ECA.1B.302.CLL Equivalent & Substitute Parts

Part Overview

The ECA.1B.302.CLL is a 2-position circular connector receptacle manufactured by LEMO, featuring female sockets with solder cup termination. This component is designed for panel mount applications requiring push-pull fastening and shielded signal transmission. The part is currently in active production status with 826 units available in inventory. 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.

Substitute Part Grouping Explanation

Substitution of the ECA.1B.302.CLL is permissible with the ODU part G51LAC-P02LPH0-0000 based on the following alignment of critical parameters:

Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 2
• Termination: Solder Cup
• Fastening type: Push-Pull
• Mounting type: Panel Mount
• Shielding: Shielded
• Shell material: Brass
• Shell finish: Chrome
• Contact finish - mating: Gold
• Ingress protection: IP50 - Dust Protected
• Insert material: Polyetheretherketone (PEEK)
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters: The substitute part operates within a reduced temperature range (-40°C ~ 120°C versus -55°C ~ 250°C) and has a lower current rating (12A versus 15A). These differences must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ECA.1B.302.CLL and G51LAC-P02LPH0-0000 maintain active production status and comply with ROHS3 and REACH requirements. Selection between these parts must be determined by application-specific thermal and current requirements. The LEMO part supports extended temperature operation from -55°C to 250°C and carries a 15A current rating. The ODU substitute operates within -40°C to 120°C and is rated for 12A. Applications requiring the full temperature or current specifications of the primary part cannot use the substitute without design modification. Both parts are classified as MSL 1 (Unlimited) and present no moisture sensitivity constraints for standard storage and handling.

Frequently Asked Questions (FAQ)

Q: Can G51LAC-P02LPH0-0000 be used as a direct replacement for ECA.1B.302.CLL?

A: Substitution is permissible only when application requirements fall within the operating parameters of the ODU part. The substitute operates at -40°C to 120°C and supports 12A maximum current. If your application requires the full -55°C to 250°C range or 15A current capacity of the LEMO part, the substitute is not suitable.

Q: What are the key compatibility factors between these two parts?

A: Both parts share identical connector architecture: 2-position receptacle with female sockets, solder cup termination, push-pull fastening, panel mount configuration, shielded design, brass shell with gold-plated contacts, and PEEK inserts. Both meet IP50 ingress protection and ROHS3 compliance.

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

A: The LEMO part features chrome finish on brass. The ODU part features chrome over nickel on brass. Both finishes provide equivalent corrosion resistance for standard industrial environments.

Q: What is the impact of the 3A current rating difference?

A: The LEMO part is rated for 15A while the ODU substitute is rated for 12A. Applications operating above 12A require the primary LEMO part. For applications at or below 12A, the substitute is electrically compatible.

Q: Are packaging considerations relevant to substitution?

A: The LEMO part is supplied in standard packaging. The ODU substitute is supplied in bulk packaging. Procurement and inventory management processes may require adjustment when switching suppliers.
