APH-SMAP-SMBP Equivalent & Substitute Parts

Part Overview

The APH-SMAP-SMBP is a coaxial adapter connector manufactured by Amphenol RF, designed to convert between SMA Plug (Male Pin) and SMB Plug (Female Socket) interfaces. This adapter operates at 50 Ohms impedance and supports frequencies up to 10 GHz in a straight, free-hanging (in-line) configuration with snap-on and threaded fastening.

The APH-SMAP-SMBP is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure continued availability for applications requiring SMA-to-SMB conversion functionality, particularly where the original part number is no longer in active production.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APH-SMAP-SMBP is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Adapter Series: SMA to SMB
• Adapter Type: Plug to Plug
• Center Gender: Female to Male
• Convert From: SMA Plug, Male Pin
• Convert To: SMB Plug, Female Socket
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Snap-On, Threaded
• Body Material: Brass
• Body Finish: Gold
• Center Contact Material: Beryllium Copper
• Dielectric Material: PTFE
• Center Contact Plating: Gold
• Operating Temperature Range: -65°C ~ 165°C

Allowable Variation Parameters:

• Frequency - Max: Substitute parts may operate at lower maximum frequencies provided the application requirement does not exceed the substitute's rated frequency
• Product Status: Active substitutes are preferred for obsolete parts
• Packaging: Variations in packaging format (Bag vs. other formats) do not affect functional compatibility
• Compliance certifications: Variations in RoHS and REACH status are acceptable based on application requirements

The substitute part 242146 meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 242146

Part 242146 is the direct functional equivalent for APH-SMAP-SMBP. Both parts are manufactured by Amphenol RF and share identical mechanical and electrical specifications for the SMA-to-SMB conversion interface, including impedance, connector genders, fastening mechanism, and operating temperature range.

The key difference is the maximum frequency specification: APH-SMAP-SMBP supports 10 GHz, while 242146 supports 4 GHz. Selection between these parts depends on the application's frequency requirement. For applications operating at or below 4 GHz, 242146 is a direct substitute. For applications requiring operation above 4 GHz up to 10 GHz, the original APH-SMAP-SMBP specification must be maintained.

Compliance Considerations:

242146 carries ROHS3 Compliant and REACH Affected designations, representing current regulatory compliance standards. APH-SMAP-SMBP carries RoHS Compliant status. Both parts are suitable for applications requiring RoHS compliance. The REACH Affected status of 242146 indicates compliance with current European chemical regulations.

Availability:

242146 is in Active product status with 1054 pieces in stock, providing superior long-term availability compared to the Obsolete APH-SMAP-SMBP (892 pieces in stock). For new designs or long-term production requirements, 242146 is the recommended selection when frequency requirements do not exceed 4 GHz.

Frequently Asked Questions (FAQ)

Q: Can 242146 be used as a direct replacement for APH-SMAP-SMBP in all applications?

A: 242146 is a direct functional equivalent for applications operating at frequencies up to 4 GHz. The APH-SMAP-SMBP supports frequencies up to 10 GHz. If your application requires operation above 4 GHz, 242146 is not suitable. Verify your application's maximum operating frequency before substitution.

Q: What is the difference between these two parts?

A: Both parts are SMA-to-SMB coaxial adapters with identical mechanical interfaces, impedance (50 Ohms), materials, and operating temperature range. The primary difference is maximum frequency: APH-SMAP-SMBP operates to 10 GHz, while 242146 operates to 4 GHz. Additionally, 242146 is in Active production status while APH-SMAP-SMBP is Obsolete.

Q: Are the connector genders and fastening types identical?

A: Yes. Both parts feature SMA Plug (Male Pin) converting to SMB Plug (Female Socket) with identical snap-on and threaded fastening mechanisms. The straight, free-hanging (in-line) mounting configuration is identical on both parts.

Q: Does packaging format affect compatibility?

A: No. Packaging format (Bag vs. other formats) does not affect the functional performance or mechanical compatibility of the adapter. The internal construction and connector specifications remain identical regardless of packaging.

Q: What compliance standards apply to each part?

A: APH-SMAP-SMBP is RoHS Compliant. 242146 is ROHS3 Compliant and REACH Affected. Both parts meet current regulatory requirements. ROHS3 represents the current revision of the RoHS directive. REACH Affected indicates compliance with European chemical substance regulations.

Q: Which part should I select for a new design?

A: If your application operates at frequencies up to 4 GHz, select 242146 (Active status, better long-term availability). If your application requires operation above 4 GHz up to 10 GHz, maintain the APH-SMAP-SMBP specification or consult with Amphenol RF for alternative high-frequency solutions.

Q: Are the materials and plating specifications identical?

A: Yes. Both parts use brass bodies with gold finish, beryllium copper center contacts with gold plating, and PTFE dielectric material. Material composition and surface finishes are identical.
