CS-SF-MSC SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The CS-SF-MSC is an SMA connector jack manufactured by Crystek Corporation, designed as a female socket free hanging (in-line) solder termination connector for coaxial RF applications. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance, repair, and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS-SF-MSC is determined by strict alignment of the following core parameters:

• Connector Style & Type: SMA jack, female socket configuration
• Termination Method: Solder contact termination with clamp shield termination
• Mounting Configuration: Free hanging (in-line) orientation
• Fastening: Threaded coupling mechanism
• Contact & Dielectric Materials: Beryllium copper center contact with PTFE dielectric
• Contact Plating: Gold plating on center contact
• Port Count: Single port (1)

The Amphenol RF 132127 meets all mandatory substitution criteria. Additional parameters such as impedance specification (50 Ohms), operating temperature range, and mating cycle ratings are provided by the substitute part but do not restrict substitution eligibility, as these represent enhanced or specified performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 132127 is the qualified substitute for the obsolete CS-SF-MSC based on functional equivalence across all critical connector parameters. The substitute part is currently in active production status, ensuring supply chain availability and long-term support.

The 132127 provides additional specification data including 50 Ohm impedance rating, defined operating temperature range (-65°C ~ 165°C), and 500 mating cycle rating. These specifications do not conflict with the original part's application requirements and represent standard performance characteristics for SMA connectors in this class.

Compliance status: The substitute part is RoHS3 compliant and REACH affected, compared to the original part's REACH unaffected status. Both parts carry EAR99 ECCN classification and identical HTSUS coding (8536.69.4010).

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 132127 directly replace the Crystek CS-SF-MSC in existing assemblies?

A: Yes. Both connectors share identical SMA jack female socket configuration, solder termination, clamp shield termination, free hanging mounting, and threaded fastening. The center contact material (beryllium copper), dielectric material (PTFE), and contact plating (gold) are identical. The 132127 is a functional equivalent.

Q: What is the primary difference between these two connectors?

A: The body material differs: CS-SF-MSC uses stainless steel while the 132127 uses brass with gold finish. The 132127 additionally specifies 50 Ohm impedance, operating temperature range, and mating cycle rating, which the original part does not document.

Q: Are there cable compatibility considerations?

A: The 132127 is specified for use with RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cable groups. The original CS-SF-MSC is specified for Semflex HP190 cable. Cable compatibility must be evaluated based on your specific application requirements.

Q: What is the inventory status for these parts?

A: CS-SF-MSC: 948 pieces in stock (obsolete status). Amphenol RF 132127: 704 pieces in stock (active product).

Q: Are there compliance or regulatory differences?

A: Both parts carry EAR99 ECCN classification. The 132127 is RoHS3 compliant and REACH affected, while the CS-SF-MSC is REACH unaffected. Both have MSL rating of 1 (unlimited moisture sensitivity level).
