Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1K.302.CLAC45Z is determined by the following critical parameters:

• Connector Configuration: 2-position male plug with solder cup termination
• Fastening Mechanism: Push-pull coupling system
• Electrical Performance: Current rating and contact material (gold-plated brass)
• Environmental Sealing: Ingress protection classification
• Material Compliance: RoHS3 compliance and contact finish specifications
• Mechanical Compatibility: Shell material, shielding, and mounting type

The substitute part S21K0C-P02MPH0-450S meets the core functional requirements of a 2-position male plug connector with solder cup termination, push-pull fastening, shielded design, and RoHS3 compliance. Variations in shell size designation, operating temperature range, and current rating represent design differences within the circular connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1K.302.CLAC45Z and S21K0C-P02MPH0-450S are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

The FGG.1K.302.CLAC45Z supports higher current capacity (15A versus 12A) and extended operating temperature range (-55°C to 200°C versus -40°C to 120°C). Applications requiring these extended electrical or thermal specifications necessitate the LEMO part.

The S21K0C-P02MPH0-450S provides equivalent 2-position solder cup connectivity with push-pull fastening and shielded design. This ODU connector is suitable for applications within its specified current and temperature parameters. The cable opening tolerance range overlaps with the main part, supporting compatible cable diameters.

Both connectors maintain IP68 waterproof classification and utilize PEEK insert material with gold-plated brass contacts, ensuring equivalent environmental sealing and electrical performance within their respective ratings.

Frequently Asked Questions (FAQ)

Q: Can the S21K0C-P02MPH0-450S directly replace the FGG.1K.302.CLAC45Z?

A: Direct replacement is possible when application requirements fall within the ODU part specifications: maximum 12A current draw and operating temperatures between -40°C and 120°C. Applications exceeding these parameters require the LEMO part.

Q: Are the solder cup terminations compatible between these connectors?

A: Both connectors feature solder cup termination with compatible cable opening ranges (4.00mm to 4.50mm overlap). Solder joint preparation and cable gauge selection follow standard circular connector practices for both parts.

Q: What is the difference in shell finish between these parts?

A: The FGG.1K.302.CLAC45Z uses chrome plating directly on brass. The S21K0C-P02MPH0-450S uses chrome plating over nickel on brass. Both finishes provide corrosion resistance; the nickel underplate in the ODU part offers additional protection in certain corrosive environments.

Q: Do both connectors meet the same compliance standards?

A: Both parts are ROHS3 compliant and REACH unaffected. Both maintain MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent for regulatory purposes.

Q: What are the cable diameter limitations for each connector?

A: FGG.1K.302.CLAC45Z accepts cables 4.10mm to 4.50mm diameter. S21K0C-P02MPH0-450S accepts cables 4.00mm to 4.50mm diameter. The ODU part accommodates slightly smaller cable diameters within the overlap range.
