FGG.0B.309.CYCD42Z Equivalent & Substitute Parts

Part Overview

The FGG.0B.309.CYCD42Z is a 9-position circular connector plug manufactured by LEMO, featuring male pins with crimp termination and push-pull fastening. This connector is actively produced and maintains 866 units in current inventory stock. The connector is designed for free-hanging in-line applications with shielded construction and IP50 dust protection rating.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in applications where the primary part is unavailable or when alternative termination methods are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.0B.309.CYCD42Z is determined by the following critical parameters:

• Connector Configuration: 9-position male plug with push-pull fastening
• Electrical Interface: Gold-plated mating contacts on brass base material
• Mechanical Compatibility: Shielded construction with PEEK insert material
• Environmental Protection: IP50 dust protection rating
• Regulatory Compliance: ROHS3 and REACH compliance status

The substitute part S20L0C-P09MCC0-420S (ODU MINI-SNAP® L series) meets these core substitution criteria. Differences in termination method (solder cup versus crimp), current rating (4A versus 2A), and operating temperature range represent functional variations that must be evaluated within specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.0B.309.CYCD42Z and S20L0C-P09MCC0-420S maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection between these parts is determined by termination methodology and thermal operating envelope requirements.

The LEMO FGG.0B.309.CYCD42Z is specified for crimp termination with extended temperature operation from -55°C to 250°C. The ODU S20L0C-P09MCC0-420S employs solder cup termination with a reduced operating temperature range of -40°C to 120°C. Current rating differences (2A versus 4A) reflect the electrical capacity of each connector design.

Component selection must align with the specific termination process capability of the assembly operation and the thermal requirements of the target application environment.

Frequently Asked Questions (FAQ)

Q: Can the ODU S20L0C-P09MCC0-420S directly replace the LEMO FGG.0B.309.CYCD42Z?

A: Direct mechanical and electrical replacement is possible when the application termination process supports solder cup attachment and the operating temperature range does not exceed -40°C to 120°C. The 9-position configuration, push-pull fastening, shielded construction, and gold-plated contact interface are functionally equivalent.

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

A: The primary difference is termination method. The LEMO part uses crimp termination while the ODU part uses solder cup termination. Secondary differences include operating temperature range and current rating capacity.

Q: Are both connectors RoHS compliant?

A: Yes, both the FGG.0B.309.CYCD42Z and S20L0C-P09MCC0-420S are ROHS3 compliant and REACH unaffected.

Q: What packaging is available for the substitute part?

A: The ODU S20L0C-P09MCC0-420S is supplied in bulk packaging with 1005 units currently in inventory stock.

Q: Does the higher current rating of the ODU connector affect compatibility?

A: The ODU connector's 4A current rating exceeds the LEMO connector's 2A rating. This represents increased electrical capacity and does not create compatibility issues in applications designed for 2A operation.
