CS-SM-MSC SMA Connector Plug Equivalent & Substitute Parts

Part Overview

The CS-SM-MSC is an SMA connector plug manufactured by Crystek Corporation, designed for coaxial RF applications with male pin free hanging (in-line) solder termination. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The connector features a stainless steel body with gold-plated beryllium copper center contact and PTFE dielectric material, suitable for Semflex HP190 cable group applications.

Key Parameters

Substitute Part Grouping Explanation

The 142-0202-016 manufactured by Cinch Connectivity Solutions qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Electrical and Mechanical Criteria:

• Connector Style: SMA (identical)
• Connector Type: Plug, Male Pin (identical)
• Contact Termination: Solder (identical)
• Shield Termination: Clamp (identical)
• Mounting Type: Free Hanging (In-Line) (identical)
• Fastening Type: Threaded (identical)
• Number of Ports: 1 (identical)
• Center Contact Plating: Gold (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• ECCN Classification: EAR99 (identical)

The 142-0202-016 provides 50 Ohm impedance specification, active product status, and extended operating temperature range (-65°C to 165°C), making it suitable for applications requiring the core SMA plug solder interface defined by the CS-SM-MSC.

Parameter Comparison

Engineering Selection Recommendations

The 142-0202-016 is the identified substitute for the obsolete CS-SM-MSC based on functional equivalence across all specified connector interface parameters. The substitute part maintains active product status, ensuring continued availability and supply chain reliability. The 142-0202-016 carries RoHS Compliance certification, providing regulatory advantage for applications subject to hazardous substance restrictions. Both parts share identical ECCN classification (EAR99) and moisture sensitivity ratings, supporting equivalent handling and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 142-0202-016 directly replace the CS-SM-MSC in existing assemblies?

A: Yes. Both connectors share identical SMA plug male pin solder interface specifications, threaded fastening, clamp shield termination, and free hanging mounting configuration. The substitute maintains the same electrical interface class and physical mating geometry.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer identity and product status. The CS-SM-MSC is obsolete; the 142-0202-016 is active. The substitute specifies 50 Ohm impedance, extended operating temperature range (-65°C to 165°C), 500 mating cycles, and RoHS compliance. The CS-SM-MSC does not provide these specifications in the available data.

Q: Are there cable group compatibility considerations?

A: The CS-SM-MSC is specified for Semflex HP190 cable group. The 142-0202-016 supports RG-178 and RG-196 cable groups. Both are standard SMA plug solder configurations; cable compatibility depends on specific application requirements and connector body dimensions.

Q: What is the significance of the RoHS compliance difference?

A: The 142-0202-016 is RoHS Compliant, meeting restrictions on hazardous substances. The CS-SM-MSC RoHS status is not specified. For applications subject to RoHS requirements, the 142-0202-016 provides documented compliance.

Q: Are both parts suitable for the same frequency applications?

A: The 142-0202-016 specifies maximum frequency of 12.4 GHz. The CS-SM-MSC does not provide frequency specification. For RF applications requiring frequency performance verification, the 142-0202-016 data provides explicit frequency rating.
