Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECG.00.303.CLL is determined by alignment across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 3
• Termination Type: Solder Cup
• Mounting Type: Panel Mount
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Ingress Protection: IP50 - Dust Protected
• Insert Material: Polyetheretherketone (PEEK)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Shell Material: Brass (primary material consistency maintained)
• Shell Finish: Chrome or Chrome over Nickel (both provide corrosion protection)
• Current Rating: 3A minimum (substitute may exceed this specification)
• Operating Temperature Range: Substitute range must encompass or exceed the minimum operational envelope
• Contact Material: Bronze or Brass (both provide electrical conductivity and durability)

The substitute part G5CL0C-P03LCC0-0000 from ODU meets all mandatory matching parameters and operates within allowable variation ranges for shell finish and current rating specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (ECG.00.303.CLL): The ECG.00.303.CLL is recommended for applications requiring the full operating temperature range of -55°C to 250°C. This part is actively stocked with 1,027 units available and maintains ROHS3 compliance and REACH unaffected status. The part is suitable for high-temperature industrial applications and environments with extended thermal cycling requirements.

Substitute Part Selection (G5CL0C-P03LCC0-0000): The G5CL0C-P03LCC0-0000 is suitable for applications operating within the -40°C to 120°C temperature range. This substitute provides equivalent electrical and mechanical functionality with a higher current rating of 4A, offering additional margin for applications with moderate current demands. The part is actively stocked with 787 units available and maintains identical RoHS3 compliance and REACH unaffected status.

Selection Criteria:

• Use ECG.00.303.CLL when operating temperatures below -40°C or above 120°C are required
• Use G5CL0C-P03LCC0-0000 when operating within -40°C to 120°C and higher current capacity is beneficial
• Both parts are suitable for industrial, medical, military, and testing equipment applications
• Both parts maintain identical compliance certifications and regulatory status

Frequently Asked Questions (FAQ)

Q: Can the G5CL0C-P03LCC0-0000 be used as a direct replacement for the ECG.00.303.CLL?

A: The G5CL0C-P03LCC0-0000 is functionally equivalent for applications operating within the -40°C to 120°C temperature range. Both parts share identical connector type, position count, termination method, mounting configuration, and fastening mechanism. The substitute part exceeds the current rating specification and maintains equivalent ingress protection and compliance certifications. Applications requiring operation outside the -40°C to 120°C range require the primary part.

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

A: The primary differences are operating temperature range and current rating. The ECG.00.303.CLL operates from -55°C to 250°C with a 3A current rating, while the G5CL0C-P03LCC0-0000 operates from -40°C to 120°C with a 4A current rating. Shell finish differs slightly (Chrome versus Chrome over Nickel), and contact material differs (Bronze versus Brass). These differences do not affect functional compatibility within the specified temperature envelope of the substitute part.

Q: Are both parts RoHS compliant?

A: Yes, both the ECG.00.303.CLL and G5CL0C-P03LCC0-0000 are ROHS3 compliant and REACH unaffected. Both parts carry identical regulatory classification codes (ECCN: EAR99, HTSUS: 8536.69.4020).

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

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or use.

Q: Can these parts be used in medical or military applications?

A: Both parts are suitable for medical, military, and testing equipment applications. The ECG.00.303.CLL is recommended for military applications requiring extended temperature ranges. The G5CL0C-P03LCC0-0000 is suitable for medical and military applications operating within the -40°C to 120°C envelope.

Q: What is the difference between solder cup and other termination types?

A: Solder cup termination allows direct soldering of cable conductors into the connector receptacle, providing a permanent mechanical and electrical connection. Both parts utilize this termination method, ensuring compatibility with identical assembly and integration procedures.

Q: Are there any differences in panel mounting between these parts?

A: Both parts are panel mount connectors with push-pull fastening. The ECG.00.303.CLL features front and rear side nut mounting, while the G5CL0C-P03LCC0-0000 features bulkhead front or rear side nut mounting. Both configurations provide secure panel integration.
