Equivalent & Substitute Parts for Winchester Interconnect 620A608G Mini UHF Coaxial Connector

Part Overview

The Winchester Interconnect 620A608G is a Mini UHF coaxial connector jack designed for RF applications requiring female socket termination with crimp contact and shield attachment. This connector operates at frequencies up to 2 GHz and is rated for 335 V with 500 mating cycles. The part is currently in active production status with 1143 units in stock.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and environmental specifications can be maintained across different manufacturers. The primary reason for identifying alternatives is to ensure supply chain continuity, manage inventory across multiple vendors, and provide options when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Winchester Interconnect 620A608G is determined by strict alignment of the following critical parameters:

Electrical Compatibility:

• Connector style (UHF, Mini)
• Connector type (Jack, Female Socket)
• Frequency rating (2 GHz maximum)
• Voltage rating (335 V)
• Impedance classification (Non-Constant)

Mechanical Compatibility:

• Contact termination method (Crimp)
• Shield termination method (Crimp)
• Mounting type (Free Hanging/In-Line)
• Fastening type (Threaded)
• Number of ports (1)

Environmental & Compliance:

• Operating temperature range (-55°C ~ 85°C)
• Mating cycle rating (500 cycles)
• RoHS compliance status
• MSL rating (1 - Unlimited)

Physical Specifications:

• Body material (Brass)
• Body finish (Nickel)
• Dielectric material (Polyoxymethylene/POM)

The TE Connectivity AMP Connectors part 5-1814819-1 meets all critical substitution criteria. While this part carries an obsolete product status and operates with RG-58C/141A cable groups (compared to RG-59/62 for the main part), the core electrical and mechanical parameters remain equivalent for direct substitution in applications where the connector interface and RF performance are the primary selection criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Winchester 620A608G): The Winchester Interconnect 620A608G is the recommended choice for new designs and applications requiring active product support. This part maintains active production status, ensuring long-term availability and consistent manufacturing quality. RoHS compliance and unlimited MSL rating provide environmental flexibility for storage and handling. The part is suitable for RF applications operating up to 2 GHz with standard UHF Mini connector interfaces.

Substitute Selection (TE Connectivity 5-1814819-1): The TE Connectivity AMP Connectors part 5-1814819-1 is electrically and mechanically equivalent and may be used as a direct substitute when the Winchester part is unavailable. However, this part carries obsolete product status, indicating discontinued production. Substitution should be limited to existing inventory applications or situations where supply of the primary part cannot be secured. The part maintains full RoHS compliance and equivalent electrical specifications. Cable group differences (RG-58C/141A versus RG-59/62) do not affect connector interface compatibility but should be considered in cable assembly specifications.

Compliance Considerations: Both parts are RoHS compliant and carry MSL rating 1 (unlimited moisture sensitivity), making them suitable for standard industrial and commercial RF applications without special storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-1814819-1 be used as a direct replacement for the Winchester 620A608G in existing assemblies?

A: Yes. Both connectors share identical electrical and mechanical specifications including connector style, type, termination methods, frequency rating, voltage rating, operating temperature range, and mating cycle rating. The connectors are mechanically and electrically interchangeable at the interface level.

Q: What is the significance of the different cable groups (RG-59/62 versus RG-58C/141A)?

A: Cable group designation indicates the recommended cable types for assembly with each connector. These differences do not affect the connector interface itself but relate to cable impedance and physical dimensions. Cable selection should be based on the specific application requirements and system impedance specifications.

Q: Why is the TE Connectivity part marked as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part. While existing inventory may be available, long-term supply cannot be guaranteed. For new designs or applications requiring extended availability, the active Winchester part is the appropriate choice.

Q: Are there any performance differences between the two connectors?

A: No. Both connectors meet identical electrical performance specifications including frequency response (2 GHz maximum), voltage rating (335 V), and mating cycle rating (500 cycles). Operating temperature ranges are identical (-55°C ~ 85°C).

Q: What is the difference between the dielectric materials listed?

A: Both parts specify Polyoxymethylene (POM) as the dielectric material. The TE Connectivity part additionally notes "Acetal," which is the chemical name for POM. These refer to the same material and present no functional difference.

Q: Are both parts RoHS compliant?

A: Yes. Both the Winchester 620A608G and TE Connectivity 5-1814819-1 are RoHS compliant, meeting environmental and hazardous substance restrictions for commercial and industrial applications.

Q: What does MSL rating 1 mean for these connectors?

A: MSL (Moisture Sensitivity Level) rating 1 indicates unlimited moisture sensitivity, meaning these connectors do not require special moisture-controlled storage or handling procedures. They can be stored and handled under standard industrial conditions without desiccant packaging or controlled humidity environments.
