ECA.1B.306.CLL Equivalent & Substitute Parts

Part Overview

The ECA.1B.306.CLL is a 6-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination. This connector is designed for panel mount applications with push-pull fastening and operates across a wide temperature range of -55°C to 250°C. The part is currently active in production with 1151 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component substitution within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECA.1B.306.CLL is determined by strict alignment of the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Number of positions (6)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Mounting configuration (Panel Mount)
• Shielding requirement (Shielded)
• Contact finish specification (Gold plating on mating surfaces)
• Ingress protection rating (IP50 minimum)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The substitute part G51LAC-P06LFG0-0000 from ODU meets these core substitution criteria. Both parts are 6-position shielded receptacles with female sockets, solder cup termination, push-pull fastening, and panel mount configuration. Both achieve IP50 ingress protection and maintain ROHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Both the ECA.1B.306.CLL and G51LAC-P06LFG0-0000 are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific temperature and current requirements.

The ECA.1B.306.CLL supports an extended operating temperature range of -55°C to 250°C, making it suitable for high-temperature applications. The G51LAC-P06LFG0-0000 operates within -40°C to 120°C, appropriate for standard industrial, medical, military, and testing equipment environments. The ODU substitute provides a marginally higher current rating of 7.5A compared to the LEMO part's 7A rating.

Both connectors maintain identical core electrical and mechanical specifications: 6-position configuration, solder cup termination, push-pull fastening, shielded design, gold-plated mating contacts, and IP50 ingress protection. Component selection should be based on the specific thermal and current demands of the target application.

Frequently Asked Questions (FAQ)

Q: Can G51LAC-P06LFG0-0000 be used as a direct replacement for ECA.1B.306.CLL?

A: Yes, within the operating temperature range of -40°C to 120°C. Both parts share identical connector type, position count, termination method, fastening mechanism, and shielding configuration. If your application requires operation below -40°C or above 120°C, the ECA.1B.306.CLL is required.

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

A: The primary differences are operating temperature range (ECA.1B.306.CLL: -55°C to 250°C; G51LAC-P06LFG0-0000: -40°C to 120°C), current rating (7A vs. 7.5A), and shell finish (Chrome vs. Chrome over Nickel). All other electrical and mechanical parameters are equivalent.

Q: Are both parts RoHS compliant?

A: Yes, both ECA.1B.306.CLL and G51LAC-P06LFG0-0000 are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Do both connectors support the same current capacity?

A: The ECA.1B.306.CLL is rated for 7A, while the G51LAC-P06LFG0-0000 is rated for 7.5A. Both are suitable for applications requiring up to 7A continuous current.

Q: What ingress protection rating do these connectors provide?

A: Both connectors provide IP50 ingress protection, classified as dust protected. This rating is suitable for industrial and general-purpose applications.
