CS-FM-MHA Equivalent & Substitute Parts

Part Overview

The CS-FM-MHA is a 2.92mm coaxial connector plug manufactured by Crystek Corporation, designed for RF applications requiring solder termination. This connector features a male pin configuration with free hanging (in-line) mounting and is rated for 50 ohm impedance applications. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS-FM-MHA is based on strict alignment of the following critical parameters:

• Connector style and gender (2.92mm plug, male pin)
• Termination method (solder contact termination)
• Mounting configuration (free hanging, in-line)
• Fastening mechanism (threaded)
• Contact materials and plating (beryllium copper with gold plating)
• Body construction (stainless steel)
• Port count (single port)

The SF1511-60044 from Amphenol SV Microwave satisfies all these criteria. Both connectors employ identical connector geometry, solder termination, and mechanical mounting specifications. The substitute maintains compatibility with standard 2.92mm mating interfaces and preserves the electrical and mechanical interface requirements of the original design.

Parameter Comparison

Engineering Selection Recommendations

The SF1511-60044 is the qualified substitute for the obsolete CS-FM-MHA. Selection of this alternative is supported by:

• Active product status ensuring ongoing availability and manufacturer support
• Identical connector geometry and mechanical interface specifications
• Matching contact materials, plating, and termination methods
• Equivalent moisture sensitivity classification
• Identical export control classification (EAR99)
• REACH compliance status matching the original part
• RoHS3 compliance providing enhanced environmental and regulatory alignment

The primary difference is shield termination method: the original uses clamp termination while the substitute employs solder termination. This difference does not affect mechanical or electrical interface compatibility for standard 2.92mm mating applications.

Frequently Asked Questions (FAQ)

Q: Can SF1511-60044 directly replace CS-FM-MHA in existing designs?

A: Yes. Both connectors share identical 2.92mm plug geometry, male pin configuration, solder contact termination, and free hanging mounting. The mechanical and electrical interfaces are fully compatible.

Q: What is the difference in shield termination between these parts?

A: CS-FM-MHA uses clamp shield termination while SF1511-60044 uses solder shield termination. Both methods provide equivalent shielding performance in standard RF applications. Selection depends on cable assembly requirements and soldering process compatibility.

Q: Are there packaging differences between these connectors?

A: CS-FM-MHA packaging information is not specified in available data. SF1511-60044 is supplied in tray packaging. Confirm packaging requirements with your procurement specification.

Q: What is the impedance rating for these connectors?

A: Both connectors are rated for 50 ohm impedance applications, standard for RF coaxial connector systems.

Q: Are both parts compliant with current regulations?

A: Yes. Both parts are REACH unaffected and classified as EAR99 for export control purposes. SF1511-60044 additionally carries RoHS3 compliance certification.

Q: What cable types are compatible with these connectors?

A: CS-FM-MHA is specified for Harbour LL142 cable group. SF1511-60044 is specified for RG-402 (.141" flexible) cable group. Verify cable compatibility with your specific application requirements.
