Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECA.1B.308.CLL is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Receptacle with female sockets
• Number of positions: 8
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Mounting configuration: Panel mount
• Shielding: Shielded design
• Insert material: PEEK

Secondary Compatibility Factors:

• Shell material: Brass construction
• Contact finish: Gold plating
• Ingress protection rating: IP50 or equivalent
• Regulatory compliance: ROHS3 and REACH status

The substitute part G51LAC-P08LFG0-0000 from ODU satisfies all primary matching criteria and maintains compatibility across secondary factors, enabling direct functional substitution in applications requiring 8-position shielded circular connectors with solder cup termination.

Parameter Comparison

Engineering Selection Recommendations

Both the ECA.1B.308.CLL and G51LAC-P08LFG0-0000 maintain active product status and full compliance with ROHS3 and REACH regulatory requirements. Selection between these parts should be based on application-specific operating conditions:

The ECA.1B.308.CLL supports an extended operating temperature range of -55°C to 250°C, making it suitable for applications requiring extreme temperature performance. The G51LAC-P08LFG0-0000 operates within -40°C to 120°C and provides a higher current rating of 7.5A compared to the 5A rating of the primary part. Both connectors employ identical termination, fastening, and shielding architectures, ensuring functional interchangeability in standard applications where temperature and current requirements fall within the overlapping operational envelope.

Frequently Asked Questions (FAQ)

Q: Can the G51LAC-P08LFG0-0000 directly replace the ECA.1B.308.CLL in all applications?

A: Direct substitution is valid for applications operating within the temperature range of -40°C to 120°C and requiring current levels up to 7.5A. Applications requiring operation below -40°C or above 120°C must retain the ECA.1B.308.CLL due to its extended temperature specification.

Q: What are the key compatibility factors for these substitute parts?

A: Both connectors share identical specifications for connector type (receptacle, female sockets), position count (8), termination method (solder cup), fastening mechanism (push-pull), mounting configuration (panel mount), shielding (shielded), insert material (PEEK), and ingress protection rating (IP50). These parameters establish functional equivalence.

Q: Are there differences in shell finish between these parts?

A: The ECA.1B.308.CLL features chrome plating, while the G51LAC-P08LFG0-0000 uses chrome over nickel. Both finishes provide equivalent corrosion resistance and contact reliability for the specified applications.

Q: What is the significance of the current rating difference?

A: The G51LAC-P08LFG0-0000 supports 7.5A versus the 5A rating of the ECA.1B.308.CLL. Applications requiring current levels between 5A and 7.5A may utilize the substitute part. Applications limited to 5A or below can use either connector.

Q: Do both parts meet the same regulatory standards?

A: Both connectors are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for environmental and hazardous substance compliance.
