FGG.0B.304.CYCD35Z Equivalent & Substitute Parts

Part Overview

The FGG.0B.304.CYCD35Z is a 4-position circular connector plug manufactured by LEMO, featuring male pins with crimp termination and push-pull fastening. This connector is classified as active product status and is designed for free-hanging in-line mounting applications. The part is shielded with gold-plated mating contacts and operates across a wide temperature range of -55°C to 250°C. Finding equivalent substitute parts is necessary when the primary part is unavailable, when inventory constraints exist, or when application requirements align with alternative connector designs that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.0B.304.CYCD35Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be a 4-position circular connector plug with male pins
• Termination Method: Crimp termination required for wire attachment compatibility
• Fastening Mechanism: Push-pull fastening type for mating interface consistency
• Current Rating: Minimum 7A to support the electrical load requirements
• Contact Finish: Gold-plated mating contacts for corrosion resistance and signal integrity
• Ingress Protection: IP50 or equivalent dust protection rating
• Mounting Configuration: Free-hanging in-line mounting type
• Compliance: ROHS3 compliant and REACH unaffected status

The substitute part S20L0C-P04PFG0-420S from ODU meets these core substitution criteria as a 4-position circular connector plug with crimp termination, push-pull fastening, gold-plated contacts, IP50 ingress protection, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.0B.304.CYCD35Z and S20L0C-P04PFG0-420S are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current procurement and deployment.

The FGG.0B.304.CYCD35Z is the primary selection when the application requires shielded connector design and extended operating temperature range from -55°C to 250°C. This part is appropriate for high-temperature industrial environments and applications requiring electromagnetic interference mitigation.

The S20L0C-P04PFG0-420S serves as a substitute when the application operates within the -40°C to 120°C temperature range and does not require shielding. This connector offers a higher current rating of 7.5A compared to the 7A rating of the primary part, and includes strain relief features. The unshielded design may be suitable for applications where EMI protection is not a critical requirement.

Selection between these parts should be based on specific application temperature requirements, shielding necessity, and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the S20L0C-P04PFG0-420S replace the FGG.0B.304.CYCD35Z in all applications?

A: The S20L0C-P04PFG0-420S is a functional substitute only when the application operates within the -40°C to 120°C temperature range and does not require shielded connector design. Applications requiring the extended temperature range of -55°C to 250°C or electromagnetic shielding must use the FGG.0B.304.CYCD35Z.

Q: What are the key compatibility factors for these connectors?

A: Both connectors share identical core specifications: 4-position configuration, crimp termination, push-pull fastening, gold-plated mating contacts, IP50 ingress protection, and PEEK insert material. These matching parameters ensure mechanical and electrical compatibility for mating interface requirements.

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

A: No. The S20L0C-P04PFG0-420S current rating of 7.5A exceeds the 7A requirement of the FGG.0B.304.CYCD35Z. Higher current ratings do not create compatibility issues and provide additional design margin for the application.

Q: Are there packaging differences between these parts?

A: The FGG.0B.304.CYCD35Z is supplied in standard packaging, while the S20L0C-P04PFG0-420S is supplied in bulk packaging. Both are new original stock with active product status.

Q: What is the significance of the shielding difference?

A: The FGG.0B.304.CYCD35Z is shielded, providing electromagnetic interference protection. The S20L0C-P04PFG0-420S is unshielded. Shielding selection depends on application environment and signal integrity requirements. Shielded connectors are necessary in high-noise electromagnetic environments.
