FGG.1B.310.CYCD72Z Equivalent & Substitute Parts

Part Overview

The FGG.1B.310.CYCD72Z is a 10-position circular connector plug manufactured by LEMO, featuring male pins with crimp termination and push-pull fastening. This connector is designed for free-hanging in-line applications requiring shielded connections with IP50 dust protection. The part is currently active in production with 783 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to component availability, supply chain considerations, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FGG.1B.310.CYCD72Z is determined by the following critical parameters:

• Connector Configuration: 10-position circular connector plug with male pins
• Fastening Mechanism: Push-pull fastening system
• Shielding: Shielded design for EMI protection
• Contact Material & Finish: Brass with gold mating surface
• Ingress Protection: IP50 dust protection rating
• Compliance: ROHS3 and REACH compliance status

The identified substitute part S21L0C-P10MCC0-720S from ODU maintains compatibility across these core parameters. Variations in termination method (crimp versus solder cup), current rating, and operating temperature range represent design trade-offs that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1B.310.CYCD72Z and S21L0C-P10MCC0-720S maintain ROHS3 and REACH compliance, confirming regulatory equivalence for applications subject to these standards. The primary selection criteria are:

FGG.1B.310.CYCD72Z is specified when crimp termination is required and extended operating temperature range (-55°C to 250°C) is necessary for the application.

S21L0C-P10MCC0-720S is applicable when solder cup termination is acceptable and the operating temperature range of -40°C to 120°C meets application requirements. This substitute provides higher current capacity (4A versus 2.5A) and includes integrated strain relief features.

Both connectors are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can S21L0C-P10MCC0-720S replace FGG.1B.310.CYCD72Z in all applications?

A: Substitution is valid only when the application requirements align with the parameter differences. The solder cup termination of the ODU part requires different assembly procedures than the crimp termination of the LEMO part. The reduced operating temperature range (-40°C to 120°C versus -55°C to 250°C) must be verified against application specifications.

Q: What is the difference between crimp and solder cup termination?

A: Crimp termination (FGG.1B.310.CYCD72Z) uses mechanical compression to attach wires to contacts. Solder cup termination (S21L0C-P10MCC0-720S) requires soldering wires into cup-shaped contact receptacles. Each method has distinct assembly equipment and process requirements.

Q: Are both parts compatible with the same mating connectors?

A: Both connectors feature 10-position circular plug configurations with push-pull fastening and gold-plated contacts. Mechanical compatibility depends on the specific socket or receptacle design. Verify mating connector specifications with the connector manufacturer.

Q: What does IP50 ingress protection mean?

A: IP50 rating indicates dust protection. The connector is protected against limited dust ingress but is not suitable for immersion or high-pressure water spray applications.

Q: Are there packaging or MSL considerations for these parts?

A: Both parts are supplied in bulk packaging. The FGG.1B.310.CYCD72Z has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The S21L0C-P10MCC0-720S has MSL Not Applicable, indicating no moisture sensitivity classification.
