Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HEG.0B.309.CLLP is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 9
• Termination Type: Solder Cup
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Front Side Nut
• Fastening Type: Push-Pull
• Ingress Protection: IP68 - Dust Tight, Waterproof
• Shielding: Shielded
• Insert Material: Polyetheretherketone (PEEK)

Compatible Variation Parameters:

• Shell Material: Brass (primary material consistency)
• Contact Finish - Mating: Gold (electrical performance requirement)
• Current Rating: Equal to or greater than 2A
• Operating Temperature Range: Must encompass or exceed -20°C ~ 100°C

The substitute part G80L0C-P09LCC0-0000 (ODU MINI-SNAP® L series) satisfies all mandatory matching parameters and maintains compatibility across all variation parameters, with enhanced current rating (4A) and extended operating temperature range (-40°C ~ 120°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Part: HEG.0B.309.CLLP (LEMO)

The HEG.0B.309.CLLP maintains Active product status with established inventory availability (772 units). This part is suitable for applications requiring the specified operating temperature range (-20°C ~ 100°C) and 2A current capacity. Material flammability rating UL94 V-0 is documented.

Substitute Part: G80L0C-P09LCC0-0000 (ODU MINI-SNAP® L)

The G80L0C-P09LCC0-0000 is qualified as a direct substitute based on complete parameter alignment across all mandatory matching criteria. This part offers:

• Active product status with current inventory (714 units)
• ROHS3 Compliance and REACH Unaffected status
• Enhanced current rating of 4A (exceeds 2A requirement)
• Extended operating temperature range of -40°C ~ 120°C (encompasses primary part range)
• Identical connector configuration, termination, mounting, and shielding specifications
• Moisture Sensitivity Level (MSL) 1 (Unlimited)

Selection between these parts is determined by application-specific requirements regarding temperature extremes, current capacity, and regulatory compliance documentation. Both parts satisfy the core functional and mechanical requirements for 9-position circular connector receptacle applications with solder cup termination and panel mount configuration.

Frequently Asked Questions (FAQ)

Q: What determines if G80L0C-P09LCC0-0000 can substitute for HEG.0B.309.CLLP?

A: Substitution is valid when all mandatory parameters match: 9-position receptacle configuration, female sockets, solder cup termination, panel mount with bulkhead front-side nut, push-pull fastening, IP68 ingress protection, shielding, and PEEK insert material. The ODU part satisfies all these requirements.

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

A: The HEG.0B.309.CLLP features chrome finish on brass shell. The G80L0C-P09LCC0-0000 features chrome over nickel finish on brass shell. Both finishes provide equivalent corrosion resistance and electrical performance for the specified applications.

Q: How do current ratings affect substitution?

A: The HEG.0B.309.CLLP is rated at 2A. The G80L0C-P09LCC0-0000 is rated at 4A. The higher rating of the substitute part is compatible with applications designed for 2A operation, as it represents increased capacity without reducing performance in lower-current applications.

Q: What is the temperature operating range difference?

A: The HEG.0B.309.CLLP operates from -20°C to 100°C. The G80L0C-P09LCC0-0000 operates from -40°C to 120°C. The substitute part's extended range encompasses the primary part's range, making it suitable for applications requiring either temperature specification.

Q: Are both parts available in bulk packaging?

A: Yes. Both the HEG.0B.309.CLLP (772 units) and G80L0C-P09LCC0-0000 (714 units) are available in bulk packaging as new original stock.

Q: What compliance certifications apply to the substitute part?

A: The G80L0C-P09LCC0-0000 is ROHS3 Compliant, REACH Unaffected, and carries MSL 1 (Unlimited) moisture sensitivity rating. The primary part HEG.0B.309.CLLP documents UL94 V-0 material flammability rating.

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

A: Mechanical and electrical interchangeability is confirmed based on matching connector type, position count, termination method, mounting configuration, and fastening mechanism. Physical dimensions and mating interface specifications must be verified against design documentation for specific applications.
