Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EGA.1B.304.CLL is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 4
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Rear Side Nut
• Termination: Solder Cup
• Fastening Type: Push-Pull
• Shielding: Shielded
• Ingress Protection: IP50 - Dust Protected
• Insert Material: Polyetheretherketone (PEEK)

Allowable Variation Parameters:

• Shell Size - Insert: Different shell sizes permitted if mechanical fit accommodates panel mount configuration
• Current Rating: Substitute must meet or exceed 10A requirement
• Operating Temperature Range: Substitute must encompass or exceed -55°C ~ 250°C range
• Contact Finish Thickness: Variations permitted within industry standards
• Shell Material and Finish: Variations permitted (brass with chrome or chrome over nickel acceptable)
• Contact Material: Variations permitted (bronze or brass acceptable)

The substitute part G11LAC-P04LJG0-0000 from ODU meets all mandatory matching parameters and qualifies as an equivalent component.

Parameter Comparison

Engineering Selection Recommendations

Both the EGA.1B.304.CLL and G11LAC-P04LJG0-0000 maintain Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory alignment for current and future applications.

The EGA.1B.304.CLL provides extended operating temperature capability (-55°C ~ 250°C) and higher current rating (10A), making it the primary selection for high-temperature or high-current applications.

The G11LAC-P04LJG0-0000 operates within -40°C ~ 120°C and supports 7.5A current rating. This substitute is suitable for applications where the operating temperature and current requirements fall within these specified limits. The ODU MINI-SNAP® L series connector maintains identical mechanical and electrical interface characteristics, enabling direct substitution in panel mount configurations with push-pull fastening.

Selection between these parts should be based on application-specific temperature and current requirements. Both parts satisfy identical functional requirements for 4-position shielded circular connector receptacles with solder cup termination and IP50 ingress protection.

Frequently Asked Questions (FAQ)

Q: Can G11LAC-P04LJG0-0000 be used as a direct replacement for EGA.1B.304.CLL?

A: Yes, within application-specific constraints. The G11LAC-P04LJG0-0000 is mechanically and electrically compatible for panel mount applications requiring 4-position shielded circular connectors with solder cup termination. However, verify that your application operates within -40°C ~ 120°C temperature range and does not exceed 7.5A current draw. If your application requires the extended temperature range (-55°C ~ 250°C) or 10A current rating of the EGA.1B.304.CLL, the substitute is not appropriate.

Q: What are the key differences between these two connectors?

A: The primary differences are operating temperature range and current rating. The EGA.1B.304.CLL supports -55°C ~ 250°C and 10A, while the G11LAC-P04LJG0-0000 supports -40°C ~ 120°C and 7.5A. Shell finish differs slightly (chrome versus chrome over nickel), and contact material varies (bronze versus brass). All other functional and mechanical parameters are identical.

Q: Are both connectors RoHS compliant?

A: Yes, both the EGA.1B.304.CLL and G11LAC-P04LJG0-0000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the shell size difference (304 versus 1)?

A: Shell size designations are manufacturer-specific nomenclature. The EGA.1B.304.CLL uses LEMO's 304 designation, while the G11LAC-P04LJG0-0000 uses ODU's size 1 designation. Despite different naming conventions, both connectors are mechanically compatible for identical panel mount applications with bulkhead rear side nut fastening.

Q: Can these connectors be used interchangeably in existing designs?

A: Mechanical and electrical interchangeability is confirmed for the connector interface. However, application-specific validation is required to confirm that operating temperature and current requirements fall within the G11LAC-P04LJG0-0000 specifications. If your design operates at temperatures below -40°C or above 120°C, or requires current exceeding 7.5A, the EGA.1B.304.CLL is the required component.
