EGG.0K.309.CLL Equivalent & Substitute Parts

Part Overview

The EGG.0K.309.CLL is a 9-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination. This connector is designed for panel mount applications with bulkhead rear side nut fastening and operates across an extended temperature range of -55°C to 200°C. The part is actively produced and maintains ROHS3 compliance with IP66/IP68 ingress protection rating.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent connector configurations that maintain functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

The substitute part G10K0C-P09LCC0-0000 (ODU MINI-SNAP® K series) is identified as functionally equivalent based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Termination method: Solder Cup
• Fastening type: Push-Pull
• Mounting type: Panel Mount with Bulkhead - Rear Side Nut
• Shielding: Shielded
• Contact finish: Gold
• Shell material: Brass
• Insert material: PEEK
• Ingress protection: IP68 (exceeds IP66/IP68 requirement)
• RoHS compliance: ROHS3 Compliant
• Packaging: Bulk

Differing Parameters:

• Shell size insert designation differs (309 vs. 0)
• Current rating: 2A vs. 4A
• Operating temperature range: -55°C ~ 200°C vs. -40°C ~ 120°C
• Shell finish: Chrome vs. Chrome over Nickel
• Contact material: Bronze vs. Brass

The substitute part provides equivalent electrical and mechanical interface characteristics for 9-position solder cup receptacle applications with push-pull fastening and shielded construction.

Parameter Comparison

Engineering Selection Recommendations

Both the EGG.0K.309.CLL and G10K0C-P09LCC0-0000 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The primary selection criterion is operating temperature range. The LEMO EGG.0K.309.CLL supports -55°C to 200°C operation, while the ODU substitute operates within -40°C to 120°C. Applications requiring extended low-temperature operation below -40°C or high-temperature operation above 120°C must use the LEMO part.

The ODU substitute provides higher current capacity (4A vs. 2A), which may accommodate higher power applications within its temperature range. Both connectors maintain equivalent mechanical interface characteristics, shielding, and gold-plated contact finish for reliable mating cycles.

Frequently Asked Questions (FAQ)

Q: Can G10K0C-P09LCC0-0000 be used as a direct replacement for EGG.0K.309.CLL?

A: Mechanical and electrical interface compatibility exists for applications operating within -40°C to 120°C. Applications requiring the extended temperature range of the LEMO part (-55°C to 200°C) require the original part number.

Q: What is the significance of the different shell size designations (309 vs. 0)?

A: Shell size designations identify the physical connector envelope. The different designations indicate these are distinct connector families from different manufacturers, though both accommodate 9-position solder cup configurations with equivalent mating interfaces.

Q: Does the higher current rating of the ODU part affect compatibility?

A: The 4A rating of the ODU substitute exceeds the 2A requirement of the LEMO part. Higher current capacity does not create incompatibility; it indicates the substitute can handle equal or greater power levels within its operating temperature range.

Q: Are both parts suitable for industrial applications?

A: Both parts are active products with ROHS3 compliance and IP68 ingress protection. The ODU part explicitly lists industrial applications. Selection depends on specific temperature and current requirements of the application.

Q: What is the difference between IP66/IP68 and IP68 ratings?

A: The LEMO part specifies IP66/IP68 protection, while the ODU substitute specifies IP68. IP68 represents the higher protection level within this range, indicating complete dust tightness and waterproof operation under continuous immersion conditions.
