.303.CLLC45Z accepts 4.10mm to 4.50mm; K20K0C-P03LJG0-450S accepts 4.00mm to 4.50mm. Verify cable diameter falls within the specified range for your selected connector.
