Key Parameters

Substitute Part Grouping Explanation

Substitution of the PHG.1K.304.CLLC65Z is evaluated based on the following critical parameters that must align for functional compatibility:

Mandatory Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 4
• Termination method: Solder Cup
• Fastening mechanism: Push-Pull
• Mounting configuration: Free Hanging (In-Line)
• Shielding requirement: Shielded
• Insert material: Polyetheretherketone (PEEK)
• Contact finish: Gold plating on mating surfaces

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed 10A requirement
• Operating temperature: Substitute must cover the required operating range or a subset thereof
• Ingress protection: Substitute must meet IP68 or equivalent sealing specification
• Shell material and finish: Brass construction with appropriate plating acceptable
• Cable opening tolerance: Must accommodate 6.10mm ~ 6.50mm cable diameter range

The ODU MINI-SNAP® K series part K21K0C-P04LJG0-650S meets the mandatory matching parameters for 4-position, female socket, solder cup receptacles with push-pull fastening and shielded construction.

Parameter Comparison

Engineering Selection Recommendations

Both the PHG.1K.304.CLLC65Z and K21K0C-P04LJG0-650S are ROHS3 compliant, active production parts with REACH unaffected status and EAR99 export classification. Selection between these parts should be based on the following criteria:

PHG.1K.304.CLLC65Z (LEMO) is preferred when:

• Application requires current capacity of 10A
• Operating temperature range of -55°C to 200°C is required
• Higher temperature performance is critical to system design

K21K0C-P04LJG0-650S (ODU MINI-SNAP® K) is acceptable when:

• Application current requirement does not exceed 7.5A
• Operating temperature range of -40°C to 120°C is sufficient
• Industrial, medical, military, or testing equipment applications are specified
• Strain relief feature is beneficial to the assembly design

Both parts feature identical connector topology, termination method, fastening mechanism, and shielding configuration, ensuring mechanical and electrical interface compatibility within their respective rated parameters.

Frequently Asked Questions (FAQ)

Q: Can the K21K0C-P04LJG0-650S be used as a direct replacement for the PHG.1K.304.CLLC65Z?

A: Mechanical and electrical interface compatibility is confirmed. However, the substitute part has lower current rating (7.5A vs. 10A) and narrower operating temperature range (-40°C to 120°C vs. -55°C to 200°C). Substitution is permissible only if the application requirements fall within the substitute part's specifications.

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

A: The critical parameters are: 4-position configuration, female socket type, solder cup termination, push-pull fastening, free-hanging mounting, shielded construction, and PEEK insert material. Both parts match these specifications.

Q: Are there differences in cable opening tolerances between these parts?

A: The PHG.1K.304.CLLC65Z specifies 0.240" ~ 0.256" (6.10mm ~ 6.50mm), while the K21K0C-P04LJG0-650S specifies 0.236" ~ 0.256" (6.00mm ~ 6.50mm). The tolerance ranges overlap, permitting cable compatibility within the overlapping range of 6.10mm ~ 6.50mm.

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

A: The PHG.1K.304.CLLC65Z is rated IP66/IP68, while the K21K0C-P04LJG0-650S is rated IP68. Both meet IP68 waterproof and dust-tight requirements. The LEMO part additionally specifies IP66 compliance.

Q: What is the difference in shell material plating between these parts?

A: The PHG.1K.304.CLLC65Z uses brass with chrome plating. The K21K0C-P04LJG0-650S uses brass with chrome over nickel plating. Both provide corrosion resistance and electrical conductivity suitable for shielded connector applications.

Q: Are both parts available in active production?

A: Yes. The PHG.1K.304.CLLC65Z has 1056 units in stock, and the K21K0C-P04LJG0-650S has 1033 units in stock. Both parts maintain active product status.
