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

Part Overview

The CS-SM-MHA is an SMA connector plug manufactured by Crystek Corporation, designed for coaxial RF applications requiring solder termination. This component features a male pin configuration with free-hanging (in-line) mounting and stainless steel construction with gold-plated beryllium copper contacts. The part is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 142-0202-016 (Cinch Connectivity Solutions) qualifies as a functional equivalent based on the following critical parameters:

Matching Parameters:

• Connector Style: SMA (identical RF interface standard)
• Connector Type: Plug, Male Pin (identical mating configuration)
• Contact Termination: Solder (identical assembly method)
• Shield Termination: Clamp (identical shielding approach)
• Mounting Type: Free Hanging (In-Line) (identical mechanical installation)
• Fastening Type: Threaded (identical coupling mechanism)
• Number of Ports: 1 (identical port count)
• Center Contact Plating: Gold (identical contact surface)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental rating)

The 142-0202-016 maintains full mechanical and electrical interface compatibility with the CS-SM-MHA, enabling direct substitution in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The 142-0202-016 is the recommended substitute for the obsolete CS-SM-MHA based on the following factors:

Product Status: The 142-0202-016 maintains active production status with current inventory availability (789 pcs), ensuring long-term supply continuity for legacy system support and repair operations.

Compliance & Certifications: The 142-0202-016 is RoHS Compliant, meeting modern environmental and regulatory requirements. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, confirming equivalent export and tariff treatment.

Environmental & Performance Specifications: The 142-0202-016 provides documented operating temperature range (-65°C ~ 165°C), voltage rating (170 V), mating cycle rating (500), and maximum frequency (12.4 GHz), offering measurable performance data absent from the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the 142-0202-016 be used as a direct replacement for the CS-SM-MHA in existing assemblies?

A: Yes. Both connectors share identical SMA connector style, male plug configuration, solder termination method, clamp shield termination, threaded fastening, and free-hanging mounting type. No mechanical or electrical modifications are required.

Q: What are the key differences between these two parts?

A: The primary differences are center contact material (beryllium copper vs. brass), body material (stainless steel vs. brass with nickel finish), and dielectric material composition. The 142-0202-016 provides documented performance specifications (operating temperature, voltage rating, mating cycles, frequency) not specified for the CS-SM-MHA.

Q: Is the 142-0202-016 suitable for high-frequency RF applications?

A: The 142-0202-016 is rated to 12.4 GHz maximum frequency, supporting standard RF and microwave applications within this bandwidth. Verify your specific frequency requirements against this specification.

Q: What is the packaging difference between these parts?

A: The CS-SM-MHA packaging is not specified. The 142-0202-016 is supplied in bulk packaging and includes six component pieces per connector (connector body, clamp cone, clamp nut, clamp stem, contact, and insulator).

Q: Are both parts environmentally compliant?

A: Both parts carry identical Moisture Sensitivity Level 1 (Unlimited) ratings. The 142-0202-016 is explicitly RoHS Compliant. The CS-SM-MHA compliance status is not specified.

Q: What is the cable compatibility for the 142-0202-016?

A: The 142-0202-016 is compatible with RG-178 and RG-196 cable groups, supporting standard 50-ohm coaxial cable assemblies.
