PHG.0K.302.CLLC45Z Equivalent & Substitute Parts

Part Overview

The PHG.0K.302.CLLC45Z is a 2-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination. This connector is classified as a push-pull fastening type with shielded construction, designed for free-hanging in-line mounting applications. The part is currently active in production with 896 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary connector becomes unavailable or when design requirements permit alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PHG.0K.302.CLLC45Z is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with female sockets
• Number of positions: 2
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding configuration: Shielded
• Insert material: Polyetheretherketone (PEEK)
• Mounting configuration: Free hanging in-line
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass construction
• Regulatory compliance: ROHS3 compliant, REACH unaffected

Allowable Parameter Variations: Substitute parts may differ in shell finish specification (chrome versus chrome over nickel), current rating capacity, operating temperature range, and ingress protection rating, provided the substitute maintains or exceeds the functional requirements of the application. Cable opening dimensions must remain within compatible ranges to ensure proper strain relief and backshell fit.

The identified substitute K20K0C-P02LJG0-450S from ODU meets these substitution criteria through equivalent connector architecture, identical position count, matching termination and fastening systems, and compatible mechanical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.302.CLLC45Z and K20K0C-P02LJG0-450S maintain active production status and full regulatory compliance under ROHS3 and REACH standards. Selection between these parts should be based on application-specific requirements:

The PHG.0K.302.CLLC45Z supports extended operating temperature range (-55°C to 200°C) and higher current capacity (10A), making it suitable for high-temperature industrial and aerospace applications. The K20K0C-P02LJG0-450S operates within -40°C to 120°C and carries 7.5A current rating, appropriate for standard industrial, medical, military, and testing equipment environments. Both connectors provide IP68 waterproof protection; the PHG.0K.302.CLLC45Z additionally specifies IP66 dust-tight rating. The ODU substitute includes integrated strain relief features, while the LEMO original includes backshell provision. Cable opening dimensions are compatible across both parts within the specified ranges.

Frequently Asked Questions (FAQ)

Q: Can the K20K0C-P02LJG0-450S directly replace the PHG.0K.302.CLLC45Z in all applications?

A: Direct substitution is valid when application requirements fall within the ODU part's operating parameters: operating temperature range of -40°C to 120°C and current load not exceeding 7.5A. Applications requiring extended temperature operation beyond 120°C or current exceeding 7.5A require the LEMO original specification.

Q: What are the mechanical compatibility considerations?

A: Both connectors feature identical 2-position push-pull receptacle architecture with solder cup termination and PEEK inserts. Cable opening ranges overlap (4.10mm to 4.50mm for LEMO; 4.00mm to 4.50mm for ODU), ensuring compatible strain relief and backshell integration. The ODU part includes integrated strain relief, while the LEMO part specifies backshell provision.

Q: Are there differences in environmental protection ratings?

A: The PHG.0K.302.CLLC45Z specifies IP66/IP68 protection (dust-tight and waterproof). The K20K0C-P02LJG0-450S specifies IP68 protection (waterproof). Both provide equivalent waterproof sealing; the LEMO part additionally certifies dust-tight performance.

Q: What is the significance of shell finish differences?

A: The LEMO part uses chrome plating directly on brass. The ODU part uses chrome over nickel plating on brass. Both finishes provide corrosion resistance; the nickel underplate in the ODU part offers additional corrosion barrier properties in certain chemical environments.

Q: Are both parts available in equivalent packaging quantities?

A: The PHG.0K.302.CLLC45Z is available in standard packaging with 896 units in stock. The K20K0C-P02LJG0-450S is supplied in bulk packaging with 862 units in stock. Packaging format does not affect electrical or mechanical compatibility.

Q: What regulatory certifications apply to both parts?

A: Both connectors are ROHS3 compliant and REACH unaffected, meeting current European Union environmental and chemical safety requirements. Both carry ECCN classification EAR99 and HTSUS code 8536.69.4020.
