RSA-3010-C SMA Male Right Angle Crimp Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RSA-3010-C is an SMA connector plug with male pin configuration, designed for 50-ohm RF applications. This RF Industries component features right-angle free-hanging (in-line) mounting with crimp termination for both center contact and shield. The part maintains active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part is unavailable or when alternative termination methods are acceptable within system design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RSA-3010-C are qualified based on the following core parameters that determine functional equivalence:

Electrical Equivalence Parameters:

• Connector style: SMA
• Connector type: Plug, Male Pin
• Impedance: 50 Ohms
• Frequency maximum: 12.4 GHz or greater
• Operating temperature range: -65°C ~ 165°C
• Voltage rating: 500 V
• Dielectric material: Polytetrafluoroethylene (PTFE)

Mechanical Equivalence Parameters:

• Mounting type: Free Hanging (In-Line), Right Angle
• Fastening type: Threaded
• Number of ports: 1

Compliance Parameters:

• Product status: Active
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The three identified substitute parts (901-9531-2, 901-9873, 901-9880-RFX) meet all core electrical and mechanical parameters. Primary differences exist in contact termination method (solder versus crimp), housing material finish, and included accessories. These differences do not affect core RF performance when applied within specified frequency and impedance parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain ROHS3 compliance and active product status equivalent to the RSA-3010-C. Selection between the main part and substitutes is determined by termination method requirements and application-specific constraints.

RSA-3010-C (RF Industries): Specified for crimp termination on both center contact and shield. Maintains nickel body finish with brass construction. Suitable for applications requiring crimp-based assembly methods.

901-9880-RFX (Amphenol RF): Provides solder termination on center contact with crimp shield termination. Matches RSA-3010-C in body material (brass) and finish (nickel). Includes 3-piece accessory set. Frequency rating matches 12.4 GHz specification. Rated for 500 mating cycles.

901-9873 (Amphenol RF): Provides solder termination on center contact with crimp shield termination. Brass body with gold finish. Includes 5-piece accessory set. Frequency rating matches 12.4 GHz specification. Rated for 500 mating cycles.

901-9531-2 (Amphenol RF): Provides solder termination on center contact with crimp shield termination. Stainless steel body with gold finish. Includes 4-piece accessory set. Frequency rating extends to 18 GHz, exceeding RSA-3010-C specification. Includes weatherproof ingress protection. Rated for 500 mating cycles.

Frequently Asked Questions (FAQ)

Q: Can the RSA-3010-C be directly replaced with 901-9880-RFX?

A: Direct replacement is possible when the application accepts solder termination on the center contact in place of crimp termination. Both parts maintain identical impedance (50 Ohms), frequency rating (12.4 GHz), operating temperature range (-65°C ~ 165°C), and voltage rating (500 V). The shield termination remains crimp in both configurations. Physical mounting and mating interface are equivalent.

Q: What is the primary difference between 901-9873 and 901-9880-RFX?

A: The primary differences are body material and finish. 901-9873 uses brass with gold finish, while 901-9880-RFX uses brass with nickel finish. 901-9880-RFX more closely matches the RSA-3010-C in appearance (silver/nickel finish). Both parts share identical electrical specifications and frequency ratings. 901-9873 includes a contact accessory in its 5-piece set, while 901-9880-RFX includes 3 pieces.

Q: Why does 901-9531-2 have a higher frequency rating (18 GHz) than the RSA-3010-C (12.4 GHz)?

A: The 901-9531-2 is rated for 18 GHz maximum frequency, which exceeds the RSA-3010-C specification of 12.4 GHz. This higher rating does not prevent substitution in applications operating at or below 12.4 GHz. The part is suitable for both lower and higher frequency applications within its rated range. Additional features include stainless steel construction and weatherproof ingress protection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The RSA-3010-C and all three substitute parts (901-9531-2, 901-9873, 901-9880-RFX) are ROHS3 compliant. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What cable groups are compatible with the substitute parts?

A: The substitute parts (901-9531-2, 901-9873, 901-9880-RFX) are specified for use with cable groups: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. The RSA-3010-C does not specify cable group compatibility in the provided data.

Q: How many mating cycles are specified for each part?

A: The RSA-3010-C does not specify mating cycle rating. All three substitute parts (901-9531-2, 901-9873, 901-9880-RFX) are rated for 500 mating cycles.

Q: What accessories are included with each part?

A: RSA-3010-C does not specify included accessories. 901-9880-RFX includes 3 pieces (1 Connector, 1 End Cap, 1 Ferrule). 901-9873 includes 5 pieces (1 Connector, 1 Contact, 1 End Cap, 1 Ferrule, 1 Heat Shrink). 901-9531-2 includes 4 pieces (1 Connector, 1 End Cap, 1 Ferrule, 1 Heat Shrink).
