APH-SMAJ-SMBP Equivalent & Substitute Parts

Part Overview

The APH-SMAJ-SMBP is a coaxial adapter connector manufactured by Amphenol RF that converts between SMA Jack (Female Socket) and SMB Plug (Female Socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 4 GHz and supports operating temperatures from -65°C to 165°C.

The APH-SMAJ-SMBP is classified as Obsolete. Identification of equivalent and substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring SMA to SMB coaxial adapter functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APH-SMAJ-SMBP is determined by the following critical parameters that must remain constant across equivalent parts:

Mandatory Matching Parameters:

• Adapter Series: SMA to SMB conversion capability
• Impedance: 50 Ohms
• Frequency - Max: 4 GHz minimum
• Operating Temperature Range: -65°C ~ 165°C minimum
• Style: Straight configuration
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Snap-On, Threaded
• Dielectric Material: Polytetrafluoroethylene (PTFE)

The substitute part 242145 maintains all mandatory parameters while operating as a reverse-polarity adapter (SMB Plug to SMA Jack instead of SMA Jack to SMB Plug). Both parts provide equivalent electrical performance and mechanical compatibility within the SMA to SMB adapter category.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 242145 is recommended for applications requiring SMA to SMB coaxial adapter functionality. The following factors support this selection:

Product Status: Part 242145 maintains Active product status, ensuring continued manufacturing support and availability. The APH-SMAJ-SMBP is classified as Obsolete and should be replaced in new designs and procurement activities.

Compliance and Certifications: Part 242145 meets ROHS3 compliance requirements, representing a more current regulatory standard than the RoHS Compliant designation of the APH-SMAJ-SMBP. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Electrical and Mechanical Equivalence: Both parts maintain identical impedance (50 Ohms), frequency rating (4 GHz), operating temperature range (-65°C ~ 165°C), and mechanical configuration (Straight, Free Hanging, Snap-On/Threaded fastening).

Center Contact Material Difference: The APH-SMAJ-SMBP uses Phosphor Bronze center contact material, while 242145 uses Beryllium Copper. Both materials provide equivalent electrical performance within the specified frequency and impedance parameters.

Connector Gender Configuration: The APH-SMAJ-SMBP converts from SMA Jack (Female Socket) to SMB Plug (Female Socket) with Female to Male center gender. Part 242145 reverses this configuration, converting from SMB Plug (Female Socket) to SMA Jack (Female Socket) with Female to Female center gender. Selection between these parts depends on the specific mating connector configuration required in the application.

Frequently Asked Questions (FAQ)

Q: Can 242145 directly replace APH-SMAJ-SMBP in existing applications?

A: Direct replacement depends on connector gender requirements. The APH-SMAJ-SMBP provides Female to Male center gender conversion, while 242145 provides Female to Female center gender conversion. Both parts maintain identical electrical specifications (50 Ohms, 4 GHz maximum frequency) and mechanical mounting characteristics. Verify the mating connector configuration in your application before selection.

Q: What is the significance of the center contact material difference between these parts?

A: The APH-SMAJ-SMBP uses Phosphor Bronze center contact material, while 242145 uses Beryllium Copper. Both materials meet the electrical performance requirements for 50 Ohm, 4 GHz operation. Material selection does not affect impedance, frequency response, or operating temperature range within the specified parameters.

Q: Why is APH-SMAJ-SMBP classified as Obsolete?

A: The APH-SMAJ-SMBP is no longer in active production. Part 242145 is the current Active equivalent offering from Amphenol RF for SMA to SMB coaxial adapter applications. New designs and procurement should utilize 242145 to ensure long-term availability and support.

Q: Are there packaging differences between these parts?

A: The APH-SMAJ-SMBP packaging is not specified in available documentation. Part 242145 is supplied in Bag packaging. Contact the manufacturer for specific packaging requirements for the APH-SMAJ-SMBP if historical stock is being sourced.

Q: Do both parts meet current regulatory compliance standards?

A: Both parts are RoHS compliant. Part 242145 specifically meets ROHS3 compliance, representing the current regulatory standard. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications for export and tariff purposes.

Q: What is the maximum operating frequency for these adapters?

A: Both the APH-SMAJ-SMBP and 242145 are rated for maximum frequency operation of 4 GHz. This frequency rating applies across the full operating temperature range of -65°C to 165°C.

Q: Are these adapters suitable for high-temperature applications?

A: Both adapters support operating temperatures from -65°C to 165°C, making them suitable for applications requiring extended temperature range operation. The Polytetrafluoroethylene (PTFE) dielectric material and gold-plated brass construction maintain performance across this temperature range.
