Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1B.307.CLAD76Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be Plug with Male Pins, 7-position configuration
• Termination Method: Solder Cup termination required
• Fastening Mechanism: Push-Pull fastening type
• Electrical Properties: Gold-plated mating contacts, shielded configuration
• Material Specifications: Brass shell with chrome finish, PEEK insert material
• Environmental Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• Mechanical Compatibility: Cable opening range and mounting type (Free Hanging, In-Line)

The substitute part S21L0C-P07MFG0-770S meets these core substitution criteria while maintaining functional equivalence for 7-position circular connector plug applications.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1B.307.CLAD76Z and S21L0C-P07MFG0-770S are Active product status connectors with full ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

The FGG.1B.307.CLAD76Z supports an extended operating temperature range of -55°C to 250°C, making it suitable for high-temperature applications. The S21L0C-P07MFG0-770S operates within -40°C to 120°C, appropriate for standard industrial and commercial environments.

Current rating specifications show the FGG.1B.307.CLAD76Z at 7A and the S21L0C-P07MFG0-770S at 7.5A. Cable opening tolerances overlap substantially (7.20-7.60mm versus 7.00-7.70mm), ensuring mechanical compatibility in most installation scenarios.

Both connectors feature identical core specifications: 7-position male pin configuration, solder cup termination, push-pull fastening, shielded design, gold-plated mating contacts, brass shells with chrome finishes, and PEEK inserts. Selection between these parts should be based on specific operating temperature requirements and current capacity needs of the target application.

Frequently Asked Questions (FAQ)

Q: Can the S21L0C-P07MFG0-770S replace the FGG.1B.307.CLAD76Z in all applications?

A: Substitution is valid for applications operating within -40°C to 120°C with current requirements up to 7.5A. Applications requiring operation below -40°C or above 120°C must use the FGG.1B.307.CLAD76Z due to its extended temperature range of -55°C to 250°C.

Q: Are the cable opening dimensions compatible between these two connectors?

A: Cable opening ranges overlap significantly. The FGG.1B.307.CLAD76Z accepts 7.20-7.60mm cables, while the S21L0C-P07MFG0-770S accepts 7.00-7.70mm cables. Cables within the 7.20-7.60mm range are compatible with both connectors.

Q: What are the key differences in shell finish specifications?

A: The FGG.1B.307.CLAD76Z features chrome finish on brass, while the S21L0C-P07MFG0-770S features chrome over nickel on brass. Both provide equivalent corrosion resistance and electrical performance for standard applications.

Q: Do both connectors meet the same compliance standards?

A: Both connectors are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both carry Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What is the primary consideration when selecting between these two 7-position circular connector plugs?

A: Operating temperature range is the primary differentiator. Select based on the minimum and maximum temperatures your application will experience. Current capacity (7A versus 7.5A) is a secondary consideration for high-current applications.
