Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1K.308.CLAC45Z is determined by the following critical parameters:

• 8-position connector configuration
• Male pin plug connector type
• Solder cup termination method
• Push-pull fastening mechanism
• Shielded construction
• Gold-plated mating contacts
• Brass shell with chrome finish
• PEEK insert material
• ROHS3 compliance
• IP68 waterproof ingress protection capability

The substitute part S21K0C-P08MFG0-450S from ODU meets these core functional requirements while operating within acceptable parameter ranges for circular connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1K.308.CLAC45Z and S21K0C-P08MFG0-450S are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific requirements:

The FGG.1K.308.CLAC45Z supports an extended operating temperature range (-55°C to 200°C) and is suitable for high-temperature applications. The S21K0C-P08MFG0-450S provides higher current capacity (7.5A versus 5A) and includes integrated strain relief features, making it advantageous for applications requiring enhanced mechanical durability.

Both connectors maintain IP68 waterproof protection and identical 8-position solder cup configuration, ensuring functional compatibility in standard industrial and measurement applications.

Frequently Asked Questions (FAQ)

Q: Can S21K0C-P08MFG0-450S replace FGG.1K.308.CLAC45Z in all applications?

A: Substitution is valid for applications operating within -40°C to 120°C temperature range and requiring up to 7.5A current capacity. Applications requiring operation below -40°C or above 120°C require the FGG.1K.308.CLAC45Z.

Q: What are the mechanical compatibility considerations?

A: Both connectors use identical 8-position push-pull fastening and solder cup termination. Cable opening ranges overlap (4.00mm to 4.50mm), ensuring mechanical compatibility for standard cable gauges.

Q: Are there differences in shell finish specifications?

A: The FGG.1K.308.CLAC45Z uses chrome finish on brass, while the S21K0C-P08MFG0-450S uses chrome over nickel plating. Both provide equivalent corrosion resistance for IP68 waterproof applications.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What is the primary functional difference between these connectors?

A: The primary differences are operating temperature range and current rating. The FGG.1K.308.CLAC45Z supports higher temperature extremes, while the S21K0C-P08MFG0-450S provides higher current capacity and strain relief features.
