RSA-3050-B SMA Female Crimp Coaxial Connector Equivalent & Substitute Parts

Part Overview

The RSA-3050-B is an SMA connector jack with female socket configuration, rated for 50 ohms impedance and designed for free hanging (in-line) applications. This RF Industries coaxial connector features crimp termination for both center contact and shield, operating at frequencies up to 12.4 GHz with a voltage rating of 375 V. The connector is ROHS3 compliant and currently active in production with 723 pieces in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across different manufacturers, termination methods, or mounting configurations while preserving core RF performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RSA-3050-B are identified based on strict equivalence in the following core parameters: connector style (SMA), connector type (jack, female socket), impedance (50 ohms), frequency rating (12.4 GHz maximum), voltage rating (375 V), center contact material (beryllium copper with gold plating), dielectric material (PTFE), fastening type (threaded), and compliance certifications (ROHS3).

The identified substitutes differ in the following allowed variations:

901-9602-3SF (Amphenol RF): Maintains all core electrical parameters and materials. Variation occurs in contact termination method (solder instead of crimp) and mounting type (free hanging in-line, identical to main part). This substitute includes weatherproof ingress protection and specified operating temperature range (-65°C to 165°C) with 500 mating cycles.

901-9610-3 (Amphenol RF): Maintains all core electrical parameters and materials. Variations occur in contact termination method (solder instead of crimp) and mounting type (panel mount with bulkhead configuration instead of free hanging). This substitute includes weatherproof ingress protection, specified operating temperature range (-65°C to 165°C), and 500 mating cycles.

Substitution logic is based on electrical compatibility (impedance, frequency, voltage) and material compatibility (contact and dielectric materials). Termination method and mounting type variations are permitted when application requirements allow such changes.

Engineering Selection Recommendations

RSA-3050-B Selection Criteria: The RSA-3050-B is appropriate for applications requiring crimp termination on both center contact and shield. This connector is ROHS3 compliant and carries MSL 1 rating. Selection of this part is indicated when crimp-based assembly processes are specified in the design or when in-line free hanging mounting is the required configuration.

901-9602-3SF Selection Criteria: The 901-9602-3SF is appropriate for applications requiring solder termination with free hanging (in-line) mounting. This Amphenol RF connector is ROHS3 compliant, MSL 1 rated, and includes weatherproof ingress protection. The specified operating temperature range (-65°C to 165°C) and 500 mating cycle rating provide additional environmental performance data. Selection is indicated when solder termination processes are specified and in-line mounting is required.

901-9610-3 Selection Criteria: The 901-9610-3 is appropriate for applications requiring solder termination with panel mount (bulkhead) configuration. This Amphenol RF connector is ROHS3 compliant, MSL 1 rated, and includes weatherproof ingress protection. The specified operating temperature range (-65°C to 165°C) and 500 mating cycle rating provide additional environmental performance data. Selection is indicated when solder termination processes are specified and panel mount bulkhead installation is required.

All three connectors maintain electrical equivalence at 50 ohms impedance, 12.4 GHz maximum frequency, and 375 V voltage rating. Substitution decisions are based on termination method requirements (crimp versus solder) and mounting configuration requirements (free hanging in-line versus panel mount bulkhead).

Frequently Asked Questions (FAQ)

Q: Can the RSA-3050-B be substituted with 901-9602-3SF? A: Substitution is possible when the application permits solder termination instead of crimp termination. Both connectors maintain identical electrical specifications (50 ohms, 12.4 GHz, 375 V) and use the same materials (beryllium copper center contact with gold plating, PTFE dielectric). Both are free hanging (in-line) mounted. The primary difference is the contact termination method.

Q: Can the RSA-3050-B be substituted with 901-9610-3? A: Substitution is possible when the application permits solder termination and panel mount (bulkhead) configuration instead of crimp termination and free hanging mounting. Both connectors maintain identical electrical specifications (50 ohms, 12.4 GHz, 375 V) and use the same materials. The mounting type difference requires mechanical redesign of the installation interface.

Q: What is the difference between 901-9602-3SF and 901-9610-3? A: Both connectors are manufactured by Amphenol RF and share identical electrical specifications and materials. The primary difference is mounting type: 901-9602-3SF is free hanging (in-line) mounted, while 901-9610-3 is panel mount with bulkhead configuration. Both use solder termination and include weatherproof ingress protection.

Q: Are all three connectors RoHS compliant? A: Yes. The RSA-3050-B, 901-9602-3SF, and 901-9610-3 are all ROHS3 compliant. All three connectors carry MSL 1 (Unlimited) moisture sensitivity level rating.

Q: What cable groups are compatible with these connectors? A: The RSA-3050-B does not specify cable group compatibility. The 901-9602-3SF is compatible with RG-174, 179, 187, 188, and 316 cable groups. The 901-9610-3 is compatible with RG-174, 188, 188A, 316, LMR-100, and M17/119-RG174 cable groups. Cable compatibility should be verified based on specific application requirements.

Q: What is the difference in packaging between these parts? A: The RSA-3050-B is supplied in bag packaging. Both 901-9602-3SF and 901-9610-3 are supplied in bulk packaging. Packaging format may affect inventory management and assembly processes.

Q: Do the Amphenol RF substitutes include additional components? A: Yes. The 901-9602-3SF includes 6 pieces per connector: 1 connector, 1 contact, 1 ferrule, 1 heat shrink, 1 insulator, and 1 nut. The 901-9610-3 includes 8 pieces per connector: 1 connector, 1 contact, 1 ferrule, 1 heat shrink, 1 insulator, 1 lockwasher, and 2 nuts. The RSA-3050-B does not specify included components.
