PHG.0K.309.CLLC45 Equivalent & Substitute Parts

Part Overview

The PHG.0K.309.CLLC45 is a 9-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination and push-pull fastening. This connector is classified as Active product status with 1024 units in stock. The part is designed for applications requiring shielded, waterproof connectivity with gold-plated mating contacts and operates across an extended temperature range of -55°C to 200°C. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate qualified alternatives meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part K10K0C-P09LCC0-4500 (ODU MINI-SNAP® K series) qualifies as an equivalent based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Termination method: Solder Cup
• Fastening mechanism: Push-Pull
• Primary shell material: Brass
• Contact finish: Gold
• Shielding: Shielded
• Insert material: Polyetheretherketone (PEEK)
• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH unaffected status
• ECCN: EAR99

Allowable Parameter Variations: The substitute part exhibits differences in shell finish (Chrome over Nickel vs. Chrome), current rating (4A vs. 2A), operating temperature range (-40°C ~ 120°C vs. -55°C ~ 200°C), and cable opening tolerance (0.157" ~ 0.177" vs. 0.161" ~ 0.177"). These variations remain within acceptable substitution criteria for circular connector receptacles in this category.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.0K.309.CLLC45 and K10K0C-P09LCC0-4500 maintain Active product status with full ROHS3 compliance and REACH unaffected certification. Selection between these parts should be based on application-specific requirements:

The PHG.0K.309.CLLC45 is suitable for applications requiring the extended operating temperature range of -55°C to 200°C and the dual ingress protection rating of IP66/IP68. The 2A current rating accommodates standard signal and low-power applications.

The K10K0C-P09LCC0-4500 provides higher current capacity at 4A and operates within the -40°C to 120°C range, making it appropriate for industrial, medical, military, and testing equipment applications where extended low-temperature performance is not critical. The chrome-over-nickel finish provides enhanced corrosion resistance in certain environmental conditions.

Both parts share identical core specifications: 9-position female socket receptacles with solder cup termination, push-pull fastening, brass shells with gold-plated contacts, PEEK inserts, and shielded construction. Regulatory compliance is equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can K10K0C-P09LCC0-4500 be used as a direct replacement for PHG.0K.309.CLLC45?

A: The K10K0C-P09LCC0-4500 qualifies as a substitute based on matching connector type, position count, termination method, fastening mechanism, and material specifications. However, the operating temperature range differs (-40°C to 120°C vs. -55°C to 200°C). Substitution is valid only if the application does not require operation below -40°C or above 120°C.

Q: What are the key compatibility factors for these circular connector receptacles?

A: Critical compatibility parameters include: 9-position configuration, female socket type, solder cup termination, push-pull fastening, shielded design, and gold-plated mating contacts. Both parts meet these specifications identically.

Q: How do the current ratings differ between these parts?

A: The PHG.0K.309.CLLC45 is rated for 2A, while the K10K0C-P09LCC0-4500 is rated for 4A. The higher rating of the substitute part does not restrict its use in 2A applications; however, the lower-rated part cannot be substituted in circuits requiring 4A capacity.

Q: Are there differences in environmental sealing between these connectors?

A: The PHG.0K.309.CLLC45 carries dual IP66/IP68 ratings. The K10K0C-P09LCC0-4500 carries IP68 rating. Both provide dust-tight and waterproof protection suitable for harsh environments.

Q: What packaging considerations apply to these parts?

A: The PHG.0K.309.CLLC45 is available in standard packaging with 1024 units in stock. The K10K0C-P09LCC0-4500 is supplied in bulk packaging with 726 units in stock. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both parts comply with regulatory requirements?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Regulatory compliance is equivalent for both options.
