CS-FM-MSR 2.92mm Coaxial Connector Plug Equivalent & Substitute Parts

Part Overview

The CS-FM-MSR is a 2.92mm coaxial connector plug manufactured by Crystek Corporation, designed for RF applications requiring solder termination on RG-405 semi-rigid cable. This connector features a male pin configuration with free-hanging (in-line) mounting and stainless steel construction with gold-plated beryllium copper center contact.

The CS-FM-MSR is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications currently utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 145-0693-001 (Cinch Connectivity Solutions Johnson) qualifies as an equivalent based on the following critical parameters:

• Connector Style: Both parts use 2.92mm connectors
• Connector Type: Both are plug configurations with male pins
• Contact Termination: Both employ solder termination
• Mounting Type: Both feature free-hanging (in-line) mounting
• Cable Group: Both are compatible with RG-405 (.085" semi-rigid) cable
• Fastening Type: Both use threaded fastening
• Number of Ports: Both have single port configuration
• Center Contact Material: Both use beryllium copper
• Body Material: Both use stainless steel construction
• Center Contact Plating: Both feature gold plating

The 145-0693-001 provides additional specifications including impedance rating (50 Ohms), operating temperature range (-65°C to 165°C), and mating cycle rating (500 cycles), which are not specified for the CS-FM-MSR but do not conflict with its application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 145-0693-001 is the qualified substitute for the obsolete CS-FM-MSR. Selection is based on:

• Product Status: The 145-0693-001 maintains active product status, ensuring ongoing availability and manufacturer support, whereas the CS-FM-MSR is obsolete.
• Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS classifications, maintaining regulatory consistency.
• Moisture Sensitivity: Both parts carry MSL rating of 1 (Unlimited), indicating equivalent handling and storage requirements.
• Mechanical and Electrical Compatibility: The 145-0693-001 matches all critical mechanical parameters (connector style, type, mounting, cable compatibility) and provides specified electrical performance (50 Ohm impedance, operating temperature range, mating cycle rating).

The primary difference is shield termination method: the CS-FM-MSR uses clamp termination while the 145-0693-001 uses solder termination. This difference requires evaluation based on specific application assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the 145-0693-001 directly replace the CS-FM-MSR in existing assemblies?

A: The 145-0693-001 is mechanically and electrically compatible for 2.92mm RG-405 semi-rigid cable applications. The primary consideration is the shield termination method: CS-FM-MSR uses clamp termination while 145-0693-001 uses solder termination. Assembly procedures must be evaluated accordingly.

Q: What is the significance of the shield termination difference?

A: The CS-FM-MSR employs clamp-style shield termination, while the 145-0693-001 uses solder termination. Both methods provide RF shielding; however, assembly techniques and tooling requirements differ. Solder termination requires soldering equipment and procedures, whereas clamp termination uses mechanical compression.

Q: Are there packaging differences between these parts?

A: The CS-FM-MSR packaging is not specified in available data. The 145-0693-001 is supplied in bulk packaging and includes 5-piece kits containing connector, contact, coupling nut, gasket, and insulator. Verify packaging requirements for your procurement process.

Q: What operating conditions are supported by the substitute part?

A: The 145-0693-001 operates across -65°C to 165°C temperature range with 50 Ohm impedance and supports 500 mating cycles. These specifications exceed typical RF connector applications and provide margin for demanding environments.

Q: Are there any compliance or certification differences?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. The 145-0693-001 is ROHS3 compliant and REACH affected, while the CS-FM-MSR REACH status is unaffected. Verify compliance requirements for your specific application and region.
