Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1B.302.CLAD42Z is determined by the following critical parameters:

• Connector type and gender (Plug, Male Pins)
• Number of positions (2)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Shielding requirement (Shielded)
• Contact finish (Gold plating)
• Ingress protection rating (IP50 minimum)
• Insert material (PEEK)
• Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The substitute part S21L0C-P02MPH0-420S from ODU meets these core substitution criteria. Both parts share identical connector topology, termination approach, and material specifications for the insert. Differences in shell size designation, current rating, and operating temperature range are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1B.302.CLAD42Z and S21L0C-P02MPH0-420S are active production parts with ROHS3 compliance and REACH Unaffected status. Selection between these parts depends on application-specific requirements:

The FGG.1B.302.CLAD42Z supports higher current capacity (15A versus 12A) and extended operating temperature range (-55°C to 250°C versus -40°C to 120°C). Applications requiring operation at elevated temperatures or higher current loads should specify the LEMO part.

The S21L0C-P02MPH0-420S from ODU includes integrated strain relief and is qualified for industrial, medical, military, and testing equipment applications. This part is suitable for applications within its specified temperature and current parameters.

Both parts maintain identical connector topology, shielding, and contact finish specifications, ensuring functional compatibility in push-pull circular connector applications.

Frequently Asked Questions (FAQ)

Q: Can the S21L0C-P02MPH0-420S directly replace the FGG.1B.302.CLAD42Z?

A: Direct replacement is possible only if the application operates within the ODU part's specifications: maximum 12A current, operating temperature range -40°C to 120°C, and cable opening tolerance 3.00mm to 4.20mm. Both parts share identical connector type, position count, termination method, and shielding characteristics.

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

A: The primary differences are current rating (15A versus 12A), operating temperature range (-55°C to 250°C versus -40°C to 120°C), shell finish (Chrome versus Chrome over Nickel), and cable opening tolerance. The ODU part includes strain relief as an additional feature.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the FGG.1B.302.CLAD42Z and S21L0C-P02MPH0-420S are ROHS3 compliant and REACH Unaffected.

Q: What is the cable opening tolerance for each part?

A: The FGG.1B.302.CLAD42Z accepts cable diameters of 0.122" to 0.165" (3.10mm to 4.20mm). The S21L0C-P02MPH0-420S accepts 0.118" to 0.165" (3.00mm to 4.20mm). Verify cable diameter compatibility before selection.

Q: Which part should be selected for high-temperature applications?

A: The FGG.1B.302.CLAD42Z is rated for -55°C to 250°C and is the appropriate choice for applications exceeding 120°C. The S21L0C-P02MPH0-420S is limited to -40°C to 120°C.
