Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGA.0B.307.CLAD31Z is determined by the following critical parameters:

• Connector Type & Configuration: Plug with male pins, 7-position, solder cup termination
• Fastening Mechanism: Push-pull fastening system
• Electrical Properties: Gold-plated mating contacts, shielded design
• Environmental Protection: IP50 ingress protection rating
• Termination Method: Solder cup for PCB or cable assembly
• Compliance: ROHS3 compliance and EAR99 classification

The substitute part S20LAC-P07MCC0-320S from ODU meets these core substitution criteria. Both parts share identical connector type, position count, termination method, fastening type, contact finish, shielding, and ingress protection rating. Both are ROHS3 compliant and EAR99 classified.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.0B.307.CLAD31Z and S20LAC-P07MCC0-320S are active production parts with ROHS3 compliance and EAR99 classification. Selection between these parts should be based on the following provided specifications:

FGA.0B.307.CLAD31Z (LEMO) is suitable when:

• Operating temperature range of -55°C to 250°C is required
• The wider upper temperature limit is a design requirement

S20LAC-P07MCC0-320S (ODU) is suitable when:

• Higher current capacity (4A vs 2.5A) is beneficial for the application
• Operating temperature range of -40°C to 120°C meets application requirements
• Strain relief feature is required in the assembly

Both parts satisfy the core functional requirements of a 7-position shielded circular connector plug with solder cup termination, push-pull fastening, and gold-plated contacts.

Frequently Asked Questions (FAQ)

Q: Can S20LAC-P07MCC0-320S directly replace FGA.0B.307.CLAD31Z in existing designs?

A: Direct mechanical and electrical substitution is possible for applications operating within -40°C to 120°C. Applications requiring operation below -40°C or above 120°C must use the FGA.0B.307.CLAD31Z due to its extended temperature range of -55°C to 250°C.

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

A: The primary differences are operating temperature range (LEMO: -55°C to 250°C; ODU: -40°C to 120°C), current rating (LEMO: 2.5A; ODU: 4A), shell finish (LEMO: Chrome; ODU: Chrome over Nickel), and cable opening tolerance (LEMO: 2.30mm to 3.20mm; ODU: 2.00mm to 3.20mm). All other functional parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes, both FGA.0B.307.CLAD31Z and S20LAC-P07MCC0-320S are ROHS3 compliant and EAR99 classified.

Q: What is the significance of the cable opening specifications?

A: Cable opening specifications define the acceptable cable diameter range for proper strain relief and backshell seating. The overlapping range (2.30mm to 3.20mm) ensures compatibility for cables within this specification window.

Q: Does the higher current rating of the ODU part affect compatibility?

A: No. The ODU part's 4A rating is higher than the LEMO part's 2.5A rating, making it suitable for applications requiring either rating. Current rating compatibility is unidirectional—a higher-rated part can substitute for a lower-rated part in the same application.
