Amphenol RF 901-9202-2A SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 901-9202-2A is an SMA connector jack (female socket) rated for 50 ohms impedance with solder termination for both center contact and shield. This free-hanging, in-line connector is designed for semi-rigid coaxial cable applications (RG-405, .085"/.086" diameter) and operates across a frequency range up to 6 GHz with an operating temperature range of -65°C to 165°C. The connector features beryllium copper center contacts with gold plating, a stainless steel body with gold finish, and PTFE dielectric material. With 1113 pieces currently in stock and active product status, this component is suitable for RF/microwave applications requiring reliable solder-based termination. Equivalent and substitute parts are identified for applications where alternative manufacturers, enhanced frequency performance, or different cable group compatibility are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 901-9202-2A is determined by strict adherence to the following core parameters: SMA connector style, jack (female socket) type, 50 ohm impedance, solder termination for both center contact and shield, free-hanging in-line mounting, and threaded fastening. All substitute parts must maintain these electrical and mechanical characteristics to ensure functional compatibility in the target application.

The substitute parts are grouped into two categories based on their relationship to the main part:

Direct Manufacturer Substitute (142-0593-001): This Cinch Connectivity Solutions Johnson part maintains all core electrical and mechanical parameters identical to the main part. It differs in maximum frequency capability (26.5 GHz versus 6 GHz) and body material composition (brass versus stainless steel), representing an enhanced-performance alternative suitable for higher-frequency applications within the same connector family.

Similar Manufacturer Substitutes (1046286-1, 142-0594-001, 228640-1): These parts maintain the core SMA jack 50 ohm solder-terminated configuration but introduce variations in cable group compatibility, frequency rating, operating temperature range, or termination method. Selection among these alternatives depends on specific application requirements regarding cable diameter, maximum operating frequency, and temperature extremes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Cinch Connectivity Solutions Johnson 142-0593-001

The 142-0593-001 is the direct functional equivalent to the Amphenol RF 901-9202-2A. Both parts maintain identical core electrical specifications (SMA jack, 50 ohm, solder termination) and operating temperature range (-65°C to 165°C). The 142-0593-001 is ROHS3 compliant and REACH affected, matching the regulatory status of the main part. The primary distinction is enhanced frequency capability (26.5 GHz versus 6 GHz), which provides additional performance margin for applications not requiring the full frequency range. Body material differs (brass versus stainless steel), but both materials are suitable for RF connector applications. This part is recommended for direct substitution when Amphenol RF 901-9202-2A availability is constrained.

Secondary Substitutes: TE Connectivity 1046286-1 and Cinch 142-0594-001

The TE Connectivity 1046286-1 maintains SMA jack 50 ohm solder termination with RG-405 cable group compatibility. However, the operating temperature maximum is limited to 105°C (versus 165°C), which restricts use in high-temperature applications. The 1046286-1 is not RoHS3 compliant, which may conflict with procurement requirements. This part is suitable only for applications operating within the -65°C to 105°C range without RoHS compliance mandates.

The Cinch 142-0594-001 is compatible with RG-402 cable (.141" diameter) rather than RG-405, representing a different cable group. This part maintains the full -65°C to 165°C operating temperature range and ROHS3 compliance. Selection of the 142-0594-001 is appropriate only when RG-402 cable compatibility is required.

Discontinued Part: TE Connectivity 228640-1

The TE Connectivity 228640-1 is discontinued at DiGi Electronics and features crimp shield termination rather than solder termination. This part does not meet the solder termination requirement of the main part and is not recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 142-0593-001 be used as a direct replacement for the Amphenol RF 901-9202-2A?

A: Yes. Both parts are SMA jack connectors with 50 ohm impedance, solder termination for center contact and shield, free-hanging in-line mounting, and identical operating temperature range (-65°C to 165°C). The 142-0593-001 provides enhanced frequency performance (26.5 GHz versus 6 GHz) and maintains ROHS3 compliance and REACH affected status. Mechanical and electrical compatibility is confirmed.

Q: What is the significance of the cable group designation (RG-405 versus RG-402)?

A: Cable group designation specifies the semi-rigid coaxial cable diameter for which the connector is designed. The main part (901-9202-2A) and most substitutes are rated for RG-405 cable (.085" to .086" diameter). The Cinch 142-0594-001 is rated for RG-402 cable (.141" diameter). Selection must match the cable diameter in the target application. Using a connector rated for a different cable group will result in improper fit and electrical performance degradation.

Q: Are there compliance differences between the substitute parts?

A: Yes. The Amphenol RF 901-9202-2A, Cinch 142-0593-001, and Cinch 142-0594-001 are all ROHS3 compliant and REACH affected. The TE Connectivity 1046286-1 is not RoHS3 compliant (RoHS status listed as "Not applicable"), which may disqualify it from applications with RoHS compliance requirements. The TE Connectivity 228640-1 is ROHS3 compliant but discontinued.

Q: What is the impact of operating temperature range differences?

A: The main part and Cinch substitutes operate across -65°C to 165°C. The TE Connectivity parts (1046286-1 and 228640-1) are limited to -65°C to 105°C. Applications requiring operation above 105°C must use the Amphenol RF 901-9202-2A, Cinch 142-0593-001, or Cinch 142-0594-001. Selection of a TE Connectivity part for high-temperature applications will result in connector failure or performance degradation.

Q: Why is the TE Connectivity 228640-1 not recommended despite availability?

A: The 228640-1 features crimp shield termination rather than solder termination, which is incompatible with the solder-based assembly process of the main part. Additionally, this part is discontinued at DiGi Electronics, indicating end-of-life status. New designs should not incorporate discontinued components.

Q: How do frequency ratings affect part selection?

A: The main part is rated to 6 GHz maximum frequency. Substitute parts with higher frequency ratings (142-0593-001 at 26.5 GHz, 1046286-1 and 142-0594-001 at 18 GHz) provide additional performance margin and are suitable for applications operating at or below the main part's frequency specification. Frequency rating does not limit substitution; a higher-rated part functions correctly at lower frequencies.

Q: What is the significance of body material differences (stainless steel versus brass)?

A: Both stainless steel and brass are suitable materials for RF connector bodies. Stainless steel (used in the main part and TE Connectivity substitutes) offers superior corrosion resistance. Brass (used in Cinch substitutes) provides good RF performance and is cost-effective. Material selection does not affect electrical compatibility; choice depends on environmental exposure and cost considerations.

Q: Are all substitute parts available in the same packaging format?

A: The main part and Cinch substitutes are supplied in bulk packaging. TE Connectivity parts do not specify packaging format in the provided data. Packaging differences do not affect electrical or mechanical compatibility but may influence procurement and inventory management processes.
