310B205N Equivalent & Substitute Parts Reference

Part Overview

The 310B205N is a BNC straight connector manufactured by Winchester Interconnect, designed for 75-ohm coaxial cable applications. This free-hanging (in-line) crimp connector operates at frequencies up to 1 GHz and is rated for 500 volts with 500 mating cycles. The connector features a bayonet lock fastening mechanism and weatherproof ingress protection, making it suitable for RF signal transmission in industrial and telecommunications applications. As an active product with RoHS compliance and MSL Level 1 rating, the 310B205N remains in current production with 1056 units available in inventory.

Identifying equivalent and substitute parts becomes necessary when addressing supply chain constraints, lead time requirements, or specific application compatibility needs while maintaining electrical and mechanical performance standards.

Electrical Compatibility Requirements:

• Connector Style: BNC (bayonet lock mechanism)
• Impedance: 75 Ohms (RF signal integrity)
• Frequency Maximum: 1 GHz or greater
• Voltage Rating: 500 V or greater
• Insertion Loss: 0.2 dB or lower

Mechanical Compatibility Requirements:

• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Cable Group: RG-179 compatible

Environmental & Compliance Requirements:

• Ingress Protection: Weatherproof
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Mating Cycles: 500 or greater

Material Specifications:

• Body Material: Brass
• Body Finish: Nickel

Substitute parts must match all parameters listed above. No deviations from these specifications are permitted for direct substitution.

Parameter Comparison

No substitute parts have been provided in the input data. The substitute part list field indicates "Similar null," meaning no equivalent or alternative components are currently available for comparison against the 310B205N.

When substitute parts become available, this section will present a detailed HTML table comparing all common parameters between the main part and identified alternatives, organized by electrical, mechanical, and compliance categories.

Engineering Selection Recommendations

The 310B205N maintains active product status with full RoHS compliance and MSL Level 1 rating, indicating unrestricted moisture sensitivity handling. Current inventory of 1056 units supports immediate procurement without lead time constraints.

Selection of any substitute component must be based on:

• Verification of identical BNC bayonet lock connector style
• Confirmation of 75-ohm impedance specification
• Validation of crimp termination for both contact and shield
• Confirmation of free-hanging (in-line) mounting configuration
• Verification of RoHS compliance status
• Confirmation of weatherproof ingress protection rating

No substitute parts are currently documented for this reference. Direct procurement of the 310B205N is recommended when this connector specification is required.

Frequently Asked Questions (FAQ)

Q: What makes the 310B205N suitable for RF applications?

A: The 310B205N is a 75-ohm BNC connector with maximum frequency rating of 1 GHz and insertion loss of 0.2 dB, meeting standard RF coaxial transmission requirements for video, data, and signal applications.

Q: Can the 310B205N be used with cable types other than RG-179?

A: The 310B205N is specified for RG-179 cable group. Substitute parts must maintain compatibility with this cable specification. Use of non-specified cable types may result in impedance mismatch and signal degradation.

Q: What is the significance of the crimp termination method?

A: Crimp termination provides permanent, gas-tight connections without solder, ensuring consistent impedance and reducing thermal stress on components. Both contact and shield use crimp termination in the 310B205N.

Q: Does the 310B205N require special handling due to its MSL rating?

A: The MSL Level 1 rating indicates unlimited moisture sensitivity, meaning no special moisture control measures are required during storage, handling, or assembly.

Q: What is the mating cycle rating and why is it important?

A: The 500 mating cycle rating indicates the connector can withstand 500 connect/disconnect operations while maintaining electrical and mechanical specifications. This rating should match or exceed application requirements.

Q: How does the bayonet lock fastening mechanism function?

A: The bayonet lock provides quick-connect and quick-disconnect capability through a quarter-turn rotational motion, ensuring secure mating without tools while maintaining consistent contact pressure.

Q: Are there any packaging considerations for the 310B205N?

A: The connector includes three components per unit: one connector body, one contact, and one ferrule. Verify packaging quantity requirements for your application.
