Key Parameters

Substitute Part Grouping Explanation

The RFSMAAJD and its substitute part RFSMAAJA are classified as parametric equivalents based on identical electrical and mechanical specifications. Both parts share the following critical substitution parameters:

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Mounting Type: Panel Mount with Bulkhead feature
• Contact and Shield Termination: Solder
• Maximum Frequency: 26.5 GHz
• Operating Temperature Range: -65°C ~ 165°C
• Voltage Rating: 335 V
• Mating Cycles: 500
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

These parameters define the functional and physical compatibility requirements for direct substitution in RF coaxial connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both RFSMAAJD and RFSMAAJA are Active products manufactured by Bulgin with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain requirements rather than technical performance differences.

The RFSMAAJD is suitable for applications requiring immediate availability with 721 pieces in current stock. The RFSMAAJA provides an alternative source with higher inventory levels at 1031 pieces, supporting larger production volumes or extended supply chain planning.

Both parts meet the same regulatory requirements, operating conditions, and performance specifications for 50 Ohm SMA panel mount bulkhead connector applications operating up to 26.5 GHz.

Frequently Asked Questions (FAQ)

Q: Can RFSMAAJA be used as a direct replacement for RFSMAAJD?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (50 Ohm impedance, 26.5 GHz maximum frequency), mechanical configuration (SMA Jack, Female Socket, Panel Mount Bulkhead), termination method (Solder), operating temperature range (-65°C ~ 165°C), voltage rating (335 V), and mating cycle rating (500). Both are ROHS3 compliant with MSL 1 rating.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: Connector Style (SMA), Connector Type (Jack, Female Socket), Impedance (50 Ohms), Mounting Type (Panel Mount Bulkhead), Termination Method (Solder for both center contact and shield), Maximum Frequency (26.5 GHz), Operating Temperature Range (-65°C ~ 165°C), Voltage Rating (335 V), and Mating Cycles (500).

Q: Are there any differences in material composition between RFSMAAJD and RFSMAAJA?

A: No. Both parts use identical materials: Beryllium Copper center contact, Stainless Steel body, and Polyetherimide (PEI) dielectric material. Housing color is Silver for both variants.

Q: What is the difference between these part numbers?

A: The RFSMAAJD and RFSMAAJA are functionally and electrically identical. The difference is limited to inventory availability, with RFSMAAJA currently stocked at higher quantities (1031 pieces versus 721 pieces).

Q: Are both parts suitable for high-frequency RF applications?

A: Yes. Both parts are rated for maximum frequency operation to 26.5 GHz and maintain 50 Ohm impedance across this frequency range, making them suitable for RF and microwave applications within this specification.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both RFSMAAJD and RFSMAAJA have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or shelf life.
