Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS-NM-MSC is determined by strict adherence to the following core parameters:

Primary Substitution Criteria:

• Connector Style: N Type (mandatory match)
• Connector Type: Plug, Male Pin (mandatory match)
• Contact Termination: Solder (mandatory match)
• Shield Termination: Clamp (mandatory match)
• Mounting Type: Free Hanging (In-Line) (mandatory match)
• Fastening Type: Threaded (mandatory match)
• Number of Ports: 1 (mandatory match)

Secondary Compatibility Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) or equivalent
• ECCN Classification: EAR99 (regulatory alignment)
• HTSUS Code: 8536.69.4010 (tariff classification alignment)

The Winchester Interconnect model 110A108B satisfies all primary substitution criteria and maintains compatibility across secondary parameters, establishing it as a functional equivalent for the obsolete CS-NM-MSC.

Engineering Selection Recommendations

The Winchester Interconnect 110A108B is the qualified substitute for the obsolete Crystek CS-NM-MSC based on the following factors:

Product Status: The 110A108B maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete CS-NM-MSC.

Regulatory Compliance: Both connectors share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, confirming regulatory alignment. The 110A108B carries RoHS Compliant certification, providing additional environmental compliance assurance.

Functional Equivalence: All mandatory substitution parameters align precisely between the two connectors, including connector style, type, termination methods, mounting configuration, and fastening mechanism.

Operational Specifications: The 110A108B provides documented performance parameters including frequency capability (18 GHz maximum), operating temperature range (-55°C to 200°C), voltage rating (1000 V), mating cycle rating (500 cycles), and insertion loss specification (0.2 dB), enabling quantified performance validation in system applications.

Frequently Asked Questions (FAQ)

Q: What makes the Winchester Interconnect 110A108B a valid substitute for the Crystek CS-NM-MSC?

A: Both connectors share identical core specifications: N Type connector style, male pin plug configuration, solder contact termination, clamp shield termination, free hanging in-line mounting, and threaded fastening. These parameters define mechanical and electrical compatibility for direct substitution in applications originally designed for the CS-NM-MSC.

Q: Are there physical dimension differences between these connectors?

A: Dimension specifications were not provided in the technical data for either connector. Physical compatibility must be verified through detailed mechanical drawings before implementation in space-constrained applications.

Q: What is the significance of the cable group designation?

A: The CS-NM-MSC is specified for Semflex HP190 cable, while the 110A108B is specified for RG-8 and RG-213 cables. Cable group compatibility must be evaluated based on specific system requirements and existing cable infrastructure.

Q: Does the difference in center contact material affect substitution?

A: The CS-NM-MSC uses beryllium copper with gold plating; the 110A108B uses brass with nickel plating. Both material combinations are standard for N Type connectors and provide equivalent electrical performance in RF applications. Material selection should be based on specific environmental and corrosion resistance requirements.

Q: What is the significance of the RoHS Compliant status on the 110A108B?

A: RoHS Compliance indicates the 110A108B meets Restriction of Hazardous Substances regulations, providing environmental and regulatory assurance for applications subject to RoHS requirements. The CS-NM-MSC RoHS status was not specified in available data.

Q: Are there performance differences in insertion loss or frequency response?

A: The 110A108B specifies 0.2 dB insertion loss and 18 GHz maximum frequency. The CS-NM-MSC specifications for these parameters were not provided. System performance validation should be conducted if these parameters are critical to application requirements.
